Three different master-slave SPI examples implemented for the PIC18F and PIC32MX - barebones, using interrupts and with slave returning data. PICs are used as both master and slave.

Just released my first libstock example, the SPI master slave party pack!

This pack contains three different master-slave SPI examples. All examples have been implemented on both the PIC18F and the PIC32MX, and though they have only been tested with different master and slave MCUs (PIC18F as master and PIC32MX as slave or vice versa), they should also work between two MCUs from the same family (famous last words...).

The PIC18F has been tested with a PIC18F458 running at 20MHz (NB - not default crystal) on an EasyPIC3.
The PIC32MX has been tested with a PIC32MX795F512L runnint at 80MHz on an EasyPIC Fusion v7

The three examples are as follows:

1) Simple master/slave
=========================
A barebones master sending data that is received by an absolutely minimal slave. This example will let you confirm that your setup works as it should without starting to mess around with interrupts etc. It is however probably not what you want to use in real life.

Projects needed:
  Master: PIC18F SPI master or PIC32MX SPI master
  Slave: PIC18F SPI slave or PIC32MX SPI slave

2) Simple master/slave with interrupts
========================================
A barebones master sending data that is received by slave that detects input using interrupts. This is way more efficient and is a nice building block if you want a slave that receives commands witout responding to them, like a motor controller or led sign output controller etc.

Projects needed:
  Master: "PIC18F SPI master" or "PIC32MX SPI master"
  Slave: "PIC18F SPI slave" with interrupt or "PIC32MX SPI slave with interrupt"

3) Master/slave with two way data transfer
============================================
A master that can read data back from the slave and a slave that returns data when it receives a 'get data' command. This will let you build a slave that can return a reading, internal state etc.

Projects needed:
  Master: "PIC18F SPI master reading slave response" or "PIC32MX SPI master reading slave response"
  Slave: "PIC18F SPI slave" with response or "PIC32MX SPI slave with response"
