##Build Firmware & Program | |||||
You can choose some combination of hardware and USB protocol stack([LUFA], [PJRC]). | |||||
### Install Tools | |||||
See [this document](../../doc/build.md). | |||||
##Build Firmware | |||||
You can choose some combination of MCU and USB protocol stack. | |||||
### Teensy++(AVR USB family) with [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. | |||||
2. Edit **Makefile** if you want to use other `MCU` than Teensy++ 2.0. | |||||
### TMK Alt Controller Board | |||||
$ make -f Makefile.tmk | |||||
3. Build firmware binary file: | |||||
`$ make -f Makefile.lufa` | |||||
This programs the controller with [dfu-programmer] if the tool is intalled and configured properly. | |||||
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.tmk dfu | |||||
[LUFA]: http://www.fourwalledcubicle.com/LUFA.php | |||||
[Teensy Loader]: http://www.pjrc.com/teensy/loader.html | |||||
Push reset button and program with [FLIP]. The tool should be intalled and configured properly. | |||||
$ make -f Makefile.tmk flip | |||||
###AVR Mega with [V-USB] | |||||
Follow below if you want to use AVR with V-USB as . | |||||
Or you can also program with FLIP GUI. | |||||
0. Edit **matrix.c** to use your pin configuration. See doc/HHKB.txt for detail. | |||||
[dfu-programmer]: http://dfu-programmer.sourceforge.net/ | |||||
[FLIP]: http://www.atmel.com/tools/FLIP.aspx | |||||
1. Edit **keymap.c** to use your favoirte keymap. | |||||
2. Edit **usbconfig.h** to configure V-USB options. | |||||
### PJRC Teensy++ | |||||
Build with [LUFA] USB stack: | |||||
3. Edit **Makefile.vusb** to define `MCU` and `F_CPU`. | |||||
$ make -f Makefile.lufa | |||||
4. Build firmware binary file: | |||||
`$ make -f Makefile.vusb` | |||||
or with [PJRC] USB stack: | |||||
5. Program MCU with AVR programmer like AVRISPmkII. If you already have [USBaspLoader] on MCU just run: | |||||
`$ make -f Makefile.vusb program` | |||||
$ make -f Makefile.pjrc | |||||
[V-USB]: http://www.obdev.at/products/vusb/index.html | |||||
[USBaspLoader]: http://www.obdev.at/products/vusb/usbasploader.html | |||||
Push reset button and program with [Teensy Loader(command line)]. The tool should be intalled and configured properly. | |||||
$ make -f Makefile.lufa teensy | |||||
$ make -f Makefile.pjrc teensy | |||||
###How to Customize Keymap | |||||
Later... | |||||
See **keymap.c**. | |||||
Or you can also program with [Teensy Loader(GUI)]. | |||||
[LUFA]: http://www.fourwalledcubicle.com/LUFA.php | |||||
[PJRC]: http://www.pjrc.com/teensy/usb_keyboard.html | |||||

[Teensy Loader(GUI)]: http://www.pjrc.com/teensy/loader.html | |||||
##Hardware | |||||
###Teensy++ installation | |||||
Angled USB mini B adapter is used to install Teensy++ laterally. | |||||
###AVR Mega with [V-USB] | |||||
Build: | |||||
$ make -f Makefile.vusb | |||||
![Image of Teensy install](hhkb/doc/HHKB_img/teensy_install.jpg) | |||||
Program [USBaspLoader] on MCU with AVR programmer like [AVRISPmkII] and tool like [avrdude]. | |||||
Bread baord wires are used to connect Teensy++. | |||||
You can programs with [avrdude] once you have programmed [USBaspLoader] on MCU. | |||||
$ make -f Makefile.vusb program | |||||
