Web32.2.2 Endianness. Whenever a type (such as Uint16) is stored as a sequence of multiple bytes, endianness matters:. Big endian: the most significant byte comes first. For example, the Uint16 value 0x4321 is stored as two bytes – first 0x43, then 0x21.; Little endian: the least significant byte comes first. WebA word is 2 bytes (except on Due, Zero and similar boards where it is 4 bytes), which already gets you a huge range of 65536 (256 2). The int data type is a word and Arduino comes with highByte() and lowByte() to extract the left and right byte from a word. This makes it really easy to encode and decode.
