originated from a project that started around 1985. POSIX is an easy-to-remember name proposed by Richard Stoman at IEEE's request. It is basically the abbreviation of Portable Operating System Interface (the Interface that can be transplanted to the Operating System), and X indicates its inheritance of Unix APIs.
The purpose is to improve the portability of applications between various Unix operating system environments. That is, any POSIX-compliant application can be re-compiled and run on an

Top 10 microprocessors
As a "old bird" who has been engaged in the electronic industry and is full of dust and sweat
The MCU has three digits, right. To put it bluntly, the microprocessor is a machine that handles things, just like a human
The brain is also the publishing center for all behavior commands. Throughout the electronics industry, the development of microprocessor is particularly rapid, coupled with power-on
Sub-products are constantly upda
When we are immersed in the 4G network of high-speed, ridicule 4G network charges, the next generation of mobile communications network--5g has been published.
5G Network as the next generation of mobile communications network, the highest theoretical transmission speed of dozens of GB per second, which is faster than the current 4G network transmission speed hundreds of times times, the entire Super High-definition film can be downloaded within 1 seconds.

To some extent, this article provides our development direction and tips. here specially reprinted. Original: http://blog.csdn.net/coolbacon/article/details/8521841 recently my work is too busy. My friends around me asked me how to learn embedded technologies and make healthy development in this industry. I have never been able to make a system answer. I want to write an article to answer this question thoroughly.
Embedded. This is a term. In my opinion, the embedded system is a computer system

But now, Zhongguancun has not become "Silicon Valley", and China's electronics industry is still struggling after the storm. So people finally calmed down from their passion and began to rethink: Where is ZhongGua

In early Wireless LAN, clients embedded with Wi-Fi usually refer to bar code scanners, point-of-sale terminals, voice IP handheld devices, or other special-purpose devices. Access control is generally loose. The methods used include MAC addresses and Protocol filters, as well as hiding SSID and static WEP passwo
Yesterday, Ti made a shock to the electronics industry, announced the latest release of Sitara am335x arm Cortex-A8 microprocessor, the bulk price of only 5 dollars, at the same time, it also launched an easy-to-use open-source hardware platform and a free software development kit at an ultra-low price of $89. Both prices can be said to have broken the current industry's gaming rules.
