1 00:00:00,570 --> 00:00:06,630 Hello and welcome to this, and you us on LHR going to explain how to deal with analog input. 2 00:00:07,140 --> 00:00:13,320 They ask P32 Board now to test the input analog value signals. 3 00:00:13,500 --> 00:00:20,970 There are about 18 12 bit ADC input channels. 4 00:00:22,100 --> 00:00:26,330 You can easily recognize them from the wiring diagram. 5 00:00:26,840 --> 00:00:32,090 The one that we already mentioned, all of the pin out diagram that we explained in our previous lesson, 6 00:00:33,470 --> 00:00:41,030 and there is only one tin bit and a digital converter on the road to, you know, depending on the ball 7 00:00:41,030 --> 00:00:46,220 that you are using, this pen can be at a different location. 8 00:00:46,460 --> 00:00:47,840 Let me show you the pin out. 9 00:00:49,040 --> 00:00:50,660 Now, as you can see in this image. 10 00:00:52,500 --> 00:00:54,060 You can see the ADC. 11 00:00:55,070 --> 00:01:00,560 Pins, so all of these art and digital converter enabled pens. 12 00:01:01,130 --> 00:01:03,290 And there are other pens as well. 13 00:01:06,300 --> 00:01:08,880 Again, here's issue one. 14 00:01:08,910 --> 00:01:16,200 And these are two so different channels, and you can't recognize them was with a general purpose and 15 00:01:16,200 --> 00:01:20,130 without a pin number starting from then. 16 00:01:20,520 --> 00:01:32,160 As you can see here, Penta has ADC been four point fifteen PIN, one doesn't have ADC, so it's starting 17 00:01:32,160 --> 00:01:33,060 from PIN zero. 18 00:01:33,720 --> 00:01:34,980 Then you can move on. 19 00:01:35,100 --> 00:01:40,040 That has been to four, 12, 13, 14, 15 and so on. 20 00:01:40,070 --> 00:01:43,410 We only need one pin for this lesson. 21 00:01:43,920 --> 00:01:52,230 So to read that and what you will use the same as an Arduino boards, we will use the analog read function 22 00:01:52,230 --> 00:01:53,190 and our coding. 23 00:01:54,890 --> 00:02:02,090 Now, as you can see, the pain that we are going to use for this example is general purpose input output. 24 00:02:02,420 --> 00:02:03,230 36. 25 00:02:03,650 --> 00:02:08,300 It has eight one six zero or child zero. 26 00:02:09,169 --> 00:02:16,700 Now, to reach this value, we need to use the analogy function and we need to store the value on a 27 00:02:16,700 --> 00:02:17,300 variable. 28 00:02:18,050 --> 00:02:22,490 It's very important to note that VSP, P32 and these are convert. 29 00:02:22,490 --> 00:02:30,830 I'll have 12 bits of resolution versus 10 bits on SB eight, two, six six and Arduino. 30 00:02:31,310 --> 00:02:40,670 So the total range of the analog to digital conversion readings can go to 4000 zero nine five or zero 31 00:02:40,670 --> 00:02:52,700 nine two five and a set of 1000 027 on SB eight two six six when a maximum of 3.3 volt is applied to 32 00:02:52,710 --> 00:02:53,150 its end. 33 00:02:53,540 --> 00:03:01,660 So you can expect more values that can go up to 4000 now for input. 34 00:03:01,670 --> 00:03:09,740 Let's use our thinking or potential meter or any analog since all that we have and we can connect it 35 00:03:10,160 --> 00:03:12,800 from the three point three volt and ground. 36 00:03:13,340 --> 00:03:21,410 Now let's use its variable output to be the input of the Speaker 32 ADC pins to get started. 37 00:03:21,710 --> 00:03:23,600 Let's open up Arduino software. 38 00:03:24,440 --> 00:03:26,420 Go for Arduino IEEE. 39 00:03:30,890 --> 00:03:33,980 Now, after opening up our regional I.D.. 40 00:03:36,730 --> 00:03:38,410 It went up the other software. 41 00:03:41,350 --> 00:03:42,790 OK, here it is. 42 00:03:45,140 --> 00:03:46,130 Hardware and software. 43 00:03:48,710 --> 00:03:51,920 Now, the first step that we are going to do is create a new sketch. 44 00:03:52,970 --> 00:03:58,880 Let's make sure that our port is connected and organized, as you can see at come. 45 00:04:00,230 --> 00:04:04,970 And let's make sure that we have the right port selected. 46 00:04:06,490 --> 00:04:08,410 Our case SPF 32. 47 00:04:12,550 --> 00:04:15,710 As you can see, though, it is both hats off to the kids. 48 00:04:16,320 --> 00:04:19,709 And we have other libraries that can cover this. 49 00:04:21,180 --> 00:04:22,770 Now this is our world. 50 00:04:25,200 --> 00:04:26,280 Let's start coding. 51 00:04:26,460 --> 00:04:34,050 The first thing that we need to do is go to the void set up and initialize the serial communication 52 00:04:34,320 --> 00:04:35,730 serial again, 53 00:04:38,730 --> 00:04:46,260 and we can choose anybody that shows eleven thousand five hundred five thousand two hundred. 54 00:04:48,000 --> 00:04:53,610 Um, now let's add a delay so that this kind of supplies. 55 00:04:57,070 --> 00:05:05,500 The Syria communication module and lists print a sentence indicating that we are using ISP. 56 00:05:09,820 --> 00:05:20,520 Thirty two analog and test now up here, let's initialize a variable to save the analog data. 57 00:05:20,530 --> 00:05:23,530 So and analog value. 58 00:05:26,650 --> 00:05:27,610 Equals zero. 59 00:05:29,200 --> 00:05:37,240 Then inside the void loop, right out of value equals analog read just like an angel. 60 00:05:38,500 --> 00:05:42,400 And from here, we need to select the pen lowercase. 61 00:05:42,940 --> 00:05:45,880 Its general purpose input output pen. 62 00:05:46,540 --> 00:05:47,470 Thirty six. 63 00:05:49,640 --> 00:05:57,800 After that, let's print the analog great value, so serial dot print. 64 00:06:03,430 --> 00:06:07,780 Now, loosely based out of Create, which has done a value and decidedly. 65 00:06:11,650 --> 00:06:12,940 Five hundred milliseconds. 66 00:06:13,760 --> 00:06:15,580 OK, let's verify. 67 00:06:17,550 --> 00:06:19,500 Let us save the codes. 68 00:06:20,490 --> 00:06:25,350 Let's call it A. The. 69 00:06:40,710 --> 00:06:42,930 It will take some time to compile a sketch. 70 00:06:51,200 --> 00:06:54,640 Now, let's applaud the sketch. 71 00:06:55,070 --> 00:06:55,980 Yes, be bold. 72 00:06:56,000 --> 00:06:57,860 Make sure that your boards connected. 73 00:06:59,640 --> 00:07:03,480 And you have selected the right board upon the right comport. 74 00:07:06,630 --> 00:07:07,010 OK. 75 00:07:07,050 --> 00:07:10,050 As you can see, it's uploading. 76 00:07:21,830 --> 00:07:22,240 OK. 77 00:07:22,410 --> 00:07:23,180 Writing. 78 00:07:24,560 --> 00:07:25,820 OK, then uploading. 79 00:07:25,850 --> 00:07:33,740 Now, if we went and opened up here, Syria to monitor, OK, we have this science challenge the moderate 80 00:07:34,550 --> 00:07:34,970 to. 81 00:07:36,250 --> 00:07:40,340 One hundred fifteen thousand two hundred, as you can see here, we have zero value. 82 00:07:40,760 --> 00:07:47,060 Now, if you played with the potential meter, you will get values up to 4000. 83 00:07:47,780 --> 00:07:48,590 And that's it. 84 00:07:48,890 --> 00:07:54,830 This is how easy it is to use analog pins on the USB port. 85 00:07:55,490 --> 00:08:00,170 The same Arduino coding, same structure and discipline every line. 86 00:08:00,200 --> 00:08:01,660 Thanks for watching this last one. 87 00:08:01,670 --> 00:08:05,300 If you have any question, please ask in the Q&A about.
