基于以 STM32F0单片机为核心的多功能数据采集板，可以采集8路模拟量，并提供8路开关量输入和8路开关量输出，采集板通过串口 RS-232C 将采集的数据传给上位机。本文首先介绍了 STM32F0处理器的特点，然后介绍了数据采集板的硬件原理，并对硬件设计方面的难点做了详细分析，接着介绍了系统所使用的串口通信协议，最后根据实际应用效果对该数据采集板的应用前景做了分析和展望。% This paper introduces a kind of multifunctional data acquisition board which uses STM32F0 microcontroller as the core. This acquisition board can collect 8 analog signals, 8 input and output digital signals. The board transmits the acquired data to the upper computer by the serial communication of RS-232C. First, this paper introduces the characte-ristics of the STM32F0 processor, and then introduces the hardware principle of the data acquisition boards, analyses the difficulties of hardware design, and introduces the serial communication agreement used by the system. According to the application effect of the data acquisition boards, the paper analyses and looks forward to the application prospect.
