I have this problem. A long time ago a skill level away, I designed some simple hardware. The connector was like this:
VCC Di A C GND VCC Do B D GND
But i need to interface it onto a connector like this
VCC D0 D1 D2 D3 D4 D5 D6 D7 GND
Can anything go wrong if one of the pins of a PORT (set to input without pullups) is hardwired directly to VCC and one to the GND?
(Yes, I know it's a bad design practice, but the hardware is already done)
