I am new to ST and need support. I want to use USB in my project but I am unable to find a example to use usb as a storing device. Please any one share complete example or any tutorial.

Thank you in advance

Hi

khan.daynial

‌,

Please try to provideadditional information (about your device,toolchain that would beuse) that might help to get more response.

If you are CUBE user, your can find a working MSC application with different tool chains (EWARM,MDK-ARM,SW4STM32)under the STM32 cube firmware relevent for your device.

(For example, at this pathwithin

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-embedded-software/stm32cubef4.html

:

STM32Cube_FW_F4_V1.0\Projects\STM324xG_EVAL\Applications\USB_Device\MSC_Standalone)

The reference Manual and datasheet related to your device will be your support for more details.

Hope this helps you.

Thanks
