    Pin 30 not working on Teensy 3.2

    So, I bought Teensy 3.2 and everything works fine except for pin 30. Digital write does nothing and analog read gives me values like anything isn't connected. Why is this a problem? Any help would be appreciated.

    I can't say why it's not working for you, but I can confirm it does indeed work if you run this code and connect a LED+resistor.

    void setup() {
      pinMode(30, OUTPUT);
    void loop() {
      digitalWrite(30, HIGH);
      digitalWrite(30, LOW);
    The LED definitely does blink. Here's a photo.
