STM32H743 QSPI FLASH

[Charlie CHEN]

Hi all,

Recently, I build a project with TouchGFX for STM32H743,and the total files are more than 2MB,so I have to use external flash memory(W25Q256).

Then, I am trying to use QSPI interface to connect external memory and execute in interrupt method.

But I have no ideal how to build the function,can any one help me or provide source code?

By the way, I have already added the algorithm about W25Q256,and the other initialize was done , backlight was turned on.

Thanks!

Yes, but I have already built a external flash algorithm for it.

And I found all the QSPI function at Community,there is no likely method.

Or do you have any suggest or reference code?

Thanks!
