【问题描述】:
我正在尝试将Arduino Uno 与 skm53 GPS 模块连接,但是在使用 Arduino 软件上传草图之前,我对其进行了验证并发现了以下错误。
错误:#error NewSoftSerial 自 1.0 版起已移入 Arduino 核心。请改用 SoftwareSerial。
我在Arduino工具的libraries目录下包含了TinyGPS和NewSoftSerial这两个库,我搜了一下发现几乎所有的代码都和我的一样。
#include <TinyGPS.h>
#include <NewSoftSerial.h>
unsigned long fix_age;
NewSoftSerial GPS(2,3);
TinyGPS gps;
void gpsdump(TinyGPS &gps);
bool feedgps();
void getGPS();
long lat, lon;
float LAT, LON;
void setup(){
GPS.begin(9600);
//Serial.begin(115200);
}
void loop(){
long lat, lon;
unsigned long fix_age, time, date, speed, course;
unsigned long chars;
unsigned short sentences, failed_checksum;
// Retrieves +/- latitude/longitude in 100000ths of a degree.
gps.get_position(&lat, &lon, &fix_age);
getGPS();
Serial.print("Latitude : ");
Serial.print(LAT/100000,7);
Serial.print(" :: Longitude : ");
Serial.println(LON/100000,7);
}
void getGPS(){
bool newdata = false;
unsigned long start = millis();
// Every 1 seconds we print an update.
while (millis() - start < 1000)
{
if (feedgps ()){
newdata = true;
}
}
if (newdata)
{
gpsdump(gps);
}
}
bool feedgps(){
while (GPS.available())
{
if (gps.encode(GPS.read()))
return true;
}
return 0;
}
void gpsdump(TinyGPS &gps)
{
//byte month, day, hour, minute, second, hundredths;
gps.get_position(&lat, &lon);
LAT = lat;
LON = lon;
{
feedgps(); // If we don't feed the GPS during this long
//routine, we may drop characters and get
//checksum errors.
}
}
