STM32F103RE USB HOST FOR KEY DISK

[Nimit Vachhani]

Greetings Everybody,

I am confused whether i cam make STM32F103RE to work as usb host for mass storage ? In CUBE MX it says mass storage class but does it mean i can connect my USB disk to it and transfer data to it ?

I know STM32F207ZG has the support of USB OTG and it is working fine as i am logging data to the connected usb disk... Can i have this feature in STM32F103RE ?

Any advice would be of great help.

Thanks.

I'm thinking not, but check if there are host examples in the CubeF1 trees for the EVAL boards.​

Like @Community member​ , I think not - but what does the datasheet tell you? That will be the definitive answer!

Well it does not have otg host support... Nothing regarding this is mentioned in data sheet. Thanks for the info...

The datasheet tells you that it has USB Device:

So that's not Host (nor OTG).

Checked... It will not work as usb host device. I will work as usb device when connected with the compatible operating system. It uses bulk transfer method...
