Function Documentation

void spi0_hard_init_master ( void )

Initializes the AVR hardware SPI for spi0.

uint16_t spi0_hard_master_rw16 ( uint16_t to_slave )

Writes and reads a 16-bit word via hardware SPI for spi0.

Parameters:

to_slave

- 16-bit word to send to the slave device.

uint8_t spi0_hard_master_rw8 ( uint8_t to_slave )

Writes and reads an 8-bit byte via hardware SPI for spi0.

Parameters:

to_slave

- 8-bit byte to send to the slave device.

void spi0_init_master ( void )
