Hi all,
I am trying to caluclulate maximum light level reading from the light sensor
but all I get is 88 or 87 as the number displayed on the LCD. It appears
after doing some tests that the first value the readValue() method picks up
is 88 or 87 at any lighting condition.
My code is shown below. Any help is appreciated.
Thanks.
---------------------------
import josx.platform.rcx.*;
public class LightSeeker {
public static void main(String[] args)
throws InterruptedException {
int max_val = 0;
int current_val;
Sensor.S1.setTypeAndMode(SensorConstants.SENSOR_TYPE_TOUCH,
SensorConstants.SENSOR_MODE_BOOL);
Sensor.S2.setTypeAndMode(SensorConstants.SENSOR_TYPE_LIGHT,
SensorConstants.SENSOR_MODE_PCT);
Sensor.S2.activate();
while(Sensor.S1.readBooleanValue() == false) // touch sensor is
not pressed
{
current_val =
Sensor.S2.readValue();//Sensor.S2.readSensorValue(1,1);
if (current_val > max_val){
max_val = current_val;
}
} // while loop
Sensor.S2.passivate();
Sound.beep();
LCD.showNumber(max_val);
Button.RUN.waitForPressAndRelease();
}
}
