The value generated by data far exceeds the value of global goods trade —— McKinsey, “Digital Globalization” (2016) There are billions of connected IoT devices globally. These devices span multiple industries, whether they are security cameras, health monitoring devices, or simple office printers, they possess transformative power. However, with the explosive growth of connected technology, … Read more
In the development of ESP32 projects, time management is crucial. It allows you to precisely control program execution, complete scheduled tasks, log data, and even implement complex timing functions. The ESP32Time library has emerged to provide a series of convenient APIs, enabling developers to easily retrieve and set the time of the ESP32’s internal RTC, … Read more

1. Interrupt Priority <span>Cortex-M</span> series cores (such as <span>M3/M4/M7</span>) use the <span>NVIC</span> (Nested Vectored Interrupt Controller) to support interrupt nesting and priority management. It employs a grouping mechanism that divides interrupt priority into two parts: Preemption Priority: Determines whether the current interrupt can interrupt other interrupts. Subpriority: Determines the response order when preemption priorities are … 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
