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 00:00:12,300 --> 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 --> 00:00:53,030 It also has three USB interfaces for communication and three up interfaces for communication and to 9 00:00:53,030 --> 00:00:55,790 I2C interfaces for Seattle communication. 10 00:00:55,800 --> 00:01:04,010 So these, let's say, eight modules or eight pens 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 Mercy 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 pens. 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 --> 00:01:41,720 I provide more data and more details about each of these pens and the resources lecture, but since 16 00:01:41,720 --> 00:01:46,310 we have a lot of them, we don't want to get caught in the details. 17 00:01:46,910 --> 00:01:52,970 Now what we need to know is that pen out itself, as you can see, this is how the board looks. 18 00:01:53,540 --> 00:02:01,130 This is the USB port and you are going to hook up your speech connector here, and the other side will 19 00:02:01,160 --> 00:02:04,430 be connect to your computer, as you can see. 20 00:02:04,550 --> 00:02:10,880 These are the pens g p i o means draft purpose input output. 21 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 22 00:02:17,510 --> 00:02:19,070 has more than one function. 23 00:02:20,030 --> 00:02:24,140 As you can see, usually pens comes with many names. 24 00:02:24,470 --> 00:02:30,950 Each S Pi and ADC and digital converter and purpose. 25 00:02:30,950 --> 00:02:40,130 And so you can use it as input output pen or to receive analog signal or for us PI or for all to see. 26 00:02:41,490 --> 00:02:50,070 So the choice is yours now, as you can see these pins, all of them are numbered for easy access so 27 00:02:50,070 --> 00:02:54,300 that you can easily know what spin is connected to which now. 28 00:02:54,300 --> 00:03:02,040 Additionally, there are pins with specific features that make them suitable or not for a specific project. 29 00:03:02,760 --> 00:03:11,300 The following demonstration shows you some of these pins, and I'm going to talk about each of these 30 00:03:11,300 --> 00:03:18,960 spins in details and if it can be used as input output now the pins highlighted in green here. 31 00:03:20,720 --> 00:03:23,960 I'll show you a table to summarize this information. 32 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 33 00:03:33,640 --> 00:03:40,810 you need to pay attention because they may have unexpected behavior, mainly at boat time. 34 00:03:41,650 --> 00:03:47,140 While the pins highlighted in red are not recommended to use as input or output. 35 00:03:47,230 --> 00:03:54,560 Now that general purpose input output pin number zero is, as you can see, OK to use. 36 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 37 00:04:02,830 --> 00:04:06,070 as a pull up input or as output. 38 00:04:06,520 --> 00:04:15,160 It outputs P.W. signal output, but no one can be used as text pin for clear communication or output 39 00:04:15,160 --> 00:04:17,920 when it debug output output. 40 00:04:18,610 --> 00:04:26,080 PIN number two is OK to be used as input or output, and usually it is connected to onboard lid so you 41 00:04:26,080 --> 00:04:33,340 can use it to test a code or to test our function because you don't have to connect extra components 42 00:04:33,490 --> 00:04:35,380 at all that you have built in. 43 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. 44 00:04:42,400 --> 00:04:46,000 It's high output, so it will read one output. 45 00:04:47,630 --> 00:04:55,780 Bin Laden's number four and five are OK to use as Input-Output and PIN number five also outputs P.W. 46 00:04:55,790 --> 00:05:02,370 and signal output bin from six to 11 are connected to the integrated spy flash. 47 00:05:02,870 --> 00:05:13,100 So you can't use them as input or output, but number 12 is OK to use, but both will fail if bold high. 48 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. 49 00:05:18,410 --> 00:05:22,730 Not, and if you are connecting it as output, it's OK. 50 00:05:22,940 --> 00:05:24,350 You don't have any problems. 51 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. 52 00:05:34,790 --> 00:05:45,850 Now, as you can see, same four bins from 17 to 33, while 34, 35, 36 and 39 are input only pens. 53 00:05:45,860 --> 00:05:48,770 You can't you can't use them as output. 54 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 55 00:05:58,910 --> 00:06:00,680 LED, onboard, built and led. 56 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 57 00:06:07,010 --> 00:06:12,140 things if we are making a page with a button to control it via internet. 58 00:06:12,590 --> 00:06:14,660 Now that's it for the pin out. 59 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 60 00:06:23,540 --> 00:06:26,030 about the general purpose input output bins. 61 00:06:26,360 --> 00:06:33,350 But for me, what I need you to know at this point is that we have bins that can be used easily without 62 00:06:33,350 --> 00:06:45,200 any extra attention as input output, which are basically this bins two four, five, 13 to 16 and 17 63 00:06:45,200 --> 00:06:46,040 to thirty three. 64 00:06:46,490 --> 00:06:51,650 And if we want and not only pens, we can use 34, 35, 56 or 39. 65 00:06:52,250 --> 00:06:59,180 Now, if we need extra features, if we need BW, I'm ADC or DSC. 66 00:06:59,390 --> 00:07:06,170 If we need a capacitor enabled bean or BW um pen, we can go on and check this schematic. 67 00:07:06,170 --> 00:07:13,670 And from these bins, you can see that in our case, Jar Purple Spin Number Thirty six can be used as 68 00:07:14,150 --> 00:07:16,340 a DC or these are converters. 69 00:07:17,970 --> 00:07:24,300 As you can see, and it has in what only state you can use this schematic, print it out to refer to 70 00:07:24,300 --> 00:07:26,100 it whenever you need to do something. 71 00:07:26,700 --> 00:07:27,660 Same for here. 72 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 73 00:07:34,650 --> 00:07:40,470 26 can also be used used as central converter automatic converter. 74 00:07:42,230 --> 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 75 00:07:48,350 --> 00:07:50,420 sure that you choose the bin that fits your needs. 76 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, 77 00:07:57,410 --> 00:07:59,540 it's only input only PIN. 78 00:08:00,530 --> 00:08:06,220 And if you want to use, let's say, analog to digital converter, you can't use this bin. 79 00:08:06,230 --> 00:08:14,720 But number 17 because it only supports Syria communication and input output, regular input output or 80 00:08:14,720 --> 00:08:15,950 digital input output. 81 00:08:16,250 --> 00:08:23,780 So before using any bin, take a minute or two to make sure that it supports what you are going to do 82 00:08:24,290 --> 00:08:30,950 and the sensors or the stuff that you are going to connect it to, whether they are analog or digital, 83 00:08:31,400 --> 00:08:36,450 they are input like push button or output like LEDs. 84 00:08:36,919 --> 00:08:47,210 You need to connect the element to the right pin before start recording to avoid having problems in 85 00:08:47,210 --> 00:08:48,020 the future. 86 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 87 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. 88 00:09:01,220 --> 00:09:04,190 I'll be more than happy to help answer all of your concerns. 89 00:09:04,790 --> 00:09:08,150 Thanks for watching this is Ashraf from educational engineering team.
