hey jamisnemo. i'm interested in your code to generate square and triangular signals. i don't care too much about the higher freqs so i'd be fine with the ~31k freq of the pwm and a low pass at 30k. if you don't mind sendin your code, you can email me at tateu@yaoo.com.
i would like to generate audio from the arduino, eventually, my goal is to do some ADC on some audio on analog pins, screw with it and output it back with pwm. i've looked a bit into generating sq signals but got nowhere so far.
thanks in advance for your help.
tateu.
