High Frequency Precision Sine Wave Synthesis for the Arduino by Adrian Freed
While researching something completely different, I found Adrian Freed’s very cool page with code to generate high quality sine waves using PWM on the Arduino. This code could serve as an audio frequency signal generator, or as the basis of a computer music project. It also demonstrates some non-trivial Arduino wizardry in dealing with PWM interrupts and the like. Bookmarked for future reference!
I recall burning three or four weeks of a sabbatical getting Saccade.com on the air with Wordpress. So much tweaking…
