WebMay 5, 2024 · marco_c: Just using int causes a huge number of issues when you move from one architecture to another, as the size of int is usually defined as the 'natural' size for the architecture. This makes it 8 bits for 8 bit architectures, 16 for 16, etc. The C standard has required the minimum size of an int be 16 bits for many decades.

Arduino: Difference in “Byte” VS “uint8_t” VS “unsigned char”

WebFor example, casting the 16-bit integer 1000 to uint8 with typecast returns the full 16 bits in two 8-bit segments (3 and 232), thus keeping the original value (3*256 + 232 = 1000). The cast function, on the other hand, truncates the input value to 255. The format of typecast output can differ depending on the system you use.

Writers of embedded software often define these types, because systems can sometimes define int to be 8 bits, 16 bits or 32 bits long. The issue doesn’t arise in C# or Java, because the size of all the basic types is defined by the language.

WebThe shift and mask operations are defined in terms of logical bits. & 0xF, for example, will give you the four least significant bits. Edit: this assumes you’re operating on actual integer types. If you take an integer and cast its address to a uint8_t* and manually step through the bytes you’re on your own.
