您好,我想要 Arduino 上的实时 GPS Sim800 模块 RTC 时间,而不使用库,我可以使用库来实现它,但没有库,正确的数据只需 1 分钟,其他的就会出现垃圾。
请告诉我可以帮助我实现它的代码
使用代码我做了以下事情
#include <SoftwareSerial.h>
SoftwareSerial gsm(10, 11);
String Buffer;
String inData;
int i;
int *year, *month, *day, *hour, *minute, *second;
void setup() {
Serial.begin(9600);
gsm.begin(9600);
delay(5000);
}
void loop() {
Ansh:
delay(500);
gsm.println("AT+CCLK?\r\n");
while (gsm.available()) {
char recieved = gsm.read();
inData += recieved;
delay(100);
// Process message when new line character is recieved
if (recieved == '\n')
{
Serial.print("Arduino Received: ");
Serial.println(inData);
if (inData.substring(1, 5) == "+CCLK") {
Serial.println("Hello");
}
// You can put some if and else here to process the message juste like that:
if (inData == "+++\n") { // DON'T forget to add "\n" at the end of the string.
Serial.println("OK. Press h for help.");
}
inData = ""; // Clear recieved buffer
goto Ansh;
}
/* Buffer = Buffer.substring(Buffer.indexOf("\"") + 1, Buffer.lastIndexOf("\"") - 1);
year = Buffer.substring(0, 2).toInt();
month = Buffer.substring(3, 5).toInt();
day = Buffer.substring(6, 8).toInt();
hour = Buffer.substring(9, 11).toInt();
minute = Buffer.substring(15, 17).toInt();
second = Buffer.substring(18, 20).toInt();
*/
}/*
Serial.println(*hour);
delay(100);
Serial.println(*minute);
delay(100);
Serial.println(*second);
delay(100);
*/
}
但我没有得到实时输出,但在 1 次正确输出后它返回垃圾如下

如果我从代码中删除延迟,那么我会收到以下输出
