WebFeb 1, 2012 · As it happens, the problem is a bit worse than non-specified behavior. Linus suggested running a test with a structure like: . struct example { volatile int a; int b:1; }; In this case, if an assignment to b causes a write to a, the behavior is clearly buggy: the volatile keyword makes it explicit that a may be accessed from elsewhere.

Webuctypes – access binary data in a structured way¶. This module implements “foreign data interface” for MicroPython. The idea behind it is similar to CPython’s ctypes modules, but the actual API is different, streamlined and optimized for small size.

This would create holes in the data structure and make it impossible in some cases to talk to h/w registers using bitfields.

A bit field is a data structure that consists of one or more adjacent bits which have been allocated for specific purposes, so that any single bit or group of bits within the structure can be set or inspected. A bit field is most commonly used to represent integral types of known, fixed bit-width, such as single … See more Bit fields can be used to reduce memory consumption when a program requires a number of integer variables which always will have low values.
