Robo Rio Digital Inputs Question.

On the 2015 controller, Does anybody have the spec for the digital inputs? Do they have pullups? What voltage is high and what voltage is low? We may need to feed a analog signal into a digital input and are trying to figure out if we need additional circuit to chop it.

Re: Robo Rio Digital Inputs Question.

There is a pullup resistor and you can select the power line to be 5v or 3.3v. I'd have to experimentally try the thresholds but 0.7v and 1.4v are typicall thresholds for digital logic.

What kind of sensor are you trying to use and why not use the analog inputs?
