MT-DB-U2
Manual
Old Demo Program
The old demo program makes use the use of the MTDBU2 as a CDC device (virtual COM
port). This is one of the most common ways to connect to a PC over USB. It uses Dean Camera's
opensource LUFA USB library available at
http://www.fourwalledcubicle.com/
. The LUFA download
includes many examples that can be easily compiled for the ATmega32U2.
See the CDC Bootloader section for details on installing the CDC Serial driver. The old demo
requires an ANSI terminal to allow drawing of the menu system. If you see garbage on the terminal
screen, click on the configuration icon and change the emulation to ANSI (or ANSIW). After
connecting, a message that reads “Press any Key” is printed periodically. If you do not see this
message, just press any key to continue.
