Currently, most industrial control systems are embedded systems (a few simple systems use bare metal development directly). An “embedded system” refers to a computer system with specific functions embedded within specific hardware. Embedded systems generally consist of a real-time operating system (RTOS) + application software (a PLC itself is also an embedded system). Common real-time … Read more
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
Abstract: To address the challenges of high difficulty and long development cycles in wireless sensor network application development, this paper analyzes the reasons behind these issues and the current state of wireless sensor network application development technologies. Following the principles of software engineering and component design, a four-layer architecture development platform model is proposed. Based … Read more
