NettetA 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. Encode (Arduino): Nettet12. aug. 2024 · Bytes, on the other hand, are used to express storage sizes. 1 byte is equal to 8 bits. This means that one byte can represent 256 (2 8) different states. A byte is usually the smallest unit that can represent a letter of the alphabet, for example. The kilobyte is the next largest unit; it equals 1,024 bytes and can represent 10 3 states. Fact

Nettet19. jan. 2024 · byte datatype has a range from -128 to 127 and it requires very little memory (only 1 byte). It can be used in place of int where we are sure that the range will be very small. The compiler automatically promotes the byte variables to type int, if they are used in an expression and the value exceeds their range. Nettet7. apr. 2024 · Well you have already found the answer: You cannot do that. Signed and unsigned are just different interpretations of the same bit pattern. And that is true, a byte string is an array of 8 bits byte.
