Hi All,

My hardware is custom STM32F429 board with 7'' TFT.

Display has no U/D or R/L display mode select pin.

I don't see datasheet LTDC registers to configure scanning order.

Actually i do it manually in software, perhaps using DMA2D will be quicker but still is to slowly

There is some idea to setup it ?

Hi,

You can have a look to the LTDC examples under STM32CubeF4 package, it maybe helpful for you:

STM32Cube_FW_F4_V1.13.0\Projects\STM324x9I_EVAL\Examples\LTDC\LTDC_Display_2Layers

This example can be a starting point to learn about programming the display as it describes how to configure the LTDC peripheral to display two Layers at the same time.

You can also, refer to the

http://www.st.com/content/ccc/resource/technical/document/reference_manual/3d/6d/5a/66/b4/99/40/d4/DM00031020.pdf/files/DM00031020.pdf/jcr:content/translations/en.DM00031020.pdf

, section 16 LCD-TFT controller (LTDC)
