Neogps library and Tft display

[mustafa-ozlu]

Hi, i wrote a code for displaying gps nmea sentences to tft display. But my code not display results. Display all sentences 0.00 Where is my fault.

include

static const uint32_t GPSBaud = 38400;

include

static NMEAGPS gps; static gps_fix fix;

define gpsPort Serial

define GPS_PORT_NAME "Serial"

else

define ADJ_BASELINE 0
