Chippy Gonzales is a tool for directly manipulating the C.H.I.P.'s GPIO hardware-registers, allowing you to query and set things like e.g. mux, pin-state and pull-up/-down.
The tool can also print out a prettyish graph of either of the
C.H.I.P.'s two pin-headers:
Due to directly manipulating the registers it bypasses the Linux-kernel's pinctrl-scheme and you can very much mess things up with it. You should only be using the tool, if you know what you are doing.
