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, we have a series of programming guides. Also, be sure to read the overview of how FSP works and how to connect first.


Lamp Byte (Writes 8 bits at a time; 1 = lamp on, 0 = off)



F0 in the above example is 11110000, so that would turn on lamps 4-7 and turn off lamps 0-3.


Starting with lamps 8-15, turn on lamp 15, 23, 31, 39, All other lamps in the range of 8-39 are off.
