Mainboard - Software - Notation - Types and prefixes
Header file: “xll_stwtypes.h”
In the past used type names like 'word', 'long' or 'dword' are mistakeable. They can have a different meaning dependent to the platform where they are used. E.g. 'word' means 16 bits at a 16-bit controller like the Infineon C167 or a 16/32-bit controller as the Freescale 68k. At a 32-bit controller like the used TriCore TC1796 it would mean 32 bits. There 16 bits are called a 'halfword' instead. That is why STW introduced unambiguous types like 'uint16' to avoid confusions in future.
Recommended unambiguous type definitions and prefixes
| STW type | Prefix | Size | Range (hexadecimal - HEX) | Range (decimal - DEC) | C equivalent |
|---|---|---|---|---|---|
| uint8 | u8_ | 8 bit | 0x00 .. 0xFF | 0 .. 255 | unsigned char |
| sint8 | s8_ | 8 bit | 0x80 .. 0x7F | -128 .. +127 | signed char |
| uint16 | u16_ | 16 bit | 0x0000 .. 0xFFFF | 0 .. 65535 | unsigned short int |
| sint16 | s16_ | 16 bit | 0x8000 .. 0x7FFF | -32768 .. +32767 | signed short int |
| uint32 | u32_ | 32 bit | 0x00000000 .. 0xFFFFFFFF | 0 .. 4294967295 | unsigned long int |
