Function Documentation

sensirion_i2c_init()

void sensirion_i2c_init

(

void

)

Driver file does not know about the board configuration, use ri_i2c_init instead.

sensirion_i2c_read()

int8_t sensirion_i2c_read	(	uint8_t	address,
		uint8_t *	data,
		uint16_t	count
	)

Execute one read transaction on the I2C bus, reading a given number of bytes. If the device does not acknowledge the read command, an error shall be returned.

Parameters

address	7-bit I2C address to read from
data	pointer to the buffer where the data is to be stored
count	number of bytes to read from I2C and store in the buffer

Returns

0 on success, error code otherwise

Definition at line 96 of file ruuvi_interface_i2c_shtcx.c.

sensirion_i2c_release()

void sensirion_i2c_release

(

void

)

Release all resources initialized by sensirion_i2c_init().

Definition at line 80 of file ruuvi_interface_i2c_shtcx.c.

sensirion_i2c_select_bus()

int16_t sensirion_i2c_select_bus

(

uint8_t

bus_idx

)

Select the current i2c bus by index. All following i2c operations will be directed at that bus.

THE IMPLEMENTATION IS OPTIONAL ON SINGLE-BUS SETUPS (all sensors on the same bus)

Parameters

bus_idx

Bus index to select

Returns

0 on success, an error code otherwise

Definition at line 62 of file ruuvi_interface_i2c_shtcx.c.

sensirion_i2c_write()

int8_t sensirion_i2c_write	(	uint8_t	address,
		const uint8_t *	data,
		uint16_t	count
	)

Execute one write transaction on the I2C bus, sending a given number of bytes. The bytes in the supplied buffer must be sent to the given address. If the slave device does not acknowledge any of the bytes, an error shall be returned.

Parameters

address	7-bit I2C address to write to
data	pointer to the buffer containing the data to write
count	number of bytes to read from the buffer and send over I2C

Returns

0 on success, error code otherwise
