OutputPrint

OutputPrint class provides print() and println() methods and String class from Wiring / Arduino library.

OutputPrint class can use any file descriptor as output, by default "stdout" if defined, and add a dummy "Serial" instance to emulate Arduino Serial.print() function. Can run on any libc/libc++ compatible system, like MacOS, FreeBSD, Linux, even Windows.

For Serial.print() reference see: https://www.arduino.cc/reference/en/language/functions/communication/serial/print/

For String class reference see: https://www.arduino.cc/reference/en/language/variables/data-types/stringobject/
