00:00:01,170 --> 00:00:06,900
What is the basic structure of a seven segment display, this lecture gives you an overview of a seven

2
00:00:06,900 --> 00:00:09,110
segment structure and how it works.

3
00:00:11,030 --> 00:00:16,790
A seven segment display consists of eight ladies, seven of them are used to show a pattern of a decimal

4
00:00:16,790 --> 00:00:17,240
number.

5
00:00:17,660 --> 00:00:20,360
These ladies are named from a Tukey.

6
00:00:21,660 --> 00:00:25,230
The last lady shows a decimal point denoted by deep.

7
00:00:27,160 --> 00:00:32,360
There are two different types of configuration for a seven segment display, including common A. and

8
00:00:32,380 --> 00:00:34,060
common catalogue configurations.

9
00:00:34,980 --> 00:00:41,300
In the configuration of the common A. all anodes of ladies are connected to the high voltage level or

10
00:00:41,310 --> 00:00:47,040
lodging value one, therefore, to turn on a segment, the logic value zero should drive the corresponding

11
00:00:47,040 --> 00:00:51,360
cathode of the corresponding ality in the configuration of the common cathode.

12
00:00:51,360 --> 00:00:56,280
All the early decathletes are connected to low voltage level or logevall value zero.

13
00:00:56,940 --> 00:01:03,090
Therefore, to turn on a segment the logic value one should derive the corresponding anode of the corresponding.

14
00:01:06,010 --> 00:01:11,860
As an example, let's consider coming its own segment, if you want to show the number three, then

15
00:01:11,860 --> 00:01:18,520
the Bindura value of one zero one one zero zero zero zero should be applied to the lady's cathodes.

16
00:01:21,370 --> 00:01:26,290
The switch control biologic value usually controls the common connection in a seven segment.

17
00:01:26,860 --> 00:01:32,380
This technique helps us to have more control on a certain segment and turn off that regardless of the

18
00:01:32,380 --> 00:01:38,640
code on the data lines in this figure, a transistor which controls a common and sound segment.

19
00:01:38,860 --> 00:01:44,620
Therefore, to turn on the cell and segment, the switch should be driven by the logic value zero and

20
00:01:44,620 --> 00:01:47,140
proper data should be applied to the cattle's.

21
00:01:49,390 --> 00:01:53,470
What are the codes for different decimal digits in the next lecture?

22
00:01:53,650 --> 00:01:54,960
I will answer this question.

23
00:01:57,050 --> 00:02:02,930
These are the takeaway messages to control seven segment displays, a controller should provide two

24
00:02:02,930 --> 00:02:09,380
groups of signals control signals and data signals, whereas the control signals enable seven segments

25
00:02:09,500 --> 00:02:10,670
or turn them on.

26
00:02:10,940 --> 00:02:15,920
The data signals provide the proper code for the number to be displayed on the Sun segments.

27
00:02:17,930 --> 00:02:19,250
Now, the police for this lecture.

28
00:02:20,260 --> 00:02:26,170
Find the logic value of the control and data signals to show the number four on this common A. seven

29
00:02:26,170 --> 00:02:26,710
segment.
