Okay, I'll bite.
What do I need to include to use USB_Class_CDC_Init()?
I created a new, bare metal, FRDM-K64F project. I used KSDK 1.2 and PEx. I added an fsl_usb_descriptors component, edited it, and Generated Processor Expert Files.
Now I want to call USB_Class_CDC_Init(). The only header file I can find that references it is usb_class_cdc.h, but it declares the function as extern.
extern usb_status USB_Class_CDC_Init(...);
I can see that usb_cdc.c actually defines the function; but, usb_cdc.h does not expose it.
Since I've already built the demo project, I have a usb_cdc.o available. How do I tell my project to use it?
