‫Welcome to the barrel shifter lab set up are going to show you how to set up the 7:7 display and switches

2
00:00:12,500 --> 00:00:15,290
‫to be used with the barrel shifter Lab..

3
00:00:15,590 --> 00:00:23,420
‫I have four digit seven segment display which is the same 772 display we've used for the binary code

4
00:00:23,420 --> 00:00:29,250
‫decimal display linear feedback's shift register and the potentiometer interface.

5
00:00:29,420 --> 00:00:37,640
‫We have seven of the 56 ohm resistors that we are pouring from each of the different segments on the

6
00:00:37,640 --> 00:00:44,690
‫7st and sleigh which we then feed back to the FPGA we are interfacing with.

7
00:00:44,690 --> 00:00:50,970
‫And we also have four different digit selects which will be used to select each one of the digits on

8
00:00:50,970 --> 00:00:53,760
‫the four digit seven segment display.

9
00:00:54,050 --> 00:01:04,650
‫And we have 2 and 3 9 4 transistors with a 470 ohm resistor connected to the base of the transistor

10
00:01:05,040 --> 00:01:12,090
‫which we then feed back into the FPGA which is used to toggle through and multiplexed the different

11
00:01:12,450 --> 00:01:14,980
‫7 segment each segment.

12
00:01:15,000 --> 00:01:22,800
‫We also have two switches that we need to use now depending upon the type of board you're using if you're

13
00:01:22,800 --> 00:01:29,280
‫using the arty or the Arty's you 7 you will need to connect a few extra switches onto the breadboard

14
00:01:29,610 --> 00:01:30,570
‫with the Arti.

15
00:01:30,670 --> 00:01:34,740
‫You'll need two extra switches with the RTC 7.

16
00:01:34,830 --> 00:01:36,370
‫You will need three.

17
00:01:36,390 --> 00:01:41,820
‫However if you use a board such as the basis three there's enough switches onboard that you don't have

18
00:01:41,820 --> 00:01:47,250
‫to have any switches connected on your breadboard as well as the seven segment display.

19
00:01:47,430 --> 00:01:53,730
‫So depending on the FPGA board you're using but if you're using one that doesn't have an onboard 7 display

20
00:01:54,240 --> 00:01:59,670
‫or enough on board switches you don't need to connect them up like so in the switches.

21
00:01:59,670 --> 00:02:02,890
‫I have one side is tied to ground.

22
00:02:03,120 --> 00:02:10,540
‫The other side is tied to your high voltage or 3.3 volts and then the output which is the center pin

23
00:02:11,080 --> 00:02:13,180
‫is fed back into.

24
00:02:13,330 --> 00:02:17,480
‫PJ Development Board and that is the barrel shifter set up.
