bool Spi_stm32::init

(

void

)

[virtual]

Hardware initialization.

Returns:

true Success

false Error

Implements Spi.

Here is the caller graph for this function:

bool Spi_stm32::read	(	uint8_t *	in_buffer,
		uint32_t	nbytes = 1
	)		[virtual]

Read bytes from the spi line.

Parameters:

bytes	Incoming bytes
nbytes	Number of bytes to read

Returns:

true Data successfully read

false Data not read

Implements Spi.

Here is the call graph for this function:

bool Spi_stm32::transfer	(	uint8_t *	out_buffer,
		uint8_t *	in_buffer,
		uint32_t	nbytes
	)		[virtual]

Write and Read data to/from the SPI bus.

Parameters:

out_buffer	Data buffer (output)
in_buffer	Data buffer (input)
nbytes	Number of bytes to write/read

Returns:

true Success

false Failed

Implements Spi.

Here is the caller graph for this function:

bool Spi_stm32::write	(	uint8_t *	bytes,
		uint32_t	nbytes = 1
	)		[virtual]
