Sensors

light sensors may be put into active mode if desired (probably)

rotation sensors must be in active mode for proper readings
rotation sensors must also be activated with ds_rotation_on

touch sensors must be in passive mode for proper readings

These constants are defined:

LIGHT_RAW_BLACK

LIGHT_RAW_WHITE

LIGHT_MAX

DS_ALL_ACTIVE

a macro to set all sensors as active

DS_ALL_PASSIVE

a macro to set all sensors as passive

void ds_active ( SENSOR );

void ds_passive ( SENSOR );

set an individual sensor mode

Parameters:

SENSOR - must be one of the following &SENSOR_1 &SENSOR_2 &SENSOR_3

void ds_rotation_on ( SENSOR );

void ds_rotation_off ( SENSOR );

sets a sensor into rotation sensor mode

Parameters:

SENSOR - must be one of the following &SENSOR_1 &SENSOR_2 &SENSOR_3

returns:

void ds_rotation_set ( SENSOR, int i );

sets the value of a rotation sensor. Use this to initialize and calibrate your rotation sensors when your program begins.

Parameters:

SENSOR - see above - i The value to set the rotation sensor to

returns:

int TOUCH_X

macro for touch sensor X. evaluates to zero if touch sensor connected to input port X is released, and non-zero if the touch sensor is pressed.

int LIGHT_X

macro for light sensor X. evaluates to an integer between LIGHT_MIN and LIGHT_MAX

int ROTATION_X

macro for rotation sensor X. evaluates to how many 16ths of a revolution the rotation sensor has spun.

int SENSOR_X

macro for sensor X. evaluates to the raw, unprocessed value returned by the sensor connected to input port X.

int get_battery_mv ( );

returns: the battery voltage, in millivolts

int BATTERY

macro for the raw battery voltage level. use get_battery_mv instead
