Bringup: GPS UART #2

Open rgov opened 9 months ago

rgov commented 9 months ago
Function Pin
PIO_2_UART_TX GP8
PIO_2_UART_RX (from GPS) GP9

Need to program a PIO UART state machine (like the auxiliary UART).

TBD depending on the GPS module. uBlox outputs NMEA, the MetOcean iBCN has a complicated protocol. TX may not be needed at all.

CircuitPython module for NMEA strings from Adafruit.

CircuitPython module for PIO UART from Adafruit. At the time of writing, it has only had a single commit 5 months ago, so it may not actually work.
