1 00:00:00,060 --> 00:00:07,860 Now we understood how you in washed up time, so let it just proceed for utilizing the timer, which 2 00:00:07,860 --> 00:00:13,260 is pressing with the zinc processing system that is the private 32bit timer that we have with zinc processing 3 00:00:13,260 --> 00:00:14,970 system right now. 4 00:00:14,970 --> 00:00:20,820 Instead of creating a new project, what we could do is here it will be creating a new application project 5 00:00:21,240 --> 00:00:27,240 because I housing file remain common for both washed up time where as well as the timer. 6 00:00:27,540 --> 00:00:27,770 Right. 7 00:00:27,780 --> 00:00:31,140 So we'll go ahead and we'll create a new application project. 8 00:00:31,140 --> 00:00:32,880 We'll just be naming this chamber. 9 00:00:33,120 --> 00:00:41,040 OK, we will be working with the sea and we'll be utilizing in Hallowell template right now when we 10 00:00:41,850 --> 00:00:43,890 see the system, right? 11 00:00:44,040 --> 00:00:44,430 OK. 12 00:00:44,460 --> 00:00:47,140 That has been created for our time. 13 00:00:47,220 --> 00:00:56,240 OK, so you could clearly see that the table that we required for usage of the 32 bit timer is MCU time, 14 00:00:56,310 --> 00:00:56,560 right? 15 00:00:56,580 --> 00:01:01,140 So we go to the gamer folder, OK? 16 00:01:01,140 --> 00:01:10,080 And then the two things that will be including here is that it follows statics, parameters, storage. 17 00:01:10,110 --> 00:01:10,470 Right? 18 00:01:10,560 --> 00:01:14,190 This will give us all the information related to any hardware. 19 00:01:14,220 --> 00:01:21,620 And then we will be proceeding for adding the driver, which are specific to our 32 bit timer radius 20 00:01:21,660 --> 00:01:24,140 x fcu timer. 21 00:01:25,560 --> 00:01:26,990 So these are the two main thing. 22 00:01:27,000 --> 00:01:29,940 Now we'll explore the API is that we have right? 23 00:01:31,140 --> 00:01:37,680 So it consists of normal mode and reload mode and an intramural again, three modes are their normal 24 00:01:37,680 --> 00:01:43,230 mode and automobile mode will be targeting in this specific section, and introverts will be understanding 25 00:01:43,230 --> 00:01:47,040 when we cover fundamental love and interest rate again, a few. 26 00:01:48,070 --> 00:01:54,250 See the EPA so we have to structure when, for instance, and one for conflict structure, right? 27 00:01:55,420 --> 00:01:59,650 Then we also have an EPA to check whether time is expired or not. 28 00:02:00,070 --> 00:02:04,330 We also have an EPA if we start the timer, OK, a low timer. 29 00:02:04,360 --> 00:02:07,450 These are very similar to what we have in an Vostok. 30 00:02:07,460 --> 00:02:12,340 Namely, we could also take out the value, the current value that our time would have. 31 00:02:12,380 --> 00:02:15,010 OK, then we have an hour to reload. 32 00:02:15,370 --> 00:02:21,460 This will be covering later on when we first discuss the timer without an author. 33 00:02:21,890 --> 00:02:22,160 Great. 34 00:02:22,180 --> 00:02:27,620 And first we'll just be disabling in a little later on, we will be enabling it and trying to see the 35 00:02:27,620 --> 00:02:32,290 effect that we get with an to look great in trouble or be covering over here. 36 00:02:32,920 --> 00:02:40,410 So we have look up config see of judicial circuit straight and then EPA to start and stop, right? 37 00:02:40,420 --> 00:02:41,820 So we also have a peace killer. 38 00:02:41,850 --> 00:02:48,580 We will be separate separately for initiating a peace killer so this could be used to control the clock 39 00:02:48,580 --> 00:02:49,210 frequency. 40 00:02:49,270 --> 00:02:49,540 Right? 41 00:02:49,840 --> 00:02:55,630 So let me just follow a normal procedure for us to initialize our time, or it will again be performing 42 00:02:55,630 --> 00:02:58,060 the cell test for this intermediate pacing rate. 43 00:02:59,220 --> 00:03:04,190 So the new structure that we required is the first one that is the. 44 00:03:05,430 --> 00:03:06,480 Instant structure. 45 00:03:06,600 --> 00:03:09,300 So this will just be naming as. 46 00:03:11,110 --> 00:03:15,640 As Sue Time and then we have a conflict structure, right, so we'll just be declaring it. 47 00:03:16,210 --> 00:03:21,340 This will be again a pointer, so sue dmaa and then we have a conflict, right? 48 00:03:21,760 --> 00:03:25,570 This will be declaring again as a pointer, so we proceed with the light. 49 00:03:25,960 --> 00:03:28,240 And this will be our timer in it. 50 00:03:29,630 --> 00:03:33,980 OK, so let me just go ahead and try to add a look up country first. 51 00:03:34,370 --> 00:03:40,100 This again returned the conflict structure, which will be connecting to our a seal team config structure 52 00:03:40,100 --> 00:03:41,000 that we have our data. 53 00:03:41,000 --> 00:03:43,990 We have Rachel S.U. time conflict. 54 00:03:44,000 --> 00:03:46,020 This will be equals to look of conflict. 55 00:03:46,040 --> 00:03:51,290 And here we just need to specify the device A.D. So we go to experimental dotage. 56 00:03:51,710 --> 00:03:53,810 Look for the timer. 57 00:03:55,090 --> 00:03:58,410 So here we have a sea, you right? 58 00:03:58,570 --> 00:04:03,070 This is the device that we need to specify to our look up config function. 59 00:04:03,850 --> 00:04:06,010 Let me just go ahead and take over here. 60 00:04:06,050 --> 00:04:06,300 Right. 61 00:04:06,310 --> 00:04:07,810 So this is the first thing that we do. 62 00:04:08,290 --> 00:04:15,130 Then we call CFD, initialize rate targeting this rate and the status, which will be used to verify 63 00:04:15,130 --> 00:04:17,260 whether initialization is successful or not. 64 00:04:17,320 --> 00:04:17,520 Right. 65 00:04:17,540 --> 00:04:25,660 So in status and it should be equal to CFD initialize, we need to pass an instance structure, which 66 00:04:25,660 --> 00:04:32,740 is this you dmaa in orchestrating the config structures so you DMA config. 67 00:04:32,740 --> 00:04:39,190 And the last thing that we do is to specify the visitors to see you. 68 00:04:39,770 --> 00:04:43,360 You mark config and then be set straight. 69 00:04:44,080 --> 00:04:49,480 So here we'll just be verifying whether initialization is successful or not, so we could just copy 70 00:04:49,480 --> 00:04:53,580 the code from my previous project rate. 71 00:04:53,590 --> 00:04:55,990 This both the thing we will be performing. 72 00:04:55,990 --> 00:05:01,300 So we'll just be copying this and see that since we have both the files with the same name, as soon 73 00:05:01,300 --> 00:05:05,490 as you copy anything from our previous code, you just need to close it. 74 00:05:05,500 --> 00:05:07,150 Okay, so you do not. 75 00:05:08,030 --> 00:05:16,940 Modify the code from a previous application rate, so we'll just be copying whatever thing that we require 76 00:05:16,940 --> 00:05:21,460 and then we'll be immediately closing it, so this will avoid a confusion in the keys if you have the 77 00:05:21,470 --> 00:05:23,030 main file with the scene, right? 78 00:05:23,510 --> 00:05:31,460 So if you do this access, we'll just be mentioning that timer and it is successful and stammering again, 79 00:05:31,460 --> 00:05:33,800 then will again be performing a self-test so far. 80 00:05:33,800 --> 00:05:37,850 So we do have a dedicated API, right? 81 00:05:37,880 --> 00:05:38,900 So we'll just be copying. 82 00:05:38,900 --> 00:05:44,960 It will be adding it over here and that we just need to pass an instance structure. 83 00:05:44,990 --> 00:05:52,670 So did a see you TMA right and will again be checking whether this is successful or not? 84 00:05:52,700 --> 00:05:52,970 Right. 85 00:05:53,390 --> 00:05:57,860 This complete our initialization code for our timer will just be calling it over here. 86 00:05:57,890 --> 00:06:07,460 So for us, the function is dmaa and it will just be calling it over here and then we will be performing 87 00:06:07,910 --> 00:06:08,330 the. 88 00:06:09,350 --> 00:06:10,720 Verification of disclosure. 89 00:06:11,030 --> 00:06:14,360 So let me just go ahead and try to force program and if you. 90 00:06:15,790 --> 00:06:22,060 Squad's programming is successful, will just be clearing up, and so in fact, we will, because disconnecting 91 00:06:22,060 --> 00:06:25,460 it and then we will begin connecting it at scene. 92 00:06:26,090 --> 00:06:33,010 Right now, we need to select this folder, OK, that we want to execute. 93 00:06:33,370 --> 00:06:37,360 So right click here, unless your end configuration. 94 00:06:37,360 --> 00:06:42,760 Right now, you'll be finding you do have an existing configuration over here, which belongs to our 95 00:06:42,760 --> 00:06:43,750 previous application. 96 00:06:44,050 --> 00:06:50,680 OK, so you could delete it, or you could keep it as it is, and then right click run as long as you 97 00:06:50,680 --> 00:06:50,860 want. 98 00:06:51,220 --> 00:06:57,490 So this will create the new launch configuration and that will be executed, right? 99 00:06:58,060 --> 00:07:05,860 So now you will see that timer initialization is successful and self-test is also right to be correctly 100 00:07:05,860 --> 00:07:09,940 able to initialize a timer, as well as we able to perform the self-test. 101 00:07:09,970 --> 00:07:14,220 Now that it just prosody and try to explore the API that we have, right? 102 00:07:15,070 --> 00:07:20,560 So we first need to disable our reload mode since that is not what we wanted to do here. 103 00:07:20,650 --> 00:07:25,100 So let it just go and use disable auto reload, right? 104 00:07:25,450 --> 00:07:27,910 Will be understanding the meaning and usage of it. 105 00:07:27,910 --> 00:07:32,630 As we progress for right here, we just need to pass an instance. 106 00:07:32,640 --> 00:07:34,150 So this is the first thing that we do. 107 00:07:34,960 --> 00:07:38,620 Then the next thing is to load account great again. 108 00:07:38,710 --> 00:07:43,150 Let's assume that we want to have a delay of five second rate. 109 00:07:43,150 --> 00:07:46,150 Does it again work at half of the frequency? 110 00:07:46,420 --> 00:07:53,440 So for us, the timer count will be latest as you are already low. 111 00:07:53,480 --> 00:07:59,800 Five second is three three three three three three three three three three three three three megahertz 112 00:08:00,220 --> 00:08:01,830 and multiply by fight rate. 113 00:08:01,840 --> 00:08:08,320 This will give us a delay of five second and we'll go ahead and load this value into our timer, right? 114 00:08:08,440 --> 00:08:11,740 So to do that, we do have an EPA. 115 00:08:12,910 --> 00:08:19,510 So we have a little time where it will just be copying this will be adding here and then here we need 116 00:08:19,510 --> 00:08:25,390 to pass an instance and along with this, we need to parcel value, right? 117 00:08:25,810 --> 00:08:28,780 This will load our time right. 118 00:08:29,290 --> 00:08:35,170 Before starting our time when we first need to purposefully call the stop. 119 00:08:36,520 --> 00:08:37,480 And then. 120 00:08:38,720 --> 00:08:41,440 We will be starting our time, right, so here. 121 00:08:42,140 --> 00:08:43,010 Just go ahead. 122 00:08:44,420 --> 00:08:47,240 And then we will be calling the stock great. 123 00:08:48,480 --> 00:08:50,940 Now, what are we going to do is? 124 00:08:52,280 --> 00:08:55,670 So litigious, proceed with utilizing dysfunction right now. 125 00:08:55,910 --> 00:09:02,540 This will notify by the time where it expired or not, so true if time has expired, so we will just 126 00:09:02,540 --> 00:09:05,450 be waiting until timer right the white. 127 00:09:06,750 --> 00:09:14,250 So this will continuously routine falls, OK, to the time counter reaches to the specified rate that 128 00:09:14,250 --> 00:09:20,760 its timer expired, so we'll just be adding another tool here, right? 129 00:09:20,760 --> 00:09:22,810 And then we'll be adding this function. 130 00:09:22,830 --> 00:09:24,480 We just need to pass an instant. 131 00:09:24,480 --> 00:09:31,080 So it's you know, what this will do is this will be continuously waiting until the timer expired and 132 00:09:31,080 --> 00:09:33,270 in-between with the small delay. 133 00:09:33,620 --> 00:09:33,870 Right. 134 00:09:33,870 --> 00:09:42,900 So let me just add a delay of two hundred microsecond right, and will be randomly printing the value 135 00:09:42,900 --> 00:09:44,570 that we are having on the counter right. 136 00:09:44,580 --> 00:09:49,440 So will also be our understanding where the country is going up and down, where those counters going 137 00:09:49,440 --> 00:09:49,770 down. 138 00:09:50,310 --> 00:09:58,350 And then we, as we come out of the white look, we'll just be mentioning that our. 139 00:09:59,440 --> 00:10:08,370 Timer, ex-spy, right, that is you basically reach to the delay of a delay of five seconds. 140 00:10:08,620 --> 00:10:10,660 This is what we're going to do over here. 141 00:10:11,110 --> 00:10:16,600 So let me just go ahead and try to randomly pick up the value for our counter and for that, we do have 142 00:10:16,600 --> 00:10:17,080 an EPA. 143 00:10:17,080 --> 00:10:21,040 So we have a good counter value and this basically rate and utility rate. 144 00:10:21,040 --> 00:10:24,370 So we shouldn't just be hiding one variable. 145 00:10:25,720 --> 00:10:34,420 So just go ahead and add one variable and count value, right with visualising it to a zero. 146 00:10:35,550 --> 00:10:42,310 To count value will be equal to the function that we have, and here we just need to pass an instance, 147 00:10:42,310 --> 00:10:44,310 so it is absolutely right. 148 00:10:44,850 --> 00:10:47,590 And along with this will also be printing this value, right? 149 00:10:47,610 --> 00:10:51,470 So this will happen in an interval of two hundred microseconds, right? 150 00:10:52,620 --> 00:10:56,910 So two hundred microsecond is very low, period, that's compared to five second. 151 00:10:57,450 --> 00:11:04,660 They just go it like two thousand to 1000 microsecond basically mean it is two millisecond rate. 152 00:11:04,660 --> 00:11:06,120 Two will add one more zero. 153 00:11:06,450 --> 00:11:08,110 This will be 20 milliseconds. 154 00:11:08,110 --> 00:11:13,230 And then or instead of, we could just walk around with ten millisecond rate. 155 00:11:13,230 --> 00:11:17,520 So we'll just look whether this function is still not. 156 00:11:18,780 --> 00:11:22,020 So a year we'll just be adding the is that it will. 157 00:11:23,270 --> 00:11:31,280 A blue light as a delay of two hundred milliseconds, so the three zero that will be basically converting 158 00:11:31,790 --> 00:11:34,470 micro to me and then two hundred millisecond rate. 159 00:11:34,490 --> 00:11:43,130 So when we reach to five second, we'll be finding less number of the reportings off in there on the 160 00:11:43,140 --> 00:11:50,960 con. Let it just go and try to bring the value right to the account value. 161 00:11:52,080 --> 00:11:53,040 I've seen 0d. 162 00:11:54,040 --> 00:11:57,760 OK, and we will be printing the value of count value, right? 163 00:11:58,360 --> 00:11:59,950 So this will be our entire logic. 164 00:11:59,950 --> 00:12:02,740 What we are doing is we are waiting for our timer to expire. 165 00:12:03,070 --> 00:12:08,770 So this will be continuously running till the counter reaches to the ground that we specify. 166 00:12:08,830 --> 00:12:09,190 OK. 167 00:12:09,220 --> 00:12:11,140 Again, it is in down counter. 168 00:12:11,540 --> 00:12:18,220 So as soon as we expect soon as a timer expired, we'll just be displaying this message. 169 00:12:18,460 --> 00:12:25,600 So we'll just go ahead and try to perform an execution of a call so things will become much more easier 170 00:12:25,600 --> 00:12:26,310 to understand, right? 171 00:12:26,830 --> 00:12:32,410 So we already programmed refugee while checking whether initialization is successful or not. 172 00:12:32,410 --> 00:12:35,740 So we just need to perform the same configuration. 173 00:12:35,890 --> 00:12:37,630 OK, on to a refugee. 174 00:12:39,030 --> 00:12:41,460 So now you could see the counter values. 175 00:12:41,500 --> 00:12:48,500 OK, so we started at a maximum 32 bit value again, then we are coming down so you could actually see 176 00:12:48,500 --> 00:12:51,050 the values I decree my dog again. 177 00:12:51,050 --> 00:12:52,280 This interval is. 178 00:12:53,590 --> 00:12:54,010 All. 179 00:12:55,130 --> 00:13:01,130 Two hundred millisecond rate, so we will do find out so if you can see the one second. 180 00:13:01,220 --> 00:13:04,520 We have five values right to five. 181 00:13:04,520 --> 00:13:08,210 Values should be printed within one two to one two three four five. 182 00:13:08,320 --> 00:13:08,590 Right. 183 00:13:08,600 --> 00:13:17,450 So this represent one taking one two three four five two second one two three four five three second 184 00:13:17,450 --> 00:13:23,840 one two three four and five four second one, two, three, four and five. 185 00:13:23,870 --> 00:13:30,470 Then you could clearly see that count or expired, and we get time where right, so this is working 186 00:13:30,480 --> 00:13:31,220 as expected. 187 00:13:31,460 --> 00:13:33,600 So this is how you'll be operating a counter. 188 00:13:33,620 --> 00:13:34,920 You go ahead first. 189 00:13:34,940 --> 00:13:39,120 So we learn how to load more now as we progress and listen in and to learn more. 190 00:13:39,140 --> 00:13:42,710 So depending on an application, you could actually utilize an auto reload more. 191 00:13:43,010 --> 00:13:43,340 OK. 192 00:13:44,000 --> 00:13:51,770 And this will keep a track of the timing, so you could measure whether the specific timing is made 193 00:13:51,770 --> 00:13:54,770 by an EPA is or would you be utilizing this to? 194 00:13:56,210 --> 00:13:57,870 Use for timing applications. 195 00:13:58,100 --> 00:14:05,120 So what we did is we found the specific time that we weren't great and that count we have loaded into 196 00:14:05,120 --> 00:14:05,630 a timer. 197 00:14:05,810 --> 00:14:13,610 Then usually when we start working with the timers, we first stop a timer purposefully and then we 198 00:14:13,790 --> 00:14:14,710 started right. 199 00:14:14,930 --> 00:14:20,780 We are waiting for timer to expire and in-between what we are doing is we are getting the random count 200 00:14:20,780 --> 00:14:22,400 to evaluate that specific instance. 201 00:14:22,400 --> 00:14:26,780 We are bringing that value and this we are doing in an interval of two hundred milliseconds. 202 00:14:27,500 --> 00:14:28,850 And as soon as we. 203 00:14:29,980 --> 00:14:35,630 A reach to zero, we basically print timer, right? 204 00:14:36,190 --> 00:14:38,440 So this is our to work from this. 205 00:14:38,440 --> 00:14:44,140 Also, it is clear, it is clear that our timer is going in and out. 206 00:14:44,140 --> 00:14:45,040 We are right. 207 00:14:45,280 --> 00:14:50,290 So let me just go ahead and try to exclude the other thing that we have not covered here that is pre-schooler 208 00:14:50,290 --> 00:14:52,530 as well as the auto reload.
