Build & Program
Install Tools
First, you need tools to build firmware and program your controller. I assume you are on Windows here.
-
Install WinAVR. This is old but works well for this purpose.
WinAVR
is a tool set to build firmware including C compiler(gcc) and make commands. You can use CrossPack instead if you are on Mac. -
Install Atmel FLIP.
FLIP
is a tool to program(load) firmware into AVR controller(ATMega32u4) via DFU bootloader. ATMega32u4 has DFU bootloader by factory default. You can use dfu-programmer instead if you are on Mac. -
Install driver for DFU bootloader. At first time you start DFU bootloader on Chip 'Found New Hardware Wizard' will come up on Windows. If you install device driver properly you can find chip name like 'ATmega32U4' under 'LibUSB-Win32 Devices' tree on 'Device Manager'. If not you shall need to update its driver on 'Device Manager'. You will find the driver in
FLIP
install directory like: C:\Program Files (x86)\Atmel\Flip 3.4.5\usb. If you usedfu-programmer
install its driver.
If you use PJRC Teensy you don't need step 2 and 3, just get Teensy loader.
Download source
You can find firmware source at github: https://github.com/tmk/tmk_keyboard
If you are familiar with Git
tools you are recommended to use it.
If not you can download zip archive from: https://github.com/tmk/tmk_keyboard/archive/master.zip
Build firmware
-
Open terminal window to get access to commands. You can use
cmd
in Windows orTerminal.app
on Mac OSX. In Windows pressWindows
key andR
then entercmd
in Run command dialog showing up. -
Move to project directory in the firmware source.
cd tmk_keyboard/{keyboard or converter}/
-
Build firmware using GNU
make
command. You'll see _.hex file in that directory unless something unexpected occurs in build process.mkae -f Makefile. clean make -f Makefile.
Program Controller
Sock AVR USB chip including ATmega32U4 has DFU bootloader by factory default, you can use DFU tools for this purpose. FLIP
is a DFU tool on Windows offered by Atmel. Open source command line DFU tool dfu-programmer
also supports AVR chips, which run on Linux, Mac OSX and even Windows. If you have a PJRC Teensy you should use Teensy Loader
.
DFU bootloader
To program AVR chip with DFU bootloader use FLIP
or dfu-programmer
.
If you have a proper program command in Makefile
just type this.
FLIP
has two version of tool, GUI app and command line program. If you want GUI see tutorial section below.
To use command line tool run this command. Note that you need to set PATH variable properly.
$ make -f Makefile.<variant> flip
To program with dfu-programmer
run:
$ make -f Makefile.<variant> dfu
Teensy
If you have PJRC Teensy see instruction of Teensy Loader
at: http://www.pjrc.com/teensy/loader.html
Or use this command if you have command line version of Teensy Loader installed.
$ make -f Makefile.<variant> teensy
Other programmer
You may want to use other you favorite programmer like avrdude
with AVRISPmkII, Aruduino or USBasp. In that case you can still use make target program
for build with configuring PROGRAM_CMD in Makefile.
$ make -f Makefile.<variant> program
FLIP GUI tutorial
-
On menu bar click Device -> Select, then.
ATmega32u4
. -
On menu bar click Settings -> Communication -> USB, then click 'Open' button on 'USB Port Connection' dialog. At this point you'll see greyouted widgets on the app get colored and ready.
-
On menu bar click File -> Load HEX File, then select your firmware hex file on File Selector dialog.
-
On 'Operations Flow' panel click 'Run' button to load the firmware binary to the chip. Note that you should keep 'Erase', 'Blank Check', 'Program' and 'Verify' check boxes selected.
-
Re-plug USB cord or click 'Start Application' button to restart your controller. Done.

Makefile Options
1. MCU and Frequency.

3. Programmer
Optional. 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 chip with DFU bootloader
PROGRAM_CMD = dfu-programmer $(MCU) flash $(TARGET).hex
# avrdude with other methods
PROGRAM_CMD = avrdude -p $(MCU) -c avrispmkII -P USB -U flash:w:$(TARGET).hex

Debuging
Use PJRC's hid_listen
to see debug messages. You can use the tool for debug even if firmware use LUFA stack.
You will see output from firmware like this.

Magic
key bind may be LShift
+ RShift
in many project, but Power
key on ADB converter. Magic
keybind can be vary on each project, check config.h
in project directory.
Following commands can be also executed with Magic
