1 00:00:00,120 --> 00:00:06,930 First thing, as you complete your initialization is to purposefully stop the timer rate, then you 2 00:00:06,930 --> 00:00:10,950 perform the required configuration and then you start looking at only the timer. 3 00:00:11,070 --> 00:00:15,420 So this required an instant structure, which is still right. 4 00:00:15,420 --> 00:00:18,180 So we have purposefully stop our. 5 00:00:19,170 --> 00:00:25,410 Timer, OK, then I do not first worry about pre-schooler, right, so let's adjust the rule account 6 00:00:25,860 --> 00:00:29,250 and then disable the auto reload. 7 00:00:29,490 --> 00:00:34,440 Now we know that the timer have two modes of operation, right, normally more than an hour to reload 8 00:00:34,440 --> 00:00:34,680 mode. 9 00:00:34,690 --> 00:00:36,950 So first, let's just focus on a normal mode. 10 00:00:36,960 --> 00:00:40,050 And to do that, we need to disable an auto mode. 11 00:00:40,140 --> 00:00:41,760 And this is the function to do that. 12 00:00:41,760 --> 00:00:44,010 So this just requires an instant structure, right? 13 00:00:44,400 --> 00:00:47,580 So we go ahead and call this function. 14 00:00:47,610 --> 00:00:51,150 OK, here we mentioned the instant structure, which is to my right. 15 00:00:51,480 --> 00:00:58,080 So this basically mean that we are working in normal. 16 00:00:59,130 --> 00:00:59,790 More great. 17 00:01:00,720 --> 00:01:08,020 So once this is done, we go ahead and then we have a function to lower the time. 18 00:01:08,310 --> 00:01:10,320 So again, the. 19 00:01:11,640 --> 00:01:16,050 The deal is that we want to achieve out of a time where it is five chicken, and we already know that 20 00:01:16,050 --> 00:01:21,210 since it is operating at half of the frequency that is three three three megahertz, we just need to 21 00:01:21,210 --> 00:01:23,100 specify discount rate. 22 00:01:23,370 --> 00:01:30,210 So we go ahead and try to look for the argument size that they except accept rates so low. 23 00:01:30,230 --> 00:01:33,510 Taylor accept the value in a new digital format, right? 24 00:01:33,510 --> 00:01:36,160 So you declared a new 32 variable. 25 00:01:36,180 --> 00:01:37,830 So I hear you that you do. 26 00:01:38,190 --> 00:01:42,570 They just need this as demo count. 27 00:01:42,650 --> 00:01:47,550 OK, and this will be close to three three three three three three three three three. 28 00:01:47,780 --> 00:01:50,710 So this is three three three megahertz cross. 29 00:01:50,850 --> 00:01:51,270 Five. 30 00:01:51,570 --> 00:01:57,180 So this is the count that you need to add for achieving a delay of five second rate. 31 00:01:57,180 --> 00:02:00,060 So we go ahead and call this low timer. 32 00:02:00,300 --> 00:02:03,870 This required an instance pointer and the account value rate. 33 00:02:05,310 --> 00:02:11,460 So low tamer first argument is an instance that your religious steamer and then you need to specify 34 00:02:11,460 --> 00:02:12,480 the count railroad. 35 00:02:12,500 --> 00:02:15,880 So this is in the DMR count variable, right? 36 00:02:15,880 --> 00:02:21,510 So once you correctly load the timer, the next function that we call this? 37 00:02:23,070 --> 00:02:24,390 The ACU. 38 00:02:25,460 --> 00:02:31,550 Timer is expired or not great, so let me just call this function and we will be waiting for our timer 39 00:02:31,550 --> 00:02:37,850 to expire and then do something right, for example, it will return through OK if timer has expired. 40 00:02:37,850 --> 00:02:40,520 So the delay that we specified as soon as. 41 00:02:41,690 --> 00:02:43,320 It reaches to a value of zero. 42 00:02:43,360 --> 00:02:45,660 That basically mean the timer is expired. 43 00:02:45,860 --> 00:02:50,830 And in that case, it will be returning to rate is forested. 44 00:02:50,840 --> 00:02:52,760 The Spaniard will be returning false rate. 45 00:02:52,770 --> 00:02:59,990 So if we plan to use OK while look great, so they just add where you look great. 46 00:03:00,170 --> 00:03:06,450 So we want that our processor should we to were here till we complete the five second period. 47 00:03:06,690 --> 00:03:08,580 And since this return, false. 48 00:03:08,600 --> 00:03:08,960 OK. 49 00:03:09,170 --> 00:03:15,120 The function that we seen over here since this riordan's of false rate deal. 50 00:03:15,440 --> 00:03:16,640 The five second bidder. 51 00:03:16,670 --> 00:03:22,400 So we need to add a note operator so that while true, and then we will be while we come true and will 52 00:03:22,400 --> 00:03:28,130 be waiting over here to just add the exclamation mark, OK, which represent the note operator, then 53 00:03:28,130 --> 00:03:28,820 the function. 54 00:03:29,300 --> 00:03:32,090 And finally, this requires OK. 55 00:03:32,420 --> 00:03:34,640 The instance of queue, which is an argument, right? 56 00:03:34,640 --> 00:03:41,570 So DMA now what will happen is still our timer is counting the delay of five second rate. 57 00:03:41,840 --> 00:03:43,040 This function will return. 58 00:03:43,040 --> 00:03:44,090 False and normal. 59 00:03:44,120 --> 00:03:45,410 False will be true. 60 00:03:45,770 --> 00:03:46,100 OK. 61 00:03:46,220 --> 00:03:50,990 So while true, we will be waiting over here and as soon as our timer is expired. 62 00:03:51,050 --> 00:03:55,340 OK, so this will return true and not approval before 10 will be coming out of this. 63 00:03:55,760 --> 00:03:56,000 Right? 64 00:03:56,330 --> 00:04:01,220 So we go ahead and here we add the status says OK. 65 00:04:02,190 --> 00:04:06,180 DeLay of five second. 66 00:04:07,790 --> 00:04:09,050 We could also mention. 67 00:04:10,010 --> 00:04:10,820 TMR. 68 00:04:12,110 --> 00:04:12,950 Expired. 69 00:04:13,110 --> 00:04:15,890 OK, so delay of five six accumulate. 70 00:04:17,310 --> 00:04:23,250 No, only thing that we need to do is before we are checking whether time is expired or not, we need 71 00:04:23,250 --> 00:04:24,660 to start our time right. 72 00:04:24,660 --> 00:04:27,090 So to do that, we have a functions. 73 00:04:27,150 --> 00:04:32,260 OK, so if you go down here, you have a function to start and stop the timer. 74 00:04:32,450 --> 00:04:39,330 So let me just call the Stop API, and this also required a single argument, which is an instance set, 75 00:04:39,450 --> 00:04:39,720 right? 76 00:04:39,720 --> 00:04:43,300 So we go ahead and we call this function OK. 77 00:04:43,300 --> 00:04:46,890 And here we had an instance set your registry, right? 78 00:04:46,890 --> 00:04:49,470 So this completes the entire code, right? 79 00:04:49,500 --> 00:04:53,690 So that could be useful to demonstrate how our remove workaround, right? 80 00:04:53,700 --> 00:04:59,190 So you'll be finding first we perform an initialization, then we perform a self-test. 81 00:04:59,490 --> 00:05:03,900 The first thing that we do is to stop the timer forcefully. 82 00:05:04,270 --> 00:05:06,030 OK, then set up the correct move. 83 00:05:06,060 --> 00:05:09,000 Here we set up the timer to operate in a normal. 84 00:05:09,240 --> 00:05:13,530 We load the count to a timer and then we have started the timer, right? 85 00:05:14,280 --> 00:05:18,830 Here we are, waiting for a timer to reach to a zero. 86 00:05:18,840 --> 00:05:21,690 That basically mean we are working in a full mode. 87 00:05:21,690 --> 00:05:26,940 And as soon as our timer expires, OK, we will be coming out of this wide loop. 88 00:05:26,940 --> 00:05:35,630 And then we mention this to end user by sending the string to a console that is timer expired and we 89 00:05:35,640 --> 00:05:38,080 able to achieve a delay of five seconds. 90 00:05:38,110 --> 00:05:38,370 Right. 91 00:05:38,370 --> 00:05:41,400 So let me just go ahead and first build our application project. 92 00:05:41,730 --> 00:05:42,840 So breast control. 93 00:05:43,050 --> 00:05:49,020 This will start the process of building your application project to once be successful. 94 00:05:49,260 --> 00:05:50,040 Now remember. 95 00:05:51,490 --> 00:05:52,870 In our previous case. 96 00:05:53,950 --> 00:05:56,140 It should be, Emma, right? 97 00:05:57,480 --> 00:06:02,140 So now again, proceed for building the project to build a successful. 98 00:06:02,160 --> 00:06:08,670 We already know that in the previous case, we are utilizing the watchdog Daimler application project 99 00:06:08,670 --> 00:06:08,910 great. 100 00:06:08,910 --> 00:06:12,110 So the DBA configuration is for the watchdog timer. 101 00:06:12,120 --> 00:06:15,570 We need to modify our configuration, right? 102 00:06:15,570 --> 00:06:20,700 So how we do that is we just select this dimer as blue application project. 103 00:06:20,700 --> 00:06:21,960 Right click Debug. 104 00:06:21,980 --> 00:06:23,880 Yes, OK, launch on hardware. 105 00:06:24,990 --> 00:06:33,420 So this will choose the debug configuration of a timer, OK, and that could be noticed by reading the 106 00:06:33,420 --> 00:06:34,700 name for our debugger. 107 00:06:34,900 --> 00:06:39,240 So here we have a system debugger and the school dimer, and the score is different. 108 00:06:39,280 --> 00:06:43,920 This basically means our current debug configuration is the timer, right? 109 00:06:43,920 --> 00:06:47,340 So what this is done, what we're going to do is. 110 00:06:48,850 --> 00:06:55,960 Now, here's how you recognize whether you correctly debugging the correct debug configuration. 111 00:06:56,230 --> 00:07:00,520 Just need to read the debugger with your right. 112 00:07:00,530 --> 00:07:05,500 So the system debugger on this code timer and the score is still blue and the system rates of timer, 113 00:07:05,500 --> 00:07:07,930 and this is what we want to verify. 114 00:07:08,500 --> 00:07:12,520 So this basically mean we have chosen the correct application project to execute, right? 115 00:07:12,760 --> 00:07:18,730 So once our programming is successful, we go to a write system, will select the respective compile 116 00:07:18,730 --> 00:07:19,870 and connect to a serial. 117 00:07:19,870 --> 00:07:20,650 Tell Rachel. 118 00:07:20,650 --> 00:07:25,240 As this is done, we go ahead and we need to just click on a resume button, right? 119 00:07:25,240 --> 00:07:27,850 So you would see timeout and you did six this time herself. 120 00:07:27,860 --> 00:07:28,870 That's just successful. 121 00:07:29,260 --> 00:07:35,570 And after a delay of five seconds, you could clearly observe that we get the delay of five seconds.
