Hello,

I have a few stm32f1 around but i am in doubt if them would perform really better then the avr

From your account i see that you made both the mega version then this. Which is your experience about? The more powerful stm32 outperform the tiny 8bit? Which would you suggest for a new design?

Yes it is far better than the AVR. The step rate can go up to 180Khz while AVR can only do 33Khz.
