Part 2 LINUX to control GPIO's and interact with I2C.

Jim Merkle will be presenting Part 2 of how to use LINUX to control GPIO's and interact with I2C.
We will be interacting with the DS3231 RTC. (Bring yours if you have one.)
The Raspberry Pi 3 with the latest Raspbian OS will be used during the demonstrations.

What to Bring:

  • Raspberry Pi, any model, or BeagleBone.
  • Monitor, Keyboard & mouse and USB and video cables.
  • Don't forget your power cords and your laptop.
  • DS3231 module, LED(s) with limiting resistors, breadboard and jumper wires.
  • DS3231 will be available for $2.00 each.

    To make things easy please use Raspberry Pi with latest OS Raspbian Jessie w/Pixel to match what will be presented.
