LCD 240*128 on RA6963 connect to ESP32-C6

[FlintBMF]

I’m a complete beginner with Arduino/ESP32 and just starting to learn.
I’m working on a weight measurement system using HX711 and an ESP32-C6-DevKitC-1.

At first, I tested my setup with:

• Adafruit Monochrome 1.12" 128x128 OLED via I2C
• LCD 2004 (20x4) with PCF8574A I2C adapter

Both worked fine using the I2C interface.

Now, I’m trying to connect a bigger display: WG240128B-TFH-TZ with an RA6963 chip. It has 20 pins. I found a pinout for a similar display.

I tried following this tutorial: Arduino With T6963c 240x128 Graphic LCD but it didn’t work.

Could someone guide me how to connect it using the U8glib or U8g2 library? Or maybe suggest another way to get it working with ESP32-C6?

Thanks in advance!

Sorry, almost forgot — here is the wiring diagram I made:

Please let me know if something looks wrong or if I should wire it differently.

Just found the documentation for my exact display model (WG240128B-TFH-TZ):
