本系统以单片机AT89C52为核心,以数模转换器DAC0832实现方波、正弦波、三角波、锯齿波波形的输出，实现信号发生器的简易功能。(This system with single chip microcomputer AT89C52 as the core, with digital to analog converter DAC0832 achieve square wave, sine wave, triangle wave, sawtooth wave form output, realize the simple function of the signal generator.)

说明：  由晶格振动声子态密度计算迪拜温度、比热、振动熵等热力学性质的程序。(the programme for caculation of the debye temprature，specific heat, entropy and so on from the DOS of phonon )

说明：  采用4路红外对管进行循迹，电机控制小车运动。(Four infrared channels are used to track the tube, and the motor controls the motion of the car.)

非常全的103编程资料，以及C语言的103头文件定义代码，非常适合正在开发103通讯规约的朋友(103 very full program information, as well as 103 files define the C language code is very suitable communication protocol being developed 103 friends)

此程序为4*4矩阵键盘，键盘自身不带电源电阻，八个接线，在程序中进行需进行软件拉高拉低以便按键扫描。 应用单片机为MSP430F5529。(4* 4 matrix keyboard without power resistors MSP430F5529)

说明：  osg中的switch开关功能，可以显示场景中想要看到的节点。(osgswitch)
