#include <config.h>

/* Requires use of spi.h, and hence assumes definitions of:


	SPI_PORT		Port for the SPI signals eg PORTB
	SPI_DDR 		DDR for the SPI signals eg DDRB
	SPI_PIN 		Input Port for the SPI signals eg PINB

	SPI_SCK 		Clock from master to slave
	SPI_SEND   		Data from Master to slave
	SPI_RECV   		Data from slave to master



Additionally, the following needs to be defined:

	RAM_CS
	RAM_PORT
	RAM_DDR
