fast:exp: Config Reference

This is a config file reference. Click for instructions.

This page is reference material which explains every setting and option for this section of an MPF yaml config file. See the instructions for config files for formatting and other details. See our guide to config file examples for more examples of real configs in action.

Valid in
machine config files YES ✅
mode config files NO 🚫

Within the fast: section of your machine-wide config, you configure the EXP processor in the subsection exp:, and sometimes in exp_int:.

port:

List of one (or more) values, each is a type: string. Defaults to auto.

A comma-separated list of the serial port names your FAST controller uses.

baud:

Single value, int, default: 921600

The connection baud rate.

boards:

Dict of string board names to dicts of EXP board properties. Defaults to empty.

Example:

fast:
  exp:
    port: auto
    boards:
      neuron:
        model: FP-EXP-2000
      playfield_0081:
        model: FP-EXP-0081

model:

The product number of the IO board. E.G. FP-EXP-0081

ignore_led_errors:

Single value, boolean, default: false

If false, LED hex communication decode errors will be raised as errors when encountered from this board. If you encounter instability due to these errors, set this to true to silently ignore them.

Using exp_int

If using a Raspberry Pi connected directly to the Neuron controller, the LED headers on the Neuron will not be available on the normal EXP interface. In order to access these Neuron LED headers, you must define a parallel structure to the existing exp: configuration, and move the Neuron definition over to it.

Example:

fast:
  exp:
    boards:
      playfield_0081:
        model: FP-EXP-0081
  exp_int:
    boards:
      neuron:
        model: FP-EXP-2000
