I am evaluating different dual-core ARM Cortex-A7 MPUs for their graphical features; one of my requirements is that I need to support a 1280x1024 TFT LCD at 50-60fps using 16 or 24-bit parallel RGB interface.The evaluation kits offer small LCDs below...

Gregoire,Any news on this package?Also, besides the setup that you've detailed above, should we expect any changes to the RFAL library or the ST25R3911B support files?Thank you!

@PatrickF thank you so much for your insight! That makes sense. It seems that with a good hardware setup and lower porch/sync values (and an HSE oscillator), higher resolutions are definitely possible. Also, I did not know this limitations document ...

Ah, that makes a lot of sense. So I am assuming that since I am not serializing my RGB data via DSI, I don't have to worry about this at all?Suggestion to ST: if this is the case, you might want to move that spec out of your "general LCD TFT spec" se...

I appreciate the effort! Thank you.

Thank you for a quick reply.While that thread and app note are applicable to working with LTDC itself, there are major differences between ST's MCUs and MPU lines:The older thread applies to the high-end MCU lines. The new MPU line seems to be quite ...
