Re: [avr-gcc-list] sine wave generator.

Hi,
How accurate does the sine wave need to be? (ie. what levels of
distortion are acceptable?)

The non-constant frequency shouldn't make the PWM not work.

However, a modification that you might like to consider would be
creating a software sigma-delta, using an output pin as a software
controlled PWM, and sampling the voltage on the resistor/capacitor using
an on-board ADC. (of course, this depends on the avr device that you're
using)

Hope this helps,
