Hi Kees,
you are right, the current interface does not support 16-bit registers.
We are however overhauling the I2C interface as we speak, and the
re-worked interface does have support for them (see [1]). Feel free to
take a look and comment on the proposal!
Cheers,
Hauke

Hi,
The SHT2x I2C device has a register with a 16 bits address. If I'm
correct
we don't have a function in the I2C driver to do that. Right?
Assuming we need to extend the driver API, what would be a good name
for such a function?
All I can come up with is i2c_read_regs2:
/**
* @brief Read multiple bytes from a register at the I2C slave with
the given
* address
*
* @param[in] dev I2C peripheral device
* @param[in] address bus address of the target device
* @param[in] reg the 16 bits register address on the
targeted I2C device
* @param[out] data array holding the received bytes
* @param[in] length the number of bytes to read into `data`
*
* @return the number of bytes that were read
* @return -1 on undefined device given
*/
int i2c_read_regs2(i2c_t dev, uint8_t address, uint16_t reg,
char *data, int length);
