STM32F407 SPI+DMA+interrupt with standard library

[Simbaa]

Could you provide a routine for reading and writing external flash using spi+dma+ interrupt in the STM32F407 standard library?

Why don't you try Winbond W25Qxx flash series which works on SPI.

[Simbaa]

Currently, Winbond flash is used. Could you provide an example routine for reading and writing external flash using spi+dma+ interrupt in the STM32F407 standard library?

Can you check if this useful?

Hello @Simbaa 

Please refer to the example SPI_FLASH under "Project\STM32F4xx_StdPeriph_Examples\SPI\SPI_FLASH" on STM32F4xx_DSP_StdPeriph_Lib package.

Could you provide the download link or directly offer the reference program

The project implements the SPI communication in pooling mode you should adapt it to use DMA mode
