STM32F469I Discovery 800*480 LCD display

[User.63]

Hi~

I have a problem to configure LCD display of STM32F469 discovery.

I'm using   STM32CubeMX 5.1.0 + TouchGFX 4.10.0 + IAR Embedded Workbench 8.32.1.

My project was created by STM32CubeMX 5.1.0 - STM32F469I-DISCO board.

I changed display mode from 400*480 portrait to 800*480 landscape in accordance with guideline.

Picture is well displayed on 800*480 LCD.

But leftside picture 400*480 is copyed on right side.

In source code STM32F4HAL_DSI.cpp,

when update Region, LCD_SetUpdateRegionLeft() and LCD_SetUpdateRegionRight()

is same result.

What is fuction name whitch I check?

Can you please try with the latest verison of CubeMX? 5.2.0.

STM32F469 / F769 project generation has had issues in the past and may still.

I tried with CubeMX 5.2.0 and STM32Cube FW 1.24.1.

and changed CubeMX setting according to following link,

https://touchgfx.zendesk.com/hc/en-us/articles/360020208091-Configuring-STM32F769I-DISCO

Result is same.

I tihnk this is very simple cause. (may be not)

But I can not find function whitch i would fix.

Please let me know why full screen is not displayed (even academically).

@병준 전​,

What do you mean by "academically" ? The guide was made to compensate for errors in 5.1.0 project generation. What happened if you did not make the modifications from the document?

I coluld not find it.

Sincerely thank for your reply.

Thank you for relpy.

I had a mistake.

==> NVIC_DisableIRQ(LTDC_ER_IRQn);//NVIC_DisableIRQ(LTDC_ER_IRQn);

I thought // is just remark for example link.

But // was required for LCD.

Finally it operated well.

Thanks ST community.
