00:00:00,750 --> 00:00:07,140
How does a multi digit cell segment display work in the bases to report this lecture, will we with

2
00:00:07,140 --> 00:00:07,650
this question?

3
00:00:09,970 --> 00:00:17,080
A seven segment display consists of seven ladies that can be illuminated to show a specific decimal

4
00:00:17,080 --> 00:00:24,520
number as the ladies in the seven segment display available on the basis three board are in the common

5
00:00:24,520 --> 00:00:31,170
a. configuration to turn on a segment, we should drive that segment with the logic value zero.

6
00:00:31,240 --> 00:00:39,010
Therefore, to show number three, we should drive a segment with one zero one one zero zero zero zero

7
00:00:39,130 --> 00:00:40,030
binary code.

8
00:00:44,160 --> 00:00:50,100
There are 47 segment displays available on the basis three more, they have two groups of signals,

9
00:00:50,310 --> 00:00:52,470
data signals and control signals.

10
00:00:52,950 --> 00:00:55,520
Its seven segment has its own control line.

11
00:00:56,560 --> 00:01:00,040
If a control line is zero, the corresponding southern segment is on.

12
00:01:00,220 --> 00:01:01,680
Otherwise, it is of.

13
00:01:02,670 --> 00:01:09,030
There are eight data lines corresponding to seven segments plus decimal point on each display, these

14
00:01:09,030 --> 00:01:11,070
data are shared among Display's.

15
00:01:12,880 --> 00:01:16,780
Therefore, only one display should receive the data at a time.

16
00:01:20,090 --> 00:01:26,510
These are the seven segment codes for BCT digits from 029 that we use along this course.

17
00:01:29,100 --> 00:01:36,270
As we know, some the segment displays share the data lines, how can we drive for displays to show

18
00:01:36,270 --> 00:01:37,350
a multi digit number?

19
00:01:38,300 --> 00:01:40,670
The next lecture will cope with this question.

20
00:01:43,770 --> 00:01:51,660
These are our takeaway messages, multiple segment displays usually have the same data lines, but they

21
00:01:51,660 --> 00:01:53,340
have their own control lines.

22
00:01:55,040 --> 00:02:01,160
Certain segments in this report are configured as common items, therefore, to turn on a segment,

23
00:02:01,400 --> 00:02:03,660
the corresponding data line should be zero.

24
00:02:04,990 --> 00:02:10,810
To activate seven segment display on bases to report the corresponding control signal should be zero.

25
00:02:13,380 --> 00:02:18,870
Now, the quiz question, how many patrons can be shown on a seven segment display?
