1 00:00:01,200 --> 00:00:02,520 Hello, welcome back. 2 00:00:03,270 --> 00:00:11,400 So in this first lesson or in this first practical lesson, we're going to see how to create tasks. 3 00:00:12,350 --> 00:00:19,100 In our free ARTUS real time system, I'm going to create a new project by coming over here, project 4 00:00:19,100 --> 00:00:22,480 new estimate, 32 projects like this over here. 5 00:00:27,220 --> 00:00:33,490 I'll select my board over here, I'll search ASTM 32 for one one. 6 00:00:34,610 --> 00:00:41,630 I'm using DSM three to four one one nucleo, so I'll select this over here and then I'll click next. 7 00:00:43,460 --> 00:00:46,400 Next, it's down here, it's out of the screen. 8 00:00:48,840 --> 00:00:57,960 This is next click next over here and then I'll give this project a name, I'll call it task creation. 9 00:01:06,990 --> 00:01:13,740 And then over here to get to prototype, I'm going to keep it at SDM 32 Cube because we need to go to 10 00:01:13,740 --> 00:01:20,040 SDM 32 Cube to include our Toscano and also to include the Toynbee's. 11 00:01:20,490 --> 00:01:22,310 We could just use empty bay. 12 00:01:22,320 --> 00:01:26,880 If we use empty, we would have to manually include the frittatas files. 13 00:01:27,450 --> 00:01:31,170 We have to go and download the files and manually include them to our path. 14 00:01:31,530 --> 00:01:33,900 So I'll use them to 32 over here. 15 00:01:34,800 --> 00:01:36,390 OK, so I'll click next. 16 00:01:37,420 --> 00:01:38,830 And then I'll click finish. 17 00:01:41,080 --> 00:01:47,050 So it says device configuration to ED associated with device configuration to perspective, do you want 18 00:01:47,050 --> 00:01:49,200 to open this perspective now? 19 00:01:49,300 --> 00:01:50,110 I would say yes. 20 00:01:54,700 --> 00:02:03,040 So this is the the Cuba mix perspective, so I should mention we're not going to be creating our artists 21 00:02:03,040 --> 00:02:10,480 using Cuba mics, we simply need to include the middleware and then select the time we want to use as 22 00:02:10,480 --> 00:02:11,470 the artists can. 23 00:02:11,620 --> 00:02:12,280 Time, Time-Based. 24 00:02:13,200 --> 00:02:18,510 And then we're going to go and quote the task creation to semaphore creation, we're going to quote 25 00:02:18,510 --> 00:02:19,800 all of that from scratch. 26 00:02:20,160 --> 00:02:28,800 And then when we get to where we've learnt all the various APIs of the arm of the Artosis, then then 27 00:02:28,800 --> 00:02:29,820 we'll learn how to. 28 00:02:30,940 --> 00:02:37,560 Enable that use in Cuba without writing code and then learn how to apply something known as the Simms's 29 00:02:37,560 --> 00:02:42,390 ARTUS APIs, but for now we simply going to write the better free ARTUS. 30 00:02:42,390 --> 00:02:44,370 We're going to use the free Arktos functions. 31 00:02:44,790 --> 00:02:51,290 There's a layer on top of free Archos known as Simms's artists, which wraps around a free ARTUS functions. 32 00:02:51,540 --> 00:02:53,700 We shall see how to use those later. 33 00:02:54,930 --> 00:02:57,570 So this is how, Chip, it's giving us an image of it. 34 00:02:58,980 --> 00:03:00,380 I'm going to come over here. 35 00:03:01,590 --> 00:03:07,710 Middleware, drop this and then I'll select free artists over here, and then, as you can see, it's 36 00:03:07,710 --> 00:03:11,910 asking what I want to use Simms's V1 or Simms's V. to isolate Simms's V2. 37 00:03:12,630 --> 00:03:13,020 Right. 38 00:03:13,500 --> 00:03:15,720 So after we've selected. 39 00:03:18,560 --> 00:03:24,680 This this fall opens all this bit here, open scientific parameters, this allows us to configure our 40 00:03:24,680 --> 00:03:25,820 artist parameters. 41 00:03:26,000 --> 00:03:32,720 The version of free artists used here is the ten point two, ten point two point one, and then it's 42 00:03:32,720 --> 00:03:40,190 telling us the system clock, this is our take rate and then maximum name length, we can give our tasks 43 00:03:40,940 --> 00:03:41,590 names. 44 00:03:41,600 --> 00:03:47,780 And this is the number of characters that the name can have, things like that. 45 00:03:47,960 --> 00:03:53,990 So all of this, we would see how to configure them manually so we wouldn't do any configurations here. 46 00:03:55,250 --> 00:04:03,050 OK, let's go other topics here, let's see and when we create this, it automatically creates a task 47 00:04:03,050 --> 00:04:03,490 for us. 48 00:04:03,500 --> 00:04:06,500 So there is this difficult task that is created. 49 00:04:07,880 --> 00:04:10,530 Right, we cannot remove it, so I'll keep it. 50 00:04:10,640 --> 00:04:15,650 I I'll just leave it like this, but when we go to our code, we delete it and start writing the tasks 51 00:04:15,890 --> 00:04:16,580 from scratch. 52 00:04:16,940 --> 00:04:19,250 OK, so once you've included this. 53 00:04:21,120 --> 00:04:24,360 Once you've included the middle where? 54 00:04:26,120 --> 00:04:28,790 Then all you have to do is select your time. 55 00:04:28,930 --> 00:04:35,780 So what we did, just to recap, we came to free toes here on the middle were and then we selected Simms's 56 00:04:35,780 --> 00:04:36,260 V2 two. 57 00:04:36,270 --> 00:04:37,680 That's all we've done so far. 58 00:04:38,300 --> 00:04:40,640 So once that is done, we go into. 59 00:04:43,110 --> 00:04:45,450 We're going to come over here to system call. 60 00:04:46,600 --> 00:04:53,740 And then under system here and a time this year, we're not going to use system, it's recommended to 61 00:04:53,740 --> 00:04:55,090 use a different time base. 62 00:04:55,330 --> 00:04:58,060 So I use time as one as the time base. 63 00:05:00,210 --> 00:05:08,100 OK, so once that is done, one other thing I'll do over here is enable our Ewart's so that we can use 64 00:05:08,100 --> 00:05:15,330 the you out to debug our artists so that you are just connected to a one and two. 65 00:05:15,840 --> 00:05:22,380 One way to enable the you are to module is to simply come to connectivity and then you go to use that 66 00:05:22,380 --> 00:05:25,500 to you are to use its means. 67 00:05:25,500 --> 00:05:29,070 The same thing it's written you Satya because you. 68 00:05:29,070 --> 00:05:37,050 S stands for Universal Synchronoss asynchronous receiver transmitter because we often use just the asynchronous 69 00:05:37,050 --> 00:05:37,440 bits. 70 00:05:37,470 --> 00:05:40,040 We often see just you out without. 71 00:05:40,070 --> 00:05:40,530 Yes. 72 00:05:40,890 --> 00:05:42,060 So it's the same what you. 73 00:05:43,100 --> 00:05:50,260 So I just clicked here, USA to this is the one which is connected to our USB port, our come to mode 74 00:05:50,270 --> 00:05:56,900 over here and then our select asynchronous mode, like I mentioned earlier, and I'll leave everything 75 00:05:56,900 --> 00:05:57,590 here the same. 76 00:05:59,060 --> 00:06:01,520 Right, and then I'll close this. 77 00:06:03,740 --> 00:06:04,370 And then. 78 00:06:08,760 --> 00:06:12,990 Click here to generate the code, this this symbol here. 79 00:06:14,830 --> 00:06:21,150 This auction can be associated with a C slash C++ perspective, do you want to open this perspective? 80 00:06:21,550 --> 00:06:22,440 I'll say yes. 81 00:06:22,960 --> 00:06:28,950 So whenever the perspective is about to switch, we receive a message, OK? 82 00:06:37,800 --> 00:06:40,710 So it says device configuration to update an. 83 00:06:43,000 --> 00:06:44,130 OK, here we go. 84 00:06:48,380 --> 00:06:52,560 So our project is here in the corner here. 85 00:06:52,850 --> 00:06:53,450 The target. 86 00:06:54,030 --> 00:06:54,580 OK. 87 00:06:59,740 --> 00:07:01,300 Let me switch the perspective. 88 00:07:02,310 --> 00:07:06,540 OK, so what are we going to do is I'm going to come to a window here and come to Perspective's. 89 00:07:07,500 --> 00:07:10,050 And then open perspective. 90 00:07:12,390 --> 00:07:13,860 Also, research perspective. 91 00:07:15,110 --> 00:07:16,310 Research over here. 92 00:07:16,430 --> 00:07:22,520 OK, so this the one we are all used to when it comes to clips, you have your project explorer here. 93 00:07:23,600 --> 00:07:25,270 OK, so this is our project. 94 00:07:25,280 --> 00:07:27,140 It's collected all the files, like I said. 95 00:07:27,140 --> 00:07:29,360 Well, we were interested in the. 96 00:07:31,100 --> 00:07:39,320 The path to this project, Mindiola, but Cuba allows us just to click and include. 97 00:07:40,180 --> 00:07:47,860 OK, so before we continue, I'm going to go ahead and increase the font size, I'll come to window 98 00:07:47,890 --> 00:07:49,150 preferences over here. 99 00:07:51,190 --> 00:07:51,790 And then. 100 00:07:56,430 --> 00:07:57,390 Come to general. 101 00:08:01,010 --> 00:08:06,410 Or drop down, general, like this, and then I can come to editors over here. 102 00:08:08,810 --> 00:08:10,760 Let's see Pierrot's. 103 00:08:17,170 --> 00:08:19,510 So, General, over here, editors. 104 00:08:20,540 --> 00:08:28,280 I'll drop down text editors or I can simply open text editors, so general editors, text editors, 105 00:08:28,460 --> 00:08:29,570 colors and phones. 106 00:08:30,520 --> 00:08:34,300 And then this opens and then I click here to edit. 107 00:08:36,140 --> 00:08:40,010 And then over here, I could choose 14, I'll say, OK. 108 00:08:41,730 --> 00:08:42,300 PLI. 109 00:08:45,760 --> 00:08:47,230 That's 14 look big enough. 110 00:08:50,130 --> 00:08:53,340 OK, so I'll close now applying close. 111 00:08:56,100 --> 00:09:02,370 OK, so this is what we have and then so to simplify what we've got here, I'm going to clean. 112 00:09:03,840 --> 00:09:11,850 I'm going to clean everything right, except the the time these and the include, so. 113 00:09:14,610 --> 00:09:21,540 No comment, I'm going to clean this right at this stage, you wouldn't know what this means. 114 00:09:21,930 --> 00:09:23,240 So this is clean as well. 115 00:09:26,240 --> 00:09:27,170 This one to. 116 00:09:33,410 --> 00:09:44,160 This so I'm simply removing the comments so that you see how simple the whole thing is with the comments. 117 00:09:44,540 --> 00:09:46,130 It's hard to know which is which. 118 00:09:48,060 --> 00:09:49,380 OK, so clean this. 119 00:09:53,320 --> 00:09:54,040 Clean this. 120 00:09:56,500 --> 00:09:57,910 Still cleanin comments. 121 00:10:01,780 --> 00:10:06,770 OK, OK, so of sufficiently Klina comments, let's see what we have left. 122 00:10:07,540 --> 00:10:11,020 OK, so this is our main function. 123 00:10:11,020 --> 00:10:14,270 Our main started by calling this function in a hole in it. 124 00:10:14,710 --> 00:10:17,880 This means hardware obstruction. 125 00:10:18,130 --> 00:10:19,690 That's what will host for in it. 126 00:10:19,870 --> 00:10:22,900 And this initializes some hardware stuff. 127 00:10:23,230 --> 00:10:26,610 When you are using Cuba, it's always comes with a hole in it. 128 00:10:27,160 --> 00:10:32,120 We can implement the content of this function ourselves, but that's not the purpose of this course. 129 00:10:32,500 --> 00:10:39,370 So after hole in its hole in it would initialize what time I should be used for our delay function, 130 00:10:39,370 --> 00:10:47,290 for instance, because we can see how delay and gets the amount of delay that we pass as argument to 131 00:10:47,290 --> 00:10:48,970 that particular hole delay function. 132 00:10:49,210 --> 00:10:50,980 So HOLLIN it deals with that stuff. 133 00:10:50,980 --> 00:10:56,470 It would sort it out for us and then their system configured system clock config and this configures 134 00:10:56,470 --> 00:11:04,600 the system clock the clock for the the the main system clock as well as the clock for the various buses. 135 00:11:04,960 --> 00:11:13,300 You should know that our microcontroller has multiple buses and is from these buses that the various 136 00:11:13,300 --> 00:11:15,790 peripherals and modules Gadhia Clock. 137 00:11:16,210 --> 00:11:20,960 So you would have a situation where you have two peripherals with different clock. 138 00:11:21,250 --> 00:11:27,880 The reason why you can have two peripherals and they have different clocks is because they're cerebus 139 00:11:27,880 --> 00:11:29,860 the the on separate buses. 140 00:11:30,820 --> 00:11:36,320 And even apart from that, we can apply a preschooler to each peripheral to reduce its clock. 141 00:11:36,760 --> 00:11:44,080 So anyway, the system clock on fiqh allows us to configure the systems clock as well as the clock for 142 00:11:44,080 --> 00:11:46,560 the various buses and the microcontroller. 143 00:11:46,810 --> 00:11:47,860 And we shall see those. 144 00:11:48,040 --> 00:11:49,660 We shall talk about them when we need them. 145 00:11:49,880 --> 00:11:55,030 So we have APV, one bus, EPB to bus each bus, things like this. 146 00:11:55,030 --> 00:11:57,370 And you can find these names in the comments here. 147 00:11:57,670 --> 00:11:59,550 But that is not the purpose here. 148 00:11:59,740 --> 00:12:01,420 So that's what system config does. 149 00:12:01,450 --> 00:12:02,950 That's what it's done here. 150 00:12:03,220 --> 00:12:06,580 So this system config function has been included here for us. 151 00:12:07,860 --> 00:12:11,160 Does a system config, as you can see over here, right? 152 00:12:11,370 --> 00:12:13,020 There isn't much with this. 153 00:12:13,350 --> 00:12:21,870 So then then we have to use that to you, its function, because we enabled the user to then this was 154 00:12:21,870 --> 00:12:25,150 included and we can find the implementation of this function down here. 155 00:12:25,500 --> 00:12:33,300 So basically, user two was configured to run out one hundred and one hundred and fifteen thousand two 156 00:12:33,300 --> 00:12:37,320 hundred point rates than other configurations were included. 157 00:12:37,500 --> 00:12:40,730 OK, then we have a what are you in it? 158 00:12:40,740 --> 00:12:43,650 And inside this GPL you in it which is the. 159 00:12:44,550 --> 00:12:49,830 The third function or yeah, the third function called here we simply enabling access. 160 00:12:51,240 --> 00:13:00,100 To the sports, you put a remember GPA, you e is where are you at Pinsker are connected to Impey three. 161 00:13:00,360 --> 00:13:05,370 So in order to be able to use them, in order to be able to use that, you are to clock access needs 162 00:13:05,370 --> 00:13:08,790 to be enabled to these pins and thus the cingulate. 163 00:13:09,270 --> 00:13:10,290 That's the thing our. 164 00:13:12,900 --> 00:13:19,940 And interesting for us, and then after that, we have our always canno initialise, and this is Colonel 165 00:13:19,960 --> 00:13:22,180 Initialise comes with. 166 00:13:23,340 --> 00:13:31,170 Simms's artus remember free artosis separate from Simms's Artus free Archos as a real time canno built 167 00:13:31,170 --> 00:13:40,160 by one company, Simms's artists, is a standardization that is applied on top of free artists to make 168 00:13:40,170 --> 00:13:44,910 the free Arktos functions look similar to other Arktos functions. 169 00:13:46,170 --> 00:13:51,870 What I mean by this is with this way of writing, the function always threaten you. 170 00:13:52,940 --> 00:14:00,320 If I'm using a different artists such as call artists, I'll write exactly the same thing and I'll be 171 00:14:00,320 --> 00:14:04,970 able to create a new a new thread dysfunction, always thread new. 172 00:14:05,480 --> 00:14:13,220 If I wanted to create a new thread in a separate Real-Time operating system like Call Art, which is 173 00:14:13,220 --> 00:14:15,590 another popular operating system out there. 174 00:14:15,980 --> 00:14:23,840 If I write this function, it would work the same way as if I write it using free artists. 175 00:14:23,990 --> 00:14:28,640 And what allows this standardization is Simms's artists. 176 00:14:29,210 --> 00:14:32,270 So Simms's Artosis a wrapper around. 177 00:14:33,460 --> 00:14:36,590 And already exist in real time operating system. 178 00:14:37,120 --> 00:14:42,700 So in these initial lessons, like I said, we're not going to be working with are just going to use 179 00:14:42,700 --> 00:14:45,100 the actual functions of three artists. 180 00:14:45,280 --> 00:14:50,220 And then later on we shall see how to use the Simms's ARTUS APIs. 181 00:14:51,580 --> 00:14:57,090 So what I'm going to do is I'm going to delete the out stuff or delete this year. 182 00:14:58,000 --> 00:15:04,360 And yeah, so now we simply have our hardware initialization hole in its system. 183 00:15:04,360 --> 00:15:05,980 Clock Jhpiego. 184 00:15:06,850 --> 00:15:09,010 You oughton it and then let's see. 185 00:15:10,170 --> 00:15:17,310 So when we in Cuba, we saw that there was a difficult task that was there and we couldn't delete it. 186 00:15:17,340 --> 00:15:18,780 So this is the difficult task. 187 00:15:19,050 --> 00:15:22,870 Remember, a task as a task is like a main function. 188 00:15:23,640 --> 00:15:26,610 So you see it has an infinite loop here. 189 00:15:28,420 --> 00:15:32,560 Whenever you see an infinite loop inside a function, that function is is a task. 190 00:15:33,370 --> 00:15:34,780 OK, so I'll delete this. 191 00:15:35,980 --> 00:15:37,510 We don't need this as well. 192 00:15:37,540 --> 00:15:41,490 So this is our time because remember, we select a time we want to be out. 193 00:15:41,490 --> 00:15:44,830 What time is this code was generated because of that? 194 00:15:45,550 --> 00:15:53,350 So this is a short overview of what we collected because we've deleted this task, remove its prototype 195 00:15:53,350 --> 00:15:53,890 from here. 196 00:15:55,370 --> 00:15:59,900 So what we have left is simply our hardware initialization we initialised. 197 00:16:01,160 --> 00:16:06,920 Just the peripherals we use and there is no art or stuff here, no, there's nothing to do with our 198 00:16:07,140 --> 00:16:14,540 here, we've included Simms's or storage and then there's me each and inside me and what we may have 199 00:16:14,540 --> 00:16:16,240 some of our favorite artists. 200 00:16:16,820 --> 00:16:18,710 Let's go inside me agency. 201 00:16:18,860 --> 00:16:20,660 I'll double click this right click. 202 00:16:21,760 --> 00:16:24,780 I'll say open declaration, OK? 203 00:16:24,950 --> 00:16:33,580 So does this mean that each inside mean that each we have estimated to hold each OK, so our free Arktos 204 00:16:33,580 --> 00:16:35,530 head of ours will be included here. 205 00:16:36,620 --> 00:16:40,790 Then we can click here, Simms's, who is. 206 00:16:41,870 --> 00:16:43,760 Knowledge open declaration here. 207 00:16:46,910 --> 00:16:47,520 Let's see. 208 00:16:47,590 --> 00:16:55,100 OK, so this in here, we have free after storage, so our free artosis included here together with 209 00:16:55,100 --> 00:17:03,680 certain definitions of the CMC Sports Apeace, OK, so free actors have all this included for us. 210 00:17:05,500 --> 00:17:05,860 Right. 211 00:17:05,890 --> 00:17:08,350 So let's build and see we've cleaned. 212 00:17:09,750 --> 00:17:11,550 Let's do it and see what we have. 213 00:17:14,180 --> 00:17:14,900 It's building. 214 00:17:19,740 --> 00:17:22,380 So it's built successfully writes. 215 00:17:24,560 --> 00:17:29,670 OK, so we brought you out here to be used as a tool. 216 00:17:29,870 --> 00:17:38,270 So we're going to be we're going to be using the you ought to print various debug information, as well 217 00:17:38,270 --> 00:17:41,030 as feedback that we require from our various tasks. 218 00:17:41,270 --> 00:17:47,660 To do this, we need to install a zero program on our computer to be able to receive or to display what 219 00:17:47,660 --> 00:17:52,330 is received from the popular ones, include terrorism or Real-Time. 220 00:17:52,340 --> 00:17:54,520 If you have any one of these, you can. 221 00:17:55,250 --> 00:17:55,760 You can. 222 00:17:56,860 --> 00:18:02,080 You can keep them without downloading a new one, but for those of you who do not have any serious program, 223 00:18:02,320 --> 00:18:03,900 we're going to download real time. 224 00:18:03,910 --> 00:18:05,710 So you simply open your browser. 225 00:18:07,440 --> 00:18:16,770 And then you're going to search real time over here like this, and then you can just click. 226 00:18:18,250 --> 00:18:19,750 You can click one of these links. 227 00:18:20,930 --> 00:18:23,450 I'll click this first one to see if we get it. 228 00:18:28,190 --> 00:18:28,880 It's open in. 229 00:18:30,540 --> 00:18:33,360 I've read this before, so I just click to accept you over here. 230 00:18:35,100 --> 00:18:38,150 And once this is done, click download over here. 231 00:18:40,150 --> 00:18:42,550 And it says your download will start shortly. 232 00:18:44,660 --> 00:18:49,550 And as you can see over here, it's finished downloading, so click over here to open it. 233 00:18:50,730 --> 00:18:55,740 I say, yes, I've installed this before, by the way, so I see next over here. 234 00:18:56,740 --> 00:18:57,250 Next. 235 00:18:58,410 --> 00:18:58,980 Next. 236 00:19:00,090 --> 00:19:02,700 There needs to this is a very straightforward was it. 237 00:19:03,600 --> 00:19:10,830 OK, so Registar Real-Time Automation Server, I don't want to do any of this, um, I don't want to 238 00:19:10,830 --> 00:19:13,620 open read me, so just finish after this. 239 00:19:14,360 --> 00:19:16,540 OK, so we have real time. 240 00:19:17,340 --> 00:19:17,720 Right. 241 00:19:17,970 --> 00:19:19,950 So once that is done, there's one other thing. 242 00:19:20,100 --> 00:19:23,460 OK, let's let's check before we do this other thing. 243 00:19:24,120 --> 00:19:24,690 Um. 244 00:19:27,450 --> 00:19:35,220 So you are on itself, doesn't work with printf in order to use the printf, we have to retarget it. 245 00:19:35,730 --> 00:19:44,240 So we have to implement the Pusha function, which char or put character is a function in C language. 246 00:19:44,460 --> 00:19:48,950 So we have to perform our own implementation of it in order to be able to use printf. 247 00:19:49,260 --> 00:19:58,500 So we have to write and underscore, underscore, io underscore, underscore, put H.E.R over here and 248 00:19:58,500 --> 00:20:01,800 then this would take into a segment. 249 00:20:03,270 --> 00:20:09,180 OK, so there's the function Prototyp so down here we can implement the function. 250 00:20:09,180 --> 00:20:09,930 I'll copy this. 251 00:20:10,860 --> 00:20:14,640 And I implement a function over here, OK? 252 00:20:16,560 --> 00:20:21,130 What we want to do is call the the you are to transmit function. 253 00:20:21,720 --> 00:20:30,870 So if we were if we wanted to transmit a character, we would do whole underscore you at underscore 254 00:20:31,470 --> 00:20:32,160 transmit. 255 00:20:35,500 --> 00:20:42,200 And the first document of this is the address of our Ewart's instance one, this one here. 256 00:20:43,060 --> 00:20:46,270 So this the first document where we. 257 00:20:48,840 --> 00:20:52,590 Piece this over here and then we put the numbers on sign here like this. 258 00:20:54,340 --> 00:20:57,430 So if you want to know more about this function you just highlighted. 259 00:20:59,220 --> 00:21:05,910 We can highlight this and then we'll be told more about it, since an amount of data in blocking mode 260 00:21:06,180 --> 00:21:08,210 when you watch is not disabled. 261 00:21:08,580 --> 00:21:11,430 So it tells us from one parent to parent to me. 262 00:21:13,120 --> 00:21:15,580 There is the first problem here says. 263 00:21:16,690 --> 00:21:22,810 Point out to you what type of structure and then the second paragraph is pointed to the data above the 264 00:21:22,810 --> 00:21:28,510 third parameter, which is the third parameter or argument is the amount of data element. 265 00:21:28,840 --> 00:21:32,170 And then the last argument or parameter is the time out. 266 00:21:32,860 --> 00:21:33,210 Right. 267 00:21:33,640 --> 00:21:34,030 So. 268 00:21:35,250 --> 00:21:41,030 Ampersand right here and then next we. 269 00:21:43,310 --> 00:21:46,670 We see you in St.. 270 00:21:48,760 --> 00:21:51,760 We typecast this argument here to you in eight. 271 00:21:53,120 --> 00:22:01,070 And I to point up the name of the argument to see besides this one and then time out, I'm going to 272 00:22:01,070 --> 00:22:02,720 see your over here. 273 00:22:03,200 --> 00:22:06,110 I'm going to see if if like this. 274 00:22:07,570 --> 00:22:09,010 OK, so now. 275 00:22:11,020 --> 00:22:15,640 Let's see, I don't want to use Pranav and I just want to transmit a character, I could have done this. 276 00:22:18,970 --> 00:22:22,350 I could have just pasted this in here and then I'll see, OK? 277 00:22:24,170 --> 00:22:34,040 Oh, see, message, I sent message messages, an array of size one and message has each in its. 278 00:22:35,950 --> 00:22:43,540 And over here, I'll pass messages, arguments, I could see this, OK, and then let's build I'll build 279 00:22:43,540 --> 00:22:43,840 this. 280 00:22:44,870 --> 00:22:48,890 But to show you what we would have to do without doing this. 281 00:22:50,140 --> 00:22:50,710 Let's see. 282 00:22:53,650 --> 00:22:55,810 There's an issue here, control reaches. 283 00:22:56,760 --> 00:23:02,520 And then over here, it says, OK, so we forgot to return. 284 00:23:02,550 --> 00:23:04,340 Remember, this has to return on end. 285 00:23:04,500 --> 00:23:07,920 So do the implementation of gutshot is first. 286 00:23:08,280 --> 00:23:13,860 Do you transmit the documents and then to return the documents? 287 00:23:14,850 --> 00:23:18,050 OK, so I'll do it again. 288 00:23:21,970 --> 00:23:24,880 OK, this is we've got to warning's. 289 00:23:31,170 --> 00:23:37,710 Right over here, we just put the brackets around the scoreboard, so we click to build. 290 00:23:39,140 --> 00:23:41,090 And it's looking good what we want to do. 291 00:23:41,300 --> 00:23:47,390 I want to comment on this implementation that we've just done, so you just hold on control and then 292 00:23:47,390 --> 00:23:55,910 you press the button or you can highlight it and come to source and then select comment over here. 293 00:23:58,000 --> 00:23:59,620 Block comment or Tokyo, your comments. 294 00:23:59,810 --> 00:24:01,990 OK, so let's see. 295 00:24:03,060 --> 00:24:09,880 We don't have anything to do with posture at the moment, and we've just initialized the US. 296 00:24:11,340 --> 00:24:12,180 Click here to build. 297 00:24:13,800 --> 00:24:21,580 And we are transmitting your transmitting this, OK, so to flush onto our board, you have to click 298 00:24:21,580 --> 00:24:23,550 here, click over here, debark. 299 00:24:27,140 --> 00:24:29,090 And then I'll say, OK. 300 00:24:34,290 --> 00:24:37,860 It's opening in the northeast, which. 301 00:24:39,980 --> 00:24:41,690 And then I'm going to open real time. 302 00:24:51,610 --> 00:24:52,220 Here we are. 303 00:24:52,820 --> 00:25:00,370 So come on the porch over here, then I'll select the port, the port for my borders, Port 16, I select 304 00:25:00,370 --> 00:25:01,210 this over here. 305 00:25:01,630 --> 00:25:06,460 And then the boat, as we saw, is one one five two zero zero. 306 00:25:07,400 --> 00:25:14,960 So come over here then, once all of this is done or click open ports, OK, and then I'm going to click 307 00:25:15,200 --> 00:25:18,560 to at this stage, our program is frozen. 308 00:25:18,830 --> 00:25:23,810 Whenever you come to the debug view the program, you or your family would restart and then it will 309 00:25:23,810 --> 00:25:24,380 be frozen. 310 00:25:24,380 --> 00:25:26,780 You have to click play to let it play. 311 00:25:27,050 --> 00:25:32,690 So I click play over here and I can see we are transmitting our h h h h h ok. 312 00:25:34,140 --> 00:25:34,620 Stop. 313 00:25:35,640 --> 00:25:36,100 Right. 314 00:25:36,390 --> 00:25:39,730 So then the question is, what if we want to transmit a sentence? 315 00:25:39,750 --> 00:25:44,420 Are we going to implement character by character? 316 00:25:45,030 --> 00:25:47,340 Or maybe we keep this sentence in a buffer? 317 00:25:47,340 --> 00:25:52,710 We can keep the sentence in a buffer and then just make sure the size is the size of the buffer and 318 00:25:52,710 --> 00:25:53,910 we'll be able to transmit it. 319 00:25:54,390 --> 00:26:01,310 But a more effective way is to use our printf, which we are used to from C language. 320 00:26:01,560 --> 00:26:03,600 So I'm going to uncommented this. 321 00:26:04,110 --> 00:26:07,390 I'm going to delete this, then delete this as well. 322 00:26:07,440 --> 00:26:08,580 This was just a test. 323 00:26:09,000 --> 00:26:12,750 And then over here or Cuccia, I'm going to uncommented as well. 324 00:26:13,620 --> 00:26:18,090 OK, so once we've done this now, I'll come over here. 325 00:26:20,130 --> 00:26:23,400 Right, print of a siff, I mean, see language. 326 00:26:26,760 --> 00:26:33,160 Hello from SDM, then two, and then I'll see you lying carriage return over here and then I'll put 327 00:26:33,160 --> 00:26:36,000 this over here, click over here to build. 328 00:26:39,360 --> 00:26:41,010 So we've got a warning. 329 00:26:42,730 --> 00:26:49,140 OK, the reason we would have a warning is in order to use Pranav, if you have to include Witheridge, 330 00:26:49,540 --> 00:26:57,410 so I'll come over here and see include SDD by the ridge. 331 00:26:59,060 --> 00:27:01,010 OK, click over here to build. 332 00:27:04,030 --> 00:27:05,300 No, no warning. 333 00:27:06,010 --> 00:27:08,080 OK, click debug. 334 00:27:13,850 --> 00:27:14,360 Switch. 335 00:27:19,310 --> 00:27:23,540 OK, and then I'll click play, then I'm going to go to real team. 336 00:27:24,790 --> 00:27:25,730 Going to clear this. 337 00:27:27,720 --> 00:27:29,520 Yes, you can put. 338 00:27:35,030 --> 00:27:37,190 Nothing is showing us stop this. 339 00:27:41,310 --> 00:27:44,130 So let's inspect our targets code again. 340 00:27:44,640 --> 00:27:48,300 This is the prototype and the implementation. 341 00:27:51,730 --> 00:27:58,210 OK, so over here, it's supposed to be under school on the school aisle and then a single underscore 342 00:27:58,240 --> 00:28:05,170 before
