|
|
----------------------
|
|
|
|
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
|

|
|
|
#| Specify the compiler family to use
|
|
#| Currently only supports AVR and ARM
|
|
#| "avr" # Teensy 1.0

|
|
#| "arm" # Teensy 3.0
|
|
|
|
set( COMPILER_FAMILY "avr" )
|
|
|
|
|
|
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.

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).
|
|
|
|
Open up avr.cmake (or arm.cmake) in your favourite text editor.

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
|
|
- USB 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).
|
|
|
|
|
|
The Macro Module takes care of the mapping of the key press/release code into a USB scan code.
|
|
Any layering, macros, keypress intelligence/reaction is done here.
|
|
|
|
|
|
The USB Module is the output module of 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 setup.cmake in your favourite text editor.

# 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,USB,Debug}/module.txt 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 "avr-capsense" )
|
|
|
|
##| Uses the key index and potentially applies special conditions to it, mapping it to a usb key code
|
|
set( MacroModule "buffer" )
|
|
|
|
##| Sends the current list of usb key codes through USB HID
|
|
set( USBModule "pjrc" )
|
|
|
|
##| Debugging source to use, each module has it's own set of defines that it sets
|
|
set( DebugModule "full" )
|
|
|
|
|
|
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

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.
