1
00:00:02,730 --> 00:00:09,310
Talent will come to this and you listen and watch I will show you how you can easily read in books that

2
00:00:09,310 --> 00:00:11,970
are using pick it up.

3
00:00:13,420 --> 00:00:20,880
Now as you can see this is the first example that we discussed earlier in order to turn the flash off.

4
00:00:21,110 --> 00:00:30,470
When I said even let's say that we added a push button on port see.

5
00:00:30,550 --> 00:00:36,400
First we need to define party output.

6
00:00:36,960 --> 00:00:38,890
C equals zero.

7
00:00:38,920 --> 00:00:50,640
X x f with a dimension that using F F and hexadecimal because Scoby this the tears as you can see it

8
00:00:50,640 --> 00:01:02,970
means that all because of Part B of wafty are not about the same thing must be done which is had the

9
00:01:02,970 --> 00:01:09,750
initial value of zero for all of this pain or this port pins pt. s..

10
00:01:09,750 --> 00:01:11,080
Burns.

11
00:01:11,190 --> 00:01:21,290
Now if you want to read let's say that we have a brush but all connected to board t of zero.

12
00:01:22,750 --> 00:01:35,810
Clearly the set of brackets here and in the tears here we need to ask if Paul's seed of zero equals

13
00:01:35,820 --> 00:01:37,290
one.

14
00:01:37,290 --> 00:01:48,020
Now if that is the value all party equals one this means that the switch is blessed and if the switch

15
00:01:48,020 --> 00:01:59,420
is placed do execute this code which will flash for the ones to turn but the wait for a second to turn

16
00:01:59,420 --> 00:02:01,920
it off and wait for half a second.

17
00:02:02,510 --> 00:02:03,600
Now let's combine it

18
00:02:09,740 --> 00:02:11,810
as you can see everything is done.

19
00:02:11,810 --> 00:02:15,230
Now let me explain what happened here.

20
00:02:17,650 --> 00:02:26,580
As you can see in this area we have it was just used for reading in both values.

21
00:02:27,980 --> 00:02:35,050
And we have lotteries start to sending out what values now form to do the very same code.

22
00:02:35,050 --> 00:02:44,410
This code in let's say pick 16 of we want to use language just we would like the very same lines.

23
00:02:44,410 --> 00:02:50,280
Let me just go with this code to show you the difference.

24
00:02:50,330 --> 00:02:59,630
And we will write port D for the.

25
00:02:59,800 --> 00:03:07,140
So this code will be for pick 16 and this code will be for pick it up.

26
00:03:07,210 --> 00:03:14,860
The main difference here is that port here is used for input for reading input and sending output while

27
00:03:14,860 --> 00:03:21,940
here port is only used for reading about why if you want to send output we need to use.

28
00:03:22,210 --> 00:03:28,720
I know that this means extra programming in Forth but it will solve the problem that we already mentioned

29
00:03:28,870 --> 00:03:31,280
in a separate section.

30
00:03:31,330 --> 00:03:33,960
Read modify write problem.

31
00:03:34,030 --> 00:03:44,050
You should check it out to know what's this problem and using Pythian gives you a lot of modules from

32
00:03:45,400 --> 00:03:49,230
other Rubaiyat is that pick 16 doesn't have.

33
00:03:49,630 --> 00:03:55,190
So you need to make sure that you take nauts again.

34
00:03:55,240 --> 00:04:02,770
Port is used to read unbought lad is used to read out to send output and pick it up while in pick 16

35
00:04:02,770 --> 00:04:09,120
of port is used to read input and output.

36
00:04:09,130 --> 00:04:10,590
That's it for this lesson.

37
00:04:10,930 --> 00:04:13,470
I will show you a simulation in the next lecture.

38
00:04:13,750 --> 00:04:14,650
Thanks for watching.

39
00:04:14,650 --> 00:04:17,940
If you have any questions please ask and the full on table.

40
00:04:18,190 --> 00:04:20,750
This is educational engineering to you.
