BOE bug ? ?
Before I start dissecting my BOE I thought I'd ask if there is a known bug in it. When I DEBUG INH & INL in binary, it seems that when I jumper P13 hi or lo it shows up in the P12 bit position (as does P12).

·· Are you using a pull-up or pull-down resistor to keep the I/O line from floating?· If not this could cause what you're seeing.

·· Did you try the suggestion of putting the resistors in place?

I constructed a three story "elevator" as a software project for which the expected operation will be something with which the students will be familiar. It uses 14 inputs from various buttons, plus a servomotor oputput. Figured I had a wiring error, but it ends up being this P13 thing.
