So why going PWM?
Just use one output port and 8 sigma-delta sequenced on a fast interrupt.
BTW the Mega AVRs have 4 timers: 2x8 bits with 1 OCR each, and 2x16 bits
with 3 OCR each, giving you the wanted 8 PWM output if you don't like
the better SD
Hello Spehro,
Currently I am looking at the MSP430. There is only one timer on most of
these, with 2-3 CCRs. If it doesn't have to do anything else I could add
more in assembler. The need to listen to some kind of bus for value
changes throws that a curve though. Plus in this case I'd have to filter
them LC because the wee corners of an RC need to be muffled. Has to be
whisper quiet.
