##Build Firmware & Program
|
||||||
|
You can choose some combination of hardware and USB protocol stack([LUFA], [PJRC]).
|
||||||
|
|
||||||
|
### Install Tools
|
||||||
|
See [this document](../../doc/build.md).
|
||||||
|
|
||||||
|
### TMK Alt Controller Board
|
||||||
|
$ make -f Makefile.tmk
|
||||||
|
|
||||||
|
This programs the controller with [dfu-programmer] if the tool is intalled and configured properly.
|
||||||
|
|
||||||
|
$ make -f Makefile.tmk dfu
|
||||||
|
|
||||||
|
Push reset button and program with [FLIP]. The tool should be intalled and configured properly.
|
||||||
|
|
||||||
|
$ make -f Makefile.tmk flip
|
||||||
|
|
||||||
|
Or you can also program with FLIP GUI.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
|
||||||
##Build Firmware
|
### PJRC Teensy++
|
||||||
You can choose some combination of MCU and USB protocol stack.
|
Build with [LUFA] USB stack:
|
||||||
|
|
||||||
### Teensy++(AVR USB family) with [LUFA]
|
$ make -f Makefile.lufa
|
||||||
0. Edit **matrix.c** to use your pin configuration. See doc/HHKB.txt for detail.
|
|
||||||
|
|
||||||
1. Edit **keymap.c** to use your favoirte keymap.
|
or with [PJRC] USB stack:
|
||||||
|
|
||||||
2. Edit **Makefile** if you want to use other `MCU` than Teensy++ 2.0.
|
$ make -f Makefile.pjrc
|
||||||
|
|
||||||
3. Build firmware binary file:
|
Push reset button and program with [Teensy Loader(command line)]. The tool should be intalled and configured properly.
|
||||||
`$ make -f Makefile.lufa`
|
|
||||||
|
|
||||||
4. Program MCU with PJRC [Teensy Loader] tool. If you install command line version of the loader just run:
|
$ make -f Makefile.lufa teensy
|
||||||
`$ make -f Makefile.lufa teensy`
|
$ make -f Makefile.pjrc teensy
|
||||||
|
|
||||||
|
Or you can also program with [Teensy Loader(GUI)].

###AVR Mega with [V-USB]
|
###AVR Mega with [V-USB]
|
||||||
Follow below if you want to use AVR with V-USB as .
|
Build:
|
||||||
|
$ make -f Makefile.vusb
|
||||||
|
|
||||||
0. Edit **matrix.c** to use your pin configuration. See doc/HHKB.txt for detail.
|
Program [USBaspLoader] on MCU with AVR programmer like [AVRISPmkII] and tool like [avrdude].
|
||||||
|
|
||||||
1. Edit **keymap.c** to use your favoirte keymap.
|
You can programs with [avrdude] once you have programmed [USBaspLoader] on MCU.
|
||||||
|
$ make -f Makefile.vusb program
|
||||||
|
|
||||||
2. Edit **usbconfig.h** to configure V-USB options.
|
[AVRISPmkII]: http://www.atmel.com/tools/AVRISPMKII.aspx
|
||||||
|
[avrdude]: http://www.nongnu.org/avrdude/
|
||||||
3. Edit **Makefile.vusb** to define `MCU` and `F_CPU`.
|
|
||||||
|
|
||||||
4. Build firmware binary file:
|
|
||||||
`$ make -f Makefile.vusb`
|
|
||||||
|
|
||||||
5. Program MCU with AVR programmer like AVRISPmkII. If you already have [USBaspLoader] on MCU just run:
|
|
||||||
`$ make -f Makefile.vusb program`

##Hardware
|
##Hardware
|
||||||
|
You have some options for hardware. Development boards with USB AVR family(ATMega32U4, AT90USB1286) like Teensy will work while MegaAVR with V-USB library is also cheapear option for DIY.
|
||||||
|
|
||||||
###Teensy++ installation

###1. TMK Alt Controller Board
|
