1 00:00:00,660 --> 00:00:04,230 Now, let's let's go to the setup function. 2 00:00:05,340 --> 00:00:13,980 The first thing that we need to do is initial overseer of communication, a specific Mod. A simple crate 3 00:00:13,980 --> 00:00:15,180 and I'll do an import. 4 00:00:16,860 --> 00:00:20,340 Then we need to set the timeout for the serial communication. 5 00:00:24,370 --> 00:00:27,790 It will be five hundred milliseconds, so half a second is enough. 6 00:00:28,570 --> 00:00:36,190 Then let's call the setup verify function, just make sure that we have the right name. 7 00:00:37,840 --> 00:00:38,700 This is it up. 8 00:00:38,710 --> 00:00:39,370 Why file? 9 00:00:42,490 --> 00:00:54,940 After that, we need to call the client to server to pass the server parameters and will take an Kutty 10 00:00:56,620 --> 00:01:04,000 server link and NQT port as input. 11 00:01:05,470 --> 00:01:10,960 Then we must call the function reconnect. 12 00:01:13,900 --> 00:01:15,910 Now let's look a file called. 13 00:01:19,600 --> 00:01:25,210 Great, we don't have any issues now we need to define a new function between the setup and lube. 14 00:01:25,840 --> 00:01:28,750 Let's call it populist, so avoid publish. 15 00:01:31,860 --> 00:01:35,160 Syrian data. 16 00:01:39,540 --> 00:01:41,400 Now, this functional take. 17 00:01:44,600 --> 00:01:46,970 Syrian data as input. 18 00:01:51,000 --> 00:01:54,720 And after taking serial death out, import it will. 19 00:01:57,190 --> 00:02:03,340 Make sure that then Kitty said if I was connected using an if statement. 20 00:02:07,330 --> 00:02:11,740 Now inside, they've said statement will, right, if client that connected. 21 00:02:19,240 --> 00:02:21,640 Now, it's not connected. 22 00:02:21,970 --> 00:02:27,100 Call that a connect function to connect it. 23 00:02:27,610 --> 00:02:30,250 Now, once it's connected. 24 00:02:31,240 --> 00:02:36,250 What we should do is publish the data, so publish 25 00:02:39,160 --> 00:02:48,250 the publish will take the MQ 30 Serial Publish channel. 26 00:02:49,570 --> 00:03:00,190 As input will also take the serial data from here, and this is already defined here. 27 00:03:03,300 --> 00:03:04,460 See our published channel. 28 00:03:06,170 --> 00:03:10,070 And you can't change it to your own population. 29 00:03:10,610 --> 00:03:12,410 But for now, let's go back. 30 00:03:13,780 --> 00:03:19,810 OK, now plan to publish the client will publish this. 31 00:03:21,260 --> 00:03:28,190 Syrian death to this channel after making sure that the NQT server is connected. 32 00:03:29,820 --> 00:03:34,680 No, this is the wrong goal from dysfunction inside the void, look, we are going to call this function 33 00:03:35,640 --> 00:03:36,870 so inside the void law? 34 00:03:37,080 --> 00:03:37,950 We will ask. 35 00:03:39,800 --> 00:03:44,570 First, let's call a client that loop function. 36 00:03:47,450 --> 00:03:48,650 Now we will ask if. 37 00:03:51,700 --> 00:04:03,070 That cereal that available is more than zero or above zero means that we have incoming cereal data. 38 00:04:03,730 --> 00:04:09,810 And in that case, if we have incoming cereal, that's what we need to do is take the cereal that aren't 39 00:04:09,820 --> 00:04:14,980 stored in a variable, so will define a character that's called puffer. 40 00:04:17,520 --> 00:04:18,020 Better. 41 00:04:20,150 --> 00:04:21,920 And you can't make it. 42 00:04:25,000 --> 00:04:30,350 This will be an array of characters, and its size will be five hundred ten. 43 00:04:30,400 --> 00:04:34,390 You can turn the site whatever fits your needs. 44 00:04:35,530 --> 00:04:36,610 After doing this? 45 00:04:38,640 --> 00:04:48,180 We are going to use function as our function called Mimi set the level function void limited. 46 00:04:48,180 --> 00:04:55,180 Kobe's the character to the first and characters of the string pointed by the arrow. 47 00:04:55,510 --> 00:04:58,900 Now I will write it down, then I will explain to you. 48 00:04:58,920 --> 00:05:08,630 And while you are using it here, the first thing that you need right here is me sits inside it. 49 00:05:08,940 --> 00:05:13,080 It will take the buffer as input. 50 00:05:14,460 --> 00:05:23,960 And zero then the buffer that of the size, which is 510 now. 51 00:05:24,240 --> 00:05:29,760 What this functional do is the following the first thing that buffer data. 52 00:05:30,300 --> 00:05:33,060 This is the point after the block of memory to fail. 53 00:05:33,270 --> 00:05:36,390 So we need to fill this block of memory with data. 54 00:05:37,080 --> 00:05:40,270 Now the second parameter, which is this number, is zero. 55 00:05:40,830 --> 00:05:42,750 This is the value to be set. 56 00:05:43,170 --> 00:05:49,710 The value is passed as integer, but the function fills the block of memory using the unsigned Charcol 57 00:05:49,710 --> 00:05:50,760 version of the value. 58 00:05:52,230 --> 00:05:57,540 Now we come to the last variable or the last in what which is five hundred and ten. 59 00:05:58,020 --> 00:06:02,370 This is the number of buys to be set to the value, which is basically the size of the array. 60 00:06:04,890 --> 00:06:11,910 This function will return a pointer to the area where buffered data is stored. 61 00:06:13,530 --> 00:06:20,220 Now we need to read that until we see a new line, which is basically what we did not do an accord. 62 00:06:20,580 --> 00:06:21,210 We sing it. 63 00:06:21,220 --> 00:06:22,530 We have send data. 64 00:06:22,710 --> 00:06:25,680 And at the end of each block of death, I think annual line. 65 00:06:26,250 --> 00:06:34,740 So write serial dot read bytes until. 66 00:06:37,740 --> 00:06:40,470 And here are going to other conditions. 67 00:06:41,480 --> 00:06:49,830 First thing is Iran, which is a new line and the data that we read will be stored here in the bazaar 68 00:06:49,830 --> 00:06:54,040 data and the data size. 69 00:06:54,060 --> 00:06:55,440 Let's make it 500. 70 00:06:55,620 --> 00:07:00,540 We already have an array with a size over 500 510. 71 00:07:00,960 --> 00:07:04,500 So five hundred is the same value to be inserted here. 72 00:07:04,890 --> 00:07:13,590 Usually, you have to set a value that's below battery size after this and you need to publish this 73 00:07:13,590 --> 00:07:17,700 data, so publish serial data. 74 00:07:19,410 --> 00:07:21,630 This is the function that we defined here. 75 00:07:25,100 --> 00:07:33,710 And take that that we did receive as input, which is the buffer data, so this function will read the 76 00:07:33,710 --> 00:07:42,710 incoming serial data and sort it here until a new line is sent from the entire ISP. 77 00:07:43,250 --> 00:07:50,870 Then it will send the data to the published serial data function, which takes the data's input. 78 00:07:51,470 --> 00:07:55,160 And this function will make sure that then Kutty server is connected. 79 00:07:55,820 --> 00:08:02,330 After making sure that it's connected, it will publish the data to the NQT serial channel. 80 00:08:03,020 --> 00:08:10,580 And as you can see it, this is a serial that which is the main function of our coding practice here. 81 00:08:10,790 --> 00:08:13,970 Now again, what we have done here. 82 00:08:14,150 --> 00:08:15,170 Let me zoom out. 83 00:08:18,250 --> 00:08:26,440 We have created defined some variables, and we have used the computer to library the wildfire library, 84 00:08:27,220 --> 00:08:33,010 set up wildfire to make sure that we are connecting or we are connected to our Wi-Fi network and we 85 00:08:33,010 --> 00:08:33,730 are online. 86 00:08:34,300 --> 00:08:41,980 That connect function is to make sure that we are connected to the NQT server and we have a set function 87 00:08:42,610 --> 00:08:48,340 where we have connect to Wi-Fi and to that community server. 88 00:08:49,360 --> 00:08:54,370 Then we have the loop, which will make sure that we are all. 89 00:08:54,370 --> 00:08:55,960 We have incoming serial data. 90 00:08:57,790 --> 00:09:04,150 And it will store the incoming serial data inside this variable before death, which is basically an 91 00:09:04,150 --> 00:09:11,140 idea of character and will send it to the public serial data function, which is this one first. 92 00:09:11,530 --> 00:09:14,830 We will make sure that we are connected to the security server. 93 00:09:15,340 --> 00:09:20,440 Then we will publish the data to this channel that we are defined here. 94 00:09:21,700 --> 00:09:26,810 So this is our main coding practice for DSP 32. 95 00:09:27,600 --> 00:09:32,860 The next lesson we are going to sort this out and make sure that it's working just fine. 96 00:09:33,550 --> 00:09:39,160 If you have any question regarding any of these lines, please ask and get you on their board now just 97 00:09:39,160 --> 00:09:40,790 to make sure that you don't have any errors. 98 00:09:40,810 --> 00:09:44,140 Let's verify our code one more time. 99 00:09:45,390 --> 00:09:51,870 OK, now we have a new, as you can see, Cyril, that was not declared, it's here. 100 00:09:52,260 --> 00:09:57,030 So we have a spelling error, but if I gain. 101 00:09:59,950 --> 00:10:02,050 Dan, combining without any errors. 102 00:10:02,380 --> 00:10:02,980 That's it. 103 00:10:03,280 --> 00:10:11,030 Now we might have to change the values for our Wi-Fi network name and password and for that and use 104 00:10:11,050 --> 00:10:18,100 the username and password and the channel all of the server links, depending on all needs. 105 00:10:18,130 --> 00:10:26,890 Now, if you are using your own API, you can simply send the serial data to your own API using JSON 106 00:10:26,890 --> 00:10:33,040 coding or any other method that fits your new, you know, your needs. 107 00:10:33,070 --> 00:10:35,650 But for now, I'm using them here to teach server. 108 00:10:35,650 --> 00:10:38,590 So this is the coding practice for this server. 109 00:10:39,070 --> 00:10:41,620 It's a very well-known and widely used one. 110 00:10:42,130 --> 00:10:50,050 So I will change that Wi-Fi network values and their username and password values with mine. 111 00:10:50,380 --> 00:10:52,810 Then we will test this called out. 112 00:10:53,200 --> 00:10:54,400 Thanks for watching this lesson. 113 00:10:54,550 --> 00:10:57,400 This is Ashraf from educational engineering team.
