Hello :slight_smile:

Using sprintf is the easiest solution I think.

int var;

chat str[] = "M1:1023;";
sprintf( str, "M1:%d;", &var );
// var is now = 1023

Not with sprintf you won't. That will put "M1:308" into the variable str (where 308 is the address of the variable "var").

I think you meant sscanf().
