Hello! Ultimately I don't care what you use this for. It's intended to be
|
|
educational, and perhaps to the oddly minded - a little bit of fun.
|
|
Please hack this, change it and use it in any way you see fit. You acknowledge
|
|
that I am not responsible for anything bad that happens as a result of
|
|
your actions. However this code is protected by GNU GPLv3, see the license in the
|
|
github repo. This means you must attribute me if you use it. You can view this
|
|

|
|
Cheers!

Background
|
|
~~~~~~~~~~
|
|
A very minimal example of using the Logitech SDK to interface with a keyboard display,
|
|
then uses a really sloppy implementation of sockets, to connect to a twitch chat
|
|
session, displaying the chat on the keybaord screen.
|
|
|
|
Future Modifications
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
1) Wrap around text display on screen
