Hello all !
I try to compile wavfileplayerUSB example from arduino 1.6.11/teensyduino 1.30 (fresh install) and it fail, i have this error:

Error compiling for board Teensy 3.2 / 3.1.

I tried to change include <wire.h> by include <i2c_t3.h> in Audio cpp files, but it didnt change anything :-(
Is anyone have an idea ?
Thanks for your help !

I was able to build it for T3.6 just now using Arduino 1.6.12 and 1.31 beta2 (Note the Audio library I used is a (git) copy of Pauls github version, so I my build has a few more updates than the beta2 release (like support for DAC1), but i don't think that should impact the build.

thanks KurtE
i was able to build it too with Arduino 1.6.12 and 1.31beta2 (for Teensy 3.2). It worked because the source of wavFilePlayerUSB has changed: it is now wire.h in the including list !
I tried to change it with "i2c_t3.h" and it give the same result... Unable to compile with i2c_t3 :-(

 

[KurtE]

Yes, you can not mix the two libraries as they both try to create the same name objects and define the same Interrupt handlers...

 

[sreyn]

Yes I agree, i would like to use i2c_t3.h only... I dont know where are the others reference to wire.h

I guess, it is inside the audiolibrary.

it's ok now, it's located in control_ak4558.cpp, control_sgtl5000.cpp, control_cs4272.cpp, control_wm873.cpp
