Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I want to generate a continuous tone for a piezo but when I use
PWM 1,3000,50
the tone is in short bursts, I have altered the duty cycle to no avail.
I remember doing it once before but forgotten how.

OK problem solved. I was using a small amplifier board and the MM signal must have been overloading it causing it to cut in and out.
