Hi,
I want to use usb cdc vcom in a new project, for example the hello_world project. I add the usb package in the Manage SDK components window.
Then I copy the source file from usb cdc vcom example and build it.
I get the error msg:
"undefined reference to `USB_DeviceCdcAcmRecv"
"undefined reference to `USB_DeviceCdcAcmSend"
I check the includ path it is the same with the vcom demo. I have put the project file in the attachment.
I wonder what is the correct way to add usb function, any doc or guide?
Thanks.
