I based this experiment on an article found on ''The Robotics Back-End'' (see References below), but have modified it to use Python rather than C on the Raspberry Pi, since that's the main language I've been using to write the operating system of the [KR01] robot.
I based this experiment on an article found on ''The Robotics Back-End'' (see References below), but have modified it to use Python rather than C on the Raspberry Pi, since that's the main language I've been using to write the operating system of the [KR01] robot. Some of the ideas I found online tended to lock up the I2C bus or cause other kinds of problems. When I stumbled onto an example using the WiringPi library things seemed to even out.

WiringPi (both C++ and Python versions) has an I2C class to provide communication over I2C. The basic API is as follows:

In particular, we can expect to be using the {{wiringPiI2CRead()}} and {{wiringPiI2CWrite()}} methods.
