Re: FIRST IR module driver released
Jacob,

I saw in your code that you're restricting the inputs to IOs 1-6 because they have selectable pullup resistors. This isn't necessary. The outputs of the IR board can sink 8.5mA when driven low, which is easily enough to counteract any pullup resistor. Admittedly, this would be a problem if the IR outputs went to High-Z when there wasn't a signal, but i think it's safe to assume that as long as they have power, they're driving the outputs between high and low and thus you don't have to worry about pullups.
