I'm trying to understand enough of the TS4231 to get it to operate FDM (frequency division multiplexing) with gen 1 valve lighthouses. If testing goes well, I will move from an ESP8266 to an ESP32 and from one sensor per processor to 4 or 8.
The TS4231 has a "legacy" mode that works without issue with gen1 lighthouses, however, the legacy mode does not provide carrier information. If we can get this working, we should be able to do house- or warehouse- scale tracking with gen1 lighthouses by using different carrier frequencies for each lighthouse, axis and sync pulse.
This can be fun for Halloween - having a cranium head flow around to music people, or for a portray with eyes that follow you to get tracking signals.
