Warning

This is the dev documentation for an unreleased version of MPF!

This is the documentation for MPF 0.56, which is the “dev” (next) release of MPF that is a work-in-progress. Unless you’re specifically looking for this version, you probably want to use the version of documentation called “latest” which is for the latest released version of MPF. That documentation is at docs.missionpinball.org/en/latest.

How to configure “number:” settings

All of the physical “hardware” mechanisms in MPF config files have a number: setting which is used by the hardware platform to know which device is which.

Since MPF supports many different types of hardware, the exact way you configure the “number” entry depends on what type of device and what type of hardware you’re using.

We have full guides that explain it all in the hardware controller documentation, but here are the links all in one place to make it easy.
