Invert GPIO

Open videojedi opened this issue 8 years ago • 3 comments

Hi, Firstly, great implementation. Thank you very much! Using it on a show as we speak. Just one request, would it be possible to have an option to invert the GPIO? I have used a standard off the shelf(amazon) relay unit that interfaces with the Pi really well, observing the 3.3v requirements of the Pi. But the relay unit is Active-low and so whilst I can connect the tallies to the normally closed terminals, it means the unit will 'Fail On' if the power is interrupted and all camera tallies come on. (I have found it best not to confuse cameraman!)

Thanks again,

Richard.
