Integrating Parallel RGB LCD

[Ofaro.1]

Hi,

At this stage I have tried everything but the LCD is not showing any graphics.

I have created the project in the STMCubeIDE and configured the LTDC & frame buffer parameters as shown in the pics.

I have also added the fmc initialization code in the main loop.

Could anyone kindly direct me in the right direction? Really thanks

One more thing, LCD driver is ST7282. Attached are the details.

I'm wondering do I need to LCD driver for it or I don't need it if I'm using RGB Parallel LTDC configurations.

Start LTDC only , no FMC, no Touchgfx

Layer 0 Framebuffer place into internal RAM .

Check obvious things like pins and clocks. Both at a basic configuration level, and that for example the clocking of the display is occurring. Back-light powered, etc.

Assume no one here is familiar with the specifics of your board, or the STM32 part you're using.

Thanks for your feedback and I apologize for not providing info regarding the controller, currently, I'm testing the LCD on STM32F429I-DISC1 by removing its onboard LCD.

Turned out the LCD which I was using for somehow not displaying any data (only backlight was working as I was providing power externally to it) and when I changed to another LCD it started displaying blue color while in touchGFX it was red. and If I add any text or button it just shows some random colour.

My question is, this garbage colour is it because of a wrongly configured frame buffer or something else?

One more thing I encountered is all of a sudden compiler is giving an error for region flash overflowed, while there's only one screen on it and nothing else.

Really appreciate any feedback.
