As the demand for battery life in terminal devices increases, low-power MCUs are becoming more widely used. So, what is a low-power MCU? Which categories have a strong demand for low-power MCUs? What trends are emerging in the development of low-power MCUs? Wide Application Scenarios “Typically, low-power MCUs utilize different design methods and processes compared … Read more
If there were no MCU, we would not deserve to be called “modern people”. MCU is not the Marvel Cinematic Universe. As a necessity for modern life, MCU (Microcontroller Unit, 微控制单元, also known as single-chip microcontroller) has long been integrated into human production and life, and is ubiquitous. Air conditioners, remote controls, smart chargers… basically … Read more
Anyone working in information technology must have heard of embedded systems and microcontrollers. It is well known that these two terms are closely related to hardware systems. However, if you ask what embedded systems are and what microcontrollers are, and what the differences between them are, I believe most people cannot explain clearly. Today, I … Read more
Since STMicroelectronics (ST) launched the first STM32 Cortex-M core MCU in 2007, over 16 years, the cumulative shipment of the STM32 series has exceeded 11 billion units, including mainstream, ultra-low power, high-performance, wireless MCUs, and five major series of MPUs. ST’s ranking in the global general-purpose MCU market has jumped from 3rd place in 2017 … Read more
STM32: Released by STMicroelectronics on June 11, 2007, it is a 32-bit microcontroller. GD32: Released by GigaDevice in 2013, it closely imitates STM32 in chip development, configuration, and naming. In fact, the GPIO pins are pin-to-pin compatible with STM32, meaning you can use GD32 without altering the PCB. Sometimes, you can run STM32 source code … Read more
Click the blue text above: IoT Inn Serial communication plays a very important role in embedded development. It is often used to debug systems, print necessary debugging information, and help us analyze and locate problems. Many common peripherals also support serial protocols, such as WIFI modules, Bluetooth modules, 4G modules, fingerprint modules, PM2.5 sensors, formaldehyde … Read more
