New here so be gentle…
Just wondering if anyone knows if I can read GPS data using gpsd or similar with the RS485-Pi. My GPS Rx is a commericial timing unit which is RS422 standard.
My project is a GPS Rx testing system, it requires me to have a permanently connected GPS module on ttyUSB0, then I need to be able to temporarily attach the RS422 GPS unit under test and confirm its operation.
Ive bought a usb to rs422 converter but so far can’t workout how to get the gps data out of it.
Any help on this would be great, if I can get this to work on a Pi Zero it would be fantastic.
