Re: [PIC]: ASM in Hi-Tech C error

Howdy,

I had issues using the SPI port as well.  From memory I had to read the
SSPBUF register first (even though the data was meaningless) using "movf
SSPBUF, W", then I was able to write to the register without causing a
write collision.  My application was entirely in assembly however so I'm
not sure about the compiler your using.  Oh by the way this was using a
PIC18F452, I'm not sure about other models with SPI interfaces.

Sincerely
