Neopixel.cpp works with 2.0 but not 3.1

[heliboy]

I have been using the adafruit neopixel library (strandtest example). If the board is set to teensy 2.0 it compiles (1.0.5-r2) fine and works. BUT if the board is set to teensy 3.1 it spits out a whole bunch of errors about ..Neopixel.cpp. Anybody know what this is about ?

Follow up comment. Works fine with octoWS2811 library so the hell with the Adafruit neopixel library.

Are you using Teensyduino 1.18?

I just tried it here. Compiles without any error.

I haven't tried it yet, but Dan Garcia said that the 2.1 branch of the FastLED Library is working with Teensy 3.1.

FastLED replaces the FastSPI.LED2 library

Note, Adafruit added the Teensy 3.1 support about 3 months ago, so make sure you have the latest version from adafruit and as Paul says the full 1.18 release. If you look in the Adafruit_Neopixel.cpp file, you should see the following around lines 665:

#elif defined(__arm__)

#if defined(__MK20DX128__) || defined(__MK20DX256__) // Teensy 3.0 & 3.1
