TDC-GP22编程开发及应用实例，适用于超声波时间测量，精度高(TDC-GP22 programming development)

本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)
