In case instead of dealing with C String formatting sprintf concat string and int or even char buffers.
Just do this if it just has to go on the same debug line:
Serial.print(speed);
Serial.print("m/s :: ");
Serial.print(speed * 3.6);
Serial.println("km/h");
some print and a println at the end. "1.00m/s :: 3.60km/h"
I prefer using some helper methods for simple printing:
inline void mPrint(Stream&) {}
template <class H, class... Tail> void mPrint(Stream& stream, H const head, Tail const... tail) {
stream.print(head);
mPrint(stream, tail...);
}
template <class... Args> void mPrintln(Stream& stream, Args const... args) {
mPrint(stream, args..., "\r\n");
}
Usage:
mPrintln(Serial, 1, ':', 2, ':', 3, '.', 99); // Saves six lines of code.
awsome, I will include the template in my lib, thank you
