00:00:04,090 --> 00:00:09,680
‫Welcome to the lab set up for the BCT display and linear feedback shift register.

2
00:00:09,790 --> 00:00:17,440
‫This set up will be used for both labs if you have a PGA board such as the bases two or bases three

3
00:00:17,710 --> 00:00:21,190
‫that already contains a four digit seven segment display.

4
00:00:21,190 --> 00:00:25,320
‫You will not have to set up a display on a breadboard.

5
00:00:25,320 --> 00:00:27,690
‫You can use that display located on your board.

6
00:00:27,700 --> 00:00:33,910
‫However if you're using already or the order of the 7 as I am in this course you will need to have an

7
00:00:33,910 --> 00:00:38,560
‫external 7:07 display set up a show for the setup.

8
00:00:38,560 --> 00:00:47,200
‫We have the four digit seven segment display where we then have 8 outputs that were tying back to our

9
00:00:47,560 --> 00:00:53,060
‫FPGA and we're tying these back through a 56 ohm resistor.

10
00:00:53,080 --> 00:00:55,980
‫We also have sensors for different digits.

11
00:00:56,170 --> 00:01:01,800
‫We have four digit select signals that we are controlling with the FPGA.

12
00:01:01,810 --> 00:01:11,800
‫However we're using a 2 and 39-A for transistor with a 470 ohm resistor connected to the base used to

13
00:01:11,800 --> 00:01:15,250
‫control each of the different digits.

14
00:01:15,250 --> 00:01:23,200
‫And we have an external I'm using an Arduino board but an external source to power the 3.3 volts used

15
00:01:23,410 --> 00:01:25,420
‫to power the 7 segment display.

16
00:01:25,780 --> 00:01:31,630
‫And so with these different with the different digit select signals you're going to take and tie those

17
00:01:31,630 --> 00:01:38,730
‫back into your FPGA board using either a Piedmont port or any type of pin you can connect to.

18
00:01:38,830 --> 00:01:43,990
‫And that's what we use to select the different digits on a seven Sigma display we're using to light

19
00:01:43,990 --> 00:01:44,480
‫up.

20
00:01:44,550 --> 00:01:48,460
‫Then we also have the out seven signals we're reading back.

21
00:01:48,550 --> 00:01:55,000
‫We're going to select which of the individual segments on the 7 segment display are lit up and so that

22
00:01:55,000 --> 00:02:00,700
‫is the lab set up for the binary code decimal display in a linear feedback shift register.
