Value:

i2cMasterTransmitTimeout(i2cp, sad, txbuf, n + 1, NULL, 0, \

TIME_INFINITE)

i2cMasterTransmitTimeout

msg_t i2cMasterTransmitTimeout(I2CDriver *i2cp, i2caddr_t addr, const uint8_t *txbuf, size_t txbytes, uint8_t *rxbuf, size_t rxbytes, sysinterval_t timeout)

Sends data via the I2C bus.

Definition hal_i2c.c:187

TIME_INFINITE

#define TIME_INFINITE

Infinite interval specification for all functions with a timeout specification.

Definition chtime.h:55

Writes a value into a register using I2C.

Precondition: The I2C interface must be initialized and the driver started.

Parameters

[in]	i2cp	pointer to the I2C interface
[in]	sad	slave address without R bit
[in]	txbuf	buffer containing sub-address value in first position and values to write
[in]	n	size of txbuf less one (not considering the first element)

Returns: the operation status.

Function Class:: Not an API, this function is for internal use only.
