Arduino for STM32

I would like to try USB Host with STM32F407VG (DiyMore board)

I've been trying to understand why the repository is incomplete, despite having the libraries already.

STM32CubeIDE appears to work with similar libraries, and is already functional. I liked the speed of writing a USB stick.

Unfortunately, something seems to be missing from the repository, so support is not provided officially:

For the USB Host, there is no dedicated implementation but the STM32_USB_Host_Library is already included and already in the USB request list: #687

In case anyone else wants to try to make it work.

STM32F407VG (DiyMore) USB Port FS (CN1 or PA11: DM, PA12: DP; PC9: Drive_VBUS)

Functional Example; STM32CubeIDE (V1.3.0; FW_F4 V1.25.0)
https://github.com/stm32duino/Arduino_C ... SC_CPP.zip

Arduino example; Not Functional, but compiles without errors, It must be missing to call some routine.

Sketch uses 15900 bytes (1%) of program storage space. Maximum is 1048576 bytes.

It is not incomplete, the USB Host library is provided but currently not used that's all.
As I answered you on GitHub, while no dedicated development done for this, there is no reason to have it to the include path.

As an example how to integrate it, look at how the USB device was integrated this should be the same way for the host.

Are you able to access USB disk via arduino IDE. I read you post and understood there is some gap in the linkage.
Actually i am trying to read the USB thumb drive via USB port but unable to do so in arduinoIDE.
I am checking your STM32CUBE code you posted in github for reference.

Hi,
were you able to use the USB-OTG for thumbdrive reading/writing?
I have a BlackPill STM32F401 and it would be great if I could its capability...

Hi,

For STM32CubeIDE see:

("Training materials (slides, hands-on projects) can be downloaded" Guys: download the material to follow up better, link in the description!!!)
