摘要
针对单片机大容量数据采集系统,设计了一种以STM32F107微控制器为核心,以大容量SD卡为存储介质的数据采集系统。简述了开源的FatFS文件系统在STM32处理器上的移植及其底层驱动函数的编写,利用24位∑-Δ模/数转换器实现了高精度数据采集,利用FatFS文件系统实现了采集数据的大容量存储和管理,为数据后续处理和传输提供了便利。
Aiming at the large-capacity data acquisition system, the paper designs a system which takes STM32F107 microcontroller as the core,and adopts SD card as the storage medium. The article outlines the transplant of the open source Fat file system on the STM32 processor and the programming of the low-level driver functions. The system achieves high-precision data acquisition by using the 24-bits ∑-△ ADC,and uses the Fat file system to achieve a large-capacity storage and management for the collected data, which provides a convenience for the subsequent processing and transmission of the data.
