STM32H757I-EVAL MB1166-Default-A08 Display Controller

Hi,

I have STM32H757I-EVAL board which has MB1166 Rev A LCD daughter board. I tried to find which display controller is used with this LCD display. 

I had gone through the MB1166 schematics which shows 2 options 

 1. KM-040TMP-02

 2. FRD397B2509

I got confused which one to consider.

And I found different in example code which is OTM8009A.

 

Which display driver used exactly in this board?

 

Thanks,

Satheesh

Both LCD modules of KM-040TMP-02 and FRD397B2509 with same LCD driver IC OTM8009A. so that why you saw OTM8009A in LCD driver code. Based on board history in UM2525, MB1166-Default-A08 BOM is used for STM32H757I-EVAL, based on MB1166-A08 BOM, FRD397B25009 is used on the board.

I have installed STM32CubeIDE v1.14.0 and I have STM32H757I-EVAL board.

I'm unable to find example projects (LCD DSI) for this board in IDE. Instead, I can find LCD DSI example projects for STM32H747I-EVAL board.

Can we run example projects defined for board h747 on h757? 

I cannot upgrade my IDE version as my existing projects restricting.
