These excellent articles make the USBX worth a go for more complicated tasks (I wish composite devices were supported in CUBE IDE),
- How to implement the USB device composite class in STM32 using the Azure package
- How to implement the USB Device CDC (VCOM) in STM32 using the Azure USBX package
When creating a composite device, I see that USB_OTG_HS was used rather than the USB_OTG_FS. I know that the HS can use the internal FS PHY STM32 (so it is FS under-the-hood). However, it also changes the pins! My particular application is highly constrained, and I cannot change the pins, so I need to use USB_OTG_FS.
Can I use USB_OTG_FS along with Azure USBX to create a composite device, or does it require USB_OTG_HS?
