Convert char* to uint8_t

Question

I transfer message trough a CAN protocol.

To do so, the CAN message needs data of uint8_t type. So I need to convert my char* to ui

Answer 1

More safe example in C++ way

char* bufferSlidePressure = "123";
std::string buffer(bufferSlidePressure);
std::stringstream stream;

stream << str;
int n = 0;

// convert to int
if (!(stream >> n)){
    //could not convert
}

Also, if boost is availabe

int n = boost::lexical_cast( str )
