Can BS2 run >1 speaker at once?

John Kauffman

Using a BS2 is there a way to run three peizo speakers on three pins at once to make a chord? I've done tons of single-speaker projects but I can't picture how to interleave three FREQOUTs. (I know that is why there is a Propeller... but possible in BS2?)

No, although FREQOUT can produce two tones at a time on one I/O pin. The Stamps are "single threaded" processors. They do only one thing at a time. When a FREQOUT executes, the Stamp can't do anything else until the FREQOUT is done.

Another idea - if you have some extra Stamps, yes. I built this ten stamp machine and did one experiment to make ten part chord music using all piezo speakers.
