) it is probably beter to convert this to the stdint.h types, which will be naturally portable across platforms.// Type definitions for os-utils 0.0 // Project: // Definitions by: Nasreddine Bac Ali // Definitions: type Platform = | 'aix' | 'android' | 'darwin' | 'freebsd' | 'linux' | 'openbsd' | 'sunos' | 'win32' | 'cygwin' /** * returns platform. In addition, it is quite common that programmers will have defined their own types (UINT8, s8, BYTE, WORD.

If this size has been relied on, some of the code may need updating to make it more portable. For example, int may have been represented as 16-bits. In code ported from other platforms, especially 8-bit or 16-bit platforms, the data types may have had different sizes. Whilst most types are signed by default (short, int, long long), char is unsigned by default.īecause 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! The ARMv7-M architecture used in mbed microcontrollers is a 32-bit architecture, so standard C pointers are 32-bits.

The appropriate stdint.h types for storing and working with data explicitly at the bit level.

uint32_t for bit manipulations, especially on 32-bit registers.

float for general measurable things (seconds, distance, temperature).

Different operating systems run on different types of hardware and are.

int for most variables and 'countable' things (for loop counts, variables, events) Most computers and smartphones come with an operating system installed on them.
