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)

说明：  PT100测温AD显示 用ADC0809实现，内有Keil C 源文件，仿真通过的Proteus电路原理图(DSN)(Ad display of Pt100 temperature measurement is realized by ADC0809, with keil c source file inside, and Proteus circuit schematic diagram (DSN) through simulation)

单片机数码管测试程序（非常不错的单片机学习程序）(Single chip digital test program (very good))

c8051f的tcpip源程序,新一代功能比较齐全的c8051f020单片机的串行通信c程序,通用的c8051系列tcpip源程序，同时包括了ucos的移植。 (c8051f the tcpip source, a new generation of relatively complete functional C8051F020 MCU serial communication c procedures, C8051 Series tcpip common source, at the same time includes uCOS transplant.)

说明：  81 level inverter which uses embedded function block and has the THD around 1 percentddcdc
