Abstract: In the power system, it is very important to detect the current magnitude of the system in real-time. A device for real-time detection of current magnitude in circuits has been designed based on the STM32F103 chip. The measured current is displayed on an LCD screen for easy observation. Additionally, these real-time data are stored on an SD card device for recording the data. The device incorporates the FreeRTOS real-time operating system, enabling more rational and efficient utilization of CPU resources. This simplifies the design of application software, shortens system development time, and better ensures the real-time performance and reliability of the system.
Key words: STM32F103 chip; current detection system; FreeRTOS real-time operating system; data acquisition; current sensor
