I’ve tried to recive a valor from the serial input (string) and convert it into a float. There is any function? atof gives me some errores.
I understand that you are using C++
const char*. You can convert
const char* using
c_str() like this.
double numberInDouble = atof(your_string.c_str());
Ok, that seems to work but i’m having another problem. I’m using “getc()” to catch the serial input string. the Error is: A value of type “int” cannot be used to initialize an entity of type “const char *” in “main.cpp”.
So, you are not using
std::string? It would be easier if you post your code.
Why don’t you just put them in a buffer and pass it directly to
char buf; int buf_index = 0; //... buf[buf_index++] = pc.getc(); double numberInDouble = atof(buf);
Hi. Sorry for beeing lost these days, I had some troubles… But I found a easier way to put a float in serial input, I used pc.getc() and introduced “\n” in every number, for example: “120\n” I really don’t know how it works but it actually works haha.
