|
|
*
|
|
* Due to the time required for the sensor to startup, this driver is meant to
|
|
* be used in an asynchronous fashion. 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.
|
|
*
|
|
* The caller should then use value(TMP_007_SENSOR_TYPE_ALL) to read sensor
|
|
* values and latch them. Once completed successfully, individual readings can
|
|
* be retrieved with calls to value(TMP_007_SENSOR_TYPE_OBJECT) or
|
|
* value(TMP_007_SENSOR_TYPE_AMBIENT).
|
|
*
|
|
* Once required readings have been taken, the caller has two options:
|
|
* - Turn the sensor off by calling SENSORS_DEACTIVATE, but in order to take
|
|
* subsequent readings SENSORS_ACTIVATE must be called again
|
|
* - Leave the sensor on. In this scenario, the caller can simply keep calling
|
|
* value(TMP_007_SENSOR_TYPE_ALL) to read and latch new values. However
|
|
* keeping the sensor on will consume more energy
