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 reading and conversion are complete, the driver will generate a * sensors_changed event. * * We use single-shot readings. In this mode, the hardware automatically goes * back to its shutdown mode after the conversion is finished. However, it will * still respond to I2C operations, so the last conversion can still be read * out. * * In order to take a new reading, the caller has to use SENSORS_ACTIVATE * again. * @{ * * \file * Header file for the Sensortag Opt3001 light sensor */ /*---------------------------------------------------------------------------*/ #ifndef OPT_3001_SENSOR_H_ #define OPT_3001_SENSOR_H_ /*---------------------------------------------------------------------------*/ extern const struct sensors_sensor opt_3001_sensor; /*---------------------------------------------------------------------------*/ #endif /* OPT_3001_SENSOR_H_ */ /*---------------------------------------------------------------------------*/ /** * @} * @} */
