Programming Logitech Keyboard to Display Twitch Chat 

For anyone wondering, twitch chat uses the very old (but very good!) IRC-protocol. That should clear up why the returned data looks so odd :)

I can hear a dota 2 stream at the end there. Clearly a smart man. As I'm typing this it comes on screen. Nice.

Heh, sockets are fun. A friend and I discovered a bug in UNIX sockets way back in the day which actually crashed the system: we'd been told about these things in class and decided to cobble up a little "chat" system which basically meant each of us coded a thing which opened the same socket and talked to it: nothing sophisticated, we didn't get that far ;-) Lucky for me, he was the first to compile and run which was when the bug made itself apparent: I say "lucky for me" because that meant his username showed up in the coredump when the techs went to find why their nifty machine had fallen over ;-)

Wonderful work! Imagine this man making an app that allows Logitech G19 to show the actual Twitch video footage. That would be amazing!

This video inspired me to make my own twitch chat bot that does some cool things with the twitch API. I just know basic concepts but it's my first "big" project and quite happy how it's coming along after less than 2 weeks.

I looked at how to do stuff on these panels a while back and gave up. Their docs are functional but no good at helping out newbs like most modern docs are trending toward. Those panels are nifty and it's a shame no one really did anything with them. A few games display logos which is useless. A few do display info but it's actually very unnatural and jarring to look away from the screen and down at your keyboard; Something most of us stopped doing a long time ago. There's a criminal lack of actual apps out there for these panels. The best is one called LCDSirReal which you can still find around the web. It's just a monitor app but it's 10x better than the built in one. Anyway, another great vid from your backlog I'm catching up on, Javid. I might have another go at this sometime.

this is so funny i just had the idea to write a programm to show my own programm on the logitech screen and now you have a kind of tutrial for that XD great

They might not have good software, but that sdk looks really nice to work with

I'd like to see a more in depth WinSock server and client model implementation some time. It looks like using WinSock is pretty hairy. The IRC program mIRC I find handles opening and closing sockets very cleanly in its built-in script editor. It's as easy as: /sockopen switches name ip port You can then just /sockwrite socketname message Ofcourse you need to have supporting code to listen for incoming connections and messages which is also very easy in mIRC. Might be worth a quick look and like I said before, I'd like to see a further dive in to WinSock some day

great video :) thank you

Hi javidx9, ironically I had a G15 v1 keyboard for many years, but it died last year. However I've built and tested this project while stripping out the Logitech API sections. I've registered with Twitch and got my own OAUTH token, but I still can't get this app to read anything form your twitch chat window. Any pointers on debugging this? Wireshark perhaps ?

Good vid

Hey, Nice video ! But I can't get even the most basic c++ template to work even if I did the same things as you. I have a "no target architecture error"

hi there! is it possible to do something like this for Telegram on desktop? or does this only work for IRC-based messages

Ok, I'm struggling a bit with the SDK documentation. Does anyone know if it has access to the power settings of the USB outputs on the keyboard or is this purely for the visual display of the LCD screen?

Sadly I want to do this but having trouble with my lack of knowing what unicode it when I put (L"insert name here" ....) it flags the L

Mmm... i'm wondering if getting some second hand g13 for working purposes with VFX apps and... i think this is a "left handed device" yes but... for right handed users, isn't it ? cause i think the ideal usage for a left handed guy like me would be: mouse or graphic tablet in the left hand and G13 /keyboard in the right hand, RIGHT ? hahaha well... anyways even if there is not a "right handed" version for left handed guys... this looks like an interessting option, thank you very much for thhe unique video

implement word filter on the chat, highlight/remove before showing on LCD xD

can you make something with raspberry pi :D

I've always wanted my G15 LCD to work as a console display for a 'nix system. Anyone have any idea where to start on that?

26:28 D: const_cast at minimum!

Why do you guys still use hungarian(the thing when you put s before variable name to indicate its string) notation when developing in c++ even if todays IDEs can quickly tell you the types when hovering over variable?

Could have used a queue instead of a list

EDIT: LogiLcdInit((wchar_t*)L"G13_tester", LOGI_LCD_TYPE_MONO); solved it (for now :) I'm using your code up to the Hello World part, but I get errors from the lines that use L"text": argument of type "const wchar_t*" is incompatible with parameter of type "chart_t*" and bool LogiLcdInit(wchar_t*,int)':cannot convert argument 1 from 'const wchar_t[11] to 'wchar_t'

I barely know VBA 😔

damn....you use very large font

12:33 the interesting part

Can u program a logitech keyboard to not fucking suck?
