NXP microcontrollers (such as Kinetis and LPC series) feature a module related to keyboard input called KBI (Keyboard Interrupt Module), which implements most of its functions that can also be achieved by microcontrollers from other brands. The difference is that the latter consumes more software or hardware resources (besides the MCU), and to highlight versatility, … Read more
🧠 1. Physical Storage Structure On-Chip Memory IRAM (Instruction RAM) 192KB (ESP32 classic version), with the first 64KB fixed for dual-core CPU cache, and the remaining space used for high-speed execution code (such as interrupt functions). DRAM (Data RAM) 328KB, used for global variables and stack data. About 64KB will be occupied by the protocol … Read more
Are you still troubled by the short connection distance, weak wall penetration, high power consumption, and susceptibility to interference in industrial environments of traditional Bluetooth? The MYF-F20VB01 module, designed to break through these bottlenecks, has arrived! It is built on the Hisilicon BS20V100 platform, supports BLE and SLE, and integrates ultra-low power consumption, industrial-grade anti-static … Read more
👆If you wish to see more often, feel free to star🌟 and bookmark it~ Since the release of the STM32F103 series in 2007, STMicroelectronics’ STM32 series has gone through nearly two decades, and its MCU/MPU series products have long become benchmarks in multiple markets. To date, the STM32 MCU has developed five major categories and … Read more
Today I checked the news and saw that ST has been breached? Then I noticed the new product from GD32. I took a quick look and felt that the Cortex®-M23 was somewhat unfamiliar, so I gathered some information to write about it before going to sleep. GD32C231-MCU.png On June 5, 2025, GigaDevice (stock code 603986), … Read more
