i have few questions about the Teensy 3.1.
I was looking at the PulsePosition.h library, and noticed few things that I do not understand:
1 - There is a Serial.print(val); but no Serial.begin(9600); . How does it work?
2 - I can use val = analogRead(0); without declaring the pin pinMode(0, INPUT);. Isn't necessary to declare the pins before use ?
3 - What is Vbat?
4 - Can I power the teensy though regulated 3.3V on the 3.3V pin?
Thank you,
Francois
