Trying to test the attach interrupt function in the ArduinoIDE and on teensy3. This compiles and loads with the teensyduino beta6. I have a wire between 13 and 0 and I get no pulses counted in the ISR. The loop counts and runs, I see the pulse_train going 1 and 0 and the led is flashing. I assume I am doing something wrong. I use similar code in a breadboard with a Mega and count pulses from a pump and it works flawlessly. I am investigating moving this to a Teensy3 and wanted to investigate this function. I assume I am doing something wrong. Why do I get no ISR service?.
