/**

|
|
* Header file for the reed sensor
|
||
|
|
*
|
||
|
|
* The Reed sensor allows to be used either by polling the sensor status or by
|
||
|
|
* setting up a timer on the background ticking every REED_CHECK_PERIOD, posting
|
||
|
|
* a reed_sensor_event_changed event, informing the application about a change
|
||
|
|
* in the sensor status (basically open or closed). To enable each mode
|
||
|
|
* (default is polling) call the configure() function with REED_SENSOR_MODE
|
||
|
|
* using REED_SENSOR_EVENT_MODE or REED_SENSOR_POLL_MODE, after having
|
||
|
|
* initialized the device using SENSORS_ACTIVATE(reed_sensor).
