I'm working on an arduino assignment that splits an incoming string and puts the terms of the string in 6 different variables( a sample input string when split up has 6 terms). i have the following error popping up: cannot convert 'String' to 'char*' for argument '1' to 'c...
an example from the Ethercard library. I am able to get data, but I'm having difficulty converting it into a string. Data comes in as a pointer byte (?) (like byte*) and I can easily convert it into a const char*. From,
To use thetoInt()functionto convert acharto anintin Arduino, you’ll first need to convert thecharto aStringand then use thetoInt()function. voidsetup(){Serial.begin(9600);charcharValue='7';StringstringValue(charValue);intintValue=stringValue.toInt();Serial.println(intValue);}voidloop()...
; // 定义一个Char数组 String strings[10]; // 定义一个字符串数组,用于存储拆分后的字符串 int stringCount = 0; // 记录拆分后的字符串数量 void setup() { Serial.begin(9600); // 遍历Char数组并拆分成独立的字符串 char temp[50]; // 临时Char数组,用于存储当前的子字符串 int tempIndex...

ConvertStringtocharUsing thetoCharArray()Function in Arduino This method copies the string’s characters to the supplied buffer. It requires two inputs, one is a buffer to copy the characters into, and the other is the buffer size. voidloop(){String stringOne="A string";charBuf[50];string...
extractLetters(morseCode.substring(startPos1, endPos1)); // This function would extract Letter as name suggest and would convert code to text SIMPLE! startPos1 = endPos1 + 1; if (startPos1 == morseCode.length()) { break; } endPos1 = morseCode.indexOf('#', startPos1); ...
I want to get this code to recognise different commands and be able to parse the rest of the command, fore example I send "/sleep 5", and it will sleep for 5 seconds. However, I keep on getting this error "cannot convert 'String' to 'const char*'". here is my ...
