基于 STM32 单片机多路数据采集系统设计The Design Of Multi-channel Data Acquisition System Based On STM32中国地质大学（北京）指导老师王猛、张启升 组员：李金泽 梁迪 张永 .3.31摘要本文是基于 ARM Cortex-M3STM32 系列嵌入式微控制器应用实践，介绍了基于STM32 单片机数据采集硬件设计和软件设计，数据采集系统是模拟域和数字域之间必不可少纽带，它存在含有着很关键作用。本文介绍关键是数据采集系统，而该系统硬件部分重心在于单片机。数据采集和通信控制实行了模块化设计，数据采集和通信控制实行了单片机 STM32 来实现，硬件部分是以单片机为关键，还包含 A/D 模数转换模块，显示模块，和串行接口部分。该系统从机负责数据采集并应答主机命令。输入数据是由现场模拟信号产生器产生，8 路被测电压再经过模数转换器ADC0809 进行模数转换，实现对采集到数据进行模拟量到数字量转换，并将转换后数据传输到上位机，由上位机负责数据接收、处理和显示，并用 LCD 数码显示器来显示所采集结果。软件部分应用 Keil uVision4 经过 C++编写控制软件，对数据采集系统、模数转换系统、数据显示、数据通信等程序进行了设计。关键词：数据采集 89C52单片机 ADC0809 Keil uVision4AbstractThis article is an application of STM32 series embedded ARM controller based on Cortex-M3 and it describes the hardware design and software design of the data on which based on signal-chip microcomputer .The data collection system is the link between the digital domain and analog domain. It has an very important function. The introductive point of this text is a data to collect the system. The hardware of the system focuses on signal-chip microcomputer .Data collection and communication control use modular design. The data collected to control with correspondence to adopt a machine 8051 to carry out. The part of hardware’s core is STM32, is also includes A/D conversion module, display module, and the serial interface. Slave machine is responsible for data acquisition and answering the host machine.8 roads were m...
