为了实现数据信息方便快捷传输,基于MSP430单片机的多通道作物蒸发蒸腾量测定仪,将U盘作为存储介质,实现了单片机与U盘的直接通讯。U盘模块通过SPI总线与MSP430F169进行数据通讯,方法简单、易于操作,克服了数据采集器与计算机数据传输对计算机环境的依赖性,对于野外农林业数据信息的采集具有重要意义。
In order to realize data information transmission expediently,U disk is used for storage media of multi-channel and low-power evapotranspiration tester of crop which based on MSP430 MCU and realized the microcontroller and U dish communication directly.The data transmission will become simple and easy to operate.This design reduces the dependence of data transmission between U disk module and MSP430F169 by SPI bus on the computer system and makes the operation easy and simple.It has significant means especially to those plants which grow up in forest and rural areas.
