I2C was initially invented by Philips as a simple 2-wire low-speed communications interface between CPUs and simple peripherals. Used primarily in embedded systems to connect things like I/O devices, it is now used, under various names, by most IC manufacturers on many System-on-chips. This seminar will introduce I2C and the I2Cdev API which allows you to write I2C drivers from userspace in Linux.

PocketBeagle

For 2018 we will be using the PocketBeagle.

All the Embedded Apprentice Linux Engineer classes will involve using embedded hardware during the hands-on labs. We will be using the PocketBeagle and a BaconBits cape which are included with the $75 USD registration fee for E-ALE at SCaLE61x and ELC. We will only support doing the labs on the official HW kit; please don't bring your own and try to use that. The HW kits will be delivered to the attendee at the first seminar they choose to attend.

Pocket Beagle and Breadboard

The BaconBits is OSHW and available on github

The BaconBits cape has the following capabilities:

• USB Host A

• Reset button

•  I2C accelerometer

•  GPIO Push button

• Power button
