摘　　要：介绍了一种用T I公司新一代16位单片机M SP 430系列的M SP 430F 1101设计的数据采集系统。M SP 430系列是T I公司推出的超低功耗混合信号微控制器,这些微控制器可用于电池供电并长期工作的场合。该数据采集系统通过利用M SP 430F 1101内部可用于模拟信号比较功能或单斜率A/D转换功能的片内比较器采集模拟信号,又利用内部具有3个捕获/比较寄存器的16位定时器产生定时间隔,最后将采集到的数据经过模拟串口实现发送。试验证明,采用M SP 430F 1101设计的数据采集系统非常适合于电池供电和便携式应用场合。A kind of data acquisition system which is designed by MSP430F1101 single chip is introduced in this paper. The MSP430F1101 is a member of the TI Company new generation 16 b microcomputer MSP430 family. The MSP430 series is the ultra - low power mixed signal microcontroller and good use of perennial battery power supply occasion. The system acquires analog signal by on-chip comparator for analog signal compare or slope A/D function and times by 16 b timer with three capture/compare registers. It sends data by COM port in the end, It proves that it is available in battery power supply and portable equipment situations.
