|
|
Each sensor has a set of functions for controlling it and query it for
|
|
|
|
|
its state. Some sensors also generate an events when the sensors
|
|
|
|
|
change. A sensor must be activated before it generates events or
|
|
|
|
|
relevant values.
|
|
|
|
|
|
|
|
|
|
- SENSORS_ACTIVATE(sensor) - activate the sensor
|
|
|
|
|
- SENSORS_DEACTIVATE(sensor) - deactivate the sensor
|
|
|
|
|
- sensor.value(0) - query the sensor for its last value
|
|
|
|
|
|
|
|
|
|
- \ref sensors_event - event sent when a sensor has changed (the data
|
|
|
|
|
argument will referer to the actual sensor)
|
|
|
|
|
|
|
|
|
|
Example for querying the button:
|
|
|
|
|
|
|
|
|
|
- \ref SENSORS_ACTIVATE(button_sensor) - activate the button sensor
|
|
|
|
|
- \ref button_sensor.value(0) - the button has been pressed or not
|
|
|

Contiki provides a set of timer libraries. Event timers generates an
|
|
|
|
|
event when the timer expires and callback timers call a function when
|
|
|
|
|
the timer expires. The simple timers on the other hand have to be
|
|
|
|
|
actively queried to check when they have expired.
