SERIN AND SEROUT PROBELM USING 16f690 PIC

[skimask]

Q: What sets the valid in the RX code?
A: Nothing.

So the program is doing exactly what you set it up to do...nothing but sit in a stuck loop. Which loop? Your turn to figure that one out. Hopefully it doesn't take you 2 weeks to do that. Maybe ask your instructor for some instruction on how to follow basic logic from start to finish...or in this case, from start to stuck...

what sets the valid in Rx is the dgood(pin) from transmitter so whenever the key pressed, the dgood become low and it is connected through wire to the valid pin in receiver so it will go out from the wait loop and display...
the thing is all goes well accept the value inside the num(register) is 0 when i display..is the way i use the serin and serout is correct?...do u have any suggestion..thanx very much

Ok, back to you again, what sets valid = 1 or valid = 0?

[Charles]

in the transmitter part
u see the dgood pin..it is connected to valid pin in receiver...
therefore whenever i press the keypad, dgood become low which indicate valid =0...therefore it will goes out from the wait loop (in the receiver part) and display the number inside

Hey Charles, you suppose we could see a schematic? It sort of looks as if you want to send serial data from one pic to the other, hence skimasks question, but if you have everything all hardwired together, then we need to see how.

dgood (portB.4) from PIC1 i connect it to valid(portB.6) from PIC2...sorry there is a mistype in the code it should be valid var portB.6 not valid var byte...then otupin(portB.7) from PIC1 is connected to keyinput(portB.5) from PIC2)/....yup i'm trying to send data serially from pic1 to pic2...any suggestion?thanx very much...

best regards

Yes, but on the receiver side, valid is a BYTE, not a Pin.

So back to skimask's question,
"What sets the valid in the RX code?"

But he's only got TWO WEEKS!!!! AAAaaaaaaaaaaaaa.............

Easy skimask, Down boy, Down!

Let me take this one ...

I'm always skeptical when someone Cut&Pastes their entire program into a Post.
And, the one thing that points out a definate cause of the described problem suddenly turns into a "typo".

In the middle of a Cut&Paste? Come on!

See, I can do it too.

Ok well, my advice is to dump the keypad routine, and use this...

Not exactly what you are doing, but the concepts are the same. Just 2 PIC's instead of many.

The output my program right now when i display on the lcd is

ENTER POLARITY
1)+ 2)- 0(this zero should be number that is pressed on the keypad)
