Newbie: Can't get ColorSensor samples to receive their data
Hi all! I'm just getting started with Mindstorms and RobotC, and I'm particularly interested in the ColorSensor. I can get it to work fine when I run e.g. View -> Color Detector (on the NXT display), or when I use the visual Mindstorms bricks editor. However, I want to use RobotC, but trying different samples I cannot seem to receive data (neither is the light of the sensor turned on when running them, if that matters). For instance, running the sample listed at the top of viewtopic.php?f=19&t=2526
will show, on the display, the string "???", even though I'm holding the sensor (port 3) over green.
Some background: I'm using Mindstorms Next 2.0. In the RobotC IDE, I did the suggested Firmware update; the About dialog now reads RobotC3.04 (F/W 9.04). I'm on Windows 7.
Thanks for any help!!
