The CSG library is used to display information on Comfile Technology's 7-segment display devices. Each CSG device must have a unique I2C slave address configured by a dipswitch on the back of the device.

Up to 4 CSG devices can be daisy-chained together to make a longer composite display. Each device must have a different slave address.
