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

[Salvatore Giachinta]

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 REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
#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.

#define REPRAP_DISCOUNT_SMART_CONTROLLER

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?

No, but i have the same Problem with the SKR 1.4 Turbo and the same display maybe it is a Problem with the PCB design of the TFT 24 or a Hardware issue.

I just had this same issue. After combing through the configuration.h for Marlin I found this line needed to be changed to WESTERN. By default it is JAPANESE. Also, you want it set to 128x64.

 

#define DISPLAY_CHARSET_HD44780 WESTERN
