Build & Program

Build firmware

To compile you need AVR GCC, AVR Libc and GNU make. You can use WinAVR on Windows and CrossPack on Mac.

$ cd <project>
$ make

The firmware will be compiled as a file tmk_.hex.

Program Controller

If you have proper program command in Makefile just type this.

$ make program

As for Teensy you can use PJRC's loader to program hex file. http://www.pjrc.com/teensy/loader.html

Build Options

Makefile

1. MCU and Frequency.

MCU = atmega32u4       # Teensy 2.0
#MCU = at90usb1286      # Teensy++ 2.0
F_CPU = 16000000

2. Features

Note that comment out to disable them. MOUSEKEY_ENABLE = yes # Mouse keys PS2_MOUSE_ENABLE = yes # PS/2 mouse(TrackPoint) support EXTRAKEY_ENABLE = yes # Enhanced feature for Windows(Audio control and System control) NKRO_ENABLE = yes # USB Nkey Rollover

3. Programmer

Set proper command for your controller, bootloader and programmer. # for PJRC Teensy PROGRAM_CMD = teensy_loader_cli -mmcu=(MCU) -w -v (TARGET).hex

# for Atmel AT90USBKEY
PROGRAM_CMD = dfu-programmer $(MCU) flash $(TARGET).hex

# avrdude
PROGRAM_CMD = avrdude -p $(MCU) -c avrispmkII -P USB -U flash:w:$(TARGET).hex
PROGRAM_CMD = avrdude -p $(MCU) -c usbasp -U flash:w:$(TARGET).hex
PROGRAM_CMD = avrdude -p $(MCU) -c arduino -P COM1 -b 57600 -U flash:w:$(TARGET).hex

config.h

1. USB vendor/product ID and device description

#define VENDOR_ID       0xFEED
#define PRODUCT_ID      0xBEEF
/* device description */
#define MANUFACTURER    t.m.k.
#define PRODUCT         Macway mod
#define DESCRIPTION     t.m.k. keyboard firmware for Macway mod

2. Keyboard matrix configuration

#define MATRIX_ROWS 8
#define MATRIX_COLS 8
#define MATRIX_HAS_GHOST

3. Mouse keys configuration

4. PS/2 mouse configuration

Keymap

Build your own firmware

Debuging

Use PJRC's hid_listen to see debug messages and press <COMMAND> + H to debug menu. See config.h for definition of <COMMAND> key combination.
