IoT smart lights

Physical network smart lights can synchronize data to users' mobile terminals in real time through the Internet, and users can also remotely control smart lights through mobile terminals. The smart light mainly consists of 3 parts: 1) GD32E231 as the main control, which can control peripherals; 2) ESP8266 as the Wifi communication module, responsible for transparently transmitting data between the main control and the BcServer server, and realizing data interaction with GD32E231 through the serial port; 3) LED lights, that is, peripherals, are controlled by GD32E231 using GPIO. Smart lights and Android APP use Beecom protocol (referred to as BC protocol) to transmit data to each other through the BcServer server.

BLDC driver based on GD32

A brushless motor may seem like a simple thing, but it can be very complex to drive. As an electronics enthusiast, I just tried it with the spirit of a newborn calf who is not afraid of tigers. It doesn't take long either. So the things I make only have one look, and I hope you won’t criticize them.

AC current measurement system based on STM32 (program, circuit information)

The overall structure of this design is roughly composed of a main control module, a current signal sampling module, a power module and a serial port output module. In this article, the main control chip uses a microcontroller model STM32F103RC, which makes the structure as small as possible while ensuring the current sampling accuracy. It is as simple as possible, avoids complex and changeable circuit layout, is more convenient for PCB board production, and is relatively low-cost. Among them, in the design of the sampling conditioning circuit, a current transformer is used to sample the current signal.
