Maxim Integrated / Mbed OS FTHR_USB_serial

USB serial demo passes data from virtual serial port to debug serial port

Dependencies:   max32630fthr USBDevice

Fork of FTHR_USB_serial by Greg Steiert

This program receives characters from the virtual USBSerial UART and sends them back out over the virtual USBSerial UART and the DapLink UART. It will also change the status of LED 1 based on the least significant bit of the character received.

The default baud rate for the DapLink UART is 9600, the baud rate does not affect the virtual USBSerial UART.

Windows Driver!
