Example #1

static int lm75_writeb16(FAR struct lm75_dev_s *priv, uint8_t regaddr,
                         b16_t regval)
{

  /* Set up a 3 byte message to send */

  buffer[2] = (uint8_t)regb8;

  /* Write the register address followed by the data (no RESTART) */

  return lm75_i2c_write(priv, buffer, 3);
