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 (3+ is ideal) - http://cmake.org/cmake/resources/software.html -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. 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 /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: - -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: - - ### - # 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: - - ### - # 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= - - - ----------------------- -Linux Building ----------------------- - -From this directory. -mkdir build -cd build -cmake .. -make - - -Example output: - - [master]: cmake ..

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=`. + + +Linux Building +-------------- + +From this directory. + +```bash +$ mkdir build +$ cd build +$ cmake .. +$ make +``` + +Example output: + +``` +$ cmake .. +-- Compiler Family: +arm +-- Chip Selected: +mk20dx128vlf5 +-- Chip Family: +mk20dx +-- CPU Selected: +cortex-m4 +-- Compiler Source Files: +Lib/mk20dx.c;Lib/delay.c +-- Bootloader Type: +dfu +-- Detected Scan Module Source Files: +Scan/MD1/scan_loop.c;Scan/MD1/../MatrixARM/matrix_scan.c +-- Detected Macro Module Source Files: +Macro/PartialMap/macro.c +-- Detected Output Module Source Files: +Output/pjrcUSB/output_com.c;Output/pjrcUSB/arm/usb_desc.c;Output/pjrcUSB/arm/usb_dev.c; +Output/pjrcUSB/arm/usb_keyboard.c;Output/pjrcUSB/arm/usb_mem.c;Output/pjrcUSB/arm/usb_serial.c +-- Detected Debug Module Source Files: +Debug/full/../cli/cli.c;Debug/full/../led/led.c;Debug/full/../print/print.c +-- Found Git: /usr/bin/git (found version "2.2.1") +-- Found Ctags: /usr/bin/ctags (found version "5.8") +-- Checking for latest kll version: +Current branch master is up to date. +-- Detected Layout Files: +/home/hyatt/Source/controller/Macro/PartialMap/capabilities.kll +/home/hyatt/Source/controller/Output/pjrcUSB/capabilities.kll +/home/hyatt/Source/controller/Scan/MD1/defaultMap.kll +/home/hyatt/Source/controller/kll/layouts/md1Overlay.kll +/home/hyatt/Source/controller/kll/layouts/stdFuncMap.kll +/home/hyatt/Source/controller/kll/layouts/hhkbpro2.kll +-- Configuring done +-- Generating done +-- Build files have been written to: /home/hyatt/Source/controller/build +[master]: make [~/Source/controller/build](hyatt@x230mas:pts/6) +[ 5%] Generating KLL Layout +Scanning dependencies of target kiibohd.elf +[ 11%] Building C object CMakeFiles/kiibohd.elf.dir/main.c.o +[ 17%] Building C object CMakeFiles/kiibohd.elf.dir/Lib/mk20dx.c.o +[ 23%] Building C object CMakeFiles/kiibohd.elf.dir/Lib/delay.c.o +[ 29%] Building C object CMakeFiles/kiibohd.elf.dir/Scan/MD1/scan_loop.c.o +[ 35%] Building C object CMakeFiles/kiibohd.elf.dir/Scan/MatrixARM/matrix_scan.c.o +[ 41%] Building C object CMakeFiles/kiibohd.elf.dir/Macro/PartialMap/macro.c.o +[ 47%] Building C object CMakeFiles/kiibohd.elf.dir/Output/pjrcUSB/output_com.c.o +[ 52%] Building C object CMakeFiles/kiibohd.elf.dir/Output/pjrcUSB/arm/usb_desc.c.o +[ 58%] Building C object CMakeFiles/kiibohd.elf.dir/Output/pjrcUSB/arm/usb_dev.c.o +[ 64%] Building C object CMakeFiles/kiibohd.elf.dir/Output/pjrcUSB/arm/usb_keyboard.c.o +[ 70%] Building C object CMakeFiles/kiibohd.elf.dir/Output/pjrcUSB/arm/usb_mem.c.o +[ 76%] Building C object CMakeFiles/kiibohd.elf.dir/Output/pjrcUSB/arm/usb_serial.c.o +[ 82%] Building C object CMakeFiles/kiibohd.elf.dir/Debug/cli/cli.c.o +[ 88%] Building C object CMakeFiles/kiibohd.elf.dir/Debug/led/led.c.o +[ 94%] Building C object CMakeFiles/kiibohd.elf.dir/Debug/print/print.c.o +Linking C executable kiibohd.elf +[ 94%] Built target kiibohd.elf +Scanning dependencies of target SizeAfter +[100%] Chip usage for mk20dx128vlf5 + SRAM: 32% 5384/16384 bytes + Flash: 18% 23384/126976 bytes +[100%] Built target SizeAfter +``` + +Linux Loading Firmware +---------------------- + +First place the keyboard into re-flash mode.
