如何在Arduino上捕获AT命令的输出?如何在Arduino中读取AT命令的输出?
我使用带GSM屏蔽的Arduino Uno R3。我有所有的AT命令(they can be seen here),如果我使用终端并获得输出,我可以很好地输入它们。但是,如何通过代码捕获结果输出?下面的代码显示了我尝试过的,但它不起作用。特别是在我尝试获取模拟输入并打印出结果的地方。
#include <SoftwareSerial.h>
SoftwareSerial mySerial(7, 8);
void setup()
{
char sensorValue[32] ="";
Serial.begin(9600);
mySerial.begin(9600);
Serial.println("\r");
//Wait for a second while the modem sends an "OK"
delay(1000);
//Because we want to send the SMS in text mode
Serial.println("AT+CMGF=1\r");
delay(1000);
mySerial.println("AT+CADC?"); //Query the analog input for data
Serial.println(Serial.available());
Serial.println(Serial.read()); //Print out result???
//Start accepting the text for the message
//to be sent to the number specified.
//Replace this number with the target mobile number.
Serial.println("AT+CMGS=\"+MSISDN\"\r");
delay(1000);
Serial.println("!"); //The text for the message
delay(1000);
Serial.write(26); //Equivalent to sending Ctrl+Z
}
void loop()
{
/*
if (mySerial.available())
Serial.write(mySerial.read());
if (Serial.available())
mySerial.write(Serial.read());
*/
}
我得到的输出:
AT + CMGF = 1
AT + CADC? 21 13
或
AT + CMGF = 1
AT + CADC?不管我的模拟信号源的变化18 65
好的,我已经构建了一些代码来检查available()然后读取,但是我只是返回我刚才输入的命令,如何获取命令发回的结果? – BOMEz 2012-04-26 21:48:47
您可以测试可用性并从myserial中读取。 – 2012-04-27 17:06:41
