Hello,

I Have a PC with IO expansion card that can be accessed with outb and inb function from sys/io.h

I want these outputs as PWM signals, the task is not very time critical so I choose to go software PWM (bit banging)

I found out that lot of soft PWM codes (RPI, beaglebone) are actually kernel modules not a typical node.

What do you believe it would be the Best Practise?

does anyone ever used sysfs pwm
