Neuron Controller: FAST Serial Protocol Overview

FAST Serial Protocol: Overview & First Steps

This documentation section is about the FAST Serial Protocol (FSP) commands, which are the low-level commands a host computer sends to a FAST board. Most FAST Pinball makers do not need to know about these details, since the pinball game framework (such as the Mission Pinball Framework) handles this communication for you.

If you're writing your own game framework, read the overview of how FSP works and how to connect first.

When you connect to a FAST Neuron Controller via USB, you will see three virtual serial ports appear. The exact port names and numbers will vary depending on your computer, but they will always be in the same relative order.

So we talk about the "first port" or "third port", and that could be:

COM4, COM5, COM6

Or it could be:

/dev/tty.usbmodem1101, /dev/tty.usbmodem1103, /dev/tty.usbmodem1105

Regardless of the actual port names, the relative ports on a Neuron Controller connect to the following processors:

  • First Port: NET
  • Second Port: EXP
  • Third Port: DSP
