STM32F746 Custom With TFT 7inch

[HAnh]

I had make STM32F746 board with TFT 7inch base on STM32F746-Disco for my project.

i tried to program sample file "application-std" from STM. it show 1/2 screen (272x480), that mean my PCB run normal.

But my screen is 480x800 (7inch). how to i config STM32F746 with TFT 7inch using CubeIDE.

I tried to change in example code (X axis = 272 to 480, Y axis 480 to 800), but it not run.

Can anyone help me in this case?

Thanks all of yo for your support

Hello,

Can you explain what you did exactly? Which files you changed? And then if you have the datasheet of the display, are you sure you have the correct timing (pixel clock, vsync, hsync) configured in the LTDC peripheral?

Hi AME MCU Support Center BB.

Thanks for your reply.

I have made it runned last night. But it seem run not smoothly due to sweep frequency.

This is code i have modify:

This is TFT information

In other problem, my touch screen can't run, i'm worndering we need modify anything in "STM32Touchcontroller.ccp" if we change TFT 4.3inch to TFT 7.0inch (using same Touch IC).

Can you let me know and solve my problem

Thanks and best Regards.
