This software may not work on the latest versions of RPi firmware, there is a newer version.

The software for this is free and can be installed following the instructions on the RPi Software installation page. There is an I2C section.

Following the installation the program is run by opening an LX Terminal and typing the following:

python swsi2c.py

This is the opening screen, pressing discover will reveal all of the I2C device on the BUS. Enter the i2c address in the box and press open. Only SWS devices will open the correct dialog as they have been programmed in.

When the I2C address has been entered and the 'Open Selected' button is pressed the device type 4603 in this case is found and the appropriate dialog is opened.

In this case it is the BV4603 motor controller.

For further details see the particular device.
