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)

电子称重的实现首先是通过压力传感器采集到被测物体的重量并将其转换成电压信号。输出电压信号通常很小，需要通过前级信号处理电路进行准确的线性放大。放大后的模拟电压信号经AD转换进入主控单片机中，再将结果显示在人机界面。(The realization of electronic weighing is firstly to collect the weight of the measured object through a pressure sensor and convert it into a voltage signal. The output voltage signal is usually very small, which requires accurate linear amplification through the front signal processing circuit. The amplified analog voltage signal is converted into the main MCU by AD, and the results are displayed in the man-machine interface.)
