I don't have an RGB LED-matrix or even an Orange Pi to test with, so your best bet is to hope someone else here can help you.

As I have understood, this is main difference:

which addresses similar registers ?

verify your mapping  pins gpio with :
$> gpio readall
PS: need install WiringOP

Hi ! I have the same problem.
Is there any progress with the LED matrix?  I think what need to start with a file framebuffer-internal.h There are described used GPIO

rpi-rgb-led-matrix doesn't use WiringPi.
Address of GPIO operation is being done by itself.
Substantial correction is needed.

If you rewrite this cord, it may work only a little.

https://github.com/hzeller/rpi-r ... /master/lib/gpio.cc

Because they seem to use hardware PWM.
GPIO of H3 board doesn't have the hardware PWM function.
