00:00:02,460 --> 00:00:08,670
How can we show a multi digit number unforthcoming segment displays available on the basis of this lecture

2
00:00:08,880 --> 00:00:11,580
will give the basic idea of addressing this question.

3
00:00:14,980 --> 00:00:22,480
Died showing multiple digit numbers on for seven segment displays with shared data lines is Ty multiplexing

4
00:00:22,490 --> 00:00:27,620
the lines between seven segments such that each segment is active for a period of time?

5
00:00:28,360 --> 00:00:33,640
Therefore, we should turn on the displays one after another and then refresh that regularly.

6
00:00:35,350 --> 00:00:41,680
Each digit is illuminated just a quarter of the time, however, because the eye cannot perceive digits

7
00:00:41,680 --> 00:00:46,990
darkening before it is illuminated again, the digit appears continuously illuminated.

8
00:00:49,740 --> 00:00:55,770
Based on this discussion, there is an assigned time slot for each display during the time slot of a

9
00:00:55,770 --> 00:00:58,890
display, it's enabled signal should be active.

10
00:00:59,960 --> 00:01:05,720
The data lines are also should carry the southern segment code for a specific display during its time

11
00:01:05,840 --> 00:01:06,260
slot.

12
00:01:08,040 --> 00:01:13,440
This diagram shows the enable or control signal A for seven segments.

13
00:01:15,640 --> 00:01:22,870
The refresh period can be between one millisecond to 16 millisecond for basis board seven segment displays.

14
00:01:25,610 --> 00:01:31,700
Our salmon segment display controller consists of two italicize, the first Sipi implements a state

15
00:01:31,700 --> 00:01:36,980
machine to enable certain segments regularly and provides data for the enabled one.

16
00:01:37,820 --> 00:01:44,510
It receives a reference signal and for salmon segment codes for four digits and generates data and enabled

17
00:01:44,510 --> 00:01:46,710
signals for certain segment displays.

18
00:01:47,150 --> 00:01:50,900
The second type generates refresh signal, which is regular pulses.

19
00:01:54,750 --> 00:01:59,970
This timing diagram represents the output of the southern segment reference signal generated.

20
00:02:00,850 --> 00:02:05,420
As we have for Display's, its period is a quarter of the display refresh periods.

21
00:02:09,510 --> 00:02:15,030
How can we design these two ipis in the next lecture will cope with this question.

22
00:02:17,240 --> 00:02:23,590
These are our takeaway messages, multiple seven segments usually share the same data lines, a time

23
00:02:23,600 --> 00:02:27,940
multiplex mechanism should be used to drive some segment displays with their data.

24
00:02:30,800 --> 00:02:31,730
Now, the police question.

25
00:02:33,350 --> 00:02:39,500
If you assume the average period are for seven segments is 16 millisecond, what is the period of the

26
00:02:39,500 --> 00:02:40,620
seven segment reference?
