摘要
基于DSP TMS320F2812和USB主机接口器件SL811HST,遵循标准的USB通讯协议,设计了一种嵌入式温度记录仪。详细介绍了系统的设计方案及各个模块的硬件电路和软件实现。将采集到的温度数据以文件形式存入U盘或SD卡,便于用户分析温度数据。测试表明,该记录仪测量精度高,速度快,解决了恶劣环境下数据采集以及海量存储问题。
Based on digital signal processor TMS320F2812 and USB host-slave interface chip SL811HST,a general embedded temperature; recorder is designed with USB protoeol in this paper.The operation principle,hardware and software implementation of the system are described in detail.The temperature data is saved in the U disk or SD eard in the form of file which can help user to analyze temperature data.The test results show this method solve data eolleetion and mass storage problems under the harsh environment.
