New page

One special feature of the Raspberry Pi is its GPIO, or General Purpose Input/Output connector. This is the strip of pins that runs along one side of the Pi, which acts as a connector to a number of physical inputs or outputs.

It is this ability to wire up custom physical inputs, i.e. switches or buttons, that is part of the reason Box Of Stops was written for the Raspberry Pi.

== Setting up a Gpio input ==

There is a section on [http://www.boxofstops.com/hardware#customize-pi Customizing the Raspberry Pi] on the main website. Adding buttons to the Pi is an important part of many hobby projects, so please browse the wealth of information available on this topic.

Once you have wired up a Gpio button, this can be used to control Box Of Stops in exactly the same way as any other [[Trigger]].

If you click the plus icon to add a trigger to a [[Stop]], [[Coupler]] or [[Combination]] in the usual way, then the screen will wait for you to press the new input button. Assuming everything has been wired up correctly, the screen will then confirm which button you pressed.
