Reverse

[thisboyiscrazy]

A lot of times the io is connected to relays the reverse the output. E.G. Gpio goes low, relay closes. It would be nice to have a "reverse" parameter in the constuctor.

So writing 0 to a GPIO sets it to 1 and writing a 1 sets it to 0? 0 would read as 1 and 1 would read as 0?

Exactly.

This should also be possible for inputs. 0 would read as 1 and 1 would read as 0. rising edge interrupts would become falling edge interrupts and falling edge interrupts would become rising edge interrupts.

This is a good idea. I'll add it.

Excellent Thanks

onoff v1.1.0 was just published on npm. The Gpio constructor has an new option called activeLow that can be used to get the desired functionality:

var Gpio = require('onoff').Gpio,
  input = new Gpio(7, 'in', {activeLow: true}),
  output = new Gpio(8, 'out', {activeLow: true});

Thanks.
