Data Structures
struct	bar_bmp585_t
	Measurement data produced by the BMP585 barometric pressure sensor. Populated by bar_bmp585_Read(); check IsDataValid before use. More...

Functions
int8_t	bar_bmp585_Is (I2C_HandleTypeDef *hi2c, int8_t tryInit)
	Check if sensor is present.
HAL_StatusTypeDef	bar_bmp585_Init (I2C_HandleTypeDef *hi2c)
	Initialize sensor, check if it really is this sensor. After check the sensor is turned off to save power.
HAL_StatusTypeDef	bar_bmp585_On (I2C_HandleTypeDef *hi2c)
	Turn on sensor - wakeup the sensor and start to processing of pressure measure.
HAL_StatusTypeDef	bar_bmp585_Off (I2C_HandleTypeDef *hi2c)
	Turn off sensor - stop measure and put sensor in very deep sleep mode.
HAL_StatusTypeDef	bar_bmp585_Read (I2C_HandleTypeDef *hi2c)
	Read value from sensor, pressure and temperature. Sensor must be turned on before.
