Nice work! I always love a good PWM square wave!
I have designed a CPU replacement for the Poly-800 based on the STM32
F4. I have the board designed but not built or tested yet. It will
replace the HAWK kit completely.
It is not yet designed to do any tone generation. But once I get into
it, I plan on replacing the MSM5232 with another STM32 F4 board as
well. And that will definitely be producing sound and will have digital
filters as well.I like what you're doing and maybe you would like to do the sound board
for the Poly? You obviously have the technical chops for it.
