WebAug 9, 2024 · std::int8_t and std::uint8_t likely behave like chars instead of integers Due to an oversight in the C++ specification, most compilers define and treat std::int8_t and std::uint8_t (and the corresponding fast and least fixed-width types) identically to types signed char and unsigned char respectively. WebJan 27, 2014 · On Arduino, char is int8_t but byte is uint8_t. Anyway, in Arduino, byte, uint8_t and unsigned short can be used interchangeably because they are literally the same type.

WebWhilst most types are signed by default (short, int, long long), char is unsigned by default. Because the natural data-size for an ARM processor is 32-bits, it is much more preferable to use int as a variable than short; the processor may actually have to use more instructions to do a calculation on a short than an int!

WebCHAR_BIT is the macro that defines how many bits are in a byte; 8 bits to a byte is only a convention, and it's not always true. In fact, it wasn't until C++17/20 that the spec finally set CHAR_BIT >= 8. So it can be bigger. You can have a 9 bit char, and yet it's still sizeof (char) == 1 by definition. It's still a byte by definition.
