pic spi example

Hi all

I need an example code for SPI interface for PIC microcontroller using C18 compiler, if you have a code working please post it, i don't need it for college project but i'm facing some problems with SPI interface and need a reference code to follow.

Thanks in advance

spi code for pic

Actually, I have the same question.

Specifically, I have read through the examples given, and I was wondering if there is common syntax for the C18 compiler for the following:

1) SPI read(char)
2) SPI write(char)

I ask because I see several commands in the postings, but I am unsure if they are standard, or written in code not shown there. I just need to send bytes of data to an external device using SPI interface.

Does anyone know of an API which has commands useful to micro-controllers using the C18 compiler?

I just need some simple commands, I can initialize the registers and SPI mode myself from the PIC datasheet.

Thanks in advance
