Hi @Louis @Jason
I started again from scratch. Deleted all traces of my old folders, etc. Followed instructions given to compile Aurora https://github.com/pixelmatix/aurora/wiki/Compiling
Fresh Arduino 1.6.5 install
Installed Teensyduino 1.23 to Arduino install directory plus,
-DS1307RTC
-IRremote
-Time
Add .zip source Library via Arduino application. They ended up in the sketchbook directory in \Libraries with the following folder names
- aJson-master
- FastLED-3.0.3
- SmartMatrix_32x32
Deleted RobotIRemote from Arduino /libraries folder
Copied Aurora 1.6 source sketch to my sketchbook folder and rename to aurora. The directory then has folder:
Aurora–/
------------- .h files and aurora.ino
-------------Bin (Folder)
-------------sd (Folder)
Libraries–/
---------------aJson-master (Folder)
---------------FastLED-3.0.3 (Folder)
---------------SmartMatrix_32x32 (Folder)
Open Aurora.ino
Change CPU to Teensy 3.1 and CPU to 96MHz optimised overclock
Click Verify
