1 00:00:00,150 --> 00:00:07,140 We successfully complete the generation of a team, and what we want to do is we will be exporting the 2 00:00:07,530 --> 00:00:12,170 hardware into an SDK, so we'll just go to file export export. 3 00:00:12,420 --> 00:00:15,900 They will also be including of the extreme right. 4 00:00:16,290 --> 00:00:20,130 Once we do this, we will go ahead and will launch an SDK right away. 5 00:00:20,130 --> 00:00:23,070 I will start building our see application. 6 00:00:25,400 --> 00:00:31,220 OK, so we already have our hardware packed on Spec. Over here, which includes all the 1980 files, 7 00:00:31,220 --> 00:00:34,400 such as initializing the processing system a bit fine. 8 00:00:34,480 --> 00:00:40,430 OK, now we'll go ahead and will utilize the hellotel template that we have at this rate. 9 00:00:40,430 --> 00:00:43,280 So we'll just need this as GPL e-mail. 10 00:00:43,700 --> 00:00:47,540 OK, and then we'll be selecting in Hallowell dump, right? 11 00:00:48,800 --> 00:00:55,880 Now here, once we create a fight, a weakened law which try where we need to utilize foreign GPI, 12 00:00:55,970 --> 00:00:58,120 so we'll just go for a GPIO. 13 00:00:58,520 --> 00:01:00,290 Here you can see the driver. 14 00:01:00,650 --> 00:01:03,780 The recommended driver for us is GPI is right. 15 00:01:03,800 --> 00:01:08,720 So we'll just proceed, go to Helloworld or see OK, which is, I mean, fight. 16 00:01:09,080 --> 00:01:13,970 And then here we start adding RC application rate. 17 00:01:14,300 --> 00:01:19,080 First thing is, we will be including some of the mandatory drivers. 18 00:01:19,080 --> 00:01:26,030 So we have X will be estratégia, which will help us to work around with the periphery. 19 00:01:26,330 --> 00:01:32,450 OK, the next one that we're required is experimental stage, so that will provide us all the data related 20 00:01:32,450 --> 00:01:35,590 to the hardware right now. 21 00:01:35,600 --> 00:01:37,640 If you just explore GPI, OK? 22 00:01:37,910 --> 00:01:42,980 So what we did in a previous case, we again need to do to initialize the peripheral. 23 00:01:43,430 --> 00:01:44,730 OK, we require to structure. 24 00:01:44,750 --> 00:01:46,280 One is the config structure. 25 00:01:46,850 --> 00:01:50,020 OK, that will be declaring as a pointer. 26 00:01:50,030 --> 00:01:54,960 So they just need this as GPIO config, OK? 27 00:01:54,960 --> 00:01:59,060 And we required the structure, which will hold an instance. 28 00:01:59,060 --> 00:02:01,970 The director will just be calling this structure. 29 00:02:02,000 --> 00:02:05,640 We're here and we will be naming it as GPI, right? 30 00:02:05,680 --> 00:02:07,880 So this will be a simple structure. 31 00:02:07,880 --> 00:02:09,230 It won't be a point, right? 32 00:02:09,710 --> 00:02:12,770 Then we declared one function that will be. 33 00:02:14,150 --> 00:02:21,530 Initializing are petrified, right, so let me just go ahead and try to add the initialization. 34 00:02:22,100 --> 00:02:27,410 So first we'll look for the device aile, and for that we do have information to the function that we'll 35 00:02:27,410 --> 00:02:32,080 be utilizing is GPIO look configure and this returns the config structure. 36 00:02:32,090 --> 00:02:35,900 OK, so we just need to buy this argument and the device idea, right? 37 00:02:35,990 --> 00:02:43,690 So for the config structure is GPIO config, OK, and this will be attaching to the lookup config function. 38 00:02:43,700 --> 00:02:49,070 And here we need to pass the device A.D. So to get the device to you just need to go to experimentar 39 00:02:49,070 --> 00:02:50,640 to attach file look for. 40 00:02:51,980 --> 00:02:59,030 OK, and then you get this macro, OK, which you just need to apply here, right? 41 00:02:59,570 --> 00:03:00,540 This is the first step. 42 00:03:00,560 --> 00:03:07,350 The next step will be to use the initialize to initialize the Palestinian, right. 43 00:03:07,370 --> 00:03:10,960 So if we go to stupid old dart, yes. 44 00:03:10,960 --> 00:03:18,680 So here you have CFD initialization, which again requires three arguments so instance structure, config 45 00:03:18,680 --> 00:03:20,150 structure and interest rate. 46 00:03:20,180 --> 00:03:23,090 So again, address could be found out from experimentar. 47 00:03:23,090 --> 00:03:23,750 Don't actually. 48 00:03:24,980 --> 00:03:34,640 First argument is the ancient structure, which is GPIO, then conflict structure, so you can think, 49 00:03:35,540 --> 00:03:36,920 OK in the last one is a base. 50 00:03:37,230 --> 00:03:42,350 So if you go to experimental door that you could find out, double etc. so you just need to pass it. 51 00:03:42,620 --> 00:03:46,400 And that's basically written whether initialization is successful or not. 52 00:03:46,430 --> 00:03:46,620 Right. 53 00:03:46,670 --> 00:03:54,860 So to check whether initialization is successful or not, they'll just declare in status and then whatever 54 00:03:54,860 --> 00:03:58,850 this function rate, and we'll just be storing in this variable save. 55 00:04:00,950 --> 00:04:03,730 Does 60 success? 56 00:04:03,770 --> 00:04:12,410 OK, we could see that we successfully initialize the device rate so the cell brain death, and then 57 00:04:12,410 --> 00:04:14,660 we could just mention device in it. 58 00:04:16,670 --> 00:04:17,780 Successful rate. 59 00:04:19,550 --> 00:04:28,340 Else is this we could just be mentioning that we failed to initialize our basic rate will again be adding 60 00:04:28,350 --> 00:04:32,580 till primitive device initialization free rate. 61 00:04:32,930 --> 00:04:36,560 So this is what we are going to do in any next function. 62 00:04:36,830 --> 00:04:39,140 Now, after the initial are you what? 63 00:04:39,240 --> 00:04:39,610 Right? 64 00:04:39,620 --> 00:04:42,680 So we will just be calling this innate function. 65 00:04:42,680 --> 00:04:45,830 So this will automatically initialize our base very late. 66 00:04:45,830 --> 00:04:53,870 And then we start with a message that we are starting our test rate so that they just go ahead and mention 67 00:04:53,870 --> 00:05:00,620 we are starting the or e-mail list right now. 68 00:05:00,620 --> 00:05:01,940 Here we relied on logic. 69 00:05:02,120 --> 00:05:05,330 So the first thing that we do is to set the direction for report. 70 00:05:05,340 --> 00:05:12,300 So if you go ahead to and we will be predominantly working on a into do not work with this bank API 71 00:05:12,320 --> 00:05:18,650 to instead work on a ping API, Rachel, we have the same direction, OK, which required an instance 72 00:05:18,650 --> 00:05:20,900 structure, pin number and the direction. 73 00:05:21,800 --> 00:05:23,930 OK, well, just go ahead. 74 00:05:24,890 --> 00:05:28,550 And this way required to specify for each pin, right? 75 00:05:28,550 --> 00:05:31,200 So for us, an incident structure is GPIO. 76 00:05:31,960 --> 00:05:38,150 OK, the next day is the pin number, so first pin will be fifty four and we already know that we connected 77 00:05:38,750 --> 00:05:46,740 switches at the ellipse before because the GPI will create so Fifty-Four will be a switch. 78 00:05:46,760 --> 00:05:49,910 So here we need to set the direction to be input, right? 79 00:05:49,920 --> 00:05:52,670 And we already know if you just explore this function. 80 00:05:52,940 --> 00:05:56,570 So for setting any of the pain as an input, we just need to apply. 81 00:05:56,570 --> 00:05:59,240 Zero rate will apply zero here. 82 00:06:00,440 --> 00:06:07,760 So when we consider planning, but what we do not need to utilize the output enablement rate, so this 83 00:06:07,760 --> 00:06:09,860 will be doing for all the input that we have. 84 00:06:10,490 --> 00:06:17,870 So here we said pin number 54, 55 56 57, which represent the database, which is at an input trade. 85 00:06:18,080 --> 00:06:23,410 The next one will be doing the same thing for our reality now when we considered an elderly. 86 00:06:23,480 --> 00:06:29,000 So we need to do two things that is first, we need to set the direction as an output and then we also 87 00:06:29,000 --> 00:06:30,650 need to enable an output rate. 88 00:06:31,010 --> 00:06:36,530 So the pin, the EMI number there, we will be having our it. 89 00:06:36,800 --> 00:06:43,340 Fifty eight, fifty nine, then sixty and sixty one night to set this as an output. 90 00:06:43,550 --> 00:06:46,280 We need to apply one one one nine. 91 00:06:46,280 --> 00:06:46,820 What right? 92 00:06:47,600 --> 00:06:51,980 And then we need to do one more thing that is we need to enable and operate. 93 00:06:51,980 --> 00:06:53,510 So we have a function to do that. 94 00:06:54,140 --> 00:06:58,370 So set output enable PIN and we just need to apply one over here. 95 00:06:58,400 --> 00:07:02,870 Right again, we need to pass an instance structure and a pin number. 96 00:07:02,870 --> 00:07:04,190 So let me just square. 97 00:07:04,700 --> 00:07:07,940 First is an instance name, OK, which is GPIO. 98 00:07:08,240 --> 00:07:10,490 PIN number is fifty eight, OK? 99 00:07:10,490 --> 00:07:17,240 And then we just need to apply one right this way required to do for all the bins where we have our 100 00:07:17,240 --> 00:07:18,140 l'église right. 101 00:07:18,320 --> 00:07:24,500 So we have our digits at 58, 59, 60 and 61, right? 102 00:07:24,500 --> 00:07:30,980 So we said the direction for all the points where we have our elderly as well as we also enable an output 103 00:07:30,980 --> 00:07:31,220 rate. 104 00:07:31,220 --> 00:07:38,300 And here we set all the bins where we have a sutures as an input rate, so we could just add a message 105 00:07:38,300 --> 00:07:47,590 over here setting fifty eight, fifty nine, sixty and sixty one as output. 106 00:07:49,060 --> 00:07:49,390 Right. 107 00:07:49,750 --> 00:07:55,120 So this complete all the initialization of a particular line setting up our direction now we could write 108 00:07:55,510 --> 00:08:01,870 the mean code, which will be running throughout the span of an application. 109 00:08:02,650 --> 00:08:07,780 So to read the reader, what are we going to do is we'll be reading the data from a switch, OK, and 110 00:08:07,780 --> 00:08:11,800 then that data will be applying to the daily rate. 111 00:08:12,130 --> 00:08:19,750 So if you just analyze the driver for hobbyists who do read up in, you had this function and that basically 112 00:08:19,750 --> 00:08:21,230 read and you started right. 113 00:08:21,490 --> 00:08:28,180 So we will be utilizing the same leadership here we required for variable rate so each switch data will 114 00:08:28,180 --> 00:08:30,900 be inside available to you to redo. 115 00:08:32,060 --> 00:08:35,710 OK, we'll just be naming this as zero six one. 116 00:08:36,130 --> 00:08:38,360 Switch two and Switch three. 117 00:08:38,380 --> 00:08:44,200 OK, so these are all variable, which will be holding the data that will be reading utilizing the read 118 00:08:44,210 --> 00:08:45,430 brain function that we have. 119 00:08:45,430 --> 00:08:48,850 So we'll just be initiating them to zero. 120 00:08:50,150 --> 00:08:56,480 OK, so let me just go ahead and try to utilize the redefine function, right, so we just need to pass 121 00:08:56,480 --> 00:08:56,810 an. 122 00:08:57,890 --> 00:08:59,870 Instance structure and a pin number. 123 00:09:00,910 --> 00:09:05,340 So infrastructure is GPO and the pin number for our switches. 124 00:09:05,350 --> 00:09:05,920 Fifty four. 125 00:09:06,760 --> 00:09:12,270 So we apply the same logic for pin number fifty five, fifty six and fifty seven, right? 126 00:09:12,280 --> 00:09:17,590 So far, all the switches will be reading the value and will be storing them in their respective variable. 127 00:09:17,590 --> 00:09:21,520 So for our first function, we will be storing it in zero. 128 00:09:22,450 --> 00:09:30,070 OK, then we have a Switch one, Switch two and then we have a Switch three, right? 129 00:09:31,430 --> 00:09:37,790 Next, we will be writing this data onto respect to early data to do that, we have a function right 130 00:09:37,790 --> 00:09:42,700 thing where we need to specify and instance structure benign data, right? 131 00:09:42,710 --> 00:09:44,330 So let me just go ahead. 132 00:09:45,350 --> 00:09:54,020 So instance structure is GPIO in number we have is fifty eight, OK, which is the first thing where 133 00:09:54,020 --> 00:09:55,130 we have our ability. 134 00:09:55,910 --> 00:10:01,200 Then the data so far, First Lady will just be sending such so right. 135 00:10:02,290 --> 00:10:09,460 Will just be gulping this and pasting it full time rate the next day leads at fifty nine, where we 136 00:10:09,460 --> 00:10:11,470 will be sending the data from search one. 137 00:10:12,670 --> 00:10:16,900 OK, so this complete accord, what are we going to do is we'll also be printing the value that we are 138 00:10:16,900 --> 00:10:19,540 receiving, so that will help us to debugger value, right? 139 00:10:19,870 --> 00:10:20,560 So they'll. 140 00:10:21,580 --> 00:10:23,110 Brain death, OK? 141 00:10:23,680 --> 00:10:28,210 Value read from the switch we'll get to city to. 142 00:10:29,980 --> 00:10:38,010 Switch one switch to the last one is Switch three, right, and the variable which are holding this 143 00:10:38,010 --> 00:10:42,450 value are switches to switch one, switch to Switch three. 144 00:10:43,310 --> 00:10:43,450 Right. 145 00:10:43,500 --> 00:10:48,960 So this allows us to see whether the code is working at the expected rate so we could manipulate the 146 00:10:48,960 --> 00:10:49,540 result. 147 00:10:49,560 --> 00:10:55,980 We could verify the result that we are getting on the diesel console with the Switch Street rate and 148 00:10:55,980 --> 00:10:59,220 will be setting each new value in an interval of two seconds. 149 00:10:59,440 --> 00:11:04,230 So this is an entire logic that we going above perform right to what we are doing. 150 00:11:04,260 --> 00:11:05,880 We are reading the value from a switch. 151 00:11:06,330 --> 00:11:11,460 Then we are applying the same value to the respective values, and we are also printing the values that 152 00:11:11,460 --> 00:11:13,200 we are getting on a switch, right? 153 00:11:13,200 --> 00:11:16,170 So this helps to verify the data with the switch state. 154 00:11:16,530 --> 00:11:21,480 And then we are sensing the value of a switch after an interval of music. 155 00:11:21,810 --> 00:11:28,320 So once you complete the score now, we could just proceed to downloading the program onto an FPGA who 156 00:11:28,320 --> 00:11:30,030 will just hit program FPGA. 157 00:11:30,160 --> 00:11:34,860 OK, this will automatically invoke the big fight that we exported from and we will do. 158 00:11:36,800 --> 00:11:42,560 So once programming is done, we could go ahead where we have our head of the world or see OK and then 159 00:11:42,560 --> 00:11:44,630 right click run as launch. 160 00:11:45,090 --> 00:11:51,800 So before this, what we could do is we could just is to get them in to the respective comfort that 161 00:11:51,800 --> 00:11:56,660 you have right and then proceed to launch on how to write. 162 00:11:58,160 --> 00:12:02,990 Now, if you see all those details, OK, so here we forget to add a new line character. 163 00:12:03,410 --> 00:12:09,470 Yes, we'll will just add a new line character and then will again relaunch our debug session. 164 00:12:11,000 --> 00:12:14,060 So now you could see by default on the Switch are in zero. 165 00:12:14,330 --> 00:12:18,290 So I'll now try to turn on Switch clearly. 166 00:12:18,470 --> 00:12:25,640 So the first and be just turned on, no right that you could see the next one, then next one, right 167 00:12:25,640 --> 00:12:26,680 and then final. 168 00:12:26,780 --> 00:12:31,130 Now you could see all the switch are turned off and respectively, all the ladies are also on. 169 00:12:31,430 --> 00:12:32,360 So now we'll see. 170 00:12:32,840 --> 00:12:33,890 Turn them off, right? 171 00:12:34,040 --> 00:12:41,450 So we will first turn off Switch three, then we will turn or switch to and then switch one and finally 172 00:12:41,450 --> 00:12:42,380 switch seats. 173 00:12:42,530 --> 00:12:42,860 Right? 174 00:12:43,190 --> 00:12:44,860 So the cold is working as expected. 175 00:12:44,900 --> 00:12:53,310 Now you're good now you know how you utilize the e-mail, OK, to sense the signal from the GPIO. 176 00:12:53,330 --> 00:12:59,600 And along with that, we also understand how we applied the signal to the GPI process.
