00:00:04,760 --> 00:00:09,190
‫Welcome to the RTC 7 BCT display demonstration.

2
00:00:09,380 --> 00:00:17,960
‫I currently have the BCT display running on the RTC 7 where I have a four digit seven segment display

3
00:00:18,140 --> 00:00:25,070
‫located on the breadboard where I have each of the seven segments are connected through a 56 ohm resistor

4
00:00:25,460 --> 00:00:26,930
‫into the J.

5
00:00:26,930 --> 00:00:35,660
‫P. mount port of the RTC 7 and I have each of the digit selects running through a 2 and 39 no for unpin

6
00:00:35,660 --> 00:00:44,660
‫transistor where I have a 470 ohm resistor connected to the base of these transistors and then fed back

7
00:00:44,750 --> 00:00:48,800
‫into the J.B. port payment of the RTC 7.

8
00:00:48,800 --> 00:00:58,130
‫Now if I have and I haven't reset currently So here's a port on reset my sarcy account show up on the

9
00:00:58,130 --> 00:01:02,940
‫7 segment display and this is counting in binary code decimal.

10
00:01:02,960 --> 00:01:08,400
‫So it's a way we can understand you know four five six seven eight nine.

11
00:01:08,960 --> 00:01:10,180
‫So and so forth.

12
00:01:10,280 --> 00:01:17,450
‫If I switch and now I'll be counting and hex you'll notice we go up through five six seven eight nine

13
00:01:17,450 --> 00:01:19,780
‫ABC F F G.

14
00:01:19,790 --> 00:01:25,080
‫Now if I go ahead and toggle this out it switches back over to decimal.

15
00:01:25,280 --> 00:01:31,520
‫So the decimal value and as soon as I toggle I go directly to hex and I can also switch and this will

16
00:01:31,520 --> 00:01:38,120
‫put me back to zero and if I plot 0 I'll start recounting from 1 on up.

17
00:01:38,120 --> 00:01:41,350
‫Now if I'm in hex You'll notice I go from 1 on up to F..

18
00:01:41,660 --> 00:01:43,430
‫And so on and so forth.

19
00:01:43,490 --> 00:01:48,110
‫And so as I go through I can just set this switch here and toggle back and forth while I want to go

20
00:01:48,110 --> 00:01:54,260
‫in hexadecimal or if I want to go an actual binary code of decimal as well.

21
00:01:54,260 --> 00:01:57,950
‫You'll notice that the count is counting at 4 digits per second.

22
00:01:57,950 --> 00:02:05,320
‫That's because the Peter Block We have specified to run at 4 Hertz meanings that will have it will count.

23
00:02:05,540 --> 00:02:07,660
‫Increase the count four times every second.

24
00:02:07,850 --> 00:02:10,480
‫So by changing that value we can have it go slower.

25
00:02:10,550 --> 00:02:12,980
‫So it's easier to see or you can have it run faster.

26
00:02:12,980 --> 00:02:16,640
‫I want it to go fast enough so you can see it change to the various digits.

27
00:02:16,640 --> 00:02:21,220
‫But I also want it to be slow enough so that you can see what's actually happening.

28
00:02:21,250 --> 00:02:25,990
‫And so this is what the BCT display should look like running on your RTC 7.
