Timer0 has been used by arduino In NANO, what about NANO every?
TCA has been requisitioned?
How to output 40K HZ PWM in NANO every?
I think it is better to use TCB, for there are 4 of it.
But I don't know how to get it.
With 8 bit PWM mode, what I get is like this:
the counter is 16 bits and the CCMPL/CCMPH is 8 bits, it just output half PWM :)
