Detailed Description

2-wire serial interface driver.

Function Documentation

void sdio_read_burst	(	uint8_t *	target_buffer,
		uint8_t	target_buffer_size
	)

Function for reading several bytes over 2-wire serial interface using burst mode.

Developer needs to implement this function in a way that suits the hardware.

Parameters

target_buffer	Buffer location to store read bytes to
target_buffer_size	Bytes allocated for target_buffer

uint8_t sdio_read_byte

(

uint8_t

address

)

Function for reading a byte over 2-wire serial interface.

Developer needs to implement this function in a way that suits the hardware.

Parameters

address

Register address to read from

Returns

Byte read

void sdio_write_byte	(	uint8_t	address,
		uint8_t	data_byte
	)

Function for writing a byte over 2-wire serial interface.

Developer needs to implement this function in a way that suits the hardware.

Parameters

address	Register address to write to
data_byte	Data byte to write
