Support for GPS on Serial2 port #5

Open

kh4 wants to merge 1 commit into nixiebunny:main from kh4:serialgps

kh4 commented Mar 5, 2022

These changes add support for having a GPS receiver connected on the Serial2 port of the Teensy.

Some notes on the changes

GPS connected on USB takes priority
default baudrate is 9600 (I might look into autobauding later)
GPS TX connected to pin 11 (GPIO9/RX2)
GPS RX connected (optionally) to pin 12 (GPIO10/TX2)
tested with BN180 GPS , in practice any NMEA GPS should work
GPSage limit increased to 1500ms as with 1Hz update rate 1000ms can cause a glitching
