1 00:00:00,710 --> 00:00:02,430 Hello, and welcome to this annual lesson. 2 00:00:02,450 --> 00:00:11,150 I know you're going to talk about SPF 30 to print out which purpose Input-Output pens should you use. 3 00:00:12,220 --> 00:00:12,530 Now. 4 00:00:14,180 --> 00:00:21,800 This is how the physical layout of that, yes, be board locks, and as you can see, it's very similar 5 00:00:21,800 --> 00:00:31,880 to the Arduino Nano, but it has a lifetime built and now VSP felt too powerful on include 18 analog 6 00:00:31,880 --> 00:00:40,370 to digital converter or ADC channel, where you can receive analog signals, and these signals can be 7 00:00:40,370 --> 00:00:42,230 converted to digital internally. 8 00:00:42,920 --> 00:00:52,670 It also has three USB interfaces for communication and three other interfaces for communication and 9 00:00:52,670 --> 00:00:55,790 to I2C interfaces for Seattle communication. 10 00:00:55,810 --> 00:01:04,010 So these, let's say, eight modules or eight pins can be used to allow cell communication with multiple 11 00:01:04,010 --> 00:01:09,830 devices that support a spy I2C or Isaac Worsley and other art. 12 00:01:10,910 --> 00:01:22,490 It also has 16 P.W. arm output channels, which help, uh, produce an analog output from the ISP pins. 13 00:01:23,120 --> 00:01:28,640 It also has two digital to analog converters and two are two US interfaces. 14 00:01:29,120 --> 00:01:33,890 It also has thin capacitive sensing, sharp elbows, input output. 15 00:01:34,880 --> 00:01:38,550 I provide more data and more details about each of these pens. 16 00:01:39,170 --> 00:01:40,640 And that is also the lecture. 17 00:01:40,910 --> 00:01:46,310 But since we have a lot of them, we don't want to get caught in the details. 18 00:01:46,910 --> 00:01:52,970 Now what we need to know is that print out itself, as you can see, this is how the board looks. 19 00:01:53,510 --> 00:02:01,130 This is the USB port and you are going to hook up your two USB connector here, and the other side will 20 00:02:01,160 --> 00:02:04,430 be connect to your computer, as you can see. 21 00:02:04,550 --> 00:02:10,880 These are the pens g p i o means drought purpose input output. 22 00:02:11,030 --> 00:02:17,510 Now that is more than one general purpose input output, as you can see here, and each of these pens 23 00:02:17,510 --> 00:02:19,070 has more than one function. 24 00:02:20,030 --> 00:02:30,280 As you can see, usually, pens comes with many names each S Pi and ADC analog digital converter and 25 00:02:30,500 --> 00:02:39,680 purpose, and so you can use it as input output pen or to receive analog signal or for us or for all 26 00:02:39,680 --> 00:02:40,130 to see. 27 00:02:41,500 --> 00:02:50,080 So the choice is yours now, as you can see these pins, all of them are numbered for easy access so 28 00:02:50,080 --> 00:02:54,280 that you can easily know what spin is connected to which now. 29 00:02:54,280 --> 00:03:02,020 Additionally, there are pins with specific features that make them suitable or not for a specific project. 30 00:03:02,770 --> 00:03:11,330 The following demonstration shows you some of these pins, and I'm going to talk about each of these 31 00:03:11,350 --> 00:03:15,220 pins entities and if it can be used as input output. 32 00:03:15,430 --> 00:03:18,940 Now the pins highlighted in green here. 33 00:03:20,720 --> 00:03:23,960 I'll show you a table to summarize this information. 34 00:03:26,350 --> 00:03:33,640 Again, the pins highlighted in green are OK to use the ones highlighted in yellow are OK to use, but 35 00:03:33,640 --> 00:03:40,810 you need to pay attention because they may have unexpected behavior, mainly at boat time. 36 00:03:41,650 --> 00:03:47,140 While the pins highlighted in red are not recommended to use as input or output. 37 00:03:47,230 --> 00:03:54,560 Now the general purpose input output pin number zero is, as you can see, OK to use. 38 00:03:54,560 --> 00:04:02,830 But you need to pay extra attention because it may have unexpected behavior at time so it can be used 39 00:04:02,830 --> 00:04:06,070 as a pull up input or as output. 40 00:04:06,520 --> 00:04:15,160 It outputs P.W. signal output, but no one can be used as text pin for other communication or output 41 00:04:15,160 --> 00:04:15,520 pen. 42 00:04:15,940 --> 00:04:24,160 Debug output output PIN number two is OK to be used as input or output, and usually it is connected 43 00:04:24,160 --> 00:04:31,990 to onboard lid so you can use it to test a code or to test our function because you don't have to connect 44 00:04:32,230 --> 00:04:35,380 extra component at all that you have built in. 45 00:04:35,380 --> 00:04:41,830 LED pin number three is OK to use as in both, but you can't use it as output. 46 00:04:42,400 --> 00:04:46,000 It's high output, so it will read one output. 47 00:04:47,630 --> 00:04:55,790 Bin Laden's number four and five are OK to use as Input-Output and PIN number five also outputs P.W. 48 00:04:55,790 --> 00:05:02,360 and signal output bin from six to 11 are connected to the integrated spy flash. 49 00:05:02,870 --> 00:05:12,740 So you can't use them as input or output, but number 12 is OK to yours, but both will fail if bold 50 00:05:12,740 --> 00:05:13,100 high. 51 00:05:13,580 --> 00:05:18,410 So it's OK to use as input, but you need to pay extra attention for this. 52 00:05:18,410 --> 00:05:18,800 Not. 53 00:05:19,520 --> 00:05:22,730 And if you are connecting it as output, it's OK. 54 00:05:22,940 --> 00:05:24,350 You don't have any problems. 55 00:05:24,770 --> 00:05:33,800 Bins from 13 to 16 are OK to be used as input or output without paying extra attention. 56 00:05:34,790 --> 00:05:45,860 Now, as you can see, same four pins from 17 to 33, while 34, 35, 36 and 39 are input only pens. 57 00:05:45,860 --> 00:05:48,770 You can't you can't use them as output. 58 00:05:49,100 --> 00:05:58,910 Now, in our example and our practice tests, we are going to use PIN number two, which has built in 59 00:05:58,910 --> 00:06:00,680 LED, onboard, built and led. 60 00:06:00,980 --> 00:06:07,010 And using that onboard built and led wouldn't make it easier for us to test out or to try different 61 00:06:07,010 --> 00:06:12,140 things if we are making a page with a button to control it via internet. 62 00:06:12,590 --> 00:06:14,660 Now that's it for the pin out. 63 00:06:15,500 --> 00:06:23,540 Now I will add extra information as articles to this section of the course, so let you know more information 64 00:06:23,540 --> 00:06:26,030 about the general purpose input output bins. 65 00:06:26,360 --> 00:06:33,350 But for me, what I need you to know at this point is that we have pins that can be used easily without 66 00:06:33,350 --> 00:06:44,240 any extra attention as input output, which are basically these bins two, four, five, 13 to 16 and 67 00:06:44,240 --> 00:06:46,040 17 to 33. 68 00:06:46,490 --> 00:06:51,650 And if we want and not only pens, we can use 34, 35, 36 or 39. 69 00:06:52,250 --> 00:06:59,180 Now, if we need extra features, if we need BW, I'm ADC or DSC. 70 00:06:59,390 --> 00:07:06,170 If we need a capacitor enabled bean or BW pen, we can go on and check this schematic. 71 00:07:06,170 --> 00:07:15,270 And from these bins, you can see that in our case, Jar Purple Spin Number 36 can be used as a DC of 72 00:07:15,330 --> 00:07:16,340 these converter. 73 00:07:17,970 --> 00:07:24,450 As you can see, and it has what only state you can use this schematic, print it out to refer to it 74 00:07:24,450 --> 00:07:26,100 whenever you need to do something. 75 00:07:26,700 --> 00:07:27,660 Same for here. 76 00:07:27,810 --> 00:07:34,650 You can see from this image that pin number 25 can be used as digital to analog converter and pin number 77 00:07:34,650 --> 00:07:40,470 26 can also be used used as a tool to help converter automatic converter. 78 00:07:42,200 --> 00:07:48,350 So depending on what you need or what's your end goal, you are going to check this schematic and make 79 00:07:48,350 --> 00:07:50,420 sure that you choose the bin that fits your needs. 80 00:07:50,750 --> 00:07:57,410 So if you are going to use a bin as output, you can't use bin number 34 because as you can see here, 81 00:07:57,410 --> 00:07:59,540 it's only input only PIN. 82 00:08:00,530 --> 00:08:06,680 And if you want to use, let's say, analog to digital converter, you can't use this bin bin number 83 00:08:06,680 --> 00:08:15,380 17 because it only supports Syria communication and input output, regular input output or digital input 84 00:08:15,380 --> 00:08:15,950 output. 85 00:08:16,220 --> 00:08:18,430 So before using any bin. 86 00:08:19,820 --> 00:08:26,360 Take a minute or two to make sure that it supports what you are going to do and the sensors or the stuff 87 00:08:26,360 --> 00:08:34,130 that you are going to connect it to, whether they are analog or digital, they are input like push 88 00:08:34,130 --> 00:08:36,470 button or output like LEDs. 89 00:08:36,920 --> 00:08:47,360 You need to connect the element to the right pin before start coding to avoid having problems in the 90 00:08:47,360 --> 00:08:48,020 future. 91 00:08:48,050 --> 00:08:54,590 Once you start testing your code, if you have any question, or if you have a project that you don't 92 00:08:54,710 --> 00:09:00,710 exactly know which bins might fit for that project, you can leave a question in the Q&A board. 93 00:09:01,220 --> 00:09:04,220 I'll be more than happy to help answer all of your concerns. 94 00:09:04,790 --> 00:09:05,760 Thanks for watching. 95 00:09:05,780 --> 00:09:08,130 This is Ashraf from educational engineering team.
