WEBVTT 00:00.210 --> 00:08.160 This is the number 10 of the final project, and in this step, what we are going to do is to be able 00:08.160 --> 00:11.890 to toggle between different screens on the LCD screen. 00:11.910 --> 00:18.170 OK, so the default one we have is to print the distance and then to bring someone in, for example, 00:18.390 --> 00:20.660 when the application is not locked, of course. 00:21.000 --> 00:23.400 And what we want to do is maybe to bring something out. 00:23.440 --> 00:29.040 So what we are going to print is the instructions to resist to the default settings. 00:29.190 --> 00:35.430 And when we are in that screen, we are going to be able also to reset the default setting using the 00:35.530 --> 00:36.480 remote controller. 00:36.720 --> 00:44.010 So in this that we are going to create some mode for the LCD so we can toggle between different mood 00:44.010 --> 00:47.260 and different displays using the remote control. 00:47.400 --> 00:53.730 And then for the second mode, the reset setting mood, we're going to add the action to reset the settings. 00:54.330 --> 00:57.390 So let's start and let's add some. 00:58.050 --> 00:59.300 So let's do that here. 01:01.070 --> 01:03.050 So kidlets argument. 01:05.000 --> 01:08.310 Distance unit, and here it's a recruitment. 01:09.350 --> 01:15.040 LCD mode, so let's define acidy mode. 01:16.930 --> 01:22.770 Distance, which is the default one, that's zero defined and said. 01:24.270 --> 01:26.400 Moad Sitting's. 01:27.360 --> 01:35.970 One and actually in the next step, we are also going to add another mode, so we have to and let's 01:35.970 --> 01:45.060 create here in LCD mode is equal to the estimated the distance. 01:45.070 --> 01:48.830 So quite similar to what we have done with the distance. 01:49.170 --> 01:51.410 OK, that's the same thing. 01:51.810 --> 01:53.150 Now I'm going to. 01:53.230 --> 01:57.690 So let's find the angle I command. 01:57.940 --> 02:01.830 I'm going to add a new function void toggle. 02:03.040 --> 02:05.110 LCD screen. 02:06.830 --> 02:12.320 And I'm going to use a switch here, because for now we have two modes, and the next step I'm going 02:12.320 --> 02:15.630 to add another mode or switch will be quite appropriate. 02:15.680 --> 02:19.180 You switch with the exiting mode. 02:21.060 --> 02:31.140 And then we're going to take the case LCD mode, this tends to do and then break and in the case LCD 02:31.470 --> 02:32.100 mode. 02:33.440 --> 02:39.290 Settings to do and break and the default. 02:40.970 --> 02:42.010 So what do we want to do? 02:42.020 --> 02:45.650 We want to simply modify the LCD mode. 02:45.660 --> 02:50.300 So if the LCD mode is distance, we do LCD mode. 02:52.200 --> 03:00.210 Become settings, if not, the mode is settings, we do LCD mode becomes. 03:01.890 --> 03:02.580 Defense. 03:03.970 --> 03:10.150 And the default one, basically, if it's none of the two, which should not happen, but if it happens, 03:10.150 --> 03:15.270 which we do, we simply LCG mode is equal to sitting to distance. 03:15.280 --> 03:17.710 We set it back to the default one. 03:18.290 --> 03:23.020 So here we have the default. 03:24.350 --> 03:25.520 OK, that's the same. 03:27.410 --> 03:34.100 So he, as you can see, another simple state metion with a switch and I have used the switch, so when 03:34.100 --> 03:38.880 we add another mode in the next step, that will be super easy to modify. 03:40.030 --> 03:42.100 And I'm going to call this. 03:43.540 --> 03:46.330 So we can toggle between different screens. 03:46.360 --> 03:52.930 We're using the button up and button down to go to the left side, to the next screen, up to the previous 03:52.930 --> 03:55.090 one here, because we only have two screens. 03:55.420 --> 04:02.530 Well, we don't need to worry about that for now because the previews and the next screen is the same 04:02.530 --> 04:03.430 if you have two screens. 04:03.430 --> 04:09.630 So I'm just going to toggle the screen whether we use up or down, OK, but we call the function with 04:09.640 --> 04:10.440 the same behavior. 04:10.750 --> 04:15.800 So now that we have toggled between the stage where we need to actually use that state to do something. 04:16.180 --> 04:20.510 So if we go back to our function, print distance on LCD. 04:20.800 --> 04:24.440 So first we check if it is locked, then we do this. 04:24.460 --> 04:26.450 So that is always going to be the case. 04:26.470 --> 04:31.270 OK, the locked behavior will always overwrite any other behavior. 04:31.690 --> 04:35.800 And then else I'm going to add as if LCD mode. 04:37.400 --> 04:38.480 Is equal to. 04:40.010 --> 04:44.030 And see mode dist.. 04:45.780 --> 04:53.640 With two equals, of course, so I'm only printing this if we are in the distance mode, OK? 04:54.480 --> 05:02.580 And if not, so if the application is not locked and not in the distance mode here on the print distance, 05:02.580 --> 05:03.720 we just print nothing. 05:04.200 --> 05:04.590 OK. 05:05.980 --> 05:15.460 And now what I'm going to do here is, well, when we switch to the mode settings here, I'm going simply 05:15.460 --> 05:22.090 to add here, if that's the mode is equal to the mode settings. 05:25.170 --> 05:33.810 Then I'm going to print the instructions to reset the settings, so let's say LCG got set, just saw 05:33.810 --> 05:43.980 with zero zero and then and see that print, that's a price of two and few spaces. 05:44.910 --> 05:55.890 And she said Couso zero one Ellsinore print reset settings. 05:58.270 --> 06:01.460 So I just printed the restriction on two lines. 06:01.480 --> 06:10.390 OK, so basically you see enough when we toggle the LCD screen, if we arrive at the mood settings. 06:11.490 --> 06:16.800 I'm going just to print that and that's it, and now because it's in the mode settings, we are not 06:16.800 --> 06:20.680 going to print anything else in the print distance on Esseily. 06:21.510 --> 06:23.340 And why are you writing this here? 06:23.340 --> 06:26.360 Because, well, simply we just need to write this once. 06:26.370 --> 06:27.990 I could have had it here. 06:27.990 --> 06:35.610 And as if LCG mode settings that would be called also whenever we want to print the distance on Elsley, 06:35.610 --> 06:42.150 but that's another functionality and that will print this many times per segan. 06:42.150 --> 06:43.290 And we don't need to do that. 06:43.290 --> 06:46.980 We just need to print it once when we said the modem. 06:47.010 --> 06:48.920 That's one thing I'm going to do here. 06:48.930 --> 06:55.680 It's also the entity that clear, OK, after I change the mode and is going to clear whatever is on 06:55.680 --> 07:01.660 the LCD screen, though, not if the mode is distance, we bring the distance with the other function. 07:02.040 --> 07:06.950 Now, if we go to settings, we clear, we print press on us to reset the settings. 07:07.000 --> 07:12.530 OK, then we are going to see how to do this section and then we toggle again. 07:12.540 --> 07:16.800 We are going back to the distance mode and in that case we clear the screen. 07:16.830 --> 07:22.630 We don't enter this and then we can continue to print the distance as we did before. 07:23.160 --> 07:29.850 And of course, if we ever lock the application, this will overwrite anything else that you try to 07:29.850 --> 07:30.300 print. 07:31.670 --> 07:39.890 And now that so let's say that we are in this screen, we are in the settings screen, which is seen 07:39.890 --> 07:44.020 press on off to reset settings, so the above is the button here. 07:44.390 --> 07:49.790 So I'm going to create a new function here, void reset settings. 07:51.700 --> 07:52.480 Let's say to. 07:57.170 --> 08:04.930 So here we have only one city that we can modify is the distance unique and the default is sentiment. 08:05.630 --> 08:10.460 But as an improvement for this final project, you could think of adding in many different settings, 08:10.460 --> 08:13.310 for example, doubling bright for the year. 08:13.550 --> 08:19.090 And it is the threshold to detect that an obstacle is on the way. 08:19.400 --> 08:25.100 So you could add many different settings, OK, that you can change, for example, with the remote 08:25.100 --> 08:26.930 controller and save to EPROM. 08:27.110 --> 08:32.510 And then when you call reset settings to default, you just reset all the settings to, well, to default. 08:32.780 --> 08:34.550 So here I'm going to check first if. 08:35.740 --> 08:42.790 So when we call that function from the handle, I recommend mean, to check if the ELSLEY mode is equal 08:42.790 --> 08:44.560 to LCB mode. 08:46.150 --> 08:55.170 Sitting's why I do that, because we are only going to be able to reset the settings when we are on 08:55.180 --> 08:56.410 the settings screen. 08:56.580 --> 09:00.100 OK, so if you want to reset the settings, you have to step first. 09:00.100 --> 09:05.740 You go to the screen and then you press off, OK, to, for example, to avoid that, you just reset 09:05.740 --> 09:07.500 the settings at any time. 09:07.750 --> 09:14.190 So to reset, I'm going to do distance units, set it back to distance. 09:14.950 --> 09:18.820 You need centimetres because I change the distance unit. 09:18.820 --> 09:21.050 I need also to do it from that. 09:21.730 --> 09:22.480 Right. 09:22.900 --> 09:29.260 We've become let's find this is the ultra distance unit. 09:30.640 --> 09:32.360 And these tensions. 09:34.780 --> 09:40.450 So if you have any other parameters of any other settings, you or is it then here and then what I'm 09:40.450 --> 09:44.470 going to do, I'm going to print a confirmation message on the AC. 09:44.560 --> 09:50.500 So let's do LTT clear and then SCD that sits. 09:52.420 --> 10:00.610 Tiso zero zero And she that print with let's say sitting's have. 10:02.020 --> 10:07.300 And in a city that sits just zero one. 10:08.940 --> 10:09.960 Nancy DePrince. 10:11.080 --> 10:13.540 Settings have been or is it? 10:14.690 --> 10:21.560 I don't add extra species here because I just cleared the screen before, so no need to add them and 10:21.560 --> 10:25.880 actually here because they clearly screen these, I could add them on. 10:25.880 --> 10:27.790 That's not the problem here. 10:28.940 --> 10:35.360 And I'm going to call that function from the IT when we press on the button. 10:37.380 --> 10:40.710 All right, it seems to me that the good is good. 10:40.740 --> 10:45.100 Now I'm going to verify and see it as a final project. 10:45.120 --> 10:46.500 Step number 10. 10:49.660 --> 10:59.320 And a quick recap here, so when we press the button up button down on the remote controller, we call 10:59.330 --> 11:02.420 the toggle and discreet, which is here. 11:02.770 --> 11:07.570 So now we have set an LCD mode, which is distance all settings. 11:08.560 --> 11:11.380 So when we talk on the screen, we are going to change the mode. 11:12.010 --> 11:16.600 And then depending on the movie, we are going to print different things on the LCD. 11:16.600 --> 11:20.920 So if the mode is distance, we print the distance as before. 11:21.250 --> 11:27.350 If the mode is settings, we print the message and instructions so we can present the settings, OK. 11:27.810 --> 11:31.270 And of course, if the application is locked, this will of the right. 11:31.270 --> 11:32.620 Any other behavioral. 11:33.640 --> 11:41.380 Now, when we are on the LCD mode settings, if we price on the off button, we call the reset settings 11:41.380 --> 11:47.070 to default, and so we see that we are actually in the correct mode to do that. 11:47.590 --> 11:53.280 And in that case, we just reset the settings and we print a confirmation message. 11:53.770 --> 12:00.430 And also one thing and going to the one small additional thing I'm going to do is when I unlock the 12:00.430 --> 12:07.290 application, I'm also going to the LCD that clear because now we have different modes. 12:07.300 --> 12:11.680 So if we have the distance mode, it's going to continue to print the distance. 12:11.680 --> 12:19.210 But if we are in the settings mode, because we just print the setting text once, we need to clear 12:19.600 --> 12:25.720 to make sure that we don't get the error message if we were in the settings mode. 12:26.110 --> 12:28.060 So now let's upload code. 12:30.900 --> 12:37.560 So the application is running as expected, normally with the default behavior, which is to print the 12:38.070 --> 12:40.890 distance and you can see here we print in inches. 12:40.920 --> 12:46.310 OK, that was the previous settings, the regular distance unit that I have set. 12:46.590 --> 12:52.170 And when I started to program, it was retrieved from the from memory. 12:52.560 --> 12:59.580 So what I'm going to do, I'm going to press on the button here the button Ildong to go to the different 13:00.660 --> 13:01.930 modes of the LCD. 13:01.950 --> 13:08.700 So this is the other mode where you can see press on off to reset settings so I can toggle between the 13:08.700 --> 13:11.970 distance and this sitting mode. 13:12.300 --> 13:18.730 Now, in this mode, I can just press on the off button and you can see settings have been there. 13:18.750 --> 13:20.310 Is it if I go back. 13:20.320 --> 13:28.010 So using the Ildong or you can see now I have the distance in centimeters, not in inches. 13:28.320 --> 13:31.050 So you can see that all the default settings. 13:31.050 --> 13:34.200 So we just have the distance you need. 13:34.380 --> 13:36.900 All the default settings have been reset. 13:37.380 --> 13:38.160 And of course. 13:38.610 --> 13:44.700 Well the thing is that if you have an obstacle, it still overrides everything and you can't well, 13:44.700 --> 13:46.020 you can't change the screen, OK? 13:46.200 --> 13:53.670 The only way is to press on the play button to unlock and then you can continue to do whatever you want 13:53.670 --> 13:54.270 with the screen. 13:55.190 --> 13:59.660 All right, and that will be the end of this step, and as you can see, that can be quite convenient 13:59.660 --> 14:06.200 to switch between different screens for the LCD to bring a different kind of informations, all different 14:06.200 --> 14:07.340 kind of actions.
