433MHz RF PIC2PIC connection

Hi Ralph,

Done. Works perfectly.

Receiving on 18F452

DEFINE OSC 20
DEFINE LOADER_USED 1
myVar VAR byte[32]


BEGIN:
SERIN2 PORTB.0,16468,1000,TIME_OUT,[STR myVar\32\13]
HSEROUT [STR myVar\32,13,10] ' Display result
CLEAR ' Clear array
GOTO BEGIN

TIME_OUT:
HSEROUT ["Time Out",13,10] ' Indicate timeout
GOTO BEGIN

Sending with 16F876A

DEFINE OSC 20
DEFINE LOADER_USED 1

BEGIN:
SEROUT2 PORTB.0,16468,["-- Hello there this is a test --",13]
PAUSE 1000
GOTO BEGIN

18F452 connected to PC serial port returns the following in MCS+ terminal program: -- Hello there this is a test --

Dissconnect 16F876A from 18F452 serial input, ground 18F RB0, returns Time Out. Float or take RB0 HIGH, sit & spin in the SERIN2 line.

Tried similar routines via RF. Still works flawlessly. Tossed in a few bytes to DC balance the receiver data-slicer, but I get similar good results.

Ran same tests with the WAIT modifier. Same results.

I suspect something else may be causing your headaches.
