WEBVTT 00:00.210 --> 00:06.850 Now that you can print some text with the LCD, let's actually play a little bit more with the functionalities 00:06.870 --> 00:11.030 of this LCD screen and actually use the cursor. 00:11.040 --> 00:17.460 So I will show you how to print text to print numbers in different places of the LCD because you have 00:17.520 --> 00:26.880 16 by two, OK, which means that you can print text our character anywhere in these 16 by two matrix 00:26.880 --> 00:28.650 here on the LCD screen. 00:28.860 --> 00:35.580 So first, let's try to understand what happens when you do actually print why this is printed on the 00:35.580 --> 00:36.640 top left. 00:37.170 --> 00:47.400 OK, there is a function actually that you can call is L.C that sets Chiuso should arrange and you can 00:47.400 --> 00:52.050 set the course also the sort of where it's going to print the text. 00:52.500 --> 00:56.210 And the first parameter is the number of the column. 00:56.240 --> 00:59.130 So you can go from zero to 15. 00:59.640 --> 01:06.700 OK, so you have 16 seconds from zero to 15, let's say zero, and then the number of the line. 01:06.730 --> 01:09.660 So line zero, line one. 01:09.810 --> 01:13.830 OK, there are two lines, so let's put zero and zero. 01:14.730 --> 01:21.750 So when you set the cursor to zero and zero, that is the default behavior and that's what you are going 01:21.750 --> 01:23.520 to get with this. 01:23.550 --> 01:29.370 OK, so when you don't put this line, it's just like you have said the cursor to zero and zero. 01:29.770 --> 01:32.130 OK, now let's change this. 01:32.250 --> 01:32.970 Let's change. 01:33.300 --> 01:35.690 Let's put three here. 01:36.690 --> 01:45.860 So we are going to start to set the Khutsong and the three, so the fourth column and the first line, 01:46.200 --> 01:48.900 let's see, we don't applaud the poor. 01:51.210 --> 01:58.920 And you can see there is nothing on the first three columns we start to print at the fourth column and 01:58.920 --> 02:04.350 the first line, not if I put, for example, zero and one. 02:04.390 --> 02:05.370 Let's see what happens. 02:07.980 --> 02:14.160 And now you can see the HelloWallet is printing from the first column that's on the Seagram line. 02:15.170 --> 02:20.150 And now let's say I want to bring Telo in the first line and world in the second line, what I can do 02:20.420 --> 02:31.750 is send the cursor to zero zero or just not set it at all and then set Kyozo at zero one and then ency 02:32.750 --> 02:35.510 print world. 02:36.770 --> 02:39.530 Like this is from here. 02:39.980 --> 02:46.280 OK, hello on the first line here and world on the second line, let's bring that. 02:49.060 --> 02:54.610 OK, we have hello on the first line and what on the segment, so as you can see, when you change the 02:54.610 --> 03:01.600 course, so it will change the course of the next print, OK, to keep the text that is already on the 03:01.600 --> 03:02.070 screen. 03:02.320 --> 03:07.480 So it's very convenient to put some text somewhere and some other text elsewhere. 03:07.480 --> 03:10.660 And you can organize your display screen as you want. 03:11.080 --> 03:13.140 Now let's see, let's say, for example, I use. 03:13.150 --> 03:16.570 So I'm going to use a delay here just to wait for one second, OK? 03:17.200 --> 03:19.060 And let's say a print. 03:20.450 --> 03:21.040 Odili. 03:22.170 --> 03:29.400 So I bring Telo on the first plane and then they put the closer to the signal a print world, I wait 03:29.400 --> 03:32.420 one second, I print Ardino that see what happens. 03:35.840 --> 03:40.230 As you can see, Alino is printed just after what? 03:40.250 --> 03:44.960 OK, so whenever you print something that will also move the cursor. 03:45.020 --> 03:50.590 OK, so the cursor here is at zero one and then so it would be a zero in here. 03:50.930 --> 03:58.500 And then one one two one three one four one five one six one. 03:58.760 --> 04:04.880 So when you are here, it's like you have said the cursor to six one, OK, and now let's say I'm doing 04:04.880 --> 04:11.170 this acidy dot six cursor with zero one again. 04:12.170 --> 04:15.990 So now I'm forcing Newcastle to go back to zero one. 04:16.010 --> 04:17.270 Let's upload. 04:18.370 --> 04:20.380 And let's see what we get here. 04:21.400 --> 04:27.700 You can see Hello, world and in hello and we know, OK, the world has been replaced. 04:27.940 --> 04:36.280 So whenever you print some text, what it will do is it will replace all the previous text that was 04:36.280 --> 04:37.960 printed at the same place. 04:38.070 --> 04:43.990 OK, so here I said, of course, zero one, I bring some text and then I said, OK, just go back to 04:43.990 --> 04:44.710 the same place. 04:44.710 --> 04:48.940 I bring some other text so the previous text will be replaced. 04:49.420 --> 04:52.000 So now you know a little bit better how it works. 04:52.000 --> 04:58.600 And I really encourage you to do some experiment, OK, to print text in different parts of the city, 04:58.900 --> 05:00.810 replace some text, etc.. 05:01.120 --> 05:01.630 And now what? 05:01.630 --> 05:03.520 We can do a nice application. 05:03.520 --> 05:11.170 Quick one is to so I'm going to keep Pelo on the first line and then to print a counter. 05:12.980 --> 05:21.570 OK, that's initialize a counter and counter these zero and in the look function, what I'm going to 05:21.570 --> 05:23.730 do is LCD said. 05:26.250 --> 05:30.430 So what I want to do here is print hello and then the counter. 05:31.290 --> 05:33.510 So I went you to set the console on. 05:33.510 --> 05:35.400 So this is column zero. 05:35.760 --> 05:38.190 One, two, three, four, five. 05:38.490 --> 05:41.700 And I want to add another space, so that would be six. 05:42.690 --> 05:46.580 I'm going to use six and then zero for the first column. 05:47.010 --> 05:52.170 So every time in the loop I said the cursor to six zero and then I do acedia print. 05:53.870 --> 06:00.140 Conter so I can bring a vegetable like this, it would bring the result of a viable and then let's do 06:00.140 --> 06:01.670 conter plus plus. 06:02.450 --> 06:09.530 OK, and let's OK for just because this is Conexion, let's add a delay of five hundred milliseconds. 06:10.280 --> 06:12.080 But with this we should be printing. 06:12.440 --> 06:13.060 Hello. 06:13.100 --> 06:16.340 One, two, three, four zero, one, two, three, etc.. 06:16.610 --> 06:18.560 Let's load. 06:20.110 --> 06:22.270 The program and to see what it does. 06:23.350 --> 06:28.870 Hello, zero, one, two, three, and you can see the counter is increasing and every time the new 06:29.170 --> 06:33.040 number is replacing the previous one, why is that? 06:33.040 --> 06:37.720 Because simply we just put the cursor to the same place every time. 06:38.060 --> 06:42.040 OK, that's pretty much it actually, with just you can already do a lot of things. 06:42.340 --> 06:45.660 And just one final note if you want to clear the screen. 06:46.120 --> 06:49.470 So if you want to clear that onto your screen, we have no character. 06:49.480 --> 06:53.710 You can see the clear like this and this would clear the screen. 06:53.720 --> 06:55.630 So at any time of your program.
