BTT TFT24-V1.1 does not work in Marlin mode

Recommended Posts

Hi everyone,
I'm trying to connect a BTT TFT24-V1.1 display to an SKR 1.4 board. The wiring is as follows.



Serial communication occurs correctly.
I tested Marlin mode 12864 by inserting the following code into the Marlin firmware.

#define ST7920_DELAY_1 DELAY_NS(200) // After CLK LOW
#define ST7920_DELAY_2 DELAY_NS(500) // After DAT
#define ST7920_DELAY_3 DELAY_NS(500) // After CLK HIGH

And I selected Marlin Mode Type 128x64 on the display.


I made several attempts both without delays and with delays of varying degrees.

Unfortunately I always get black screen in Marlin mode 12864.


I also tried the Marlin mode LCD2004. I inserted the following code into the Marlin firmware.


And I selected Marlin Mode Type 20x4 on the display.

But nonsense characters appear on the display and move when I rotate the encoder.

These are my configuration files

Configuration.h Configuration_adv.h
Can someone help me?
