回复：带有 neo 6m GPS 和按钮的 Arduino

Question

我是航空专业的学生，刚接触编码环境。我目前正在使用 Arduino mega 2560 开发 GPS neo 6m 模块，我想在按下按钮时保存当前位置。按下按钮将使用哪个功能来保存位置。这是我到目前为止所做的。任何帮助将非常感激。提前致谢。

#include <SoftwareSerial.h>
// The TinyGPS++ object
TinyGPSPlus gps;
static const int RXPin = 4, TXPin = 3; //gps module connections
static const uint32_t GPSBaud = 9600;
// The serial connection to the GPS device
SoftwareSerial ss(RXPin, TXPin);

const int PUSH_BUTTON = 2;

void setup(){
    pinMode(PUSH_BUTTON, INPUT_PULLUP); //push button input
    
    Serial.begin(9600);
    ss.begin(GPSBaud);
} 

void loop(){
  unsigned char i;
  static const double homeLat = 12.334455, homeLon = 05.112233;


  while (ss.available() > 0){
    gps.encode(ss.read());
    if (gps.location.isUpdated()){
      Serial.print("Latitude= "); 
      Serial.print(gps.location.lat(), 6);
      Serial.print(" Longitude= "); 
      Serial.println(gps.location.lng(), 6);
    }

    
    status = digitalRead(PUSH_BUTTON);
    if (status== HIGH){
          *missing code/confused*

    }  
  
    delay(1000);
  }
}```

Answer 1

只需将值存储在 2 个变量中即可。

    #include <SoftwareSerial.h>
    // The TinyGPS++ object
    TinyGPSPlus gps;
    static const int RXPin = 4, TXPin = 3; //gps module connections
    static const uint32_t GPSBaud = 9600;
    // The serial connection to the GPS device
    SoftwareSerial ss(RXPin, TXPin);
    
    const int PUSH_BUTTON = 2;
    double save_lat, save_lang;
    void setup(){
        pinMode(PUSH_BUTTON, INPUT_PULLUP); //push button input
        
        Serial.begin(9600);
        ss.begin(GPSBaud);
    } 
    
    void loop(){
      unsigned char i;
      static const double homeLat = 12.334455, homeLon = 05.112233;
    
    
      while (ss.available() > 0){
        gps.encode(ss.read());
        if (gps.location.isUpdated()){
          Serial.print("Latitude= "); 
          Serial.print(gps.location.lat(), 6);
          Serial.print(" Longitude= "); 
          Serial.println(gps.location.lng(), 6);
        }
    
        
        status = digitalRead(PUSH_BUTTON);
        if (status== HIGH){
 if (gps.location.isUpdated()){
             save_lat = gps.location.lat();
    save_lang = gps.location.lng();
        }  
      }
        delay(1000);
      }
    }
