Router Flashing This section refers to the relevant tutorials from various manufacturers, but it is said that there is a firmware called breed, which seems to make the router less likely to become bricked after flashing! Changing the Default Mirror Source of the Router and Preparation Work Connect to the router using SSH, by default … Read more
For general-purpose MCU chips, the CPU operating frequency ranges from 100 to 300 MHz, while the frequency of typical crystals (xtals) is usually in the tens of MHz range. Therefore, MCUs typically use a PLL module to multiply the frequency to the hundreds of MHz range.Similarly, taking the STM32F10xxx series as an example, let’s examine … Read more
According to a report by Electronic Enthusiasts (Author: Wu Zipeng), humanoid robots are gradually moving from the conceptual stage to large-scale implementation, leading to a significant increase in demand for chips. Whether as the “brain” and “cerebellum” core computing modules, or in perception and control systems, chips are the key foundation for realizing these system … Read more
Click 👆👆👆 the blue text Follow “Passion Embedded” In embedded development, especially in the development of microcontrollers like STM32, the <span>volatile</span> keyword is a very important concept. 1. Concept of the volatile Keyword <span>volatile</span> is a type modifier in C/C++ that tells the compiler: The variable may be modified unexpectedly (e.g., by hardware, interrupts, or … Read more

Today, let’s discuss a seemingly simple yet powerful technology that can solve complex problems—the microcontroller interrupt system.In automated production lines, it is often necessary to respond in real-time to multiple sensor signals. How can a small microcontroller accomplish this task? The interrupt system acts as the invisible “master scheduler”. What is an Interrupt System? Imagine … Read more
