Hi guys and gals of Teensy Land,
I have a home-rolled LC clone here (scavenged a LC bootloader, bought the MCU) and note some interesting voltages on unused pins here. Unlike the PJRC-sourced Teensy LC boards I have (happily blinking away on their default program when plugged into the USB port), the LC clone MKL26Z seems to feature voltages as high as 2.1VDC on 'un-assigned' pins.
Once a particular pin has been assigned a pinmode and the blink program for example, it behaves as expected.
Any idea what might be driving these phantom pin voltages?
