Hi mackrackit

Yes, I told you to use DISABLE-ENABLE-RESUME... I thought you were playing with ONINTERUPPT.

I did and I am still hoping to get it working: Post #893 above has ON INTERRUPT -DISABLE-ENABLE-RESUME in the code.

Thanks for the TX program, I had to change:

@DEVICEPIC12F675,MCLR_OFF,INTRC_OSC_NOCLKOUT,WDT_OFF,BOD_OFF
@ DEVICE PWRT_ON,PROTECT_OFF

To:

@ __config _INTRC_OSC_NOCLKOUT & _WDT_OFF & _MCLRE_OFF & _CP_OFF & _BODEN_OFF & _PWRTE_ON

To make the program compile, are the above changes ok?

So what happened when I ran it? Well the RFEN led lit for five seconds immediately either button was pressed but nothing was transmitted. I then commented out the delay loop, the RFEN led lit when buttons pressed then went off when button released - still no data sent.

I see where you're coming from with the IF - THEN with the program then going onto the ENDIF statement.

I made a small change adding:

IF (GPIO.3=1) AND (GPIO.4=1) THEN goto   Main
 if (GPIO.3=0) OR (GPIO.4=0) THEN 'Look for ENDIF

The result was the RFEN led lit for five seconds immediately either button was pressed but nothing was transmitted (as before) however, when the delay loop was commented out data was trnsmitted.

It seems to me that the delay loop is killing the data transfer. What do you think?

But first you may want to try Bruce's code as he wrote it to make sure your hardware is working correctly.

I've saved Bruce's original code as Tx - Rx Master, works a treat.
