cpp if (myString.toCharArray(charArray, stringLength + 1) != stringLength) { Serial.println("String to char array conversion failed!"); } 在这个示例中,我们检查了toCharArray方法的返回值,并将其与字符串长度进行比较。如果不相等,则说明转换失败,并输出相应的错误信息。
// convert the incoming byte to a char // and add it to the string: inString += (char)inChar; } // if you get a newline, print the string, // then the string's value: if (inChar == '\n') { Serial.print("Value:"); Serial.println(inString.toInt()); Serial.print("Str...
