Changes

If you have a recent version of the All-In-One circuit, you are lucky, as it includes an extra row-pin connector (SW1) that allows to easily use this extra GPIO ports. If you don't, you have to solder your wires directly to the MCP23107 pins. Not difficult at all, but not really nice.

This is the pin assignment for the row-pin connector (SW-1):

This is the pin assignment for the row-pin connector (SW1):

* pin 1 => GND

* pin 1 => GND

So, if you have a recent version of All-In_Circuit, you can follow these simple steps for adding your custom switches:

* Update your zynthian

* Solder the 5 row-pin connector to your All-In-One circuit

* Solder the 5 row-pin connector to your All-In-One circuit (SW1)

* Connect some kind of switch between pins 2-5 and pin 1 (GND). The switches are normally open, closing to pin 1 (GND).
