Advantages of ESP32 Before discussing this issue, we first need to outline the advantages of ESP32 compared to STM32. The ESP32 features a dual-core 240MHz processor, built-in WiFi and Bluetooth including low power Bluetooth, while most STM32 chips lack built-in wireless capabilities and rely on external devices for wireless communication, which is the main advantage … Read more

The TM1637 four-digit seven-segment display module is a 4-digit common anode display module (0.36 inches) with a clock point. The driving chip is TM1637, and the driving method is IIC, so only 2 signal lines are needed to control the 4-digit 8-segment display (the brightness of the display can be adjusted in 8 levels). Module … Read more
What is the comparative performance of Arduino and STM32? Many electronics enthusiasts face a dilemma when choosing between Arduino and STM32.

Bit-banding operations may not be used as much now, but in the past, when MCU performance was not very good, bit-banding operations were a common operation among many software engineers. This article mainly discusses the Cortex-M3 core (STM32F1), and I believe many friends have been confused when they first learned about it. 1About Bit-Banding Operations … Read more
