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!

[Nimit Vachhani]

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).

Perhaps should be looking at the STM32F105/107 devices, or one of the newer L4 devices that isn't 12-13 years old.

Indeed - back then, USB Host in a microcontroller was rare ...

[Nimit Vachhani]

Will it be compatible with STM32F103 devices ?

[Nimit Vachhani]

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...

[Andrew Neil]

Will what be compatible?

And in what way, "compatible" ?

We've established that the STM32F103RE  has no USB Host capability - so there is nothing there to be compatible with!
