The caller must first activate the * sensor by calling SENSORS_ACTIVATE(). This will trigger the sensor's startup * sequence, but the call will not wait for it to complete so that the CPU can * perform other tasks or drop to a low power mode. * * Once the sensor is stable, the driver will generate a sensors_changed event. * * We take readings in "Forced" mode. In this mode, the BMP will take a single * measurement and it will then automatically go to sleep. * * SENSORS_ACTIVATE must be called again to trigger a new reading cycle * @{ * * \file * Header file for the Sensortag BMP280 Altimeter / Pressure Sensor */ /*---------------------------------------------------------------------------*/ #ifndef BMP_280_SENSOR_H_ #define BMP_280_SENSOR_H_ /*---------------------------------------------------------------------------*/ #define BMP_280_SENSOR_TYPE_TEMP 1 #define BMP_280_SENSOR_TYPE_PRESS 2 /*---------------------------------------------------------------------------*/ extern const struct sensors_sensor bmp_280_sensor; /*---------------------------------------------------------------------------*/ #endif /* BMP_280_SENSOR_H_ */ /*---------------------------------------------------------------------------*/ /** * @} * @} */
