\section sensors Sensor functions
|
|
|
|
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
|
|
|
|
\subsection quickref-sensors Sensor on the ESB platform
|
|
|
|
- \ref battery_sensor - query the battery voltage level
|
|
- \ref button_sensor - query the on-board button
|
|
- \ref pir_sensor - query the passive IR sensor (motion detector)
|
|
- \ref radio_sensor - query the radio signal strength
|
|
- \ref sound_sensor - query the microphone
|
|
- \ref temperature_sensor - query the temperature sensor
|
|
- \ref vib_sensor - query the vibration sensor
|
|
|
|
\section quickref-leds LED functions
|
|
|
|
- leds_on() - turn LEDs on
|
|
- leds_off() - turn LEDs off
|
|
- leds_invert() - invert LEDs
|
|
- leds_blink() - blink all LEDs
|
|
|
|
\section quickref-beeper Beeper functions
|
|
|
|
- beep() - click the beeper
|
|
- beep_beep() - beep
|
|
- beep_down() - pitchbend down beep
|
|
- beep_quick() - a number of quick beeps
|
|
- beep_spinup() - pitchbend up beep
|
|
|
|
\section quickref-timers Timer functions
|
|
|
|
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.
|
|
|
|
\subsection quickref-etimer Event timers
|
|
|
|
- etimer_expired() - check if an event timer has expired
|
|
- etimer_set() - set an event timer
|
|
- etimer_reset() - set an expired event timer to the next interval
|
|
- etimer_restart() - restart an event timer from the current point in time
|
|
|
|
\subsection quickref-ctimer Callback timers
|
|
|
|
- ctimer_expired() - check if a callback timer has expired
|
|
- ctimer_set() - set a callback timer
|
|
- ctimer_reset() - set an expired callback timer to the next interval
|
|
- ctimer_restart() - restart a callback timer from the current point in time
|
|
|
|
\subsection quickref-timer Simple timers
|
|
|
|
- timer_expired() - check if a simple timer has expired
|
|
- timer_set() - set a simple timer
|
|
- timer_reset() - set a simple event timer to the next interval
|
|
- timer_restart() - restart a simple timer from the current point in time
