RS: Update Single LED¶
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.
Note that this legacy RGB command is used with LEDs attached to the ports on a FAST Nano Controller. LEDs attached to the Neuron or other expansion boards are controlled via the EXP Bus connection and use EXP commands, not these RGB commands.
This command is used to update a single LED with new RGB colors. You can also chain multiple LED updates together in a single command.
Command Syntax¶
RS:<ID><R><G><B>,<ID><R><G><B>...<CR>
<ID> is the hex number of the LED to update.
<R>, <G>, <B> are the RGB values (in hex, 0-FF)
Examples¶
RS:040000ff,0500ff00<CR>, LED 4 full on blue, LED 5 full on green
