Most people start learning about microcontrollers with the most basic 8-bit MCUs. Generally, the three most common series of 8-bit microcontrollers are: the 51 series, AVR series, and PIC series.Recently, there was a discussion in a group about a question: Is it meaningful to run RTOS on a 51 microcontroller? Regarding this question, everyone has … Read more
Transitioning from bare-metal (front-back architecture) software development to using a Real-Time Operating System (RTOS) can be a challenging task. However, there are many advantages to using an RTOS, such as simplifying application integration and supporting task preemption scheduling. This becomes meaningful when developers use complex 32-bit microcontrollers and have sufficient Flash and RAM space. Many … Read more
The rapid development of the Internet of Things (IoT) has exceeded the imagination of almost everyone, with thousands of devices connecting to the network every day. In the face of such enormous market demand, traditional technologies have long been overwhelmed, while the new generation of digital signal processing (DSP) requires higher computational power and lower … Read more
👨💻 Have you ever doubted life while debugging on your embedded programming journey? Today, let’s understand what the so-called “Real-Time Operating System” (RTOS) really is in the most straightforward and humorous way possible! By the end, you’ll be able to boast: “I am an RTOS veteran!” 🚀 🧠 What is RTOS? Don’t be afraid, it’s … Read more

In the previous issue, we discussed the tutorial on setting up PPPoE dialing in OpenWRT. In bridge mode with the optical modem, if PPPoE dialing is not configured, OpenWRT cannot access the internet properly. Tutorial on setting up PPPoE dialing in OpenWRT However, many newly installed broadband connections are set to router mode by the … Read more
<span><span>ubus</span></span> is designed with a concept similar to <span><span>d-bus</span></span> in Linux desktop systems, providing system-level bus functionality. However, compared to <span><span>d-bus</span></span>, it reduces memory usage, making it suitable for the extreme operating environments of low-performance CPUs and low memory in embedded systems. The core component is the <span><span>ubusd</span></span> daemon, which provides an interface for other … Read more
Since many people became familiar with OpenWrt relatively late, there is a common misconception that OpenWrt is synonymous with bypassing restrictions or with bypass routers.However, as a long-time user for over a decade, I have always relied on OpenWrt as my sole router at home.Today, we will share a feature that typically only appears in … Read more
01 Question Many students have been struggling with:Should I learn microcontrollers or embedded systems? Some say that microcontrollers are also embedded systems; is that correct? Is embedded just Linux? Today, let’s discuss this issue. 02 What is a Microcontroller The essence of a microcontroller is a type of computer. So what is a computer?A computer … Read more
ID: Technology Makes Dreams GreaterCompiled by: Li Xiaoyao The main function of a microcontroller is to control peripheral devices and achieve certain communication and data processing.However, in certain specific situations, mathematical operations are inevitably required, even though microcontrollers are not adept at implementing algorithms and performing complex calculations.This article mainly introduces how to implement digital … Read more
