These depend a bit on which targets you are trying to build, but the general one:
- cmake (2.8 and higher)
-- Teensy Loader (http://pjrc.com/teensy/loader.html)
AVR Specific (Teensy 1.0/++,2.0/++) (try to use something recent, suggested versions below)
-- avr-gcc (4.8.0)
-- avr-binutils (2.23.2)
-- avr-libc (1.8.0)
+- avr-gcc (~4.8.0)
+- avr-binutils (~2.23.2)
+- avr-libc (~1.8.0)
ARM Specific (Teensy 3.0/3.1) (Sourcery CodeBench Lite for ARM EABI
- git (needed for some compilation info)
- cmake
- gcc-core
+- gcc-g++
+- libusb1.0
+- libusb1.0-devel
-And make sure CMake is *NOT* installed through Cygwin. This is extremely important.
-If this is not possible, you'll have to play with your paths in Cygwin to prioritize the Windows version of CMake.
+Please note, I use cygwin term exclusively for any command line options. Unless mentioned otherwise use it.
+Do NOT use CMD or Powershell.
Also install the Windows version of CMake - http://cmake.org/cmake/resources/software.html
This is in addition to the Cygwin version. This is an easier alternative to installing another C compiler.
Add the following line to your .bashrc, making sure the CMake path is correct:
- alias wincmake="PATH='/cygdrive/c/Program Files (x86)/CMake 2.8'/bin:\"${PATH}\" cmake"
+ echo "alias wincmake=\"PATH='/cygdrive/c/Program Files (x86)/CMake 2.8'/bin:\"${PATH}\" cmake" >> ~/.bashrc
+
+Install the PJRC Virtual Serial Port Driver:
+(http://pjrc.com/teensy/serial_install.exe)
Next, install the compiler(s) you want.
+
---------
| AVR GCC |

You just need the Atmel AVR 8-bit Toolchain. The latest should be fine, as of writing it was 3.4.3.
http://www.atmel.com/tools/atmelavrtoolchainforwindows.aspx
+(Atmel AVR 8-bit Toolchain 3.4.3 - Windows)
Extract the files to a directory, say C:\avr8-gnu-toolchain. Then copy all the folders in that directory to the Cygwin directory.
Mine is C:\cygwin64.

-Use the installer and make sure you add the binaries to your path within the installer.
-
+Look for "Download the EABI Release".
+Enter your info to get the download link.
+Select the most recent download.
+Then download the "IA32 Windows Installer".

-Selecting Architecture

-This is where you choose which architecture you want to build for.
-The options are:
- - Teensy 1.0 (Not tested)
- - Teensy 1.0++ (Not tested)
- - Teensy 2.0
- - Teensy 2.0++
- - Teensy 3.0
- - Teensy 3.1

-NOTE: If you change this option, you will *may* to delete the build directory that is created in the Building sections below.
+Use the installer and make sure you add the binaries to your path within the installer.
Selecting Microcontroller
----------------------
-Even if you selected the "avr" family of microcontroller architectures, you will still need to specify a target microcontroller (or once more ARM microcontrollers are supported).
+This is where you select the chip you want to compile for.
+The build system will automatically select the compiler needed to compile for your chip.

Linux Loading Firmware
----------------------
+First place the keyboard into re-flash mode.
+This can be done either by pressing the re-flash button on the PCB/Teensy.
+Or by entering the Kiibohd Virtual Serial Port and using the 'reload' command.
+
The 'load' script that is created during the build can load the firmware over USB.
-It uses sudo, so make sure you have the priviledges.
+Either run it with sudo, or install the 98-kiibohd.rules to /etc/udev/rules.d
+ and run: udevadm control --reload-rules
+
+To load the newly built firmware:
./load
mkdir build
cd build
wincmake -G "Unix Makefiles" ..
+make

Virtual Serial Port - CLI
----------------------
Rather than use a special program that can interpret Raw HID, this controller exposes a USB Serial CDC endpoint.
This allows for you to use a generic serial terminal to debug/control the keyboard firmware (e.g. Tera Term, minicom, screen)

| Linux |

I generally use screen.
+You will need sudo/root priviledges if you haven't installed the 98-kiibohd.rules file to /etc/udev/rules.d
-sudo screen /dev/ttyACM0
+screen /dev/ttyACM0
+(Might be ACM1, ACM2, etc.)
---------
| Windows |
---------
-TODO Probably COM1, but not exactly sure. Tera Term.
+Make sure the Teensy Virtual Serial Port driver is installed.
+If possible use screen (as part of Cygwin).
+
+screen /dev/ttyS3
+(Might be a different file, ttyS0, ttyACM0, ttyUSB0, etc.)
+
+Gnu screen doesn't seem to echo all the characters (it works though).
+I believe it's a problem with stty, but I don't know how to fix it...
+
+putty works well when using DTR/DSR or RTS/CTS flow control.
