Compiling errors with Aurora + Smartled V4 + Teensy 3.6

Hi All,

I am having issues trying to get Aurora working, the Smartled V4 works without any issues using the demo files included with the library, but Aurora keeps crashing while trying to compile.

Arduino: 1.8.9 (Linux), TD: 1.47, Board: "Teensy 3.6, Serial, 180 MHz, Faster, US English"

thanks for your help in advance!

I didn’t take a look at all the errors but I see:

  • You have two .INO files in the Aurora folder, that’s not right
  • What is “NoUseGifDecoder” in libraries and why is it being included?
  • AJson may have been updated since Aurora was last updated and the return type of at least one method has changed, maybe you can use an older version, or update Aurora to match

Thanks for your feedback Louis.

I managed to get it working, (kind of, as it seems that I don’t have the proper remote/ir receiver), but here is what I did.

I am using the latest branch for Aurora/Teensy 3.6:
https://github.com/pixelmatix/aurora/tree/sm3.1-teensy3.6-64x64

Using the latest version of aJson:
https://github.com/interactive-matter/aJson
I also tried a prior version that was supposed to fix some compilation issues as indicated here, but I was getting the same errors.

At the end I edited aJson library following this reference:
https://gitlab.com/xarduino/lightsw/blob/master/patch/ajson-void-flush.patch, and this finally let me compiled the code for Teensy 3.6 :slight_smile:

btw, I also edited the Aurora.ino because I don’t have the audio adapter (link), and changed some references:

From: #include <GifDecoder.h>
To: #include “GifDecoder.h”

And on Animations.h:
From: #include <FilenameFunctions.h>
To: #include “FilenameFunctions.h”

Depending on what you’re looking for, if you just want the Aurora demos, you can find them here as separate code:

And if you just want the gif decoder, you can find it here:


(it’s an updated fork of Louis’ code)
