I do not have the mindsensors DROD-Nx sensor but I have read the documentation
from their website. It says that the sensor is an analog sensor which you can
read using the standard NXT-G light sensor block. That means you need to
configure the sensor port as an active light sensor and then simply read its
value.
I also compiled a simple NXT-G program containing one DROD sensor block and
examined the decompiled .rxe file using BricxCC. It shows that the
mindsensors.com block uses the NormalizedValue sensor reading. So in NXC you
can simply do this:
task main() {
SetSensorType(S1, SENSOR_TYPE_LIGHT_ACTIVE);
SetSensorMode(S1, SENSOR_MODE_PERCENT);
ResetSensor(S1);
while (true) {
NumOut(0, LCD_LINE1, SensorNormalized(S1), true);
Wait(100);
}
}
Hope this helps,
John Hansen

Anyway, that is sort of what I tried (I changed the original program so many times I am not sure). But probably I missed (...) (17 years ago, 27-Nov-07, to lugnet.robotics.nxt)
