There is a new PWM driver available (it uses UART0_RX pin on the UART breakout header):

I made PWM C Library for H3/H2+ Sunxi SoC.
And it can control using command line(pwmc).

The port which can be used in PWM0 is UART0_RX.
UART0_RX (PA5) is middle pin of the UART header.
Locating the UART header is here.

But acording with this document, the PWM port is:but i can not find the way to control, for example ...
I have a data seat of H3 here.

There is an explanation of PWM in P74, but there are no functions of PWM in PA6.

You can use 16 Channel 12-bit PWM/Servo Driver-I2C interface of PCA9685.It's only $1.8

Yes, but then, what about this:
PA6 (SIM_PWREN/PWM1/PA_EINT6)


I think this is a mistake.

Have a look at the examples also.

Hi all, I forked PiZyPWM library, so now we got Python PWM library for Orange PI. Tested on Orange Pi Lite with motor drivers. Feel free to use and fork https://github.com/evergreen-it-dev/orangepwm
