Beaglebone Coding 101: I2C

The GigaMegaBlog is at it again with another great Beaglebone tutorial.  This time they breakdown how to use I2C devices with the Beaglebone.

In previous articles in the Beaglebone 101 series, I covered digital GPIOanalog and serial pinsPWM and SPI.

One important coding interface remains: I2C.  I’ll cover it today, including I2C input and output, and level conversion, culminating in the Weatherbone, a basic LCD-based thermometer.

They use a whole bunch of Adafruit goodies, including the i2c / SPI character LCD backpack, Standard LCD 16×2, and the Adafruit Proto Cape Kit for Beagle Bone.

New from the fine people who have brought us the Beagle Board, we now have a smaller, lighter, but powerful single board linux computer, Beagle Bone! We like this move to a more compact and integrated SBC. For example, there is onboard Ethernet and USB host, as well as a USB client interface (a FTDI chip for shell access). It even comes preloaded with Angstrom Linux on the 4 GB microSD card!
