GPS display

This unit gives a lot of GPS information on a 40 character by 4 lines display.

The schematic is based on a microBlox module, this GPS has to be initialized in order to give NMEA data. The software for the PIC16F876 can be downloaded here.

It is not necessary to use the microBlox since NMEA is used. For other NMEA GPS modules, this program for the PIC can also be used.

All components were solderen on a plain PCB, no traces but just copper surface because there are just a few components used.

The final display:

The layout of the display is as follows:

If the GPS unit supports the GPZDA line, the local time is display instead of UTC. If the GPS does not support knots, the PIC will calculate the speeds from the GPRMC or other lines containing speeds over ground.
