Some important notes

This python module handles key coloring of the Drevo Tyrfing v2 keyboard, especially for linux users ; nevertheless it should work under other platforms.

Requirements

dtv2 needs hidapi library: pip3 install hidapi and colour library: pip3 install colour. These dependances are notified in the Pypi setup file, so that if you install via pip command, you have nothing to do.

You may need to install libhidapi-hidraw dynamic library on your system. For debian users: $ sudo apt install libhidapi-hidraw0

Note python hidapi library may confict with python hid library, you may need to uninstall hid library.

Installation

1. Copy the 99-drevo-tyrfing.rules in the /etc/udev/rules.d/ directory to grant user with permissions for to send/write informations to the keyboard. Restart or # udevadm trigger.

2. pip3 install dtv2

Usage

As a module

import dtv2

my_kbd = dtv2.dtv2()

# mem_effect: the more you type the more color change
my_kbd.mem_effect((0, 0, 255), color2=(255, 0, 0), brightness=100)

# radar: rays turn around central key (direction: 0 or 1)
my_kbd.radar((0, 0, 255), color2=(255, 0, 0), brightness=100, speed=100, direction=0)

# static: simple static color or if rainbow=True alternate rainbow colors
my_kbd.static((0, 0, 255), brightness=100, speed=100, rainbow=False)

# breath: breath effect
my_kbd.breath((0, 0, 255), brightness=100, speed=100)

# stream: stream effect (direction = 'n' or 's' or 'e' or 'w')
my_kbd.stream((0, 0, 255), color2=(255, 0, 0), brightness=100, speed=100, direction='e', rainbow=False)

# category: change color of a whole category ('letters', 'digits', 'arrows', 'function', 'mod', 'edition')
my_kbd.category('arrows', (255, 0, 0))

# key_set: list of keys and list of colors
my_kbd.key_set( ['esc', 'space'], [(255, 0, 0), (0, 255, 0)] )
my_kbd.key_set( {'esc': (255, 0, 0), 'space': (0, 255, 0)} )
my_kbd.key_set( [('esc', (255, 0, 0)), ('space',(0, 255, 0)] )
my_kbd.key_set( (('esc', (255, 0, 0)), ('space',(0, 255, 0)) )


# key: simple key color change
my_kbd.key('esc', (255, 0, 0))

For the moment rainbow in static mode can be tricky and affect other effects.

Using simple key or category modes enter personal mode so exit all others. It can be boring to affect each key of the keyboard to the same color so there's this special method in personal mode to change all the keyboard color (and then you can change categories colors and finally some individual keys): kbd

my_kbd.kbd((255, 0, 0))
my_kbd.category('letters', (0, 0, 255))
my_kbd.key('space', (0, 0, 255))

Recap

If you need a monocolor keyboard: static or kbd.

If you want some effects: mem_effect, radar, static (with rainbow) breath or stream.

If you want to personalize categories or some keys: kbd, category key_set and key.

An example usage is provided in the examples directory. It uses colour package to allow human color names instead of hex triplets!

Examples

In the examples section, you'll find a README file to use dtv2change and dtv2reader scripts.

First steps and thanks

I did my first steps in this project with a prefix from:

https://github.com/dennisblokland/DrevoTyrfing

I followed Flozz's tutorial (on a mouse)

So: I used wireshark to find other command prefixes.

USB hid tables (for missing french key codes)

Zer0xFF proposed some changes making individual key color assignments really usable.

onekk added 104-keys keyboard compatibility, support of italian version and other useful things on key categories.

And now?

1. Fix bugs

2. Add functionalities

3. ...
