I'm working on a project where I need to output some debug strings on a CDC virtual COM.
#define BOARD_DEBUG_UART_TYPE DEBUG_CONSOLE_DEVICE_TYPE_USBCDC
This way some code is enabled to be compiled; it calls the following functions:
These functions aren't defined anywhere in the project code, I've shearched in all the SDK files (version 2.3), but I'm not been able to find them.
Where can I find them? Do I need to write them my own way?
