.. highlight:: cpp .. _lang-highbyte: highByte() ========== (Macro) Extracts the second lowest byte of an integral data type. .. warning:: This macro is provided for compatibility with Arduino only. It returns the second-least significant byte in an integral value. It makes sense to call this the "high" byte on a 16-bit ``int`` microcontroller like the Atmel chips on Arduinos, but it makes no sense at all on a 32-bit microcontroller like the STM32s in the Maple line. In short: we provide this so that existing Arduino code works as expected, but **strongly discourage its use** in new programs. Syntax ------ :: highByte(x) Parameters ---------- **x**: a value of any integral type. Returns ------- Second lowest byte in **x**. Example ------- :: int x = 0xDEADBEEF; SerialUSB.println(x, HEX); // prints "BE" Arduino Compatibility --------------------- The Maple version of ``highByte()`` is compatible with Arduino.
