Hi, I am working on a project and I am trying to have two teensy's communicate using i2c. I have used the wire.h library, have tried the example code, as well as connecting both teensy's to common ground. I used the master reader and slave writer example code provided by arduino. I used pins 18 and 19 on the teensys. Is there anything else that needs to be done in order to get i2c working between two teensys?
