Source to READ/WRITE txt files from usb

[OBorr.1]

Hello community!

In the project I'm working on, after the UART communication, I need to configure the USB to be able to read a txt file, creat or write another txt file and to update the frimware.

I'm asking you if there is any source that shows how to do this kind of things. If not, I would like to start reading the txt file in the usb.

I'm using HAL library, FATFS and USB_HOST only with MSC

Thanks for your help!

Hello @OBorr.1​ ,

We provide some examples in our Firmware package. You can refer to one of them.

For example, in the F7 CubeFW you can refer to this application:

• Path: Projects\STM32756G_EVAL\Applications\USB_Device\MSC_Standalone.

BeST Regards,
