For a simple user interface I have to generate some beeps. At the same time, the underlaying program has to respond to interrupts for software UARTS and their like.
Does anybody have an idea how I should keep these two rather timing-intensive tasks running at once? I also consider putting up an atTiny to control just the loudspeaker from its interrupt function. Another way to go might be to get a loudspeaker with some kind of beep generator - give it some voltage and it beeps. Anybody seen such a thing?
Anyway, thanks for setting up this page. It's nice to have a forum for AVR talks.
