    I think your question is too vague for anyone to really help you. If you let us know what device you want to connect to the T4, there might already be a library out there that can help you.

    You can share the same I2C bus as long as the devices have different addresses. Mouse example code here: https://www.pjrc.com/teensy/td_mouse.html If you don't have the datasheets for the I2C devices that you...
