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.
