常用组件数据库包（PCB）..................

基于Freescale公司的8位单片机MC68HC908GP32，提供一些简单的实验仿真程序，以便初学者学习-Based on Freescale

430中149单片机的ADC使用源码，测试通过-430code

必用的C程序,单片机实现滤波器的方法-Procedures must be used in C, single-chip filter methods realize

PWM温度控制的，将风扇等制冷设备连接到单片机的指定IO口上即可实现设备输出功率的人工控制。-PWM temperature control, refrigeration equipment, such as the fan is connected to MCU IO port on the specified equipment to achieve the artificial control of output power.

该头文件配合key.c，在main函数中调用key.c，都文件中添加key.h，使软件更清晰，一目了然-The header file with key.c, in the main function call key.c, all files add key.h, so that software is more clear at a glance

Used to display a hexadecimal value in 7 segment LED display using an interrupt in PORTB upper 4 bits.

一个时时单片机发送数据测试代码-a microcontroller always send data test code

非常好的介绍MCS-51单片机以及汇编指令编程的文挡！可以打好扎实的基础。-Very good description as well as the MCS-51 microcontroller programming text block assembly instructions! You can lay a solid foundation.

单片机控制的语音智能小车，能感应人的命令做出动作。十分好的程序！-Smart single-chip voice-controlled car, the order can be induced to move. Very good program!

AD9850 DDS控制子程序 经常做其他的单片机实验，还没做过DDS的实验。最近打算写个程序试验一下。 -AD9850 DDS control subroutine Singlechip often to do other experiments, not yet done DDS experiment. The recent plan to write a program to test.
