We are developing a user interface by using STM32H743 + SDRAM + LTDC + DMA2D and connecting to LCD through an FPC cable, which is only 30 CM long. It works fine.
But there is one problem, in some of our products, the LCD can be placed at a position that is 2 meters away from the control board. So I brought a 2-meter-long FPC cable, and the test result was quite bad. Images on LCD became quite unstable and the touch function totally broke down...
Is there any solution for this problem?
