Ruby on the Pi

Mon Sep 29, 2014 1:28 pm

Hi all! I'm a ruby dev! :)

I'd like to learn/port over some Python/C to Ruby for the community.

So far I have:
* Installed all kinds of Ruby on the Pi
* Hooked my Pi up to a 16x32 display and ran C/Python on it.

I'd like to try using Artoo ( ... ry-pi-gpio), but there's something odd going on here!

Lake a look at the connecting-to-raspberry-pi section, where they talk about the GPIO #17. You may notice that normally pin 17 is +3.3v... I think they're confused in their diagram. Am I correct, or am I misunderstanding the GPIO numbering system?

Help is mucho appreciated!

Pin 17 on the expansion header is indeed 3V3. gpio17 is brought out to pin 11 on the expansion header.

Because both of my Pis are model Bs, I have a printed copy of
to help with all of the confusing names for the pins.
