Support for Raspberry Pi 3 #25

Open winternet-studio opened 7 years ago

winternet-studio commented 7 years ago

For my Raspberry Pi 3 it doesn't detect the right version number in Pi->getVersion(). It returns 0 instead of 4. Therefore I can't use certain pins without it complaining. I would have made a pull request if I could but I don't know how to convert the revision numbers (http://www.raspberrypi-spy.co.uk/2012/09/checking-your-raspberry-pi-board-version/)

Hey, I've just tested a couple of things on my Pi and seems to be ok. Can you attach the contents of your /proc/cpuinfo?

winternet-studio commented 7 years ago

Of course...

The Pi 3 by the way also has quite an extra number of GPIO pins: 5, 6, 12, 13, 16, 19, 20, 21, 26 (source: http://raspi.tv/wp-content/uploads/2014/07/Raspberry-Pi-GPIO-pinouts-1024x703.png - even though it says B+ it is the same for version B2 and B3)

Bad news for you is, I've tested with that cpu info file and I get 10625154 from ->getVersion(). Meaningless, but it should be working for you.

I'm not the maintainer of this library - I was just going to make the PR for you.

If you get desperate, you could try this library in the meantime.

Sorry, not time left nor budget to try this so far, Please feel free to share a PR here
