Please share the solution: using FYSETC 12864 RGB Mini panel overrides SKR 1.4 Turbo "RGB" pin control (1_24 pin). Command M150 R..G..B.. I.. doesn't help, M150 controls only LCD Panel instead of both LED stripe and LCD.
There is example firmware for SKR 1.3 here, you can change the config for SKR 1.4 and have a test. And please read the README.md first
