Hi all,
I have a Teensy 3.1 with a SparkFun TeensyView on it. I've successfully programmed a couple times before.
But now I find that when I plug it in to my Mac's USB port, Arduino 1.8.7 is no longer detecting it as a USB serial device.
The thing that's changed is that I hooked up a 4x6 keypad matrix to pins 0-4, 6-9 and 12.(The TeensyView is using pins 5,10,11,13 & 15.)
(I should have breadboarded this first, but I was in a hurry and thought "what could possibly happen?")
My question is: could these new pin hookups have something to do with the Teensy not being detected? Are there pins shared with the USB port, for instance?
Any other theories would also be much appreciated. Thanks!
