WEBVTT 00:02.040 --> 00:07.410 Welcome to life for the last seven segment display in this video I'm going to show you what the complete 00:07.410 --> 00:10.290 solution should look like when your base is to board. 00:10.470 --> 00:12.770 Now if you get stuck or have any issues. 00:13.230 --> 00:15.630 Be sure to look in the back of the references section. 00:15.630 --> 00:16.200 I have several. 00:16.200 --> 00:23.130 Yes I said that go through some component instantiations which are what the main part of the Slavs focused 00:23.130 --> 00:23.520 on. 00:23.730 --> 00:29.040 Or if you get stuck with that and can't figure out how to get this run Feel free to send me an email. 00:29.070 --> 00:30.930 I'm more than willing to help if you're ready. 00:30.930 --> 00:32.830 Grab your board must go. 00:33.200 --> 00:33.570 OK. 00:33.600 --> 00:41.110 So here we have lamb for which is hexa sent in segment display running on a basis to board. 00:41.270 --> 00:47.890 And with this lab we are going to be exercising the certain segment displays right here and there. 00:47.910 --> 00:55.680 We're just using the the two two segments to your far left and with easy to follow gave you you've got 00:55.740 --> 00:56.180 down. 00:56.190 --> 01:02.640 We're going to be using all these switches and we've got that far in left for here. 01:02.710 --> 01:08.550 Is like your input one in the far right here is your input to which it doesn't really matter which ones 01:08.550 --> 01:14.130 which are just just as long as you have four switches and you know what four switches are tied to one 01:14.130 --> 01:14.790 of the segment. 01:14.820 --> 01:22.900 One of these ways and the way this works here is as you talk about these switches it's going to change 01:22.900 --> 01:26.000 your value on your and segment display right here. 01:26.280 --> 01:31.880 And like with all the previous lives with the clocking we were doing with the pushbuttons here however 01:31.890 --> 01:34.070 we're not doing any of that here. 01:34.230 --> 01:39.900 That's all controlled from the board here because if we were or because what is working is this is actually 01:39.900 --> 01:46.500 the multiplex where each of these displays is actually being displayed individually but it's happening 01:46.500 --> 01:48.660 so fast that you can't even tell. 01:48.660 --> 01:54.080 It looks like they're just playing the same exact time which if you look at the user guy in the references 01:54.080 --> 01:59.880 section of the bases or they talk about that in pretty good detail that they have like two or three 02:00.030 --> 02:02.820 pages that talk about how how this segment is playing. 02:02.830 --> 02:05.830 It's multiplexed and how to do that. 02:06.180 --> 02:14.620 So what we'll do here is change the values of these switches which is essentially a four for that you 02:14.970 --> 02:20.560 that is going to be represented on here which if you have a format value which in hex counts from 0 02:20.560 --> 02:21.320 to f. 02:21.450 --> 02:25.460 So for example here I've got one change that value 1 there. 02:25.740 --> 02:33.440 Now for binary to that switch there is me to their binary 3 3. 02:33.450 --> 02:45.720 Now for a for toggle this term those down I get to 4 5 6 7 8 and 9 02:48.500 --> 02:52.900 and 10 which is you know X hexadecimal. 02:53.120 --> 02:53.660 No 10. 02:53.670 --> 02:58.800 It goes from 9 and goes to B C D E. 02:59.160 --> 03:06.280 So the may have Arseny the math. 03:06.490 --> 03:11.050 So you can see basically that and this one is the same exact. 03:11.070 --> 03:13.770 It's just replayed on the on the other display there. 03:13.790 --> 03:15.450 So I get that one. 03:15.470 --> 03:21.970 I got a one at four five but always down I got 0 0 1 1. 03:22.040 --> 03:28.220 So this is a very useful way to display information if you've got a whole byte of data somewhere located 03:28.220 --> 03:28.970 in your FPGA. 03:28.970 --> 03:30.320 You want to know what that is. 03:30.320 --> 03:37.460 You can use this surrogate of the slab to go ahead and display it on these sectors that have 7 display 03:37.850 --> 03:38.610 and where you are. 03:38.630 --> 03:41.270 You don't have to use AOL to represent this data. 03:41.270 --> 03:48.150 So like if I have no idea that's got this combination you know you can look at any reason you can understand 03:48.150 --> 03:49.880 what that is. 03:50.150 --> 03:55.910 You can just tell you with just you know seven the end you know 72 of them and you can get this binary 03:56.210 --> 03:57.880 representation of that. 03:57.920 --> 04:03.240 And so this is the last four here of the Nexus 7 display. 04:03.260 --> 04:07.460 And like I said if you have any problems or this doesn't make sense to you or you don't really know 04:07.460 --> 04:08.540 what's going on. 04:08.540 --> 04:09.550 Feel free to email me. 04:09.590 --> 04:11.090 I'm more than happy to help. 04:11.090 --> 04:12.740 I want you guys to learn this. 04:12.740 --> 04:13.480 I really do. 04:13.510 --> 04:16.710 I want you to be able to do this and have that aha moment. 04:16.730 --> 04:18.800 I know and understand what's going on.
