Massive WS2812 Scroll Display!
Posted: Sat Jul 09, 2016 1:07 pmHi Guys!
I'm currently building this HUGE scroller
https://wp.josh.com/2016/05/20/huge-scrolling-arduino-led-sign/comment-page-1/#comment-7623
The whole thing is controlled by a Arduino UNO, but I would really love to use an ESP8266 for this. The problem is that the code created to control this is not compatable. Can you guys please help me get this working on a ESP8266?
Here is a link to the code:
https://github.com/bigjosh/MacroMarquee/blob/master/Arduino/MacroMarquee/MacroMarquee.ino
At the start of the code my first problem starts:
Then a piece of assembly code starts wich shouldn't be a problem, but there are two :: in there which the compiler does not like:
Thanks for the help!
