I’m experimenting with my NANO, and i just discovered the pwm pins, and its management through sysfs.
I’d like to use the pwm pin (for example pwmchip0) as a pwm audio signal, and treat my nano as a digital audio synth.
I know it would sound bad, but it’s just for fun :)
The main problem is the frequency rate.
Is it possible to “force” the pwm signal in a range between 20 Hz and 20Khz?
