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.

• 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。
