1. Preface In recent years, the Internet of things has developed very rapidly, and various peripheral devices have been connected to the Internet for remote integrated control. For example: intelligent transportation, forest fire prevention, intelligent community, intelligent parking lot, intelligent animal husbandry, intelligent agriculture, ...

In autumn, I memorized a lot of octets of the operating system, but I still lack the experience of hands-on practice. There is no clear understanding of how the operating system works, how user programs run, and how to interact with CPU and other hardware. Therefore, recently, I plan to learn the knowledge of the operating system, and ...

15, Linux thread synchronization 1, Thread synchronization concept Thread synchronization is co synchronization, and each thread runs in a predetermined order Thread synchronization means that when a thread makes a function call, the call will not return until the result is obtained. At the same time, other threads cannot call this fun ...

I suddenly want to open a new pit and write something, which is equivalent to my own understanding. I don't say much about building a development environment and configurati ...

1, The external crystal oscillator failed to start, resulting in abnormal serial port baud rate Model: stm32f407 In the development process, due to the design problems of wiring and conditioning circuit, the external crystal oscillator will fail to start. In stm32, when the external crystal oscillator fails to start, the internal high-spee ...

Functions are organized, reusable snippets of code used to implement a single, or associated function. Function can improve the modularity of application and the reuse rate of code, which is more convenient for the program to realize complex functions 1, Define a function Functions in Python are divided into built-in functions and custom func ...

1. Preface After compiling the minimally configured Fragrant Core (CONFIG=Minimal), you can continue to try out the next two GUI tools according to the readme guidelines. But the goal is not to formally start analyzing code and functionality, but to expect that it will make sense for beginners to experience their own setbacks in this visua ...
