i have custom stm32h743ii controller for LTDC 24 bit interface with st7272a display. i would like to know HAL API to be used for init and communication with RGB interface. My board does not have the external SDRAM to load the images. Please guide me

You'd setup the LTDC with the appropriate timing to feed the frame data over the RGB bus.​

Look at some of the EVAL board examples. ​

Use CubeMX and fullfill config ...

Get consistent timing settings on the STM32/LTDC and controller side via I2C

Please suggest the sequence of API to be used for LTDC interface with some examples like background color change, Text, circle filling with color and other shapes. The evaluation kit examples does not provide these shape testing. Please share the link here to move further.

I have created a project using cubemx. Please find the attached project source code. i am getting the errors in ltdc interrupt register. i have taken a reference from example project. Even though the DMA2D and LTDC interface thorough errors only. I am stuck to bring it up. please suggest me further.
