1 00:00:00,060 --> 00:00:05,460 So first thing that you're going to do here is to declare it right to let it just go ahead. 2 00:00:05,610 --> 00:00:11,460 And we know that are send and receive function work for then you day to go to work. 3 00:00:12,150 --> 00:00:14,520 OK, you could clearly see. 4 00:00:15,540 --> 00:00:17,800 That are you what you sing? 5 00:00:17,890 --> 00:00:21,900 OK, expect the leader to be in, you wait for my right. 6 00:00:22,230 --> 00:00:24,090 We go ahead and we declare. 7 00:00:24,240 --> 00:00:25,290 You wait, right? 8 00:00:25,890 --> 00:00:32,000 And they just name this as the OK, and this will be an array consisting of an 11 elements. 9 00:00:32,580 --> 00:00:35,040 And will also be initializing it to ladies. 10 00:00:35,040 --> 00:00:35,610 Is you? 11 00:00:36,000 --> 00:00:36,540 Hello. 12 00:00:37,650 --> 00:00:43,440 Right, right, so if you count the number of bytes that we have, right, so we have one two three 13 00:00:43,440 --> 00:00:51,690 four five six seven eight nine 10 and 11 eight to 11 character averaging and each character can be represented 14 00:00:51,690 --> 00:00:52,250 within you. 15 00:00:52,490 --> 00:00:54,180 So this could be stored in this area. 16 00:00:54,450 --> 00:00:59,190 So once this is sent, this will serve as the data buffer for us. 17 00:00:59,190 --> 00:01:03,240 Right now, we call you what same function, right? 18 00:01:03,630 --> 00:01:12,440 So it will just be going ahead and then OK, after we perform an initialization we call Sane, right? 19 00:01:12,690 --> 00:01:15,680 First argument is an instance structure, which is you lot. 20 00:01:15,690 --> 00:01:20,700 And then second argument is the pointer to a little before, right? 21 00:01:20,730 --> 00:01:27,840 So here we could just add an embassy and then we could mention that phrase so far zero element of an 22 00:01:27,840 --> 00:01:28,140 finale. 23 00:01:28,230 --> 00:01:28,460 Right. 24 00:01:28,470 --> 00:01:34,950 So this is how we represent the appointed to our data over the other method that you will use this, 25 00:01:34,950 --> 00:01:36,960 you would just mention data, right? 26 00:01:36,960 --> 00:01:42,590 So this will be the second way that you have, which will be providing a correct address for our data 27 00:01:42,600 --> 00:01:43,050 before it. 28 00:01:43,070 --> 00:01:49,800 But the easier we will be using ampersand and then data zero to this basically mean the starting address 29 00:01:49,800 --> 00:01:51,420 of our body weight. 30 00:01:51,420 --> 00:01:57,480 So once this is specified, the next is to specify the number of bytes that we want to transmit. 31 00:01:57,480 --> 00:01:59,820 So here we want to transmit 11 by great. 32 00:02:00,330 --> 00:02:03,240 These are all the argument that you want to provide to. 33 00:02:03,510 --> 00:02:07,650 You are saying function right now, if you just read the description of this function. 34 00:02:09,050 --> 00:02:13,960 Now, this function have a different behavior, considering the different mood, so we are utilizing 35 00:02:13,970 --> 00:02:15,050 a formula here. 36 00:02:15,320 --> 00:02:21,220 So in a poll mode, this function will only send as much data as the can buffer, right? 37 00:02:22,350 --> 00:02:29,890 And if you exceed the size which the people could not hold in in that case, you need to repetitively 38 00:02:29,910 --> 00:02:31,200 run an application, right? 39 00:02:31,680 --> 00:02:35,320 There's also returned the number of bytes actually sent. 40 00:02:35,340 --> 00:02:41,100 So we need to wait till we reach to the value of 11 because we want the same 11 byte. 41 00:02:41,340 --> 00:02:46,320 So how we do that is that it just store this value in one variable. 42 00:02:46,350 --> 00:02:47,670 Now we know that this region is. 43 00:02:47,670 --> 00:02:50,830 So do you let it just name discount hoagie? 44 00:02:51,840 --> 00:02:55,170 And initialize this to a z of so let me just copy this. 45 00:02:56,160 --> 00:03:00,240 OK, declared it over here, and initially it was hit right. 46 00:03:01,190 --> 00:03:08,540 So this variable will keep track of the number of bytes that are actually set right. 47 00:03:08,870 --> 00:03:16,730 So while we could just use while count is not equal to 11. 48 00:03:16,820 --> 00:03:19,910 OK, we could just say we do it here, right? 49 00:03:19,910 --> 00:03:26,150 So we could yet update the value of account and then we'll again be checking whether count is equal 50 00:03:26,240 --> 00:03:27,490 to 11 or not. 51 00:03:27,530 --> 00:03:27,800 Right? 52 00:03:29,090 --> 00:03:36,460 Again, as soon as our count becomes equal to 11, we'll be simply coming out of the what is right, 53 00:03:36,470 --> 00:03:38,480 and in that case, we could just mention. 54 00:03:39,400 --> 00:03:43,900 Data saying successfully, right. 55 00:03:44,350 --> 00:03:49,750 This is a one off movie that we have with us where what we are doing is we are calling you what the 56 00:03:49,750 --> 00:03:50,680 same function. 57 00:03:50,680 --> 00:03:56,170 And then this basically returns the number of bytes which are actually saying and we are waiting for 58 00:03:56,350 --> 00:03:58,570 our count to reach to a value of 11. 59 00:03:58,580 --> 00:04:02,920 So as soon as cowardly just to a value of 11 will be coming out of a while. 60 00:04:03,040 --> 00:04:09,850 And then we'll be sending the string data transmission, our data saying this successful right now here 61 00:04:09,850 --> 00:04:11,890 we need to verify whether. 62 00:04:13,040 --> 00:04:15,560 This returns bye, bye bye. 63 00:04:15,590 --> 00:04:22,520 There it is, with each new bite to whether it returns one or the total bytes that have been sent to 64 00:04:22,520 --> 00:04:23,130 flat rate. 65 00:04:24,020 --> 00:04:28,370 So that could be verified like this, so just go ahead and build an application project. 66 00:04:29,240 --> 00:04:29,570 OK. 67 00:04:29,870 --> 00:04:35,540 And what we're going to do is with each new iteration we'll get with each new iteration, we'll also 68 00:04:35,540 --> 00:04:39,130 be presenting the value of concrete so out. 69 00:04:39,830 --> 00:04:41,840 OK, but since 0d. 70 00:04:42,860 --> 00:04:46,460 And let me just try to bring the value of call, right? 71 00:04:47,770 --> 00:04:50,590 So if you just try to build an application project, no. 72 00:04:51,520 --> 00:04:51,850 OK. 73 00:04:52,210 --> 00:04:56,320 And then debug as launch one hideaway. 74 00:04:57,450 --> 00:05:03,090 So we do not need to do any changes to a serial terminal since we properly configured it to work at 75 00:05:03,090 --> 00:05:04,140 nine six zero zero. 76 00:05:04,560 --> 00:05:08,200 And now you could see you are in, it is successful. 77 00:05:08,230 --> 00:05:10,290 And hello world. 78 00:05:10,350 --> 00:05:11,760 OK, that is what we receive. 79 00:05:12,060 --> 00:05:20,730 Then count is the 11 right and finally data successfully we get so we will be waiting for all the 11 80 00:05:20,730 --> 00:05:24,370 byte to be transmitted and then will be coming out of this way. 81 00:05:24,390 --> 00:05:28,200 Look, and then we just mentioned to sing, OK, successful. 82 00:05:28,770 --> 00:05:30,090 This is what we going to do. 83 00:05:30,120 --> 00:05:32,790 Let it just proceed to build an application project. 84 00:05:33,240 --> 00:05:39,960 And once our build is successful, OK, we could just go ahead to our right this minute, OK, and then 85 00:05:41,010 --> 00:05:43,280 we will just go ahead and relaunch it. 86 00:05:43,350 --> 00:05:44,100 Debug fission. 87 00:05:44,160 --> 00:05:44,430 Right? 88 00:05:44,820 --> 00:05:50,550 So this will automatically reprogram that FPGA and since are white serial terminal is already connected 89 00:05:50,550 --> 00:05:52,680 to the correct portrait as well as correct. 90 00:05:53,020 --> 00:05:55,830 And you just need to go ahead and click on resume button, right? 91 00:05:55,830 --> 00:05:56,990 So you could see you. 92 00:05:57,000 --> 00:05:58,500 What you need is successful. 93 00:05:59,370 --> 00:06:05,400 Then we have to wait and see and successful to be able to send it correctly. 94 00:06:06,210 --> 00:06:11,060 You could just add a new link between Helloworld and data successfully, right? 95 00:06:11,070 --> 00:06:17,280 So here we could just add a new line corrected that is just again the builder application project and 96 00:06:17,280 --> 00:06:20,820 then try to run naked on an FPGA, right? 97 00:06:21,210 --> 00:06:24,210 So again, we will be launching our feedback session. 98 00:06:25,260 --> 00:06:29,810 And then once this is done, will just be clicking on a resume button, wait till you see you are in, 99 00:06:29,820 --> 00:06:35,940 it is successful at lower and then D.D.S. successful road to the Hallowell city that we have in that 100 00:06:36,450 --> 00:06:37,250 data buffer. 101 00:06:37,390 --> 00:06:44,010 So this is how we could proceed, sending the data to the UART terminal right now. 102 00:06:44,010 --> 00:06:49,370 The next target will be to understand how we receive the data from the city.
