STM32 development board that uses the 24 bit RGB interface

asked Dec 5, 2019 in Platform Packages by ezed413
I need to connect a 3.5-in Newhaven 320 x 240 TFT that uses the 24 bit interface to a STM32 Discovery board. What would be my best choice? At the moment, I am using the STM32F429 discovery board with the onboard display. I would like to hook up the display we want to use to the discovery board for development.

Hello ezed413,


the STM32F429 Discovery has already mounted a parallel display. That's the same connection interface as your new display needs.

In general it will be nessasary to adapt the Build Environment to your new display by adapting the display configuration. For that you’ll find the 'ew_bsp_display.c/.h files' in the ‘TragetSpecififc' folder, which you can find in the STM32F429 Discovery Build Environment. In the Getting Started Article for the STM32F429 Discovery you’ll find a chapter ‘Custom specific hardware’ that describes how to reconfigure the LTDC display controller.

Please also do care about the framebuffer and screen size configuration in ‘Application/Source/ewmain.c’.

Hopefully this will help. If you have further questions, feel free to ask.


Best regards,

Thanks Tim,

Yeah, we are ordering the STM32F746G-DISCO board. It will just make it a whole lot easier. This board looks like it has a 40 pin FFC connector which I can adapt to a 54 pin FFC with breakout boards. Again, thanks for this great information!
