The so-called bare-metal programming here refers to the "programming of hardware systems without OS support", while the actual programming requires an environment in which the programming and compiling environment is called "host" and the final program runs on the "target" (cross-compiling). and the OS environment programming means that the final running program is running in an environment with operating s

The OS module in the python standard library contains common operating system functions. If you want yourProgramThis module is especially important if it has nothing to do with the platform. That is, it allows a program to run in Linux and Windows without any changes or any problems.
The following lists some useful parts in the OS module. Most of them are simple and clear.
compiler processes other. c files, xxx_global is not defined, and xxx_ext is defined as extern, so that you can call external global variables. To illustrate this concept, see uC/OS _ii.h, which includes the following definitions: # ifdef OS _globals
# Define OS _ext
# Else
# Define OS _ext extern
# Endif
8.2 OS. path -- common path name Operation (1)
OS. path. isabs (path)
If the path parameter is an absolute path, True is returned; otherwise, False is returned.
Example:
# Python3.4
Fromos. pathimport *
Pathstr = 'f: \ temp \ py \ cal_1.py'
R = isabs (pathstr)
Print (r)
The output is as follows:
True

I. Introduction
Symbian OS is an open and robust embedded operating system developed by Symbian. Symbian OS is a new-generation mobile system platform for wireless handheld devices in the future. Its goal is to develop Symbian OS into an industry standard for mobile phones in the future. Therefore, it provides convenient conditions and strong support for applicat
Learn about common Mac OS X shortcuts. The shortcut key is used to call Mac OS X by pressing the combination key on the keyboard.
To use shortcuts or key combinations, you can press the modifier key and character key at the same time.
For example, if you press the Command key (the key marked with a symbol) and the "c" Key simultaneously, any selected content (text, graphics, etc.) is copied to the cart. Thi

In the multi-tasking process, the operating system should solve two problems: one is that each task should have a mutual exclusion , that is, for a share of a shared resource , if a task is in use, other tasks can wait until the task releases the resource. Wait for one of the tasks to use it, second, the relevant tasks in order to be executed, a task to wait for its partners to notify or establish a condition to continue to execute, or only wait.
