I'm interested in the topic, my new Teensy 4.0 cannot access I2C buses to control devices I already tested with 3.2 and 3.6.
Any news about development?
Any suggestion about how to add some modification to the last library version to make it work (even modification not very efficient) for T4.0?
Thank you anyway
Sorry, I don't have anything running on T4 at the moment. I acquired some parts, but I haven't had time to work on it. For now you will have to utilize the Wire library.
