In the field of embedded system development, real-time operating systems (RTOS) are crucial for ensuring that devices respond to events in a timely manner. With the rapid development of the Internet of Things and edge computing, developers need an efficient RTOS that meets modern demands. DistortOS, as an open-source, object-oriented C++ real-time operating system, promises … Read more
1 Introduction The Hardware Abstraction Layer (HAL) is an interface layer located between the operating system kernel and the hardware circuitry, aimed at abstracting the hardware. It hides the hardware interface details specific to a platform, providing a virtual hardware platform for the operating system, making it hardware-independent and portable across various platforms. The HAL … Read more
1 Introduction to nr_micro_shell During debugging and maintenance, it is often necessary to interact with microcontrollers to retrieve or set certain parameters or execute specific operations. nr_micro_shell is a basic command line tool designed to meet this need for resource-constrained MCUs. Although the finsh command line interaction tool provided in the RT_Thread component is powerful, … Read more

For embedded systems, if there is no RTOS running, the main function main() in program development needs to use some mechanism to keep running happily forever; it has no endpoint. If you want to exit the main function, what happens specifically is determined by the C language compiler used. 1. The Question Raised Today, I … Read more
1. The Concept of “Memory Alignment” Memory alignment, also known as byte alignment, is an attribute of the memory address where a data type can be stored. This attribute is essentially the memory address itself, which must conform to certain specifications. This specification states that the memory address value must be a power of 2. … Read more
As the electronic architecture of vehicles enters an upgrade cycle, various levels of supporting software have become the focus of competition among suppliers. Among them, in the underlying RTOS part, BlackBerry QNX currently occupies a major market share, while companies like Huawei, Zhaoma, Wind River (acquired by Aptiv), and Horizon are also vying for market … Read more
Reprinted from Linux Fan What operating systems are generally used on airplanes? This is the answer many people have been wanting to know. This section is based on an answer from V friends reprinted from Baidu Zhidao: Aerospace software is not mysterious; from a computer architecture perspective, it is not much different from ordinary computer … Read more
