Integration of MIPI DSI Display with TouchGFX

[SSG]

Hi,

We built a custom board using STM32L4R9AI MCU. The board contains a display with following specification

• Display driver: RM69330
• Connection Interface: MIPI DSI
• Display Size: 454x454

We can initialize the display properly because the all pixel can be turned on.

When we tried to integrate the display with TouchGFX 4.23.2, we have faced some issues. I have attached here the pictures of what we want to display and what we are getting. Could you please help me by providing some insights why is this happening? I am sorry for the bad resolution of pictures.

1) Screen we designed in TouchGFX

2) Screen we got from display

Hello @SSG,

Besides being able to turn on all the pixels, can you display simple data (like a static color) before combining it with a TouchGFX project?

If you are capable of displaying a simple color, then I suggest drawing inspiration from the TouchGFX Board Setup (TBS) available for STM32F769I Discovery Kit since it is also using MIPI DSI display.
