X-NUCLEO-GFX01M2 on WB55RG only gives blank LCD

[DavePfz]

I am trying to bring up the GFX01M2 on a WB55RG board. Following any of the Custom, FlashLoader, or HelloWorld applications (from the X-CUBE-DISPLAY_3-0-0 download) using STM32CubeIDE merely results in a blank LCD.

I feel I'm missing something simple, but just can't find it. In each case I have compiled and loaded the files as per the ReadMe instructions.

Any pointers appreciated...

Just to be clear, that is a Nucleo-WB55RG board - yes?

[DavePfz]

Yes. The specific combination (I tend to be lazy!) is NUCLEO-WB55RG and X-NUCLEO-GFX01M02.

In examining the code, I think I see the problem. The specific code at:

C:\ST\X-CUBE-DISPLAY_3-0-0\Projects\NUCLEO-WB55RG\Applications

calls out the ST7789V controller.

The datasheet for the Displaytech DT022CTFT says that it uses the ILI9341 controller!

My first thought was to simply substitute the corresponding files, but I find it's not that simple. Can someone point me to code that implements the ILI9341 on the NUCLEO-WB55RG board?

Thanks.

The combination is supported in TouchGFX version 4.25.0 (and presumably later)
