I2C working on RoboRIO
Today's effort was trying to get the I2C working on the RoboRIO. Evidently, the on-board I2C port is /dev/i2c-2 (that's the 3rd port of 3). We wanted to get a generic example of I2C code that could be extended to use any of the dozens of I2C sensors available from places like Sparkfun.

We first got a Linux only program running to prove the port was working at all. Then we ported the application to WPILib. The device was a Sparkfun ADXL345 3-axis accelerometer. Anyone interested in the code is welcome to a copy of both the Linux version and the WPILib version.
