keybrd library for creating keyboard firmware
|
|
====================================================
|
|
keybrd library is an open source library for creating custom-keyboard firmware.
|
|
The resulting keyboard firmware is compatible with standard USB keyboard drivers.
|
|
|
|
keybrd library can support any keyboard configuration:
|
|
* one-piece
|
|
* split with I/O expander
|
|
* single-layer
|
|
* multiple-layer
|
|
|
|
Multiple-layer keyboards can write symbols without using the shift key:
|
|
|
|
~ ! @ # $ % ^ & * () _ {} | < > : ?
|
|
|
|
keybrd library leverages the Arduino environment to create keyboard firmware.
|
|
The Arduino development environment is free, and easy for novice programmers to setup and learn.
|
|
|
|
The keybrd library has been tested on the Teensy 2.0 microcontroller, MCP23018 I/O expander, and PCA9655E I/O expander.
|
|
|
|
> The public API should not be considered stable.
|
|
> Currently the keybrd library is limited to 8x8 matrices, which is enough for compact split keyboards.

Example minimal keybrd sketch
|
|
-----------------------------
|
|
<!-- todo after teensy LC bb, copy and remove annotations from keybrd_single-layer_2_annotated.ino -->
|
|
A [minimal keybrd sketch](tutorials/keybrd_2_single-layer_annotated/keybrd_2_single-layer_annotated.ino).
|
|
has about 50 lines of code and runs on a 4-key keyboard.
|
|
It runs on a breadboard and has rows, columns, and diodes just like the big keyboards.
|
|
The sketch is small because the keybrd library takes care of the low-level details.
|
|
|
|
The keybrd tutorial 1 shows how to make a breadboard keyboard.
|
|
The [keybrd tutorials](tutorials) 2, 3, and 4 show how to create custom keybrd firmware.
|
|
|
|
Example complex keybrd sketch
|
|
-----------------------------
|
|
The keybrd_DH emulates the DataHand keyboard.
|
|
It has 72 keys, 4 layers, a sub-layer, 2 matrices, and many features.
|
|
The keybrd_DH and its instantiation files contain about 800 lines of code.
