手持测振测温仪在机械故障诊断中发挥着重要作用,其中的存储系统是该设备的重要组成部分。本文简要介绍NAND Flash与F2812的接口电路,详细说明Flash驱动设计,解决Flash在连续写操作造成数据丢失问题。Flash存储与读写速率均满足本手持仪的要求。
Storage system is an important part in a portable vibration and temperature measurer, which plays a significant role in machine fault diagnosis. This paper briefly introduces the interface circuit between NAND Flash and F2812 and explains the Flash driver design in detail, which solves the data loss during Flash continuous write operation. Both the Flash storage, write and re- trieve data rate meet this measurer' s requirements.
