SD: Report the switches in binary format¶
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.
Get the raw hardware debounced switch state for every switch, in binary format. This command is similar to
SA:, except with binary results instead of ASCII.
SD: command response includes the physical state of each switch. If you configured the switch to report inverted, that only affects the
-L messages, not this
There is no
<CR> sent on the end of this response
Response: (because this is binary it will often contain ASCII characters which will not be printable)
SD: #/^ ! +
