求助帖关于GPS时间转换成北京时间的
求助社区里的各位大佬，怎么在下面的代码加个让GPS获取的时间在1602LCD屏幕上实时显示出来，我找了好多资源都用不了:'(#include <TinyGPS.h>
#include <LiquidCrystal.h>
TinyGPS gps;
LiquidCrystal lcd(12, 11, 2, 3, 4, 5); //LCD driver pins
int led = 13;
long lat, lon;
unsigned long fix_age, time, date, speed, course;
unsigned long chars;
unsigned short sentences, failed_checksum;
//int year;
//byte month, day, hour, minute, second, hundredths;
int DEG;
int MIN1;
int MIN2;
void LAT(){ //Latitude state
DEG=lat/1000000;
MIN1=(lat/10000)%100;
MIN2=lat%10000;
lcd.setCursor(0,0); // set the LCD cursor position
lcd.print("LAT:");
lcd.print(DEG);
lcd.write(0xDF);
lcd.print(MIN1);
lcd.print(".");
lcd.print(MIN2);
lcd.print("' ");
}
void LON(){ //Longitude state
DEG=lon/1000000;
MIN1=(lon/10000)%100;
MIN2=lon%10000;
lcd.setCursor(0,1); // set the LCD cursor position
lcd.print("LON:");
lcd.print(DEG);
lcd.write(0xDF);
lcd.print(MIN1);
lcd.print(".");
lcd.print(MIN2);
lcd.print("' ");
}
void setup()
{
Serial.begin(9600); //Set the GPS baud rate.
pinMode(led, OUTPUT);
lcd.begin(16, 2); // start the library
lcd.setCursor(0,0); // set the LCD cursor position
lcd.print("GPS test"); // print a simple message on the LCD
delay(2000);
}
void loop()
{
while (Serial.available())
{
digitalWrite(led, HIGH);
int c = Serial.read(); // Read the GPS data
if (gps.encode(c)) // Check the GPS data
{
// process new gps info here
}
}
digitalWrite(led, LOW);
gps.get_position(&lat, &lon, &fix_age); // retrieves +/- lat/long in 100000ths of a degree
gps.get_datetime(&date, &time, &fix_age); // time in hhmmsscc, date in ddmmyy
//gps.crack_datetime(&year, &month, &day, //Date/time cracking
//&hour, &minute, &second, &hundredths, &fix_age);
LAT();
LON();
}
$GPRMC,095609.00,A,3057.64xxx,N,12126.69xxx,E，GPRMC后面的一串数字是UTC时间，+8个小时就是北京时间了:lol
