Hitechnic Color Sensor

[john rieffel]

Hi There,

I have a hiechnic color sensor that I'm trying to configure. The
following code doesn't seem to ever return a non-zero number:

myColor = Color20(myRobot,PORT_3)
print myColor.getSample()

advice?

Hi John,

My students had the same problem with the ultrasonic sensor, and they
solved it by calling get_single_shot_measurement() instead of
getSample(). Perhaps the same thing would work for the color sensor.
There is also a get_sample() method in the superclasses for these
sensors, so you might try that.

Best,
Simon

eer, i meant get_sample. which doesn't return non-zero

I'll try get_single_shot_measurement()

follow up: I was able to get values from the following code:

from nxt.sensor.hitechnic import *
myColorSensor = Colorv2(myRobot,PORT_4)
val = myColorSensor.get_sample()
print val.red, val.blue, val.green

is this the best way to go about it?

Try HTColorv2...Color20 is the NXT 2.0 official color sensor.

Didn't it warn that you were using the wrong sensor?
