你好!我一直在尝试使用 NodeMCU ESP8266 和 NEO6M GPS 模块为我的学校项目构建一个 GPS 跟踪器。问题是我之前设法毫无问题地完成了它。但后来我把它原封不动地放了大约一个星期。
今天我尝试打开 NodeMCU,然后我得到了那个脚本。“未检测到 GPS:检查接线。”
代码:
全选#include
#include
#define BLYNK_PRINT Serial
#include
#include
sta
tic const int RXPin = 4, TXPin = 5 ; // GPIO 4=D2(conneect Tx of GPS) and GPIO 5=D1(Connect Rx of GPS
static const uint32_t GPSBaud = 9600; //if Baud rate 9600 didn't work in your case then use 4800
TinyGPSPlus gps; // The TinyGPS++ object
WidgetMap myMap(V0); // V0 for virtual pin of Map Widget
SoftwareSerial ss(RXPin, TXPin); // The serial connection to the GPS device
BlynkTimer timer;
float spd; //Variable to store the speed
float sats;
String bearing; //Variable to store orientation or direction of GPS
char auth[] = "----"; //Your Project authentication key
char ssid[] = "tt"; // Name of your network (HotSpot or Router name)
char pass[] = "ayyyyylmao"; // Corresponding Password
//unsigned int move_index; // moving index, to be used later
unsigned int move_index = 1; // fixed location for now
void setup()
{
Serial.begin(115200);
Serial.println();
ss.begin(GPSBaud);
Blynk.begin(auth, ssid, pass);
timer.setInterval(5000L, checkGPS); // every 5s check if GPS is connected, only really needs to be done once
}
void checkGPS(){
if (gps.charsProcessed() < 10)
{
Serial.println(F("No GPS detected: check wiring."));
Blynk.virtualWrite(V4, "GPS ERROR"); // Value Display widget on V4 if GPS not detected
}
}
void loop()
{
while (ss.available() > 0)
{
// sketch displays information every time a new sentence is correctly encoded.
if (gps.encode(ss.read()))
displayInfo();
}
Blynk.run();
timer.run();
}
void displayInfo()
{
if (gps.location.isValid() )
{
float latitude = (gps.location.lat()); //Storing the Lat. and Lon.
float longitude = (gps.location.lng());
Serial.print("LAT: ");
Serial.println(latitude, 6); // float to x decimal places
Serial.print("LONG: ");
Serial.println(longitude, 6);
Blynk.virtualWrite(V1, String(latitude, 6));
Blynk.virtualWrite(V2, String(longitude, 6));
myMap.location(move_index, latitude, longitude, "GPS_Location");
spd = gps.speed.kmph(); //get speed
Blynk.virtualWrite(V3, spd);
sats = gps.satellites.value(); //get number of satellites
Blynk.virtualWrite(V4, sats);
bearing = TinyGPSPlus::cardinal(gps.course.value()); // get the direction
Blynk.virtualWrite(V5, bearing);
}
Serial.println();
}
我没有改变任何东西,它只是因为某种原因停止工作。
我的 GPS 模块与 NodeMCU 之间的连接是:-
VCC ~ 3V
RX ~ D1
TX ~ D2
GND ~ GND
以前每当我插入电缆时,nodemcu 和 GPS 模块都至少闪烁一次。连接成功后会一直闪烁。但现在似乎只有 nodemcu 以闪烁响应。
GPS 模块完全没有反应。没有眨眼没有什么。
帮我弄清楚这个
