1 00:00:00,060 --> 00:00:01,950 So let us start writing a logic, right? 2 00:00:01,950 --> 00:00:08,490 So if you remember, this step is to add an exception handler for ICP, right? 3 00:00:08,490 --> 00:00:15,040 So by default, the internal exception handler for our CPU is disabled and it is also an initialized 4 00:00:15,040 --> 00:00:15,240 rate. 5 00:00:15,240 --> 00:00:17,680 So we need to also enable it. 6 00:00:17,700 --> 00:00:19,600 We also need to initialize it, right? 7 00:00:19,620 --> 00:00:26,310 So let's just perform this process, and we already know that all the API Zach will be helping out to 8 00:00:26,310 --> 00:00:28,440 handle this situation and are present in it. 9 00:00:28,800 --> 00:00:29,760 The exception? 10 00:00:29,770 --> 00:00:31,370 Not etch haggis. 11 00:00:31,620 --> 00:00:31,830 Right? 12 00:00:32,190 --> 00:00:34,740 So we will be adding the exception. 13 00:00:35,250 --> 00:00:36,080 This is unheard of. 14 00:00:36,540 --> 00:00:37,470 OK, great. 15 00:00:37,470 --> 00:00:40,710 You will be finding various APIs that will be helping us, right? 16 00:00:41,220 --> 00:00:43,650 So first, let's just in the die. 17 00:00:44,640 --> 00:00:50,580 Exception handler, OK, so to do that, we must be having an EPA, so here you could see we have a 18 00:00:50,580 --> 00:00:53,580 delay exception to it, do not return anything. 19 00:00:53,580 --> 00:00:56,460 And in fact, they do not accept anything, Rachel. 20 00:00:56,490 --> 00:01:02,880 Both argument as well as written is white, so it will go ahead to our allowed and this will be adding 21 00:01:02,880 --> 00:01:05,510 in MGC because this is related to it, right? 22 00:01:05,730 --> 00:01:09,750 OK, so both initialization and assignment two are exception. 23 00:01:09,750 --> 00:01:11,820 Handler will be done. 24 00:01:12,720 --> 00:01:13,480 Here, right? 25 00:01:13,500 --> 00:01:17,520 So we'll proceed with first exception and exemption, OK? 26 00:01:17,880 --> 00:01:24,660 The next step is if you remember after you initialize an exception handler, then you need to identify 27 00:01:24,660 --> 00:01:28,250 an interest rate to the type of an interest that we're adding. 28 00:01:28,470 --> 00:01:30,420 And along with that, which is the. 29 00:01:31,440 --> 00:01:32,790 In Handler for us. 30 00:01:33,040 --> 00:01:35,970 So we'll go now to do that. 31 00:01:36,950 --> 00:01:43,370 With the exception, we have a register hanging here, we will be registering the type of fight. 32 00:01:44,630 --> 00:01:45,020 OK. 33 00:01:45,290 --> 00:01:49,070 The tape of an interest that we are a blank and then the look for it, right? 34 00:01:50,310 --> 00:01:53,760 Who will just be copying this will be adding it to here. 35 00:01:54,120 --> 00:01:54,540 OK? 36 00:01:54,570 --> 00:02:01,440 The first argument that did have is the type of an interest rate, so the exception might be so if you 37 00:02:01,440 --> 00:02:04,980 just go above, you'll be finding an exception. 38 00:02:04,980 --> 00:02:05,830 It's OK. 39 00:02:05,850 --> 00:02:07,680 So we are utilizing an IQ. 40 00:02:07,950 --> 00:02:13,160 So, Jill exception, I do before I work with this one, so we'll just copy and paste you. 41 00:02:13,660 --> 00:02:19,240 So this represents the type of an interest we do have and other ideas for different type of an interest. 42 00:02:19,240 --> 00:02:24,120 So we have an if IQ, the software in Japan, you find you said and so on and so forth. 43 00:02:24,190 --> 00:02:24,410 Great. 44 00:02:24,420 --> 00:02:26,750 So type of job that we are utilizing. 45 00:02:27,180 --> 00:02:36,060 And I ask you the next arguing that Mr. Handler have is the exceptional rate. 46 00:02:36,070 --> 00:02:42,170 So here I meet Master Controller is the general in control rate. 47 00:02:42,180 --> 00:02:45,700 So that will serve as an intro handler for us. 48 00:02:45,700 --> 00:02:47,400 So we'll just be typecasting it. 49 00:02:47,700 --> 00:02:53,080 And if you go to a geek that will be finding an interest handler. 50 00:02:53,520 --> 00:02:56,580 So this will be the master handler for us. 51 00:02:56,730 --> 00:02:59,100 So we'll just be specifying Peter Waheed. 52 00:02:59,310 --> 00:02:59,640 OK. 53 00:03:00,210 --> 00:03:06,150 And then we need to specify and GI scenes say so that is CIC. 54 00:03:06,570 --> 00:03:06,860 Right? 55 00:03:07,170 --> 00:03:10,050 So these are the three things that we need to specify. 56 00:03:10,050 --> 00:03:16,230 And once we do this now, this will remain common for almost all the type of an internet will be utilizing 57 00:03:16,530 --> 00:03:17,250 all fired. 58 00:03:17,940 --> 00:03:22,090 So we'll always be working around within GI syndrome handler. 59 00:03:22,140 --> 00:03:26,370 The insurgents will always be engaged and I bet you will be right. 60 00:03:26,520 --> 00:03:26,760 Right. 61 00:03:26,770 --> 00:03:27,780 So we initialize it. 62 00:03:27,780 --> 00:03:29,520 We register the name of an interest. 63 00:03:29,520 --> 00:03:30,880 The next step is to enable it. 64 00:03:31,660 --> 00:03:34,260 If you just go, add to the delay exception. 65 00:03:34,770 --> 00:03:40,390 So there you find a function to enable AI exception. 66 00:03:40,620 --> 00:03:42,170 So that will be at first. 67 00:03:42,540 --> 00:03:42,860 OK. 68 00:03:43,620 --> 00:03:47,010 And just be adding to it here, and it doesn't require any OK. 69 00:03:47,190 --> 00:03:51,540 So this complete all the process that we need to perform it and select option. 70 00:03:51,540 --> 00:03:58,170 Heading to the Steps two is complete, so the internal exception handler for our CPU is both disabled 71 00:03:58,170 --> 00:03:59,580 as well as an initialize. 72 00:03:59,580 --> 00:04:05,660 So we need to initialize it and we also need to enable it by assigning the correct input, right? 73 00:04:05,670 --> 00:04:07,550 So this is the step process. 74 00:04:07,560 --> 00:04:08,160 First, we. 75 00:04:08,910 --> 00:04:12,780 I had an initialization for our audits of Candler exception handler. 76 00:04:13,120 --> 00:04:17,130 Then we identified the type of an interest by utilizing register handler. 77 00:04:17,140 --> 00:04:20,740 Dare we specify the type of an interest and a range of handler? 78 00:04:20,870 --> 00:04:28,540 OK, and last thing is to enable and write to this completed step to the last step is be to work around 79 00:04:28,540 --> 00:04:30,130 retention and drop control. 80 00:04:30,210 --> 00:04:33,520 OK, so we need to specify the in-joke handler. 81 00:04:33,520 --> 00:04:35,510 We need to enable and interrupt. 82 00:04:35,530 --> 00:04:35,890 OK. 83 00:04:36,100 --> 00:04:43,720 We also need to enable Line two by default hide in Japan that could not receive an interview input from 84 00:04:43,720 --> 00:04:44,650 any of the preparer. 85 00:04:44,650 --> 00:04:46,450 So we need to enable it to. 86 00:04:46,450 --> 00:04:53,680 The function to enable it will be finding it that a fight, whereas we also need to enable an output 87 00:04:53,680 --> 00:04:55,480 of an intro from very, very large. 88 00:04:56,020 --> 00:05:04,270 So to the function that will be used to enable the output from a very will be found out from the benefit 89 00:05:04,270 --> 00:05:05,710 of specific tribal fights. 90 00:05:05,950 --> 00:05:13,300 So let me just go first, utilize or specify the drop handler, right, who will just declared one function 91 00:05:13,330 --> 00:05:19,330 that can serve as an interrupt handler for us, which Rachel will just be naming this as which i a.i. 92 00:05:19,390 --> 00:05:19,780 OK. 93 00:05:20,050 --> 00:05:24,310 Remember, intercept handlers never written anything, so there will always be an moit. 94 00:05:24,650 --> 00:05:27,710 OK, and here we'll be writing an entire logic. 95 00:05:27,730 --> 00:05:28,100 OK. 96 00:05:28,120 --> 00:05:29,110 As soon as interrupt. 97 00:05:29,380 --> 00:05:31,760 So go ahead to egusi. 98 00:05:31,810 --> 00:05:36,730 Next will be the logic for sure, right? 99 00:05:37,090 --> 00:05:40,760 You can just go to an ex SC. 100 00:05:40,870 --> 00:05:41,660 UGC. 101 00:05:42,340 --> 00:05:45,910 The first thing that we do is to utilize the connect function, right? 102 00:05:45,910 --> 00:05:53,110 So here we specify the entropy handler, and it only that the specific device rates will be recognized 103 00:05:53,110 --> 00:05:54,760 that it is near due date. 104 00:05:54,790 --> 00:05:58,450 Now we may be having a different type interest rate. 105 00:05:58,690 --> 00:06:04,630 So each and just having unique ID, that will be specifying over here and then for that specific ID, 106 00:06:04,790 --> 00:06:06,730 which will be an intra handler, right? 107 00:06:06,730 --> 00:06:09,670 So let's just go ahead and copy this. 108 00:06:10,090 --> 00:06:11,170 They do it here, right? 109 00:06:11,650 --> 00:06:13,930 First argument for it is. 110 00:06:14,900 --> 00:06:20,660 The instance of magazines, and so for us, it is, gee, I see, OK. 111 00:06:21,990 --> 00:06:23,700 The next one is in jeopardy. 112 00:06:23,730 --> 00:06:30,000 So where do you find an interplay, the experimental detection we had or having an intercept on a switch, 113 00:06:30,000 --> 00:06:30,240 right? 114 00:06:30,240 --> 00:06:35,180 So we'll just be copying this in jeopardy and we will be pasting it over here. 115 00:06:35,280 --> 00:06:35,480 Right. 116 00:06:35,500 --> 00:06:40,380 So this will be wearing four different protective for which it is six. 117 00:06:40,380 --> 00:06:42,080 When, OK? 118 00:06:42,240 --> 00:06:45,120 And it may not be seen for the paper. 119 00:06:45,180 --> 00:06:50,370 So you just need to go to the periphery tab in an experimental detector and they will be finding unique 120 00:06:50,370 --> 00:06:51,410 interest rate. 121 00:06:52,460 --> 00:06:57,320 The next eight required and handled it, OK, so this will be an angle which will be called as soon 122 00:06:57,320 --> 00:07:02,280 as we have an inch up, so we'll just be specifying the function that we have added it. 123 00:07:02,290 --> 00:07:03,830 Just such changer, right? 124 00:07:04,670 --> 00:07:12,920 Remember whenever we have the exception handler or any handler do Typekit, so this will remove an unnecessary 125 00:07:12,920 --> 00:07:13,650 one, right? 126 00:07:13,670 --> 00:07:20,220 So once you do this, the last step that is required is then a callback reference. 127 00:07:20,220 --> 00:07:23,900 So here we do not need to specify anything because we do not want to. 128 00:07:25,090 --> 00:07:30,190 Having access to any data when we entered into and into a function. 129 00:07:31,510 --> 00:07:38,840 OK, so this completes step one now will proceed and we will be enabling entropy. 130 00:07:39,100 --> 00:07:46,090 OK, so our general controller will receive an entrapping from the Pay-To-Play, so it is just required 131 00:07:46,390 --> 00:07:52,030 the instant and the interest rate, so we'll just be adding it. 132 00:07:53,530 --> 00:07:56,300 Here we have both the parameters, right? 133 00:07:56,350 --> 00:08:00,420 So we'll just be copying an instant structure and the entire time. 134 00:08:00,630 --> 00:08:00,830 Right. 135 00:08:00,850 --> 00:08:02,230 So this complete the second step. 136 00:08:02,590 --> 00:08:08,410 And in fact, you'll be noticing, we specify and interestingly, we also enable and encrypt. 137 00:08:08,470 --> 00:08:16,480 OK, now this is related to a normal procedure for enabling an intro output from a benefit. 138 00:08:16,480 --> 00:08:22,570 And so to find out the specific function, you need to go to the benefit of a specific driver. 139 00:08:22,710 --> 00:08:25,540 So we have GPIO. 140 00:08:25,960 --> 00:08:26,350 OK? 141 00:08:26,710 --> 00:08:32,140 And here if we just go ahead to find out the functions that we have. 142 00:08:33,240 --> 00:08:39,390 So we have two functions to enable an interest, so first one is a global interest in everything then 143 00:08:39,460 --> 00:08:41,420 and interpreting the right to let it just go. 144 00:08:42,000 --> 00:08:47,730 This required just an instance pointer so porous switches where we have an interest, so we just be 145 00:08:47,730 --> 00:08:50,190 specifying switch as an instant structure. 146 00:08:50,700 --> 00:08:55,060 The second one is to use and interpret and invalidate. 147 00:08:55,110 --> 00:09:00,210 So whenever you have both the function that is enabling of global interest, as well as the benefit 148 00:09:00,210 --> 00:09:01,080 of specific interest. 149 00:09:01,110 --> 00:09:04,710 So you need to add both of them if you only have a very specific interest. 150 00:09:04,720 --> 00:09:06,300 So you just need to add that one, right? 151 00:09:07,620 --> 00:09:15,390 And here we probably need to specify, again, licensed and muscle mass represent which China you have 152 00:09:15,390 --> 00:09:20,790 an interest rate, so usually you'll be finding data related to masking, then had it by itself. 153 00:09:20,790 --> 00:09:23,040 So we'll just be adding an instance. 154 00:09:23,850 --> 00:09:30,330 So if you go to an AA, tribal fights, OK, so let me just go up and see whether we have any data related 155 00:09:30,330 --> 00:09:31,110 to Musk. 156 00:09:31,260 --> 00:09:31,620 OK. 157 00:09:32,040 --> 00:09:36,870 So if you do not find any data related, you must usually underscore L file will also be there. 158 00:09:36,870 --> 00:09:42,990 So if you just see an outline, so here you could see we have an X GPA, a score l. 159 00:09:43,110 --> 00:09:43,470 OK. 160 00:09:44,040 --> 00:09:50,130 So you can just go in there and you could see that you have a mask so you will be on the squirrel or 161 00:09:50,130 --> 00:09:51,240 in the school or hide of it. 162 00:09:51,240 --> 00:09:57,090 OK, so this to the side where you will be finding an extra information related to and so we'll just 163 00:09:57,090 --> 00:10:01,440 be copying China changeable mask because we have an interest on our China, right? 164 00:10:02,100 --> 00:10:05,370 So this complete our step. 165 00:10:05,370 --> 00:10:12,340 See, OK, so this are all the things that we need to do to use interest right to be initialized. 166 00:10:12,340 --> 00:10:14,820 An exception handler, we enable an exception handler. 167 00:10:14,820 --> 00:10:23,190 We specify the ancient handler, OK, and then we enable both the interrupt input for Agassi, as well 168 00:10:23,190 --> 00:10:29,040 as an enter output from up 80 percent right now, will be writing a code for and switch. 169 00:10:29,070 --> 00:10:33,660 So whenever you are writing an independent as soon as you enter into an hagler's, the first thing that 170 00:10:33,660 --> 00:10:37,860 you do is to disable an intra radiologic clear and interrupt. 171 00:10:37,860 --> 00:10:38,940 And then again, you never do. 172 00:10:39,180 --> 00:10:42,930 So this process will also remain seem for almost all the paper. 173 00:10:43,020 --> 00:10:45,270 So if you go to a GPO again. 174 00:10:45,450 --> 00:10:45,750 Right? 175 00:10:46,110 --> 00:10:51,080 So first thing that we do is to disable and interpret how can this require to argument? 176 00:10:51,090 --> 00:10:54,060 But one is our GPO instance. 177 00:10:54,060 --> 00:10:56,130 We just switch and the channel was great. 178 00:10:56,150 --> 00:11:00,690 So Channel Mask will be seen as we used in it. 179 00:11:01,460 --> 00:11:04,020 It we'll just be adding it here. 180 00:11:05,070 --> 00:11:06,950 Then we will be writing a logic. 181 00:11:06,960 --> 00:11:12,510 So what are we going to do here is we will be reading the reader from a switch, storing it somewhere, 182 00:11:12,780 --> 00:11:14,260 sending it to any LCD. 183 00:11:14,280 --> 00:11:15,830 That is what we're going to write. 184 00:11:16,650 --> 00:11:22,830 So for reading a reader, we have discrete read API, right? 185 00:11:22,830 --> 00:11:24,570 And this basically a new 32. 186 00:11:25,200 --> 00:11:28,530 So it required again an instance pointer and China number. 187 00:11:28,540 --> 00:11:33,230 So we only have a single channel to let it just declare you 32, because that is the detail. 188 00:11:33,250 --> 00:11:42,690 What are discrete read, read and this will be switch data and this will be connecting to discretely. 189 00:11:42,960 --> 00:11:48,390 So first, we need to specify the GPO instance, which is which. 190 00:11:48,810 --> 00:11:49,920 Then we have a channel to. 191 00:11:49,920 --> 00:11:51,690 We are only working with a single channel. 192 00:11:51,720 --> 00:11:53,040 We just need to add one, right? 193 00:11:53,050 --> 00:11:53,910 So this is the logic. 194 00:11:54,270 --> 00:11:57,210 We'll also be sending this data on to work on. 195 00:11:57,220 --> 00:12:01,650 So great does is just for a deeper purpose, so switch. 196 00:12:03,230 --> 00:12:06,730 OK, so we have a time switch, right? 197 00:12:07,250 --> 00:12:13,580 And we also want to write this down to an elderly, so to do that, we have a discreet rate where we 198 00:12:13,580 --> 00:12:17,330 could write go down to a bathing suit. 199 00:12:17,330 --> 00:12:20,690 Aquarians just point to changing Amber and Musk, right? 200 00:12:21,470 --> 00:12:24,830 So if you just go ahead, it requires basically a data. 201 00:12:25,250 --> 00:12:27,290 It is an instance going to change the number. 202 00:12:27,290 --> 00:12:32,900 And so we'll go over here, OK, here and instances. 203 00:12:34,010 --> 00:12:34,400 OK. 204 00:12:35,000 --> 00:12:42,020 The China-Laos one and then the data that we want to send it's switch right now here. 205 00:12:42,020 --> 00:12:48,090 What we are doing is we are considering switch as an input and it is an option, but we haven't specified 206 00:12:48,260 --> 00:12:49,220 action anyway, right? 207 00:12:49,730 --> 00:12:53,060 In the mean program, you are just calling and init function. 208 00:12:53,090 --> 00:12:55,400 Again, we haven't specified that addiction. 209 00:12:55,400 --> 00:12:59,360 So when we initialized UPI itself, we could specify a direction. 210 00:12:59,370 --> 00:13:01,820 So let me just try to add a direction over here. 211 00:13:02,180 --> 00:13:07,910 OK, so to set the direction, we have this API where we need to specify an instance pointer in number 212 00:13:07,910 --> 00:13:10,060 and direction masquerade. 213 00:13:10,080 --> 00:13:16,400 So we'll just be going ahead with this, whereas this is in postures switch, right? 214 00:13:16,400 --> 00:13:21,590 So when we consider Switch, we have a Channel one and we have a forward switch or get to consider any 215 00:13:21,590 --> 00:13:23,360 of the food as an input port. 216 00:13:23,360 --> 00:13:32,450 If you analyze the function, we just need to apply one to bit set to zero output and set to another 217 00:13:32,450 --> 00:13:32,770 input. 218 00:13:33,020 --> 00:13:35,540 So we have a food switch, so will just be. 219 00:13:36,640 --> 00:13:43,040 Adding apparatus to this will consider the list before bed to be one, and that will basically make 220 00:13:43,040 --> 00:13:45,980 the switch as an impact, right? 221 00:13:46,390 --> 00:13:53,740 Similar thing we do need to do with an elderly also, but for an elderly, we need to set it as an output 222 00:13:53,770 --> 00:13:56,470 so far and setting an output what we just need to apply. 223 00:13:56,950 --> 00:13:57,320 See? 224 00:13:57,550 --> 00:13:57,810 Right. 225 00:13:58,810 --> 00:14:03,310 So here we are, setting up our addiction when we complete initialization of UPI. 226 00:14:03,350 --> 00:14:08,000 Right now, we are ready to write and read the data from the switch, right? 227 00:14:09,120 --> 00:14:10,140 Now will proceed. 228 00:14:10,410 --> 00:14:16,920 And this is an algorithm that we want to perform when we reached and in Japan to disable and ensure 229 00:14:17,730 --> 00:14:19,860 we perform a respectable algorithm. 230 00:14:19,890 --> 00:14:24,930 Now we'll proceed for clearing up any interest that we have in the queue. 231 00:14:25,530 --> 00:14:29,680 OK, here the two things that we need to add is this. 232 00:14:30,690 --> 00:14:40,330 And the last thing that we need to do is before we exit and handler is to enable into a right. 233 00:14:40,920 --> 00:14:46,350 These that some of the steps that we need to perform while working with them. 234 00:14:47,670 --> 00:14:48,330 Interesting. 235 00:14:48,810 --> 00:14:55,920 Right, so let me just go there and now try to perform an execution of this, right, so remember the 236 00:14:55,920 --> 00:15:00,730 process, the first step is to initialize medical and take. 237 00:15:01,170 --> 00:15:04,860 The second step is to add an exception, Hala. 238 00:15:04,890 --> 00:15:11,490 So we need to both initialize as well as a saying and exceptionnelle them to work around with each handle 239 00:15:12,330 --> 00:15:12,630 right? 240 00:15:13,610 --> 00:15:15,020 We'll just go and see you. 241 00:15:15,560 --> 00:15:17,580 OK, will program refugee? 242 00:15:19,080 --> 00:15:21,870 We are already going to do dollars to get him in the lower here. 243 00:15:21,960 --> 00:15:22,320 OK. 244 00:15:22,740 --> 00:15:25,810 And then we will be going ahead with. 245 00:15:26,790 --> 00:15:32,160 Execution of my application right to it, just getting a new line character who are here, let they 246 00:15:32,160 --> 00:15:34,170 just proceed and try to execute. 247 00:15:34,650 --> 00:15:41,850 So if everything goes fine and they change the state of Slate, which will be able to get the notification 248 00:15:41,850 --> 00:15:47,400 on Arkansas, right, so I try to change the MSP switch to one right. 249 00:15:47,410 --> 00:15:54,690 So this will make our output to be equal to eight because we now have for at least two MSP switches 250 00:15:54,710 --> 00:15:55,800 change to one. 251 00:15:56,040 --> 00:15:58,050 So we have one zero zero zero. 252 00:15:58,060 --> 00:16:03,180 So that is equivalent to eight if I turn on the next switch, so we'll be getting to it. 253 00:16:04,400 --> 00:16:04,650 Right. 254 00:16:05,120 --> 00:16:10,750 If I turn on the next, which I'll be getting foggy and the last one, it's 50, right? 255 00:16:11,120 --> 00:16:17,180 You could clearly see as I teach the seat of a which we are getting an inch up and then we are painting 256 00:16:17,180 --> 00:16:19,670 the values onto a console line. 257 00:16:19,970 --> 00:16:22,070 We are also seeing the changes on it.
