The cpm program can then be invoked to light all four LEDs with the following:
$ cpm -N LED -V 15
The '-N' argument is for specifying the CP group name, and the '-V' argument for specifying which
GPIOs to enable. Below is a high level diagram showing how the CP Manager interfaces with the
GPIO pins.
