special-purposes-keyboard

🐍 Python 3 CLI utility to programming special purposes keyboard

This is an multi-OS implementation of programming a special purposes keyboard:

Usage scenario

Edit layout file.
Program special purposes keyboard by this utility with command-line interface.

Advantages of this utility

You may have several layout files.
Not need to use GUI to program and even for edit layout file (Unix way 🤖).
Multi-OS usage. Feel free. 🤠

Layout file

Key programming pattern:

key=symbol

  where:
key    - special purposes keyboard key;
symbol - keyboard/mouse action to do.

Symbols examples:

multi-key sequence:
a,b,c

with special keys:
ctrl+shift+alt+meta+a

the same:
c+s+a+m+a

multi-key sequence:
c+s+a+m+a,b,c

For knob programming use section with name Kn for knob n. Example:

[K1]
left=<-
right=->
press=enter

For keys programming use KEYS section. Example:

[KEYS]
1=a
2=s+b
3=a+s+c,d,e

Available knobs and keys depends of special purposes keyboard model.

For rgb leds mode, use LED section. Example:

[LED]
mode=1

3 modes are available :

0 : switched off
1 : pulsing last pressed key (alternating RGB)
2 : continuous 'snake like' pattern

See layout file complete example: layout.ini

And another example: layout_volume_play.ini

Available symbols

Here's the list of the symbols usable in the layout files, mapped on a ISO (105 keys) keyboard

Programming

Be aware that USB subsystem access needs relevant rights. sudo for Kubuntu.

Install Python requirements before usage:

pip install -r requirements.txt

Command line help:

python3 ./keyboard_program.py -h
usage: keyboard_program.py [-h] [-l FILEPATH] [-d] [-v]

Programming utility of special purposes keyboard with encoders and keys.

options:
  -h, --help            show this help message and exit
  -l FILEPATH, --layout FILEPATH
                        keyboard layout file path; default: layout.ini
  -d, --dry             don't iteract with keyboard. Set this option to validate keyboard layout file
  -v, --verbose, -v     verbose level; use multiple times to increase log level; example: -vv

Special keys: CTRL, SHIFT, ALT, META or WIN. Example: "ctrl+shift+alt+meta+<-" or "c+s+a+m+<-". Example
multi-key sequence: "a,b,c" or "c+s+a+m+a,b,c". Known special keyboard USB Vendor:Product: 1189:8890.

sudo python3 ./keyboard_program.py -l "layout.ini" -vd

USB data exchange log scenario on Linux-based machines

# 1. Attach special-purposes-keyboard by USB

# 2. Get USB bus number of keyboard USB connection:
lsusb
# Example out (keyboard is attached to bus 1):
# Bus 001 Device 006: ID 1189:8890 Acer Communications & Multimedia

# 3. Enable USB log by usbmon kernel module:
sudo modprobe usbmon

# 4. Write USB log to keyboard-program.log file (stay this console running while USB logging):
#    1u is for bus 1. You can also filter device using grep (... | grep 1:006 >> ...)
sudo cat /sys/kernel/debug/usb/usbmon/1u >> keyboard-program.log

# 5. Run "MINI KeyBoard.exe" on VirtualBox. Check USB access are granted

# 6. Program
# 6. Add label to USB log file (that help to analyze programming byte sequence):
echo "DOWNLOAD KEY1 = A" >> keyboard-program.log
# 6.1 program KEY1 = A with "MINI KeyBoard.exe"

# 7. Repeat p.6 for another keys/mouse/LED programming

# 8. Stop USB log (press <Ctrl+C> in console)
