Hello,
I am working with an STM32F769I-DISCO board and trying to implement functionality that allows switching between USB Host and Device modes via a button press. I have configured the board for OTG/Dual Role in STM32CubeMX, but I did not enable the Middleware for USB Host or USB Device, so I need to manage the switching at the register level and using HAL APIs.
I would appreciate any advice or code examples for properly managing this switch:
-
Initialization: How should I correctly initialize the USB peripheral to support both modes (Host and Device)?
-
Mode Switching: What are the recommended steps to deactivate one mode and activate the other without causing conflicts or stability issues?
-
Specific APIs and Registers: Are there specific HAL APIs to use, or do I need to manipulate the registers directly? If so, which are most relevant for this purpose?
I've attempted to implement a basic switch using HAL_PCD_Stop() and HAL_HCD_Start(), but I'm not sure if this is the best approach. Also, I am open to suggestions to ensure a smooth and stable transition between modes.
Any help or direction would be greatly appreciated!
Thank you in advance,
