Support for C.H.I.P.

Hi,

First of all, great library! I use it to control my porch light through a component in Home Assitant. I recently migrated my setup from a RPi to a C.H.I.P. and noticed that this package does not work anymore. This because RPi.GPIO of course only works on a RPi. However there is a (almost) drop-in replacement for this dependency called CHIP_IO. The only method that CHIP_IO seems to lack is GPIO.setmode.

With this patch a got the library working on the C.H.I.P.:

If you are willing to add support for C.H.I.P. I could make a PR out of this patch.

Cheers!

Hello guys, i started porting rpi-rf (that i love) to CHIP using the new CHIP_IO.GPIO from @xtacocorex It’s working now… or sort of… you can check it out here https://github.com/nunojusto/CHIP-rf/

The problem is that i cannot have clear results and i’, working directly with CHIP_IO guy to solve some of the error. Please try and help if you can 😃 Thankx

EDIT: Oops, i see that “chrisvis” is advanced on it also. Lets share common problems.

I think it would make more sense to make the module injectable by some means. This could then also be used for Beaglebone black with Adafruit_BBIO.
