基于MinGUI和SD卡FAT32文件系统的数据采集显示终端

Data Acquisition and Display Terminal Based on MinGUI and SD Card FAT32 File System

详细介绍了一种基于MinGUI和SD卡FAT32文件系统的数据采集显示终端的设计与实现。采用SEP4020作为微处理器,配有AD数据采集模块、TFT液晶屏图形界面显示模块和SD卡数据存储/读写模块等,并利用μC/OS-II嵌入式操作系统管理任务之间的切换与通信。该系统实现了对模拟信号和数字信号的采集,在显示终端上进行实时显示和触摸屏操作控制,并将数据存储在SD卡中供上位机做进一步数据分析等功能。

The introduction of this paper is based on MinGui and SD card FAT32 file system for data acquisition and display terminal design and implementation. Using SEP4020 as the microprocessor, with AD data acquisition module, TFT LCD screen Graphical display module and SD card data storage / read and write module ect, and using μC/OS-Ⅱ embedded operating system for managing switching and communication between tasks. The system implements the acquisition of analog and digital signals, displaying in real-time on the terminal display, operatoring control of touch screen, and storing the data on the SD card for the PC for further data analysis and other functions.
