This PR enables the auto-detection of FAST hardware on serial ports. It's a crude, first-draft implementation, but it seems to work well on my hardware.
This change is to support people who use multiple machines to power their hardware, and/or have multiple USB ports that assign different
tty
ports to the same device. With theautodetect
feature, these people don't have to change their hardware config each time they switch computers or USB ports.With the
ports: autodetect
feature, MPF will attempt to find four tty devices with identical, sequential names ending in0-4
orA-D
. If it finds those four, it assumes that the middle two are the FAST Net and RGB devices.It may not be the most performant approach, but this routine is used only once at bootup so it shouldn't be too bad...
