I've got a little project set-up where I'm reading battery voltage (3.2v nominal). I'm powering the Teensy 3.0 through the USB port. There's no voltage divider and the battery is connected to ground and pin 14 (A0). The program works as intended.
I notice that when I disconnect the USB, and the battery being measured has a large enough voltage, the program continues to run - that is the LED indicating a measurement being taken continues to flash.
Is this normal? Do I have something hooked-up wrong? Thanks!
