using Pduino as a CV generator for my modular. First problem is to make
a low pass filter circuit to remove the PWM noise and get smooth DC out.
Might be helpful to know the default PWM frequency. I know it's set in
the firmware, but I've read everything from 450 Hz to 32 Khz, and
several other numbers in between out there in Googleland. I'm using
Arduino 0011 and the Arduino NG board (ATMega8 controller). Anyone have
the definitive answer?
