1 00:00:00,060 --> 00:00:01,940 So let us start building up our application. 2 00:00:02,150 --> 00:00:05,880 So first thing that we going to do is to include all the many dignified you. 3 00:00:05,890 --> 00:00:10,950 So if you go to a board support package for an interim controller, the recommended rivalries are in 4 00:00:10,950 --> 00:00:13,800 D.C. and for GPA, which is GPA, right? 5 00:00:14,220 --> 00:00:15,030 So we'll go ahead. 6 00:00:15,180 --> 00:00:21,840 We proceed to include both the magnitude driver for I in D.C. we just need to add and perfect size X 7 00:00:21,840 --> 00:00:25,170 and then the tax rate for GPA. 8 00:00:25,290 --> 00:00:28,620 We again proceed in a similar fashion to X GPA. 9 00:00:28,620 --> 00:00:29,520 You got h. 10 00:00:30,150 --> 00:00:37,110 And the last driver file that we required to get in hardware related information is experimental start 11 00:00:37,110 --> 00:00:37,650 started raped. 12 00:00:38,010 --> 00:00:46,860 So we first proceed with initialization of the GPI opposing right so white and GPA you and it again, 13 00:00:46,860 --> 00:00:48,900 the process will remain exactly similar. 14 00:00:49,500 --> 00:00:56,220 So we need to declare to structure, conflict structure and the infrastructure so we go to the GPA driver. 15 00:00:56,910 --> 00:01:03,330 And here we have a config structure, so we'll be declaring it over here, right? 16 00:01:03,330 --> 00:01:04,530 And this should be a pointer. 17 00:01:04,530 --> 00:01:09,900 So I'll consecrate this is what we will be naming our config structure. 18 00:01:10,170 --> 00:01:11,880 Then we required an instant structure. 19 00:01:13,220 --> 00:01:21,320 So as we declare our conflict structure and internal structure, we go ahead and call look up Confederate, 20 00:01:21,330 --> 00:01:23,690 so this will lead to conflict structure for us. 21 00:01:24,080 --> 00:01:31,130 So truepill config will be equal to the look upon figure and here we need to pass the device idea. 22 00:01:31,130 --> 00:01:35,960 So to get the device ID, you just need to go to an experimental dotage wrest control. 23 00:01:35,960 --> 00:01:38,420 NF and Typekit UPI. 24 00:01:38,460 --> 00:01:38,810 Right. 25 00:01:38,810 --> 00:01:42,000 So here we have our device, right? 26 00:01:42,050 --> 00:01:45,920 So this is what we're going to add as an argument to the look config. 27 00:01:46,460 --> 00:01:49,860 The next step is to call CFG initially. 28 00:01:49,900 --> 00:01:56,000 So here we have our see if you initialize and this returns the status of initialization, right? 29 00:01:56,270 --> 00:01:57,290 So we go ahead. 30 00:01:57,530 --> 00:02:04,340 We declared one variable which renamed as status, and this code initialize required three argument 31 00:02:04,340 --> 00:02:07,220 first run in Steubenville, which is instant structure. 32 00:02:07,580 --> 00:02:14,510 Then the config structure and the last thing that it requires is a be said for a state to be said. 33 00:02:14,510 --> 00:02:18,110 This could be added from the parameter dirty trailer. 34 00:02:18,140 --> 00:02:24,200 The config structure itself consists of the B surface rate, so we'll just be invoking looking this 35 00:02:24,200 --> 00:02:25,040 address from it. 36 00:02:26,060 --> 00:02:30,170 And they will verify whether initialization is successful or not great. 37 00:02:30,200 --> 00:02:35,210 So since Dubai is a very simple, very fair, we do not need to perform a test for it, right? 38 00:02:35,630 --> 00:02:42,380 So SSD sexists look, in that case, we could just mention that. 39 00:02:43,920 --> 00:02:49,260 Cuba will reflect success rate again. 40 00:02:49,320 --> 00:02:53,580 Do not forget to add a new line character and we can just mention. 41 00:02:55,420 --> 00:02:59,230 GPA or their net, right? 42 00:03:00,040 --> 00:03:04,150 This complete the process of initialization, all five GPO now here. 43 00:03:04,390 --> 00:03:09,400 One thing we could do is since we are working on any job, we could set the direction for our pin in 44 00:03:09,400 --> 00:03:13,660 the initialization function itself, so we do not wait for an interrupt occur. 45 00:03:13,660 --> 00:03:15,370 And then we set up that addiction rate. 46 00:03:15,850 --> 00:03:20,770 So we go ahead and look for the EPA, which could be used to say detection, right? 47 00:03:20,780 --> 00:03:23,680 So this is an EPA that could be used to set the direction. 48 00:03:24,140 --> 00:03:27,400 No first argument is an instance structure. 49 00:03:27,400 --> 00:03:28,440 Then the China number. 50 00:03:28,450 --> 00:03:32,630 Remember, we are utilizing only a single China and then the addiction rate. 51 00:03:32,650 --> 00:03:35,650 So to say any of the pain as an input. 52 00:03:35,680 --> 00:03:39,400 We need to apply one and to set any of the bills and output. 53 00:03:39,400 --> 00:03:41,830 We need to apply zero rate to remember this effect. 54 00:03:42,160 --> 00:03:43,000 Now we go ahead. 55 00:03:43,480 --> 00:03:44,840 We call this API. 56 00:03:45,070 --> 00:03:51,850 The first argument is an instant structure, which is studio, then the chain and number, which is 57 00:03:51,850 --> 00:03:52,210 one. 58 00:03:52,510 --> 00:03:53,500 OK, and then election. 59 00:03:53,510 --> 00:04:00,490 Since we want to set the 16 points as an input, we'll just be adding f f right to four hexadecimal 60 00:04:00,490 --> 00:04:02,710 digits basically is equivalent to 16. 61 00:04:02,710 --> 00:04:02,950 What? 62 00:04:03,010 --> 00:04:03,300 Right? 63 00:04:04,390 --> 00:04:09,910 So this will set up the direction, so here we are performing initialization and we also set up the 64 00:04:09,910 --> 00:04:10,430 direction. 65 00:04:10,480 --> 00:04:15,130 Right now, we will be calling GPIO an 18 hour meeting application. 66 00:04:16,500 --> 00:04:22,230 So this complete all the steps that we need to perform to correctly initialize GPI opposite. 67 00:04:22,320 --> 00:04:27,690 Now we proceed to perform an initialization of an internal controller, right? 68 00:04:27,930 --> 00:04:32,730 And in line with the initialization will also be performing the different configuration right. 69 00:04:32,850 --> 00:04:37,670 We already discussed about discharge, so we'll take the help of this chart to build up our. 70 00:04:37,950 --> 00:04:38,240 Great. 71 00:04:38,700 --> 00:04:42,880 So first step is to perform an initialization of an intra controller. 72 00:04:42,900 --> 00:04:48,240 So we go ahead and we explore and I see driver file, right? 73 00:04:48,850 --> 00:04:51,870 Again, if you notice it consists of. 74 00:04:53,140 --> 00:04:59,440 The config structure and incident structure, right, I if you didn't lose the base which are available, 75 00:04:59,740 --> 00:05:02,860 so we do not have something else to look up config. 76 00:05:04,310 --> 00:05:09,610 So we do not have something I see of Jeanne, as you look up configures there, legacy of initializes 77 00:05:09,610 --> 00:05:13,400 is not there, so we'll proceed to use and initialise API. 78 00:05:13,430 --> 00:05:18,950 Again, this just required an instant structure, so we just need to declare an instant structure for 79 00:05:18,950 --> 00:05:19,850 an initial controller. 80 00:05:19,880 --> 00:05:22,540 We do not need to declare the config structure right. 81 00:05:22,550 --> 00:05:23,190 So exciting. 82 00:05:23,960 --> 00:05:27,290 And we'll just be naming this as I in D.C., right? 83 00:05:28,410 --> 00:05:33,810 We declared void, and then they did just name this as I NDC in it, right? 84 00:05:34,230 --> 00:05:37,710 This could be used to initialize our entire controller, so we call. 85 00:05:38,890 --> 00:05:39,910 They initialize. 86 00:05:40,220 --> 00:05:45,700 OK, and this basically required an instant structure and the device they rate and designate and the 87 00:05:45,700 --> 00:05:46,110 status. 88 00:05:46,110 --> 00:05:52,690 So since this state is the rebel leaders local to Dubai owned it, we could use the same name for the 89 00:05:52,690 --> 00:05:55,480 studio's variable in I in the seen it also, right? 90 00:05:55,480 --> 00:06:02,380 So I in see initialize and this required first argument as an INTC instance structure. 91 00:06:02,620 --> 00:06:05,180 And the next one is the device, right? 92 00:06:05,230 --> 00:06:08,980 So to get the device, I we just need to go to X parameter dot each file. 93 00:06:09,340 --> 00:06:11,500 Look for AI and DC and. 94 00:06:12,560 --> 00:06:15,890 Here you have your device, 84 or 93. 95 00:06:16,190 --> 00:06:23,090 That is one we night as an argument to an initialize function, then we need to for whether the initialization 96 00:06:23,090 --> 00:06:24,170 is successful or not. 97 00:06:24,170 --> 00:06:27,350 So we'll just be copying this same logic over here. 98 00:06:27,560 --> 00:06:35,300 Only thing that we need to modify is it should be in and it's successful or I envision it free right 99 00:06:35,810 --> 00:06:37,440 now for an intro controller. 100 00:06:37,460 --> 00:06:40,780 We could also perform the services that will always be a good idea. 101 00:06:40,820 --> 00:06:45,200 So we go to an AI in DC and then we have this set straight. 102 00:06:45,470 --> 00:06:48,950 This just required as an instance structure as an argument. 103 00:06:48,950 --> 00:06:50,390 So we go ahead. 104 00:06:50,660 --> 00:06:56,420 Again, we will have the the value of the status so that it stored the status of a self. 105 00:06:56,420 --> 00:06:58,960 Does that we are performing within a controller, right? 106 00:06:58,970 --> 00:07:02,370 So this required just an instant structure. 107 00:07:02,400 --> 00:07:03,560 That is what we going to add. 108 00:07:03,590 --> 00:07:09,980 And again, we will be performing the check whether student is equal status to success. 109 00:07:09,980 --> 00:07:16,490 And if that is the case, we will be mentioning that I in DC, no self test is successful. 110 00:07:16,760 --> 00:07:17,510 This makes sense. 111 00:07:18,200 --> 00:07:21,170 So this complete the process of initialization. 112 00:07:21,170 --> 00:07:26,600 What we are doing is we are performing initialization and we are running the self test right now will 113 00:07:26,840 --> 00:07:31,670 perform the different step that is used for our configuration of an internal controller, right? 114 00:07:31,970 --> 00:07:35,870 So after 90 ce initialization, no, this consists of two steps. 115 00:07:35,870 --> 00:07:42,200 Remember, first one is performing an initialization and second one is performing, so we could see 116 00:07:42,200 --> 00:07:43,840 this consists of two step. 117 00:07:43,850 --> 00:07:47,060 The first step is to initialize. 118 00:07:49,290 --> 00:07:53,640 Right, and the second step will be to perform sell this. 119 00:07:54,690 --> 00:08:00,360 OK, now we could proceed to our next tip that is enabling an exception handler, OK, so exception 120 00:08:00,360 --> 00:08:02,850 in our case will be an interest rate. 121 00:08:03,060 --> 00:08:09,120 So we go ahead and we look for the exception handler EPA right? 122 00:08:09,360 --> 00:08:12,990 So all the exception related EPA is are available in jail. 123 00:08:14,080 --> 00:08:21,040 Exception, daughter trait, so you need to include this hated flight, and then we'll look for the 124 00:08:21,040 --> 00:08:22,460 apps that are available, right? 125 00:08:23,450 --> 00:08:25,370 So here you have an interrupted. 126 00:08:25,880 --> 00:08:32,960 So first step is to initialize our exception handler, and for that we have the API, right, so we 127 00:08:32,960 --> 00:08:34,940 need to call and select ception in it. 128 00:08:35,300 --> 00:08:38,180 And this will automatically perform an initialization, right? 129 00:08:38,570 --> 00:08:43,850 So we'll go ahead and we perform initialization by calling this Zebpay. 130 00:08:43,880 --> 00:08:45,620 This does not require any argument. 131 00:08:45,660 --> 00:08:45,830 Right. 132 00:08:45,860 --> 00:08:52,100 So we do not need to do anything, then we need to specify the exception type, right? 133 00:08:52,100 --> 00:08:54,830 And that could be done with the help of registering the right. 134 00:08:54,840 --> 00:08:56,050 So this required an IED. 135 00:08:56,060 --> 00:09:02,910 ID is used to recognize the type of an exception, then an exception handler and finally ID, right? 136 00:09:02,930 --> 00:09:04,220 So we copy this. 137 00:09:05,000 --> 00:09:06,380 We go back to our mean code. 138 00:09:06,860 --> 00:09:07,190 OK. 139 00:09:07,400 --> 00:09:09,350 An IED for an interrupt. 140 00:09:09,350 --> 00:09:10,680 Is this one right? 141 00:09:10,750 --> 00:09:12,740 Exceptionally so with the exception. 142 00:09:12,740 --> 00:09:18,200 IED i I.A. is defined for all the processor, but with the different value, and this is an exception 143 00:09:18,200 --> 00:09:19,550 ID for an interest rate. 144 00:09:19,880 --> 00:09:25,250 So we'll be calling it going back to an halol, and this will serve as a first argument for us. 145 00:09:25,580 --> 00:09:33,140 The second argument is and handler for this case rate and remember that Enock is the master handler 146 00:09:33,140 --> 00:09:35,570 will be i INDC that is in control, right? 147 00:09:35,580 --> 00:09:41,780 So if you go to an AI in DC header file, you have an interrupt handler and that will be serving as 148 00:09:41,780 --> 00:09:43,640 an introvert handler for an interest rate. 149 00:09:43,970 --> 00:09:44,960 So we go ahead. 150 00:09:44,990 --> 00:09:50,340 We add this interrupt handler over here, and the good idea will be to always perform a typecasting 151 00:09:50,340 --> 00:09:51,770 related exception. 152 00:09:52,610 --> 00:09:55,730 Expect the second argument to be in this format. 153 00:09:55,970 --> 00:09:58,840 So we'll just be performing the typecasting rate. 154 00:09:58,850 --> 00:10:01,640 So here we will be adding it over here, right? 155 00:10:01,640 --> 00:10:06,320 So we are performing typecasting, and the interrupt handler for us is the master interrupt handler 156 00:10:06,710 --> 00:10:07,470 that we have in. 157 00:10:07,510 --> 00:10:10,100 And I think the last is the redirect required. 158 00:10:10,100 --> 00:10:16,010 So this will be and I think, OK, which is an instance structure for it in Japan, right? 159 00:10:16,280 --> 00:10:21,170 So once this is done, we just need to now enable so we initialize an exception. 160 00:10:21,470 --> 00:10:24,290 We define that type of an exception. 161 00:10:24,360 --> 00:10:27,590 The next step is to enable an exception rate and to do that. 162 00:10:27,830 --> 00:10:30,050 We also have an API over here, right? 163 00:10:30,090 --> 00:10:36,350 This, again, do not require any argument, so we'll just be calling it going ahead at it over here, 164 00:10:36,380 --> 00:10:36,650 right? 165 00:10:36,890 --> 00:10:41,710 So this complete the step one all fire solution. 166 00:10:41,780 --> 00:10:46,730 OK, so I in DC, initialization is already completed and enable exception. 167 00:10:46,730 --> 00:10:48,200 Handler is also great. 168 00:10:49,850 --> 00:10:55,570 The next step is to specify the type of an entrance and the hang for it, right? 169 00:10:55,810 --> 00:10:59,900 So we specified a master in Japan Labor, a handler over here. 170 00:11:00,110 --> 00:11:03,740 But then that interrupt handler could have a multiple entrance. 171 00:11:03,860 --> 00:11:08,930 Right now, we need to correctly specify that this is an interruption for that in. 172 00:11:09,230 --> 00:11:11,630 This is and function which will act as an handler, right? 173 00:11:11,930 --> 00:11:14,630 And to do that, we need to write the call great. 174 00:11:14,630 --> 00:11:15,410 So we go ahead. 175 00:11:16,040 --> 00:11:20,900 And then the first API that we have is connect, right? 176 00:11:21,170 --> 00:11:23,210 So this will specify the. 177 00:11:24,360 --> 00:11:31,050 Function handler for the specific source of an interest rate, so we just call this function. 178 00:11:32,550 --> 00:11:40,340 OK, so first argument, if you can see is an A.C. pointer, right? 179 00:11:40,350 --> 00:11:41,730 So that is an integer structure. 180 00:11:41,740 --> 00:11:47,010 So we'll just call and see then the unique idea that you have for an interrupt. 181 00:11:47,030 --> 00:11:50,600 So if you analyze the second argument is an IED, right? 182 00:11:50,620 --> 00:11:55,740 So this is how we recognize the different sources of an interest rate so far each and job that you add 183 00:11:55,980 --> 00:11:58,440 to an idea and you get an unique IED. 184 00:11:58,590 --> 00:12:01,590 And that is how we recognize the source of an interstate. 185 00:12:01,830 --> 00:12:05,100 So to get an IED again, this is hardware related information. 186 00:12:05,100 --> 00:12:09,310 So we go to an experimental stage and you just need to look for a vector. 187 00:12:09,460 --> 00:12:16,410 So we have added an enter for a GPIO, so you just need to find out the key word Cupido, unless correct? 188 00:12:16,480 --> 00:12:16,730 Right. 189 00:12:16,740 --> 00:12:19,410 So that they just go ahead and try to find out. 190 00:12:19,410 --> 00:12:19,860 Vector. 191 00:12:20,240 --> 00:12:20,550 OK. 192 00:12:20,850 --> 00:12:25,590 And here you will see we have an intra flora GPO and this is a vector idea, right? 193 00:12:25,590 --> 00:12:30,570 So this will serve as and unique ID for the GPI interest rate. 194 00:12:30,570 --> 00:12:33,240 That is what we're going to add as the second argument. 195 00:12:33,270 --> 00:12:38,810 The third argument I'd have is if you have this unique idea that is an integer from this source, OK, 196 00:12:38,820 --> 00:12:40,440 what should be the handler? 197 00:12:40,440 --> 00:12:42,110 So first, we'll just be copying this. 198 00:12:42,110 --> 00:12:45,120 So this will act as a type for us. 199 00:12:45,180 --> 00:12:45,470 OK. 200 00:12:45,930 --> 00:12:47,190 So this will be. 201 00:12:48,770 --> 00:12:55,340 And then the handler for us will be later just declared one function that will act as an handler for 202 00:12:55,340 --> 00:12:55,750 us, right? 203 00:12:55,760 --> 00:12:56,780 So GPIO. 204 00:12:58,160 --> 00:13:04,340 And so this is a function that we want to call when we have an interest rate, so we'll just be calling 205 00:13:04,340 --> 00:13:04,970 this handler. 206 00:13:05,360 --> 00:13:08,480 We go back to a clinic function and we added, We're here, right? 207 00:13:08,510 --> 00:13:14,420 The last argument is whether we want to store any detail or get any data when we have an interest in 208 00:13:14,420 --> 00:13:16,780 this case, we could just add zero rate. 209 00:13:16,890 --> 00:13:18,140 This doesn't affect us. 210 00:13:18,290 --> 00:13:18,710 Zero. 211 00:13:19,130 --> 00:13:25,340 Or you could just add the instant structure of a GPI, or that is the D Day if you want to get it right. 212 00:13:26,180 --> 00:13:32,470 So this complete specifying the unique ID for an injury and the handler when that interpreter. 213 00:13:32,480 --> 00:13:32,780 Right. 214 00:13:33,680 --> 00:13:37,610 The next step is to close this just so we go ahead. 215 00:13:39,420 --> 00:13:44,610 So to close the switch, we have this in Libya, right, so that is what we're going to call over here 216 00:13:44,610 --> 00:13:47,690 and this required again, and it's just such a unique idea, right? 217 00:13:48,030 --> 00:13:53,700 So we go ahead and we copy this to argument, and these are the same argument that this function also 218 00:13:53,700 --> 00:13:54,080 requires. 219 00:13:54,270 --> 00:13:58,050 Now what this will do is this will automatically close this switch. 220 00:13:58,050 --> 00:14:04,000 Nowhere in D.C. could receive the interest from a benefit, provided that this, which is also closed 221 00:14:04,050 --> 00:14:05,760 straight to enable input to. 222 00:14:05,880 --> 00:14:06,470 I see. 223 00:14:08,430 --> 00:14:15,090 So now we could look for this very, very specific function that could be used to close the switch on 224 00:14:15,090 --> 00:14:16,320 the peripheral tribal area. 225 00:14:16,410 --> 00:14:18,510 So if the area available, you need to add it. 226 00:14:18,530 --> 00:14:21,900 If they are not available, you are ready to proceed, right? 227 00:14:22,080 --> 00:14:27,220 So we'll go ahead and look for the GPIO tribal fight rate. 228 00:14:27,230 --> 00:14:30,930 So here you could see we have two functions. 229 00:14:30,930 --> 00:14:35,170 So one is global enabled and next one is an interest rate. 230 00:14:36,090 --> 00:14:42,170 Whenever you see both, the EPA is have a label that is global enabled as well as it, but in that case, 231 00:14:42,180 --> 00:14:48,020 OK, you need to add both Dizzy Bay to close our second switch, right? 232 00:14:48,030 --> 00:14:51,270 So first, which could be closed by just calling I indiscernible. 233 00:14:51,570 --> 00:14:56,040 Let me just call Global Enable first, and this required an instant structure, right? 234 00:14:56,430 --> 00:14:57,390 So we go ahead. 235 00:14:58,940 --> 00:15:05,750 And here we are, an instance of cheer for us, it is Dubai, the next one is to interrupt in a bit, 236 00:15:05,750 --> 00:15:06,010 right? 237 00:15:06,110 --> 00:15:10,740 This is also you need to act to enable the to here. 238 00:15:11,000 --> 00:15:15,110 Both of this will be working together to close our switch to right. 239 00:15:15,800 --> 00:15:18,710 This required first and instant structure and then. 240 00:15:20,780 --> 00:15:25,460 Instance EPCR and then the mosque, right, so mosque will be the mosque for China. 241 00:15:25,580 --> 00:15:28,610 And so if you go to the tribal fight. 242 00:15:28,640 --> 00:15:33,590 OK, so usually the hardware related information, if you do not find any mosque over here. 243 00:15:34,280 --> 00:15:36,860 So mosque are usually at the top of my trailer. 244 00:15:37,280 --> 00:15:39,350 And here we do not have any mosque, right? 245 00:15:39,350 --> 00:15:42,200 So you go to Dubai and the school réglage, right? 246 00:15:42,500 --> 00:15:49,850 So here you'll be finding all the information which is not mentioned over here, right in the driver 247 00:15:49,850 --> 00:15:50,110 file. 248 00:15:50,120 --> 00:15:57,770 So if you go to the GPA, you underscore L Dot H so you could find the mosque related information. 249 00:15:57,770 --> 00:15:59,030 Do getting to work here right? 250 00:15:59,030 --> 00:16:04,040 So we want to have a chain, Elon Musk, because we are just utilizing the chain L1, right? 251 00:16:04,040 --> 00:16:07,860 So we will be copying this and then we will be adding a door here. 252 00:16:07,900 --> 00:16:08,140 Right. 253 00:16:08,150 --> 00:16:09,200 So this complete the code. 254 00:16:09,440 --> 00:16:13,040 Now what this does is this will automatically close this switch. 255 00:16:13,040 --> 00:16:17,150 Right now, we are ready to send the intro from peripheral to AI in DC, right? 256 00:16:18,260 --> 00:16:19,370 The last step, right? 257 00:16:19,640 --> 00:16:22,820 The last step is to start an operation off and interrupt. 258 00:16:22,850 --> 00:16:27,650 Now we are planning to sense an interest from the hardware itself. 259 00:16:27,650 --> 00:16:27,800 Simple. 260 00:16:27,950 --> 00:16:30,770 So the mode in which we will be operating is really more great. 261 00:16:30,770 --> 00:16:37,550 So we go to an exciting DC and then you have this stock great and this is operating to more rate. 262 00:16:37,550 --> 00:16:40,340 So either it could be the simulation mode, OK? 263 00:16:40,370 --> 00:16:45,980 For that, you'll need to add in simulation mode, or it could be in real more rate that allow us to 264 00:16:45,980 --> 00:16:54,470 work within hardware related interest rate higher when you are utilizing it to sense the enter from 265 00:16:54,470 --> 00:16:55,760 an actual hardware, right? 266 00:16:55,770 --> 00:16:58,460 So we go ahead, we call this OK. 267 00:17:00,190 --> 00:17:06,460 This required first argument as an instance structure, so I in D.C. and then whether you are operating 268 00:17:06,460 --> 00:17:12,600 in a simulation mode or whether you are operating in an hardware mode, right? 269 00:17:12,610 --> 00:17:17,170 So we'll just be calling this because we want to operate in a real moderate. 270 00:17:18,730 --> 00:17:27,180 So this completes all the configuration and initialization that you need to do with the interrupt controller, 271 00:17:27,190 --> 00:17:27,490 right? 272 00:17:28,210 --> 00:17:31,150 So just to distinguish between the different thing that we do. 273 00:17:31,240 --> 00:17:36,400 So this will initialize and enable. 274 00:17:37,680 --> 00:17:51,810 Exception handler, right, there's a representative step one, then specify unique IED or unique. 275 00:17:52,740 --> 00:17:55,620 This could be just specifying trip type. 276 00:17:57,390 --> 00:17:58,850 Interpolate OK. 277 00:17:59,550 --> 00:18:04,200 And then you also need to specify the handler for it, right? 278 00:18:04,500 --> 00:18:10,980 And this is done by the unique idea that you get for an interest in an experimental advantage rate, 279 00:18:11,370 --> 00:18:18,720 then this representing closing switch one rate. 280 00:18:19,850 --> 00:18:26,360 And then this represent losing switch to. 281 00:18:27,930 --> 00:18:29,310 And the last step is start. 282 00:18:30,710 --> 00:18:31,970 Operation in. 283 00:18:33,730 --> 00:18:34,180 Really? 284 00:18:34,510 --> 00:18:34,840 Right? 285 00:18:35,350 --> 00:18:40,780 So these are the series of steps that you need to perform now, in some cases, it may be possible that 286 00:18:40,780 --> 00:18:43,210 you do not have this switch available. 287 00:18:44,640 --> 00:18:47,640 In that case, you could simply skip it, right? 288 00:18:49,490 --> 00:18:52,360 The last spending step is to declare that UPI. 289 00:18:52,910 --> 00:18:53,210 Right. 290 00:18:53,250 --> 00:18:58,820 So what are we going to do is we will be forced disabling and intervention as we reach to handle. 291 00:18:59,120 --> 00:19:01,520 OK, and then we process the interest. 292 00:19:01,790 --> 00:19:07,070 And finally, we enable back an interest rate, so we go ahead first, acknowledge an interest. 293 00:19:07,340 --> 00:19:13,010 So if you go to a 90TSI, so we have an API to acknowledge an interest rate, so we go ahead. 294 00:19:13,950 --> 00:19:15,090 We call this EPA. 295 00:19:16,130 --> 00:19:24,140 First argument is an interrupt handler, and the next one is an unique IED that we get, right, so 296 00:19:24,140 --> 00:19:26,720 that is an unique IED that we have over here. 297 00:19:26,720 --> 00:19:29,420 So we'll just be copying this, adding it over here. 298 00:19:29,480 --> 00:19:29,690 Right. 299 00:19:29,690 --> 00:19:40,310 So once we acknowledge and now we go to the next episode or take a look there, we have an API to disable 300 00:19:40,310 --> 00:19:41,090 and integrate. 301 00:19:41,100 --> 00:19:45,230 So that is what we're going to do here to disable and interrupt. 302 00:19:46,620 --> 00:19:52,800 OK, this required again the Dubai idea and the channel must state, so we'll just be copying this. 303 00:19:53,660 --> 00:19:55,180 We will be adding a door here. 304 00:19:55,470 --> 00:19:55,760 Right? 305 00:19:56,030 --> 00:20:01,910 But once you disable and interrupt, the next step is to serve, and that is what you want to do with 306 00:20:01,910 --> 00:20:02,600 an interest rate. 307 00:20:02,600 --> 00:20:07,310 In this case, we want to send the value that we read on to a console. 308 00:20:07,350 --> 00:20:10,860 OK, so to do that, we just need to call the printer. 309 00:20:12,780 --> 00:20:15,350 Hear what we were going to add is in trouble. 310 00:20:16,620 --> 00:20:17,040 OK. 311 00:20:18,480 --> 00:20:18,810 OK. 312 00:20:19,170 --> 00:20:22,530 And we going to also mention Value Ray. 313 00:20:22,710 --> 00:20:23,070 OK. 314 00:20:23,550 --> 00:20:27,560 But Sidoti again, do not forget to add a new line director. 315 00:20:27,850 --> 00:20:32,160 So, ladies, first to the value of the switch. 316 00:20:32,160 --> 00:20:33,800 OK, in utero, you do. 317 00:20:33,810 --> 00:20:36,180 So this will be switch red. 318 00:20:38,040 --> 00:20:38,400 OK. 319 00:20:38,940 --> 00:20:43,800 And to read the value that we have on a switch, we have a discreet reading period, so we'll just be 320 00:20:43,800 --> 00:20:49,020 calling this, and the China number for us is what rate we will be adding this. 321 00:20:49,080 --> 00:20:52,630 The instant structure for us is GPIO China. 322 00:20:52,630 --> 00:20:53,730 The number will do like rate. 323 00:20:53,730 --> 00:20:55,280 So we are reading the value of switch. 324 00:20:55,290 --> 00:21:00,000 We already set up the direction when we initialize our GPI or badassery right here, you could clearly 325 00:21:00,270 --> 00:21:00,870 remember. 326 00:21:01,170 --> 00:21:05,330 And then we will be printing the value of it, right? 327 00:21:05,340 --> 00:21:09,510 So this is the process that we need to do when we have an interest. 328 00:21:10,650 --> 00:21:17,700 Now we'll see whether we have an EPA to clear the pending enterprise, so here we have an EPA. 329 00:21:19,330 --> 00:21:24,130 This will clear up the spending, and so we'll just be calling it over here, OK? 330 00:21:24,550 --> 00:21:30,640 And there's again required the same to argument that we have for an interpreter, so we collided over 331 00:21:30,640 --> 00:21:37,450 here and then the last step is to enable and interrupt so that we could receive the new request. 332 00:21:37,690 --> 00:21:39,850 Then user changed the switch, right? 333 00:21:39,850 --> 00:21:41,440 So we'll just be calling this. 334 00:21:43,340 --> 00:21:43,670 OK. 335 00:21:43,910 --> 00:21:45,890 Again, this required this to argue. 336 00:21:47,410 --> 00:21:52,080 OK, so once this is done, this complete the process, right, so we need to first acknowledge an injury, 337 00:21:52,420 --> 00:21:59,220 disable and injured so that we do not get the new request until we solve the current danger request. 338 00:21:59,860 --> 00:22:03,040 Then we read the value from a switch, OK? 339 00:22:03,370 --> 00:22:05,560 We are sending that value on to a console. 340 00:22:05,620 --> 00:22:10,260 We are clearing any pending request and then we are enabling back our interest rate. 341 00:22:10,270 --> 00:22:12,580 So this is what we're going to do in an independent. 342 00:22:12,890 --> 00:22:13,660 But this is done. 343 00:22:13,660 --> 00:22:17,210 We just need to call an interrupt handler in our main application, right? 344 00:22:17,210 --> 00:22:19,750 So we already called GPI on it. 345 00:22:19,820 --> 00:22:20,830 Now we are calling an in. 346 00:22:21,610 --> 00:22:24,310 And with an intro, we just need to perform a reading. 347 00:22:24,910 --> 00:22:28,810 OK, so that user will add an intro and then that will be serving us right? 348 00:22:28,810 --> 00:22:30,250 So we do not need to do anything. 349 00:22:30,250 --> 00:22:31,510 We'll just be waiting here. 350 00:22:31,840 --> 00:22:37,280 So while one and then as soon as user genes dusted off a search, we will be getting an interrupt and 351 00:22:37,280 --> 00:22:39,580 that will be sold by our interpreter, right? 352 00:22:39,880 --> 00:22:45,760 So this completes an entire knew what we were going to add when you are working with an interest rate. 353 00:22:46,000 --> 00:22:49,210 So let us proceed to build up our entire application project. 354 00:22:51,090 --> 00:22:53,100 To one to build a successful. 355 00:22:54,930 --> 00:22:58,910 We will select an application project debug at launch on hardware. 356 00:22:59,720 --> 00:23:05,240 OK, so this will switch our perspective from design to debug and automatically program our FPGA. 357 00:23:05,240 --> 00:23:11,350 We go to a dystopia where we will be selecting the Column six and the border, which is nine six zero 358 00:23:11,360 --> 00:23:11,830 six, right? 359 00:23:11,870 --> 00:23:16,330 The only thing that we're going to need is to click on a resume button, right? 360 00:23:16,340 --> 00:23:21,970 So once you do that, you'll be finding that GPIO initialization is successful in D.C. and it is also 361 00:23:21,980 --> 00:23:22,540 successful. 362 00:23:22,540 --> 00:23:24,240 LightSail test is also successful. 363 00:23:24,240 --> 00:23:29,830 You know, what we're going to do is will be changing the state of the switch, right, too. 364 00:23:31,490 --> 00:23:35,750 And as soon as you could see as I change the value of a switch. 365 00:23:36,080 --> 00:23:38,330 So let me just go ahead, right? 366 00:23:38,330 --> 00:23:43,730 So now what we're going to do is we will be changing the state of an Elizabeth switch, right? 367 00:23:43,730 --> 00:23:49,010 So if I make a little switch one, you could see that the value really lives like if I change the next 368 00:23:49,010 --> 00:23:50,110 LSP switch. 369 00:23:50,120 --> 00:23:56,180 So we'll be finding the value three if I change next one, the value seven, if I change next one, 370 00:23:56,180 --> 00:24:00,590 the value is fifteen thirty one, sixty three and so on and so forth. 371 00:24:00,680 --> 00:24:00,920 Right. 372 00:24:01,220 --> 00:24:06,520 So you could clearly see be able to sense and enter and send the value on to a console.
