How to read a string value with a delimiter on Arduino?

Question

I have to manage servos from a computer.

So I have to send manage messages from computer to Arduino. I need manage the number of servo and the corner. I\'m thinking

Answer 1

It's universal parser

struct servo
{
    int iServoID;
    int iAngle;
};

std::vector split(const std::string& str, const std::string& delim)
{
    std::vector tokens;
    size_t prev = 0, pos = 0;
    do
    {
        pos = str.find(delim, prev);
        if (pos == std::string::npos) pos = str.length();
        std::string token = str.substr(prev, pos-prev);
        if (!token.empty()) tokens.push_back(token);
        prev = pos + delim.length();
    }
    while (pos < str.length() && prev < str.length());
    return tokens;
}

std::vector getServoValues(const std::string& message)
{
    std::vector servoList;
    servo servoValue;
    std::vector servoString;
    std::vector values = split(message, ",");
    for (const auto& v : values)
    {
        servoString.clear();
        servoString = split(v, ";");
        servoValue.iServoID = atoi(servoString[0].c_str()); //servoString[0].toInt();
        servoValue.iAngle = atoi(servoString[1].c_str());// servoString[1].toInt();
        servoList.emplace_back(servoValue);
    }
    return servoList;
}

to call:

std::string str = "1;233,2;123";
std::vector servos = getServoValues(str);
for (const auto & a : servos)
    std::cout<

Result

1 233
2 123
