demo for EFM32 usb library usage

[Banxian]

Hello, I have a EFM32HG309 chip which I made for usb to CDC(acm) usage.
I found visualgdb have a tutor which introduced it have EFM32 usb lib.

https://visualgdb.com/tutorials/arm/efm32/

so, how do I create a usb cdc device sample from VisualGDB project wizard?
I can’t find other EFM32 guides in sysprogs website.
If I start from STM32 chip, I found a usb communication device in sample selection step,
but with EFM32 (HappyGecko with usb fs), only LEDBlink appeared.

should I need port it myself from silabs an0065?

Hi,

Sorry, we do not have any USB examples for the EFM32 chips. Please consider asking on StackOverflow or EFM32 forums to get further pointers.
