1 00:00:03,490 --> 00:00:04,110 Hello, fellas. 2 00:00:04,270 --> 00:00:04,870 Welcome back. 3 00:00:05,260 --> 00:00:10,030 In a section, we're going to learn how to create a D.C. project using the Cube remix. 4 00:00:10,390 --> 00:00:15,580 In this very first lesson, we shall learn how to do a single ADC conversion. 5 00:00:15,780 --> 00:00:17,860 So click over here to create a new project. 6 00:00:19,620 --> 00:00:20,920 And then I'll select my board. 7 00:00:21,490 --> 00:00:25,660 My board is the disco board and it's an F for board. 8 00:00:26,650 --> 00:00:29,000 And this one here is my particular microcontroller. 9 00:00:29,390 --> 00:00:30,580 DoubleClick to choose it. 10 00:00:34,120 --> 00:00:38,890 I just explained to her what I'm going to do, so I'm going to clear the pin out by clicking over her. 11 00:00:40,780 --> 00:00:46,780 And then everything is cleared now for my particular school board of court, just one ADC off court, 12 00:00:46,800 --> 00:00:49,770 just a DC one where I'm going to do it. 13 00:00:49,770 --> 00:00:55,200 So I'm going to come to a DC one and I've got the option to choose from the sixteen channels available. 14 00:00:55,770 --> 00:00:58,170 So I'm just going to start with Channel Zero over here. 15 00:00:58,330 --> 00:01:05,460 So like this in its chosen Channel Zero for me, once that is done, I'll just set my debugger and then 16 00:01:05,460 --> 00:01:07,940 go to configuration to configure the ADC. 17 00:01:08,430 --> 00:01:15,420 Click over here my depolarize the zero wire and once that is done, I just leave the clock configuration 18 00:01:15,660 --> 00:01:20,430 to the default setting and I'll come to configuration over here and then click here. 19 00:01:20,630 --> 00:01:24,600 ATC one for this example, we don't need a lot of changes actually. 20 00:01:25,200 --> 00:01:26,760 So I just click, OK. 21 00:01:27,580 --> 00:01:29,120 Now now generates the code. 22 00:01:29,220 --> 00:01:32,100 Come over here and I'll give my project a name. 23 00:01:33,700 --> 00:01:37,320 I'll call it ADC Single Conversion. 24 00:01:39,460 --> 00:01:42,940 And then I select my two chain, which is the column Decay. 25 00:01:43,640 --> 00:01:45,680 Now click, OK, it's January 10. 26 00:01:46,870 --> 00:01:50,440 And it's finished generates I'll just click over here to open a project. 27 00:01:53,690 --> 00:01:54,080 Right. 28 00:01:54,110 --> 00:01:54,800 It's opened. 29 00:01:55,100 --> 00:01:58,260 So what I want to do is click here to build the whole project. 30 00:02:04,130 --> 00:02:06,890 Once that is done, I can update my D-Box set in. 31 00:02:08,030 --> 00:02:10,510 I just click over here into this box here. 32 00:02:11,280 --> 00:02:11,690 Okay. 33 00:02:12,040 --> 00:02:12,470 Okay. 34 00:02:13,530 --> 00:02:19,660 And then open, what I want to do is start my ADC and start conversion. 35 00:02:19,750 --> 00:02:25,930 And when it finishes the conversion, I want to store the value in a variable which we will create later. 36 00:02:26,230 --> 00:02:27,150 So let's do that now. 37 00:02:27,670 --> 00:02:29,320 So just start the ADC. 38 00:02:29,440 --> 00:02:37,900 We need to use the ADC Start API and we can find the function here by clicking here and selecting the 39 00:02:37,900 --> 00:02:38,670 ADC module. 40 00:02:38,680 --> 00:02:41,890 Here we get a list of API is available to us. 41 00:02:42,460 --> 00:02:44,810 And this one here called How API Stuff. 42 00:02:45,060 --> 00:02:46,510 How ADC Start. 43 00:02:47,510 --> 00:02:48,140 This one here. 44 00:02:48,530 --> 00:02:50,840 It is you start so it can click here. 45 00:02:51,320 --> 00:02:57,590 This one here can read about it here says and it enables ADC starts conversion of regular channels. 46 00:02:58,220 --> 00:03:00,110 And what parameter does it take? 47 00:03:00,140 --> 00:03:03,440 It takes a pointer to the ADC handler structure. 48 00:03:04,220 --> 00:03:06,710 So we just copy this function. 49 00:03:07,950 --> 00:03:08,700 Bring it to Main. 50 00:03:10,760 --> 00:03:12,790 And then we start the ADC back, put in her. 51 00:03:13,910 --> 00:03:18,620 And then we just couldn't use the ADC handler, which is already declared here by Cuba, makes for us. 52 00:03:18,650 --> 00:03:19,700 So we just copy this. 53 00:03:20,330 --> 00:03:22,700 This is the argument of this function. 54 00:03:23,260 --> 00:03:24,500 Let's keep it in here like this. 55 00:03:24,830 --> 00:03:25,760 Put a semicolon. 56 00:03:26,490 --> 00:03:27,920 Now, I've started it, ADC. 57 00:03:28,640 --> 00:03:33,140 So what I want to do next is to pull for conversion, to get a conversion. 58 00:03:33,260 --> 00:03:36,080 We have to use the ADC pull for conversion API. 59 00:03:36,830 --> 00:03:37,580 And it's here. 60 00:03:39,040 --> 00:03:42,700 This one here, how ABC political conversion, so we can take a look at it. 61 00:03:43,200 --> 00:03:49,830 And it takes to document one is the ADC handler and then the other one is the time out. 62 00:03:50,620 --> 00:03:52,380 So I'm just going to copy this as well. 63 00:03:56,110 --> 00:03:57,580 And then poor for conversion. 64 00:03:58,930 --> 00:03:59,560 Copy this. 65 00:03:59,770 --> 00:04:01,060 Take it to my main function. 66 00:04:01,770 --> 00:04:07,500 Put it here and then I'm going to replace this with the NTC one. 67 00:04:09,520 --> 00:04:11,380 I'm going to give it time out of. 68 00:04:12,480 --> 00:04:18,990 In fact, we can give a time out of something as little as one millisecond and put a semicolon there. 69 00:04:20,310 --> 00:04:23,550 So once we've bought for conversion, we have to wait for it to convert. 70 00:04:23,600 --> 00:04:29,730 And we've given a time or two for a millisecond after this, we can use the whole ADC gets conversion, 71 00:04:29,850 --> 00:04:30,480 which is here. 72 00:04:32,200 --> 00:04:36,130 Get value, the ladies, he gets value less, click it and see what he says. 73 00:04:37,250 --> 00:04:43,370 Gets the converted value from data register off regular Chernow's in the parameter pointer to the ADC 74 00:04:43,400 --> 00:04:43,850 handler. 75 00:04:44,270 --> 00:04:48,150 What does a return and returns the converted value to can come over here. 76 00:04:48,190 --> 00:04:48,950 We copy this. 77 00:04:53,280 --> 00:04:54,350 Then we come over here. 78 00:04:55,980 --> 00:04:59,070 Then then we can say. 79 00:05:02,860 --> 00:05:05,500 Get value from the ADC handler like this. 80 00:05:05,800 --> 00:05:07,950 What we want is to keep all of this in the wild. 81 00:05:08,350 --> 00:05:10,260 And this one here returns the ADC file. 82 00:05:10,340 --> 00:05:15,070 So what I'm going to do is I'm going to create a global variable out here, up here to store the ADC 83 00:05:15,070 --> 00:05:22,630 value Grinch and make you into 32 on the school team, sense of value and sense of values going to half 84 00:05:22,630 --> 00:05:23,530 the ADC value. 85 00:05:23,590 --> 00:05:30,260 So I can come over here and see sense of value because all ADC gets value. 86 00:05:30,600 --> 00:05:34,180 And with this, we get the ADC value stored in this global variable for us. 87 00:05:34,420 --> 00:05:40,150 So we can just rebuild, download onto our board and then go to the debug view and put this in a watch 88 00:05:40,150 --> 00:05:42,190 window to see DADT value. 89 00:05:42,430 --> 00:05:48,650 So what I'm going to do is I'm going to connect an analog source to my ADC channel, which is B is you. 90 00:05:48,880 --> 00:05:51,490 What I've got here is a standard potential meta. 91 00:05:51,970 --> 00:05:57,370 I'm going to connect the middle leg of the potential meta to be issue the left leg to ground in the 92 00:05:57,370 --> 00:06:02,500 right like two plus five vote, and then I'm going to turn that potential meta. 93 00:06:02,860 --> 00:06:09,220 And we expect to see the analog value right here to change as I turn the potential meta. 94 00:06:09,610 --> 00:06:10,630 So let's do that now. 95 00:06:10,720 --> 00:06:15,640 And remember, if there's anything you do not understand, send me a message or leave it in the comments 96 00:06:15,640 --> 00:06:16,150 section. 97 00:06:16,480 --> 00:06:18,520 So I click to rebuild my project. 98 00:06:19,650 --> 00:06:22,730 Then once that is done, I'll just click over here to download onto my board. 99 00:06:25,790 --> 00:06:29,730 And once it is done, download it, I can click here to go to the DeBacker. 100 00:06:32,330 --> 00:06:39,050 What you want to do is double click, right, click on the sense of value variable and then to watch 101 00:06:39,050 --> 00:06:40,780 when to want to appear here. 102 00:06:40,870 --> 00:06:42,860 Once it appears we can right. 103 00:06:42,860 --> 00:06:47,270 Click over here to disable the hexadecimal display like this. 104 00:06:47,680 --> 00:06:50,060 And then I'm going to click here to run my code. 105 00:06:51,310 --> 00:06:59,150 And so this the middle value of my current potential meetup position, I'm going to rotate my potential 106 00:06:59,150 --> 00:07:04,810 with me to now, as you can see, I've rotated it to the on the other end of it. 107 00:07:04,990 --> 00:07:10,150 And the value is almost zero now if rotated to the opposite direction. 108 00:07:10,840 --> 00:07:14,530 So, yeah, this is a DC single single conversion mode. 109 00:07:15,000 --> 00:07:16,100 As you can see, it's working. 110 00:07:17,100 --> 00:07:19,750 Are fruitage headed to the other end again and the value down. 111 00:07:20,110 --> 00:07:20,780 So this is it. 112 00:07:20,940 --> 00:07:25,510 And the next lesson, we shall run another ADC application for continuous conversion. 113 00:07:25,870 --> 00:07:27,190 And I see you in the next lesson.
