PIC to PIC communication problem

That's for sure. SHIFTIN act as master, not slave. you'll need to roll your own.

Possible to use the MSSP module as well. Have a look to SPISlave.bas
http://www.melabs.com/resources/samp...p/spislave.bas

You could still implement a simple serial communication with DEBUG/SEROUT2/HSEROUT... just an idea.

PS:

Code:

@Config = _XT_OSC & _WDT_OFF & _PWRTE_OFF & _LVP_OFF & _BODEN_OFF
Define PIC16F877A

You don't need to define the PIC, and you config line is incorrect. it should be

Code:

@  __CONFIG _XT_OSC & _WDT_OFF & _PWRTE_OFF & _LVP_OFF & _BODEN_OFF
