Hi all,
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?
best! d.
