1 00:00:00,060 --> 00:00:05,130 So let's consider this simple application, what we're going to do is DTC will be generating a delay 2 00:00:05,400 --> 00:00:07,370 for UPI. 3 00:00:07,470 --> 00:00:09,720 OK, so we'll be utilizing in my OLED. 4 00:00:10,020 --> 00:00:12,160 And then we'll to having a blinking effect. 5 00:00:12,360 --> 00:00:14,820 So this will give us an idea how we utilize that. 6 00:00:14,820 --> 00:00:16,450 UGC In an actual scenario today. 7 00:00:16,980 --> 00:00:23,700 So when we consider the basic lock design flaw, I think, OK, we will be nibbling DTC over, which 8 00:00:23,910 --> 00:00:24,750 will be utilizing. 9 00:00:24,750 --> 00:00:28,650 And one more thing that we require is the GPI OLED rate. 10 00:00:28,650 --> 00:00:32,600 So if you go to an email configuration, there are very reliable. 11 00:00:32,830 --> 00:00:35,100 So there you have a duplicate rate. 12 00:00:35,100 --> 00:00:39,480 So this will automatically select or enable all the fifty four pins that we have. 13 00:00:39,760 --> 00:00:40,110 OK. 14 00:00:40,350 --> 00:00:44,220 And we already know that we have an elite connector set, right? 15 00:00:44,250 --> 00:00:45,330 This is what we're going to do. 16 00:00:45,750 --> 00:00:54,320 So once you configure sync pricing system, OK, just generate wrapper and create bitstream out of it, 17 00:00:54,330 --> 00:00:54,570 right? 18 00:00:54,870 --> 00:01:01,380 So once that SIM generation is successful, go to an SDK right now will go through an entire code for 19 00:01:01,380 --> 00:01:03,750 AGP will be required to have a driver GP. 20 00:01:03,750 --> 00:01:11,460 I hope you sign for the required X C, P S S parameter, give us and all the information related to. 21 00:01:12,460 --> 00:01:18,480 Heart rate, we required this structure to certify D.D.S., which consists of an frequency interval 22 00:01:18,500 --> 00:01:23,910 pre-schooler, an option rate that will be utilizing it, our frequency to computing double, as well 23 00:01:23,910 --> 00:01:24,630 as Beachler. 24 00:01:24,630 --> 00:01:30,000 And depending on an operation that we want to perform, we will be selecting a specific option, right? 25 00:01:30,000 --> 00:01:34,470 So we will be selecting an option as interval mode and along with this. 26 00:01:35,900 --> 00:01:43,570 Don't cooperate, so this two option will be enacted, so then we consider an innate function first 27 00:01:43,610 --> 00:01:50,300 for GPIO required this to structure first one is an instance structure and conflict structure. 28 00:01:50,420 --> 00:01:57,040 Similarly, 42C also required an instance structure as well as in conflict structure when we go to doing 29 00:01:57,050 --> 00:02:01,010 it function, so we declared a single variable to do this. 30 00:02:01,580 --> 00:02:07,820 First, we'll be looking for GPI, always A.D., and we'll be generating a value for our config structure. 31 00:02:07,960 --> 00:02:08,120 Right. 32 00:02:08,120 --> 00:02:16,280 So once we have in conflict structure value for our you will be utilizing CFG initialize OK to initialize 33 00:02:16,280 --> 00:02:17,210 our GPI, right? 34 00:02:17,210 --> 00:02:23,090 So we'll be specifying an instance structure, config, structure, end the etc. So this will be retaining 35 00:02:23,090 --> 00:02:23,660 this data. 36 00:02:23,660 --> 00:02:26,350 So first will verify whether I. 37 00:02:27,330 --> 00:02:30,320 Device initialization for GPI was successful, right? 38 00:02:30,340 --> 00:02:36,370 So we'll just be comparing it to an existing design, if that is the case, we will be seeing that GPI 39 00:02:36,390 --> 00:02:41,770 initialization is success rate will be utilizing the same status variable to achieve three purpose. 40 00:02:41,790 --> 00:02:47,130 So you're checking whether initialization for GPI is successfully checking whether initialization for 41 00:02:47,220 --> 00:02:49,920 UTC successful and lasting is performing. 42 00:02:49,920 --> 00:02:52,680 The self-test for duties right now will go. 43 00:02:52,710 --> 00:02:58,680 It will generate the config structure for our DTC by utilizing again the lookup config function, passing 44 00:02:58,680 --> 00:03:02,190 that device Haiti and then utilizing CFG initialize. 45 00:03:02,610 --> 00:03:08,360 We will be initializing heart rate again, will be connecting students to see of generation. 46 00:03:08,770 --> 00:03:13,680 So after this, we will be verifying whether status is access to success. 47 00:03:13,700 --> 00:03:18,230 And if that is the case, we will be seeing that DDC initialization is success, right? 48 00:03:18,630 --> 00:03:24,840 The last hope that we will be performing at an intermediate bit is that it is to verify their set distribution, 49 00:03:24,840 --> 00:03:25,110 right? 50 00:03:25,500 --> 00:03:31,590 So we'll be calling a self-test from our DTC driver and then we just need to pass an instance structure. 51 00:03:31,620 --> 00:03:36,390 Right now, we will again be verifying whether this is equal access to success. 52 00:03:36,390 --> 00:03:41,810 If that is the case, we will be saying that if this is successful and self-destruct, right? 53 00:03:41,850 --> 00:03:47,990 So these are the three check that we are performing and two initialization we are doing were here one 54 00:03:48,000 --> 00:03:51,090 to initialize our GPO and either to initialize our ADC. 55 00:03:51,450 --> 00:03:55,020 Now this init function, we will be calling and not mean program rates. 56 00:03:55,060 --> 00:04:01,230 They need platform which will initialize a you pay for it and then unit which will initialize our. 57 00:04:02,310 --> 00:04:09,090 DuPont, as well as duties right off evil, we are considering of you, Typekit will be holding an lead. 58 00:04:09,210 --> 00:04:12,980 In fact, we just need to work it with analysts right there. 59 00:04:12,990 --> 00:04:19,650 Let's be of this will be sending or taking on an elite events since we only have a single entity connected 60 00:04:19,650 --> 00:04:20,660 to any my right. 61 00:04:21,210 --> 00:04:26,060 So setting up a direction pin number seven or a minus seven is where we have energy. 62 00:04:26,070 --> 00:04:27,540 So we need to set the direction. 63 00:04:27,540 --> 00:04:31,140 And whenever the port is an output port, we also need to enable an output. 64 00:04:31,140 --> 00:04:33,710 So these are the two function that we already discussed. 65 00:04:33,720 --> 00:04:36,700 We need to apply one to both of them, right? 66 00:04:36,720 --> 00:04:43,680 So let's consider the pin number seven as an output port, OK, and then it will also enable and what? 67 00:04:43,920 --> 00:04:44,220 OK. 68 00:04:44,400 --> 00:04:48,720 So the structure we wish to generate the delay of or frequency of a nerd. 69 00:04:48,720 --> 00:04:51,660 So the blinking frequency for a lady is one heart. 70 00:04:51,670 --> 00:04:55,110 So we are just updating a value of one over here and rest. 71 00:04:55,110 --> 00:04:56,070 All right. 72 00:04:56,460 --> 00:05:00,090 Here we are setting an download for our counter at interval mode, right? 73 00:05:00,660 --> 00:05:07,080 Then once we update the reader option, that is to remember that we have an structure will just be utilizing, 74 00:05:07,080 --> 00:05:14,190 said the option to set said the option that we described in the bow line do RTC right. 75 00:05:14,550 --> 00:05:18,290 Then we would be calculating an interval like this killer from our frequency. 76 00:05:18,300 --> 00:05:20,730 We just need to pass an output frequency, which is what? 77 00:05:21,240 --> 00:05:21,600 OK? 78 00:05:21,870 --> 00:05:23,540 And then interval and be scalar. 79 00:05:23,820 --> 00:05:26,160 I will be computing from this frequency, right? 80 00:05:26,160 --> 00:05:30,030 So once we get an interval n frequency, so here we initialize them to zero. 81 00:05:30,450 --> 00:05:36,180 We'll just be calling set pre-schooler and send Interval Oogie to set the specific value that have been 82 00:05:36,990 --> 00:05:39,990 generated from calculate interval from frequency function. 83 00:05:40,020 --> 00:05:40,290 Right. 84 00:05:40,320 --> 00:05:43,590 Once we complete this, we'll just be going ahead with the Wildwood. 85 00:05:43,890 --> 00:05:49,290 Now specific reason for calling while doing is we want to continuously analyze the blinking effect rate. 86 00:05:49,710 --> 00:05:50,610 We will be starting. 87 00:05:50,610 --> 00:05:53,340 Our DDC will be waiting for timer to reach zero. 88 00:05:53,790 --> 00:06:00,720 OK, then we'll be stopping RDC, resetting the counter value back to what you just specified. 89 00:06:00,990 --> 00:06:04,020 And here we are, just complementing all the LCD. 90 00:06:04,830 --> 00:06:05,150 Right. 91 00:06:05,160 --> 00:06:11,560 So if the initial value is zero, when we perform a compliment, this will give us basically all what 92 00:06:11,580 --> 00:06:11,910 right? 93 00:06:11,910 --> 00:06:17,840 And then we are just utilizing the right thing and applying this value to energy. 94 00:06:17,850 --> 00:06:21,450 Now what this will do is so initial value be zero. 95 00:06:21,690 --> 00:06:27,000 So after an delay of one ticket, we will be having one on an LCD and so on. 96 00:06:27,000 --> 00:06:33,260 And so since we are calling, let's do this again, this entire thing will be repeated, right? 97 00:06:34,570 --> 00:06:36,400 So here we go, I'll just add when. 98 00:06:37,750 --> 00:06:43,440 They'll bring that just to analyze whether we correctly generate the value for our religious right so 99 00:06:43,440 --> 00:06:47,520 we could just display the value of an elderly, and that is what we're going to value. 100 00:06:48,640 --> 00:06:49,150 S.. 101 00:06:50,440 --> 00:06:50,800 OK. 102 00:06:50,950 --> 00:06:57,490 On an LCD is that it just brings the value in then binary format, right? 103 00:06:57,760 --> 00:07:00,610 And we will be creating the value of OLED. 104 00:07:00,940 --> 00:07:05,560 So this will give us an idea of the value that we are sending, in fact, will be actually seeing that 105 00:07:05,560 --> 00:07:06,670 hybrid demonstration. 106 00:07:06,680 --> 00:07:11,170 OK, because am I OLED blinking could actually be a higher rate. 107 00:07:11,560 --> 00:07:14,300 So first thing that we do is to program and FPGA. 108 00:07:16,590 --> 00:07:21,360 So once programming is successful, go ahead and connect to the serial terminal. 109 00:07:21,390 --> 00:07:21,690 Right. 110 00:07:22,020 --> 00:07:26,640 So we will be selecting on four and then we will be executing our application. 111 00:07:26,820 --> 00:07:28,800 All right, let's launch on hardware. 112 00:07:29,960 --> 00:07:35,970 So now you could see that GPIO and it is successful DDC and it is also successful, and so you know, 113 00:07:36,050 --> 00:07:36,900 some success, right? 114 00:07:36,920 --> 00:07:39,420 So we won't be able to see a value of an alibi. 115 00:07:39,440 --> 00:07:44,870 In fact, we also forget to add the new line characters already to score ahead and add a new line character, 116 00:07:44,870 --> 00:07:46,490 and this will be considering it. 117 00:07:46,490 --> 00:07:47,000 So it'll be. 118 00:07:47,950 --> 00:07:51,010 So let's just re launch a debug session. 119 00:07:53,310 --> 00:07:59,600 So now you could see that Dubai, when it is successful, DDC and it is successful and sell this to 120 00:07:59,670 --> 00:08:03,840 the also successful, so here with the binary weren't able to analyze anything. 121 00:08:03,840 --> 00:08:06,240 So let me just proceed to decimal, right? 122 00:08:06,240 --> 00:08:08,490 So once we do this modification? 123 00:08:10,220 --> 00:08:16,670 So now you could see the value that we are sending on energy is zero and 250 rate, and you could actually 124 00:08:16,670 --> 00:08:18,560 observe that blinking on it. 125 00:08:18,620 --> 00:08:19,450 Am I right? 126 00:08:19,460 --> 00:08:26,390 So this is how you can utilize that EDC, OK to need the specific delay or you need a specific frequency 127 00:08:26,390 --> 00:08:27,280 on an output thing.
