Midi Fighter Twister - Open Source Firmware

Compilation

The MF Twister Project makes use of the Atmel ASF extensions & LUFA Module.

To compile, the following symbols must be defined

DEBUG
F_USB=48000000UL
F_CPU=32000000UL
USE_LUFA_CONFIG_HEADER
ARCH=ARCH_XMEGA
BOARD=USER_BOARD

The compiler must also link libm

The project also requires a user board configuration header file. If this is missing add the following to conf_board.h

#define CONF_BOARD_ENABLE_USARTD0

How to build using Microchip Studio (Windows-only)

You need Microchip Studio which can be downloaded here

1. Inside Micropchip Studio, open the Midi_Fighter_Twister.atsln solution
2. Select the desired configuration (Debug or Release)
3. Build the solution via Build > Build Solution

The resulting Midi_Fighter_Twister.hex file now can be found in the respective Debug or Release target directory
