基于F2812平台采集存储与回显系统

摘要

介绍了基于TMS320F2812芯片控制信号采集、存储与回显系统,重点讨论整个系统实现软件流程及各功能模块关键技术.主要有CAP单元测频、FLASH数据存储与D/A数模转换.实验测试数据表明:波形采集存储与回显功能完全实现.测频精度高、采样数据写FLASH快速可靠,D/A转换回显波形与原始输入波形吻合度高.%A system of wave sampling storage and display based on TMS320F2812 was proposed. Focused on software flow chart,related modules' key technology such as A/D,frequency measurement,FLASH storage and D/A were performed. Experiments indicate the function of sampling storage and display are realized. High measuring frequency precision, fast speed writing FLASH and reliability meet operation requirement for wave recovery through D/A.
