I have 2 XBee S2 routers. The settings for Analog Pins 0 thru 3 are set to ADC . One XBees is mounted on a Jaycon Systems explorer board and the other on an adapter board.
Currently I have nothing attached to the sensor pins, just configured. The samples for the pins are all coming into my Netduino as follows:
Analog Pin 0 0211 = ( 529 0.62052785923753662 )
Analog Pin 1 0210 = ( 528 0.61935483870967745 )
Analog Pin 2 020E = ( 526 0.61700879765395888 )
Analog Pin 3 020F = ( 527 0.61818181818181817 )
I was expecting them to be 0 since nothing is connected.
Am I missing something in my understanding here? I am afraid to connect sensors in that I might send too much voltage & burn out the pins.
Thanks for your thoughts.
