I do, but I'm working on getting the upper layers to work correctly. First, interrupts are failing miserably which I'll try to sort out today. Second, PWM mode doesn't work in non-root user mode, so I am going to implement software PWM for that run mode (with a user warning). Lastly, I need to rewrite the state mechanisms and cleanup routines, as I don't like when a crash happens that pins stay in an inconsistent state.
Once all those are done, I'll add more features. I've also got a couple of other XS modules that are specific to sensors (DHT11 hygrometer for example) that I need to brush up a little.
My goal was to get it far enough to be able to create my indoor grow operations environment control centre (which I've pretty well done), but then I thought I'd take it the whole way so that Perl has an easy-to-use implementation of wiringPi that goes beyond just the core library itself (management of components/pins, safe cleanup etc).
fwiw, the most recent code is here. DHT11 code is RPi::DHT11::EnvControl.
