In embedded software development, it is very important to correctly understand the use of stack. In embedded software development without RTOS, the main stack overflow is an easy to ignore error. In RTOS multi task embedded software development, in addition to the main stack, it is also necessary to consider the process stack, and different tas ...

Serial communication of Python Serial communication is a necessary skill for embedded engineers. If you can write a simple host computer, you will get a lot of points. This series is a record of relevant work. After all, Python is not often used and always forgets a lot of things. It's too much trouble to learn it again when you use it. After ...

brief introduction From the perspective of Linux architecture, the kernel system has regarded the driver as an independent sub module. Therefore, the driver module can load (insmod) and unload (remmod) when the kernel system is running. From a functional point of view, the driver module undertakes the function of mapping system function c ...

Recently, I read the book "programming pearls", which focuses on the explanation of engineering treatment, which is well written. The most impressive example is the Brooklyn Bridge. Before the 1940s, many suspension bridges broke due to storms. To do the correct mathematical modeling and engineering calculation of this aerodynamic ris ...

1, Fundamentals of interruption 1. What is interruption Interrupt means that the CPU needs to stop the execution of the current program, turn to deal with emergencies, and return to the original program after processing. 2. Hardware interrupt and software interrupt Hardware interrupt generally refers to the interrupt request sent by the ...

1 embedded C language summary Grammatically speaking, C language is not complex, but it is not easy to write high-quality and reliable embedded C programs. It is not only necessary to be familiar with hardware characteristics and defects, but also need to have a certain understanding of compilation principle and computer technology knowledge ...
