| 摘 要： | 根据微弱模拟信号的检测需要,利用AD7706具有低功耗、高精度A/D转换的特点,以MSP430F149为控制器,设计了一种多路信号采集系统,编制了A/D转换以及MSP430F149与PC机之间的串行通信软件,实现了采集到的数据能在PC机上显示、存储、绘制曲线,同时PC机能给单片机发送控制命令等功能.实践表明该系统能可靠运行.

| Abstract: | In order to detect little analog signals,AD7706 characteristics of lower power and high ADC conversion resolution are considered and a multi-channel signal acquisition system is designed using MSP430F149 as controller.The ADC conversion and serial communication between MSP430F149 with PC are programmed.The functions are implemented that the acquired data can be stored,displayed,plotted the curve and command can be sent by PC at the same time.The system can run reliably in practice. |
