Hello Onlaj.

Now my raspberry pi does it work and detect my piano (CASIO PX-130) you can see the OS show massages (see in a pic)

I try to press some piano keys and then i can see LED light up on WS8212B as white color but the 1.44inch LCD hat always white screen so i can't control menus for select other colors (see in a clip vdo)

Hello.
Can you connect to webinterface? You can control your settings from there.
As for screen, try to run /tests/test_screen.py
If it doesn't show anything on your screen, try to unplug strip's wires (as well as your extension board) from your RPi and run script again.

Hello Onlaj, Thank for answer me.
I don't know how to open the webinterface, how to open it ?
I tried to execute 'test_screen.py' file and it works in case the LCD hat connect to Raspberry pi board directly :).
