Member Function Documentation

bool I2c_chibios::init

(

void

)

[virtual]

Hardware initialization.

Returns:

true Success

false Error

Implements I2c.

Here is the caller graph for this function:

bool I2c_chibios::probe

(

uint32_t

address

)

[virtual]

Test if a chip answers for a given I2C address.

Parameters:

address

Slave adress

Returns:

True Slave found

False Slave not found

Implements I2c.

Here is the call graph for this function:

bool I2c_chibios::read	(	uint8_t *	buffer,
		uint32_t	nbytes,
		uint32_t	address
	)		[virtual]

Read multiple bytes to a I2C slave device.

Parameters:

buffer	Data buffer
nbytes	Number of bytes to read
address	Slave adress

Returns:

True Data successfully read

False Data not read

Implements I2c.

bool I2c_chibios::transfer	(	uint8_t *	out_buffer,
		uint32_t	ntxbytes,
		uint8_t *	in_buffer,
		uint32_t	nrxbytes,
		uint32_t	address
	)		[virtual]

Write then Read data to/from an I2C device.

Parameters:

out_buffer	Data buffer (output)
ntxbytes	Number of bytes to write
in_buffer	Data buffer (input)
nrxbytes	Number of bytes to read

Returns:

true Success

false Failed

Reimplemented from I2c.

bool I2c_chibios::write	(	const uint8_t *	buffer,
		uint32_t	nbytes,
		uint32_t	address
	)		[virtual]

Write multiple bytes to a I2C slave device.

Parameters:

buffer	Data buffer
nbytes	Number of bytes to write
address	Slave adress

Returns:

False Data not written

Implements I2c.
