Hi everybody!

I have a project which uses STM32F769 Discover board.

In my project, I want to record voice, save that voice data and then play that data after I press user button.

I also referred to demonstration example (on STM32Cube_FW_F7_V1.8.0) and found that, in that demonstration example, the recorded data is saved on USB.

Could you please tell a suggestion to save that voice data without using USB if my voice data is less than 1MB.

Thank you for your attention.

Short term, the SDRAM

You could then write into QuadSPI FLASH, or to a MicroSD card

Could you tell me more detail about saving on SDRAM or QSPI memory, I try to save voice data to QSPI at address of 0x3F60000 but not successful.

The SDRAM when configured presents at 0xC0000000, and can be read and written like internal RAM, only slower.

The QSPI memory is going to require more involvement to write
