Arduino Uno或PHP

Question

我想使用Google Maps API获取地理位置坐标，将其发送到Arduino Uno，然后将消息解析为一个浮点数数组。

我已经使用strok()有,作为分隔符，但我无法解析的文字和括号中的短信。

我只需要将坐标解析为一个float数组。

Answer 1

我使用strok（）函数自行解决了

{
     const char *delim  = "(";   //a '(' is the delimiter
     const char *delim1  = ",";
     const char *delim3  = ")";
     char *text;
     char *firstItem;
     char *secondItem;
     char *thirdItem;
     char *fourthItem;
     char *fivethItem;
     char *sixthItem;
     char *seventhItem;
     char *eighthItem;
     text = strtok(password,delim);
     firstItem = strtok(NULL,delim1);
     secondItem = strtok(NULL,delim3);
     secondItem++;
     thirdItem = strtok(NULL,delim1);
     thirdItem++;
     fourthItem = strtok(NULL,delim3);
     fourthItem++;
     fivethItem = strtok(NULL,delim1);
     fivethItem++;
     sixthItem = strtok(NULL,delim3);
     sixthItem++;
     polyX[0] = atof(firstItem);
     polyY[0] = atof(secondItem);
     polyX[1] = atof(thirdItem);
     polyY[1] = atof(fourthItem);
     polyX[2] = atof(fivethItem);
     polyY[2] = atof(sixthItem);
     memset (password,NULL,sizeof(password));
}
