GPS Digital Compass PIC Project

This PIC16F628-based compass uses NMEA-0183 data from a GPS receiver. The direction indicator displayed on eight-point LED with radial pattern every 45°. Although the GPS provides accuracy to a tenth of a degree, that kind of accuracy is not really necessary in the automotive use for which project is designed.
