A basic GPS/GNSS receiver based on mosaicHAT and Arduino. The Arduino code reads GPS/GNSS data (NMEA format) messages from mosaicHAT, a Raspberry Pi compatible PCB based on Septentrio's mosaic-X5, and shows desired data on LCD display.
mosaicHAT Arduino: Making the mosaicHAT work with Arduino
Author: (Jamal Sa'd) [email protected]
The code is based on the following connections:
The Arduino program expects NMEA GGA messages from mosaicHAT serial (COM2). To configure mosaic-X5, connect the board to PC via USB and open mosaic webUI on default address "192.168.3.1"
- Go to the Communication tab and choose Serial.
- Change the baud rate of COM2 to 9600.
- Click Ok for changes to take effect.
- Go to NMEA/SBF Out and choose New NMEA Stream.
- Select Serial connection type then COM2 as connection/port.
- Keep the default interval (1 sec) and select GGA as a message to output.
- Click Ok for changes to take effect.
- Now a popup message will ask if you would like to save the current configuration as a boot configuration. Choose Save.
This project makes the following deliverables for both integrators and designers of systems around Septentrio's mosaic modules.
