Since we are developing IoT prototypes on the Orange PI platform, we have to deal with PWM signals. The Orange PI platform, by default, does not have a convenient library for working with PWM signals, so we imported the well-known library for Raspberry Pi. So we got a convenient library for Orange PI.

This library is able to modulate a software pulse width modulated signal. It is written in Python. It is used in the development of internet of things devices for the operation of a motor driver, LEDs or LED strips. But not very suitable for things like servos. Because the software PWM signal has low stability and the servo can tremble.

View, and download the library for free, you can in our repository on a github.
