Getting this compile error when I try to upload the ParallelOutputDemo code to my teensy 3.1 - any ideas?

What version of arduino and what version of teensyduino are you using?

arduino 1.0.5 and teensyduino 1.18!

That’s a fairly old version at this point, update to teensyduino 1.21

Ah that fixed it thank you!
