Hi, I want to integrate an 24-bit parallel LCD(change from 640×480 to 800×480) with STM32H743I-EVAL board. But I am a beginner for this field. So I followed this video > https://www.youtube.com/watch?v=yiHjOH7zJP0.
What I have done is below:
- Created the folder using the sample template (STM32H743I EVAL) by TouchGFX Designer(V4.19.0)
- Open the STM32CubeMX file (V6.5.0)
- Changed PLL3 of Clock Configuartion from 32 to 24 to set 33.3MHz
- Changed LTDC values related to custom LCD
- The rest of the work was done exactly as shown in the video
However, the results are not good.
I'd really appreciate it if you could let me know what I'm doing wrong.
Please refer to the images below.
Result is:

Maybe two problems
- LCD mode other as need RGB
- FMC memory config fail
Start testing without TouchGFX only setup LTDC

I am not using Touchgfx, instead modified the LTDC part of the sample file a little and upload it, but it worked well.
