02:09 PM FozzWorth: I'm working on a signal generator based on an AD9833, controlled by a m328p. This isn't avr related so much as it is just my failure to understand the datasheet/electronics. All is working with my crude waveform and frequency selection strategies, but I'm trying to understand why peak to peak voltage for sine and triangle waveforms runs right around 800mV, but when I switch to square wave output, pk-to-pk jumps to right about Vcc. I'm using Vcc from USB.

02:10 PM FozzWorth: All of that aside, I guess my real question is how can I tame this 5v square to match the other two amplitudes, which I think could be AVR related, e.g trigger a gate to regulate the voltage when square wave is active and bypass when it's not?
02:11 PM FozzWorth: Here's my (likely flawed) code, if anyone is willing to have a look.
