全国飞思卡尔智能车大赛中，关于pwm方面的源代码

本设计的由单片机控制的自动加料系统是与料斗式干燥机配套的加料系统。根据加料工艺要求，其工作原理是：先将真空管关闭，启动电机，用低真空气流将塑料树脂粒子送入真空管，电机停转，再将粒子排入料斗，如此循环。-The design of single-chip microcomputer controlled by the automatic feeding system with hopper dryer feed supporting system. Charging process in accordance with the requirements of its working principle is: first vacuum tube to close, start motor, using low vacuum plastic resin particles will flow into the vacuum tube, the electrical switch to stop, and then particles into the hopper, and so the cycle.

C51常用程序库，包含了常用的程序模块和功能，可以直接在设计中参考。-C51 common libraries, which includes the procedures used modules and functions can directly reference in design.

51控制STA013实现MP3音频解码，实现了STA013的初始化、音量调节、静音、音质设置、声道控制。同时包含通过RS232串口控制LCD实现同步显示。代码经过调试，运行通过。

2007年刚推出的语音芯片ISD1760和单片机STC89C58配套的C51源程序，调试通过，包括完整的C语言和头文件-2007 has just launched ISD1760 voice chip and single chip package STC89C58 the C51 source, debugging through, including the complete C language and header files
