light_sensor_enable, light_sensor_disable
light_sensor_get_value

light_sensor_enable

NAME

   light_sensor_enable, light_sensor_disable -- enable and disable the light sensor measurements

SYNOPSIS

  #include <device/light_sensor.h>

   void light_sensor_enable (DeviceTag sensor, guint16 ms);
   void light_sensor_disable (DeviceTag sensor);

DESCRIPTION

light_sensor_enable allows the user to enable a light sensor measurement each ms milliseconds.

light_sensor_disable turns the light sensor off, saving computation time.

light_sensor_get_value

NAME

   light_sensor_get_value -- get the light sensor measure

SYNOPSIS

  #include <device/light_sensor.h>

   guint16 light_sensor_get_value (DeviceTag sensor);

DESCRIPTION

light_sensor_get_value returns the last value measured by the specified light sensor. This value is computed by the simulator according to the lookup table of the LightSensor node. Hence, the value range for the return value is defined by this lookup table.
