摘要
介绍了一种用TI公司新一代16位单片机MSP430系列的MSP430F169设计的实时数据采集系统。MSP430系列是TI公司推出的超低功耗混合信号微控制器,这些微控制器可用电池供电并长期工作。利用单片机内部自带的12位AD和DMA进行数据的采集和传输,并通过液晶显示模块将采集的数据以波形方式直观地显示。该系统具有硬件电路简单、采集精度较高、界面友好等优点。
A kind of data real- time collecting system which is designed by MSP430F169 single chip is introduced in this paper. The MSP430F169 is a member of the TI Company new generation 16 bit microcomputer MSP430 family. The MSP430 series is the ultra low power mixed single microcontroller and good use of battery power supply occasion. The single chip can collect and transmit the data with its own AD and DMA,and display the data clearly with wave shape by LCI) Module. The system has these merits such as simple hardware,higher precision and friendly interface,so it as value of spread and application.
