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
OR
- arm-none-eabi-gcc
- arm-none-eaby-binutils
+(I've actually had some issues with Sourcery CodeBench on Linux, so I often just use these)
----------------------
-Selecting Architecture
+Windows Setup
----------------------
-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
+Compiling on Windows does work, just it's a bunch more work.
-Open up CMakeLists.txt in your favourite text editor.
-You are looking for:
+First make sure Cygwin is installed - http://www.cygwin.com/ - 32bit or 64bit is fine. Make sure the following are installed:
+- make
+- git (needed for some compilation info)
+- cmake
+- gcc-core
+- gcc-g++
+- libusb1.0
+- libusb1.0-devel
- ###
- Compiler Family
- #
+Please note, I use cygwin term exclusively for any command line options. Unless mentioned otherwise use it.
+Do NOT use CMD or Powershell.
- #| Specify the compiler family to use
- #| Currently only supports AVR and ARM
- #| "avr" # Teensy 1.0
- #| "avr" # Teensy 2.0
- #| "avr" # Teensy++ 1.0
- #| "avr" # Teensy++ 2.0
- #| "arm" # Teensy 3.0
- #| "arm" # Teensy 3.1
+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:
+ echo "alias wincmake=\"PATH='/cygdrive/c/Program Files (x86)/CMake 2.8'/bin:\"${PATH}\" cmake" >> ~/.bashrc
- set( COMPILER_FAMILY "avr" )
+Install the PJRC Virtual Serial Port Driver:
+(http://pjrc.com/teensy/serial_install.exe)
+Next, install the compiler(s) you want.
-Just change the COMPILER_FAMILY variable to whatever you are trying to build for.
-NOTE: If you change this option, you will *may* to delete the build directory that is created in the Building sections below.
+ ---------
+| 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)
-----------------------
-Selecting Microcontroller
-----------------------
+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.
+(You can also just setup the paths, but this is faster/simpler. Might screw up your Cygwin though).
-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).
-Open up avr.cmake (or arm.cmake) in your favourite text editor.
-You are looking for:
+ ----------
+| ARM EABI |
+ ----------
+
+Download the latest version of Mentor Graphics Sourcery CodeBench ARM EABI.
+
+http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/editions/lite-edition/
+
+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".
+
+Use the installer and make sure you add the binaries to your path within the installer.

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
-(TODO, not complete, avr and arm are different currently, need to be unified)

+To load the newly built firmware:

+Rather than use a special program that can interpret Raw HID, this controller exposes a USB Serial CDC endpoint.
