Is it possible to communicate with I²C devices via the GPIO?

Question

Is it possible to communicate with I²C devices via the GPIOs?

Also, are there any existing drivers or libraries that make this possible from Python?

Answer 1

According to the wiki, I2C is exposed on pins 3 (SDA) and 5 (SCL).

Using from Python on Debian (Untested)

Based on reading this forum post.

Run

sudo apt-get install python-smbus

to install the drivers. At the time of writing, there is a test script here.

Note: Someone needs to test this.
