Hi all,

I'm using the SPI feature on a 16f877.

 

Does anyone know how I would go about accessing memory location 0x80 of a slave device and writing or reading the contents of sspbuf to or from it?

 

I can read and write to the slave at the moment, but I need to read / write to specific memory locations.

 

Regards,

Daz.

The same way you would if it were a direct program in the chip, only the interface handling changes.

 

eg. for a read you send an SPI command that the pic recognises, the pic then processes it, then sends data back.
