Interfacing a RGB Display with STM32F407

[GK28]

Hello,

I have a STM32F407 microcontroller with a FSMC interface, which I would like to use to drive this display: NHD-5.0-800480AF-ASXP. The display has a RGB interface.

Should I get a RGB board? Or can I drive it directly with the microcontroller?

Is that a time intensive solution?

Thanks to everyone who replies, I appreciate it very much.

Hello @GK28 and welcome to the community,

The LCD that needs to be driven by STM32F407 over FSMC interface needs also to have 8080 parallel interface:

If the LCD has RGB interface R, G, B lines, you cannot drive the LCD with STM32F407 but you can with STM32F429 over LTDC:

From the LCD datasheet:

Hope that answers your question.
