Functions
static int8_t	cal_crc (uint8_t seed, uint8_t data)

static void	parse_sensor_data (const uint8_t reg_data, struct bmp3_uncomp_data uncomp_data)
	This internal API is used to parse the pressure or temperature or both the data and store it in the bmp3_uncomp_data structure instance. More...

static int64_t	compensate_temperature (const struct bmp3_uncomp_data uncomp_data, struct bmp3_calib_data calib_data)
	This internal API is used to compensate the raw temperature data and return the compensated temperature data in integer data type. For eg if returned temperature is 2426 then it is 2426/100 = 24.26 deg Celsius. More...

static uint64_t	compensate_pressure (const struct bmp3_uncomp_data uncomp_data, const struct bmp3_calib_data calib_data)
	This internal API is used to compensate the raw pressure data and return the compensated pressure data in integer data type. for eg return if pressure is 9528709 which is 9528709/100 = 95287.09 Pascal or 952.8709 hecto Pascal. More...
