I have been trying to find out how to access the PPS line from the GPS with no luck.
Are there schematics to show which pin the PPS would be connected to and how to configure for the PPS to be enabled? I have found the PPS configuration in u-center but have not had any luck in finding which GPIO it would be attached to on the Pi.
The PPS is planned to be used for tight time synchronization.
I am using Navio2 and Raspberry Pi 4B w/ NEO-M8N.
