00:00:04,940 --> 00:00:15,110
‫Welcome to this algorithm in the Alieu lab setup if your board doesn't have 16 different 7 segment display

2
00:00:15,110 --> 00:00:20,830
‫digits this is a recommended way you can set up a lab to complete these.

3
00:00:21,170 --> 00:00:28,670
‫What I'm using is I have four different four digit seven segment displays where all of these segments

4
00:00:28,730 --> 00:00:35,970
‫of seven same display your A B C D E F and G are all tied together.

5
00:00:35,990 --> 00:00:43,340
‫So I have all these wires are tying the a portion of the 7 segment display for the first the first segment

6
00:00:43,340 --> 00:00:44,730
‫is tied to a.

7
00:00:44,870 --> 00:00:47,980
‫Every single one of these segments are tied together.

8
00:00:48,080 --> 00:00:56,210
‫So I only have 7 different resistors that I'm using to control the current for all of these digits.

9
00:00:56,210 --> 00:01:01,580
‫And the way I'm doing that is through the use of multi multiplexing and we're multiplexing by we have

10
00:01:01,670 --> 00:01:09,470
‫16 of these two in thirty nine or four and transistors that we're using to toggle we turn one on at

11
00:01:09,470 --> 00:01:14,330
‫a time and we just toggle through fast enough so it appears that all the segments are lit up at the

12
00:01:14,330 --> 00:01:15,350
‫same time.

13
00:01:15,710 --> 00:01:18,130
‫And the way these are connected.

14
00:01:18,260 --> 00:01:23,510
‫Each one of these packages has four different pins that are tied to the digits selects.

15
00:01:23,630 --> 00:01:30,050
‫So when you activate that pin whatever value you have on your segments will light up that individual

16
00:01:30,380 --> 00:01:31,130
‫segment.

17
00:01:31,250 --> 00:01:39,650
‫And so all of these transistors are connected through all the different different digits on a 7 segment

18
00:01:39,650 --> 00:01:40,280
‫display.

19
00:01:40,430 --> 00:01:46,160
‫And these have a 470 ohm resistor connected to the base of the transistor.

20
00:01:46,160 --> 00:01:51,470
‫The collector is connected to your power or your three point three bolts.

21
00:01:51,560 --> 00:01:59,100
‫The base is connected to the 470 ohm resistor which is controlled by the FPGA where you develop inboard

22
00:01:59,170 --> 00:02:06,650
‫that Togolese by sending a logic one or a high signal you activate that specific segment on the 7 segment

23
00:02:06,650 --> 00:02:15,080
‫display and then the emitter of the transistor is connected to the digit select on each of the seven

24
00:02:15,080 --> 00:02:16,400
‫segment displays.

25
00:02:16,500 --> 00:02:22,960
‫And so that is the lab set up that I'm using for both boose algorithm and the Alieu algorithm.

26
00:02:22,970 --> 00:02:26,310
‫So this is just a recommended way you can set up your lab.

27
00:02:26,320 --> 00:02:32,990
‫If your board has various It has seven Sigma displayed on already such as the basis to where the base

28
00:02:32,990 --> 00:02:33,880
‫is 3.

29
00:02:34,010 --> 00:02:41,390
‫I only use the bottom to set here the Bound 2 7 segment displays because I'm using one on the basis

30
00:02:41,400 --> 00:02:44,630
‫two and basically board to display various things.

31
00:02:44,630 --> 00:02:48,380
‫And I just use this here to display my actual output.

32
00:02:48,740 --> 00:02:53,440
‫And that is the lab setup for that Alieu and boose algorithm.
