USB LED Badge Programmer

Word of warning

This is just a very early development state / work in progress.
No fancy GUI, just a simple commandline

Why ?

I got this neat little LED badge on a promotion sale. Unfortunately i didn't found a software to use it under Linux. So I decided to make one.

Info

This project provides a very basic way to programm a USB LED badge with text and graphic messages under Linux.
It is developed under code:blocks, so there is no makefile available at the moment.
It works for the XANES X1 DIY Bicycle Taillight. The Leadbike LD45 seems to use the same hardware. This badges are rechargeable and connects to the PC via USB as HID class devices. They support up to 8 messages that can be displayed all one after another or each one alone.

Software

What is done so far:

• Protocol reverse engineered (see ./doc/)
• udev rule created (see ./doc/)
• core routine to communicate with badge
• example programm (cli only, no graphic import yet)

ToDo:
a lot.. maybe a GUI

Usage

Commandline options:

-h  Show help.
-i  Set message index [0..7].
-m  Set message text.
-s  Set the message speed [1..8].
-e  Set the message effect [0..8].
    0: to left
    1: to right
    2: scroll up
    3: scroll down
    4: Freeze
    5: Animation
    6: Snow
    7: Volume
    8: Laser
-b  Blink message.
-f  Set frame for message.
-B  Set the badge brightness [0..3]. This is for all messages.
-D  Demo mode. Use as the only argument.

badge -i[0..7] -m <text for message num i> <parameter for message num i> (next index with message and parameter ...)

Examples:

badge -i0 -m "Hello World!" -e2 -s6

• writes one up scrolling message to slot 0 of the badge with speed 6

badge -i0 -m "Hello World!" -e2 -s6 -i6 -m "there is more.." -e1 -f

• writes 2 messages to slot 0 and 6

badge -i0 -m "This" -e1 -s6 -i1 -m "is a" -e0 -f -i2 -mTest

• writes 3 messages, slots 0,1,2 to the badge

Installation and software setup

(not much at the moment)

udev
Copy the udev rule to the rules directory, e.g.
sudo cp ./doc/99-led_badge_test.rules /etc/udev/rules.d/
Depending on your system, it might be necessary to trigger/reload udev
sudo sudo udevadm trigger
sudo reload udev
Mostly, it should work to copy the rule and then plug in the device.
