Thread: Teensy 3.5 pins

    Teensy 3.5 pins

    Sorry if this is a dumb question, but I cannot find any reference to what Pins 24 and 25 on the Teensy 3.5 can be used for - there is no indication on the pin-out diagram, and all the other pins have some designation.

    Again apologies for such a dumb question, but any help would be appreciated.

    You can use them as a normal digital pin. I.e. use digitalWrite to make the pin go low or high, and digitalRead to read the status of the pin. As you said, there isn't anything specifically that uses the pin.

    You can also use them with attachInterrupt(), because it's supported on all digital pins.
