Hey folks. I am using the sparkfun XBee shield w/the teensy 3.1 and I have some problems. My hot prob is that A6 is acting bonkers. All my analog pins will do an analogRead just fine except A6. A6 is just stuck at like 986. If I touch the pad with the jumper I have plugged in to my circuit 's sensor she jumps to 1021 and does not move even if I change the sensor output.
Now here's the weird bit - it behaves perfectly as an analogWrite pin - no issues at all. It gladly goes from 0-3.3V no problems as expected.
I can promise you all this isn't a code issue (I teach pcomp for a living at the University level and have an MS from an Engineering school).
Why is only this pin being weird. It's consistent.
Thoughts? Anyone else seen this? It's a first gen teensy 3.1 and I bought it out of the vending machine at NYU resistor. She's legit hardware.
Now my bottom row of header pins are soldered in tossing just the teensy on a breadboard isn't an easy affair. It's my last one!
