I am trying to determine how to get accurate color representation of RGB values with a Netduino's PWM inputs. Specifically, I had worked with an Arduino and the range of the PWM inputs was 0 to 255. On the Netduino, the range is 0 to 100. I want to be able to generate colors based on a scale of 0 to 255 for red, green, and blue. I was able to do this easily with the Arduino. You can see my video of RGB LED color generation with an Arduino. I am unsure how to do this with Netduino. I know that there is a SetPulse and SetDutyCycle function, but I can't seem to figure out how to get a range of 0 to 255 so that I can represent monitor RGB LED values. Any help is greatly appreciated.

Firstly, welcome to the community.

There is a forum posting on PWM here. I found this useful when I played around with this earlier in the year.

Pete Brown has also written a post onthe subject and that can be found on his blog.

Hope this helps,
