STM32H743 QSPI function

[ggyy426]

Hi all

I want to know where should I use QSPI function?

TouchGFX has initialized QSPI but it doesn't call

For my demo project my STM32H743eval LCD only on

But image not showing.

How to solve this?

Hi,

I think we're discussing something similar in another thread. Are you saying that neither QSPI_Init() or Display_Init() are being called?

Yes it only call

QSPI_Init()

Display_Init()

So LCD only light but no data read from QSPI.

So I wanto know Where should I call BSP_QSPI read() function?

Something you can do is check your STM32xxDMA.cpp class and break in fillRect() - This is the DMA occupying its queue with blitops if you have images that can be moved from qspi to framebuffer. You should find that these blitops have a source pointer - And you can check against your map file to verify that it's trying to transfer your image.

Hi Martin

You mean STM32H7DMA.cpp

But I don't find fillRect() function

So I need to include which header file to use fillRect() function?

You mean I can use DMA to draw the photo in my QSPI?
