00:00:04,010 --> 00:00:09,770
‫Welcome to the BCT display demonstration with the bases to board the bases to board.

2
00:00:09,770 --> 00:00:16,470
‫We have an on board four digit 7th segment display and therefore we do not need the external 7th segment

3
00:00:16,470 --> 00:00:19,290
‫display on the actual breadboard.

4
00:00:19,310 --> 00:00:25,150
‫The only other things we're using for the BCT display are the two slide switches switch zero and switch

5
00:00:25,170 --> 00:00:33,200
‫one switch zero determines whether we're counting in hexadecimal or binary coded decimal and which one

6
00:00:33,500 --> 00:00:35,880
‫enables or disables the counter.

7
00:00:35,910 --> 00:00:38,090
‫Right now we have switch 1 port high.

8
00:00:38,090 --> 00:00:39,800
‫So it's in a reset state.

9
00:00:39,850 --> 00:00:46,220
‫Therefore our counter is staying at a zero in order to start counting or go ahead and switch the switch

10
00:00:46,220 --> 00:00:47,450
‫one down.

11
00:00:47,960 --> 00:00:53,480
‫And as soon as I knew that you know we start to count and we're counting in binary code to decimal or

12
00:00:53,480 --> 00:00:59,600
‫decimal format the format that humans were most familiar with and one two three four five six seven

13
00:00:59,600 --> 00:01:02,900
‫eight nine ten so on and so forth.

14
00:01:02,900 --> 00:01:06,440
‫Now if I take that slide switch zero and pull that high.

15
00:01:06,590 --> 00:01:11,870
‫It'll take this count in the middle of the count convert it to the hexadecimal value and continue counting

16
00:01:11,870 --> 00:01:13,160
‫in hexadecimal.

17
00:01:13,160 --> 00:01:20,240
‫So when I pull that high to see we now are starting to count and the hexadecimal format where we're

18
00:01:20,240 --> 00:01:28,280
‫going through a B C D E F and so on on through and the rate at which we're counting is determined by

19
00:01:28,280 --> 00:01:33,680
‫the P.W. end and put we have regenerating the clock and we're counting off of that which we have currently

20
00:01:33,680 --> 00:01:34,810
‫set to four Hertz.

21
00:01:34,850 --> 00:01:35,300
‫That's.

22
00:01:35,330 --> 00:01:40,850
‫So as this is counting you can see the updates quick enough so you can kind of see as it cycles through.

23
00:01:40,910 --> 00:01:46,190
‫You can if you want to count faster or you just make that rate a higher rate or you want to call slower.

24
00:01:46,190 --> 00:01:51,360
‫You make that a slower rate you make it one her count every second you count up 1.

25
00:01:51,450 --> 00:01:53,710
‫And so I can go ahead and just switch back and forth.

26
00:01:53,720 --> 00:01:59,600
‫So right now the value haven't hexadecimal I can switch it down and there it goes to your decimal value.

27
00:01:59,720 --> 00:02:05,940
‫And if I pull my reset I can reset it when I get poort low again we start back at zero.

28
00:02:06,110 --> 00:02:08,570
‫Now I'm still in the binary code of decimal.

29
00:02:08,570 --> 00:02:13,150
‫I can switch to hexadecimal format and I'll do a reset.

30
00:02:13,630 --> 00:02:19,130
‫Pull it back low and now we're counting in hexadecimal what you notice once you reach the nine you go

31
00:02:19,130 --> 00:02:21,300
‫through the ABC.

32
00:02:21,460 --> 00:02:22,270
‫Yeah.

33
00:02:22,580 --> 00:02:28,100
‫So and so forth and that is the BCT display demonstration running on the bases two board.
