Installation

Driver Installation

Windows

Prior to core version 1.6.9mt1, sketches compiled with both CDC and HID USB code by default, thus
requiring a CDC driver for the bootloader and a CDCHID driver for sketches. Now that PluggableUSB

is supported, sketches compile with only CDC code by default. Thus, only one driver is needed. Since
HID and MIDI are currently supported (and MSD potentially in the future), driver installation will be

required for each different combination of USB devices. There are currently four USB composite
device combinations that include CDC as well as a CDC only device. Each supported combination has

a unique USB VID:PID pair, and these are listed in the .inf file. Once the first device is installed (the
CDC only device), future installations

might

be automatic, otherwise, you may direct the installer to the

same .inf file. The drivers are signed and support both 32 and 64 bit versions of Windows XP(SP3),
Vista, 7, 8, and 10.

1.

If you do not already have the CDC bootloader installed, see below.

2.

Download

https://www.mattairtech.com/software/MattairTech_CDC_Driver_Signed.zip

and

unzip into any folder.

3.

Plug in the board with the jumper installed. The LED should light.

4.

Windows will detect the board. Point the installer to the folder from above to install the
bootloader driver.

5.

If you don't intend on using Arduino, you can skip the rest of this list. See Using AVRDUDE
Standalone below.

6.

If you do not already have the test firmware installed, see Using AVRDUDE Standalone below.

7.

Press the reset button to run the test firmware (blink sketch).

8.

Windows will detect the board. Point the installer to the above folder to install the sketch driver
(if needed).
