M SP430F1101单片机在数据采集中的应用
Application of MSP430F1101 Single Chip in Data Acquisition
【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。
【Abstract】 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 ultralow power mixed signal microcontroller and good use of perennial battery power supply occasion.The system acquires analog signal by onchip 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.
