I guess the module IS bad because your app responds like mine...no error and no action.
I am trying to do a demo for my students using Omar's sample of the RGBLed. I am using VS 2010, netfw 4.2 and the board is using 4.2 also. Deploys fine but no response from led. Changed cables, no help.
Do I have to update the Go board to 4.2.2?
Running the latest firmware is typically always a good idea.
That said...can you share the code you're using? And tell us which line of code is stopping the program in its tracks, what error you get, etc.?
Do you have VB 2010 installed?
Do you have the RGB LED module plugged into port 8?
Please try moving it to another port, and updating the "new NetduinoGo.RgbLed" constructor with the new port #.
We test each module before shipping them out, but it is possible for things to get damaged or more rarely for defective parts to become bad in-field. We'd be interested in swapping you for another RGB LED module--if the above doesn't fix the issue for you--to figure out what went wrong.
