The Kiibohd Controller
|
|
======================
|
|
|
|
This README is a bit long, just look at the sections you are interested in.
|
|
You only need to install avr-gcc if you want to build for the Teensy 2.0/2.0++.
|
|
Everything else needs an arm-none-eabi-gcc compiler (e.g. Infinity keyboard,
|
|
Teensy 3.0/3.1, McHCK).
|
|
|
|
Linux is the ideal build environment (preferably recent'ish). In the near
|
|
future I'll make available an Arch Linux VM for building/manufacturing tests.
|
|
|
|
Building on Mac should be ok for 99% of users with Macports or Homebrew. For
|
|
Homebrew, use `brew tap PX4/homebrew-px4` to get the arm-none-eabi-gcc installer.
|
|
The dfu Bootloader will not build correctly with the old version of
|
|
arm-none-eabi-gcc that Macports currently has (4.7.3). This is due to a bug
|
|
with lto (link time optimizations) which makes the resulting binary too big to
|
|
fit on the chip (must be less than 4096 Bytes).
|
|
|
|
Building on Windows should also be fine for 99% of users, but takes a bunch of
|
|
work to setup (because Windows is a crappy dev environment). Cygwin is
|
|
currently required along with some non-Cygwin compilers and utilities (because
|
|
they are not available for Cygwin). The dfu Bootloader will not build because
|
|
of a Make 3.81+ bug/feature that removed support for non-Unix (Windows)
|
|
filenames as dependencies of targets. If you [replace the version of Make in
|
|
Cygwin](http://stackoverflow.com/questions/601516/cygwin-make-error-target-pattern-contains-no)
|
|
it should work. However, make sure that the flash size is no larger than 4096
|
|
Bytes or the bootloader will not work. Things will likely break if there are
|
|
**SPACES IN YOUR PATHS**. I install cygwin to `C:\cygwin64`. If you are brave
|
|
and have programming knowledge, I will accept patches to fix any issues
|
|
regarding spaces in paths.
|
|

General Dependencies
|
|
--------------------
|
|
|
|
Below listed are the Arch Linux pacman names, AUR packages may be required.
|
|
|
|
These depend a bit on which targets you are trying to build, but the general
|
|
one:
|
|
|
|
- cmake (2.8 and higher)
|
|
- git
|
|
- ctags (recommended, not required)
|
|
- python3
|
|
- libusb1.0 (and -devel)
|
|
- make
|
|
|
|
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)
|
|
|
|
ARM Specific (Teensy 3.0/3.1, Infinity Keyboard, McHCK)
|
|
|
|
- Arch Linux / Mac Ports
|
|
- arm-none-eabi-gcc
|
|
- arm-none-eaby-binutils
|
|
|
|
- Windows (https://launchpad.net/gcc-arm-embedded/+download)
|
|
- gcc-arm-none-eabi (win32.zip)
|
|
|
|
|
|
Windows Setup
|
|
-------------
|
|
|
|
Compiling on Windows does work, just it's a bunch more work.
|
|
|
|
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
|
|
- python3
|
|
- ctags (recommended, not required)
|
|
|
|
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)
|
|
(3+ is ideal) - Select "Do not add CMake to system PATH". 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'/bin:'${PATH}' cmake -G 'Unix Makefiles'\"" >> ~/.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](http://www.atmel.com/tools/atmelavrtoolchainforwindows.aspx).
|
|
The latest should be fine, as of writing it was 3.4.3.
|
|
|
|
Extract the files to a directory, say `C:\avr8-gnu-toolchain`. Then copy all
|
|
the folders in that directory to the Cygwin `/usr/local` directory. Mine is
|
|
`C:\cygwin64\usr\local`. (You can also just setup the paths, but this is
|
|
faster/simpler. Might screw up your Cygwin though).
|
|
|
|
|
|
### ARM EABI
|
|
|
|
Download the latest
|
|
[GNU Tools for Embedded Processors
|
|
gcc-arm-none-eabi](https://launchpad.net/gcc-arm-embedded/+download).
|
|
|
|
Download `gcc-arm-none-eabi*win32.zip`.
|
|
|
|
Then extract all the folders/files in the zip to the Cygwin `/usr/local`
|
|
directory. Mine is `C:\cygwin64\usr\local`. Or, you can setup paths using
|
|
the installer (you have to be more careful, avoid spaces in paths).
|
|
|
|
|
|
CMake Info
|
|
----------
|
|
|
|
One of the big benefits of using CMake is the ability to build multiple
|
|
configurations (for different microcontrollers) at the same time. The
|
|
following sections explain in detail what each CMakeLists.txt configuration
|
|
option does and what you can change it to. However, it is possible to
|
|
configure each of these options using the `-D` command line flag.
|
|
|
|
For example, to build the Infinity Keyboard default configuration:
|
|
|
|
```bash
|
|
$ mkdir build_infinity
|
|
$ cd build_infinity
|
|
$ cmake -DCHIP=mk20dx128vlf5 -DScanModule=MD1 -DMacroModule=PartialMap \
|
|
-DOutputModule=pjrcUSB -DDebugModule=full -DBaseMap=defaultMap \
|
|
-DDefaultMap="md1Overlay stdFuncMap" -DPartialMaps="hhkbpro2" \
|
|
..
|
|
$ make
|
|
```
|
|
|
|
CMake defaults to the values specified in CMakeLists.txt if not overridden via
|
|
the command line.
|
|
|
|
> NOTE: On Windows, you will have to use "wincmake" instead of "cmake".
|
|
|
|
|
|
Selecting Microcontroller
|
|
-------------------------
|
|
|
|
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.
|
|
|
|
Open up CMakeLists.txt in your favourite text editor. You are looking for:
|
|
|
|
```cmake
|
|
###
|
|
# Chip Selection
|
|
#
|
|
|
|
#| You _MUST_ set this to match the microcontroller you are trying to compile for
|
|
#| You _MUST_ clean the build directory if you change this value
|
|
#|
|
|
set( CHIP
|
|
# "at90usb162" # Teensy 1.0 (avr)
|
|
# "atmega32u4" # Teensy 2.0 (avr)
|
|
# "at90usb646" # Teensy++ 1.0 (avr)
|
|
# "at90usb1286" # Teensy++ 2.0 (avr)
|
|
# "mk20dx128" # Teensy 3.0 (arm)
|
|
"mk20dx128vlf5" # McHCK mk20dx128vlf5
|
|
# "mk20dx256" # Teensy 3.1 (arm)
|
|
CACHE STRING "Microcontroller Chip" )
|
|
```
|
|
|
|
Just uncomment the chip you want, and comment out the old one.
|
|
|
|
> NOTE: If you change this option, you will *need* to delete the build
|
|
> directory that is created in the Building sections below.
|
|
|
|
|
|
Selecting Modules
|
|
-----------------
|
|
|
|
> WARNING: Not all modules are compatible, and some modules may have
|
|
> dependencies on other modules.
|
|
|
|
This is where the options start getting interesting. The Kiibohd Controller
|
|
is designed around a set of 4 types of modules that correspond to different
|
|
functionality:
|
|
|
|
- Scan Module
|
|
- Macro Module
|
|
- Output Module
|
|
- Debug Module
|
|
|
|
The Scan Module is where the most interesting stuff happens. These modules
|
|
take in "keypress data". A converter Scan Module will interpret a protocol
|
|
into key press/releases. A matrix Scan Module may inherit from the matrix
|
|
module to scan keypress from a matrix This module just has to give
|
|
press/release codes, but does have some callback control to other modules
|
|
depending on the lifecycle for press/release codes (this can be very
|
|
complicated depending on the protocol). Each Scan Module has it's own default
|
|
keymap/modifier map. (TODO recommend keymap changing in the Macro Module).
|
|
|
|
Some scan modules have very specialized hardware requirements, each module
|
|
directory should have at least a link to the needed parts and/or schematics
|
|
(TODO!).
|
|
|
|
The Macro Module takes care of the mapping of the key press/release code into
|
|
an Output (USB) scan code. Any layering, macros, keypress
|
|
intelligence/reaction is done here.
|
|
|
|
The Output Module is the module dealing with output from the microcontroller.
|
|
Currently USB is the only output protocol. Different USB output
|
|
implementations are available, pjrc being the safest/least featureful one.
|
|
Debug capabilities may depend on the module selected.
|
|
|
|
The Debug Module enables various things like the Teensy LED on errors, debug
|
|
terminal output. (TODO get true UART working in avr, not just arm)
|
|
|
|
Open up CMakeLists.txt in your favourite text editor. Look for:
|
|
|
|
```cmake
|
|
###
|
|
# Project Modules
|
|
#
|
|
|
|
#| Note: This is the only section you probably want to modify
|
|
#| Each module is defined by it's own folder (e.g. Scan/Matrix represents the "Matrix" module)
|
|
#| All of the modules must be specified, as they generate the sources list of files to compile
|
|
#| Any modifications to this file will cause a complete rebuild of the project
|
|
|
|
#| Please look at the {Scan,Macro,Output,Debug} for information on the modules and how to create new ones
|
|
|
|
##| Deals with acquiring the keypress information and turning it into a key index
|
|
set( ScanModule "MD1"
|
|
CACHE STRING "Scan Module" )
|
|
|
|
##| Provides the mapping functions for DefaultMap and handles any macro processing before sending to the OutputModule
|
|
set( MacroModule "PartialMap"
|
|
CACHE STRING "Macro Module" )
|
|
|
|
##| Sends the current list of usb key codes through USB HID
|
|
set( OutputModule "pjrcUSB"
|
|
CACHE STRING "Output Module" )
|
|
|
|
##| Debugging source to use, each module has it's own set of defines that it sets
|
|
set( DebugModule "full"
|
|
CACHE STRING "Debug Module" )
|
|
```
|
|
|
|
Look at each module individually for it's requirements. There is
|
|
chip/architecture dependency checking but some permutations of modules may not
|
|
be tested/compile.
|
|
|
|
There are also CMake options for temporarily selecting modules. But it's
|
|
easier to just edit the file. e.g. `cmake -DScanModuleOverride=<module name>`.

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. 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`.

Linux Loading Bootloader
|
|
------------------------
|
|
|
|
> NOTE: Does not apply to Teensy based builds.
|
|
|
|
It's recommended to use an SWD-type flasher like a Bus Pirate. There is a
|
|
convenience script for loading the firmware once the system is setup.
|
|
|
|
```bash
|
|
$ cd Bootloader/Scripts
|
|
$ ./swdLoad.bash
|
|
```
|
|
|
|
The above script requires Ruby, Ruby serial port module, git, and a
|
|
`/dev/buspirate` udev rule.
|
|
|

Windows 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 Interface and using the `reload` command.
|
|
|
|
The `load` script that is created during the build can load the firmware over
|
|
USB.
|
|
|
|
To load the newly built firmware: `./load`
|
|
|
|
Be patient the couple of times, Windows is slow at installing drivers...
|
|
|
|
|
|
Mac OS X Building
|
|
-----------------
|
|
|
|
From this directory.
|
|
|
|
```bash
|
|
$ mkdir build
|
|
$ cd build
|
|
$ cmake ..
|
|
$ make
|
|
```
|
|

Mac OS X Loading Firmware

|
|
pressing the re-flash button on the PCB/Teensy. Or by entering the Kiibohd
|
|

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`.
|
|
|
|
```
|
|
$ screen /dev/ttyACM0
|
|
# (Might be ACM1, ACM2, etc.)
|
|
```
|
|
|
|
### Windows
|
|
|
|
Make sure the Teensy Virtual Serial Port driver is installed. If possible use
|
|
screen (as part of Cygwin). Check which COM port the virtual serial port has
|
|
been assigned to: `Device Manager->Ports (COM & LPT)->Teensy USB Serial`. In
|
|
brackets it will say which COM port (e.g. COM3)
|
|
|
|
putty works well when using DTR/DSR or RTS/CTS flow control.
|
|
|
|
| Setting | Value |
|
|
| --------------- | ------------------------------------- |
|
|
| Connection type | Serial |
|
|
| Serial line | Your COM port, e.g. COM3 |
|
|
| Speed | doesn't matter, it's auto-negotiated |
|
|
|
|
Under `Category->Connections->Serial`: `Flow control: DTR/DSR`.
|
|
|
|
If stuff is hard to read (you have a dumb colour scheme):
|
|
`Category->Window->Colours->Use system color`. That seems to make text at
|
|
least readable
|
|
|
|
> I use a custom colour scheme that makes each colour easy to see.
|
|
> -HaaTa.
|
|
|
|
Unfortunately, screen for Cygwin seems to be broken for serial ports, but you
|
|
can try it...
|
|
|
|
```bash
|
|
$ screen /dev/ttyS2
|
|
# 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...
|
|
|
|
### Mac OS X
|
|
|
|
I recommend screen (can be installed via Macports).
|
|
|
|
```bash
|
|
$ screen /dev/tty.<usb something>
|
|
```
