Click the above blue text to follow us Real-time systems are crucial in embedded applications, with the core focus on ensuring tasks are completed within specified time frames. Based on the strictness of deadline adherence, real-time systems are classified into hard real-time and soft real-time. Hard real-time systems require tasks to meet deadlines 100% of … Read more
As an embedded developer, do you have a love-hate relationship with bare-metal programming? Are you overwhelmed by interrupts and questioning your life while writing state machines? Let’s get to know QP/C: a lightweight asynchronous event framework that transforms MCUs into “thinking” entities, allowing you to elegantly manage complex logic and say goodbye to “interrupt hell”! … Read more
With the widespread application of embedded systems in industries such as aerospace, automotive, and industrial automation, developers are increasingly demanding high-performance real-time operating systems (RTOS) and modern graphical user interfaces (GUIs).

Let’s illustrate this issue with a specific example. How does a typical task system handle information in embedded systems? The process looks like this: • Retrieve new data • Filter/process data • Output data Pretty straightforward, right? We know that for real-time embedded system design, the main goal is determinism and minimizing jitter. The three … Read more
Today, we will discuss interrupt handling in ARM Cortex-M. In embedded systems, interrupts are the core mechanism for achieving real-time responses. Imagine if there were no interrupts: • When a button is pressed, the system might be busy with other tasks and miss the response. • Incoming communication data might be lost due to untimely … Read more
When it comes to embedded real-time operating systems (RTOS), names like FreeRTOS and uC/OS may come to mind. However, many may not be aware of the domestic embedded operating systems available. Below, I will introduce several mainstream domestic embedded operating systems, which are also embracing the development of the Internet of Things (IoT) and transforming … Read more
