Marconi??????
Tesla!!!

If you do not figure it out in a bit. Post the configs/code and tell us again how everything is connected.

Being that it returned something once makes me think something might be loose.

Well it could be. Although I've just realised that it only posted the 'yyyyy's when I reloaded the program.

Speaking of program, could that be the problem (don't forget I'm still the worst programmer in the Northern hemisphere right now)

CMCON0 = %00000111 
ANSEL = %00000000 
TRISIO = %00000000 
GPIO = %00000000
 
DEFINE SER2_BITS 8

MYVAR  VAR BYTE 
 
MAIN

serin2 GPIO.0, 2400,[DEC MYVAR] 

IF MYVAR = 3 THEN HIGH GPIO.5

Hint...

serin2 GPIO.0, 2400,[DEC MYVAR]

Take another look at the manual and appendix B , I think it is B, MODE number.

Then add a short pause maybe 1/4 second, and a GOTO MAIN

MAIN:

I've tried this but it doesn't compile, do I need the 2400baud as well?

serin2 GPIO.0, Mode = 396, [DEC MYVAR]

From the manual

' Wait until the character “A” is received serially on Pin1 and put next character into B0
SERIN2 1,16780,[wait (“A”),B0]

' Skip 2 chars and grab a 4 digit decimal number
SERIN2 PORTA.1,84,[skip 2,dec4 B0]

SERIN2 PORTA.1\PORTA.0,84,100,tlabel,[wait (“x”, b0), str ar]

This was my last go for tonight (wouldn't compile though).

I'm going to sleep on it.

Cheers again mackrackit, see you tomorrow.

Might be another problem...

If all of the PicKIt1 are the same, mine has GPIO.0 connected to the on-board POT (RP1).

Your code is still a bit off, but code will not fix hardware.

Maybe I am looking at the hardware wrong, exactly what do you have? Maybe a picture?

Hi mackrackit,

I've re-cheched my connections:

PIC12F683 on my PICKit1.

I've got common pin5 on the DB9 cable (yellow) going to VSS PIC pin8.

I've got pin3 on the DB9 cable (red) going to GPIO.0 PIC pin7.

And pin2 on the DB9 cable (brown) going to GPIO.2 PIC pin5.

Pin 5
Common, ground, zero rail...
This must be connected to both devices for any serial to work.

Pin 2
Data is sent to the PC via this pin. PIC® -->> PC

Pin 3
Data is sent to the PIC® via this pin. PIC® <<-- PC

So data is coming from the pc onto GPIO.0

data is going from the PIC to pc on GPIO.2

How does that look / sound?

Dave
