PADS9.5实战攻略与高速PCB设计

正弦信号发生程序。使用声卡产生正弦信号输出，可以用来调音！(Sinusoidal signal procedures. Sinusoidal signal generated using the sound card output, can be used to tuning!)

51和迪文串口屏通信C语言源码，温度采集显示，可以进行移植，很友好，很详细，附带的例程帮助很大(51 and Devon serial port communication C language source code, temperature acquisition display, you can transplant, very friendly, very detailed, with the help of a large routine.)

PIC16F886控制红外线程序，希望对大家有帮助。(PIC16F886 to control IR program, we hope to help. )

说明：  非编码键盘是利用MCS—51单片机内部的定时/计数器、中断系统、以及外围的按键和LED数码管显示等部件，设计一个单片机非编码矩阵键盘。并能通过按键实现显示0、1、2、3、4、5、6、7、8、9、A、B、C、D、E、F。(The keyboard is used non-coding MCS-51 microcontroller internal timer/counter, interrupt system and the external buttons and LED digital display and other components, to design a single chip non-coding matrix keyboard. And pass the key to achieve display 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F.)

说明：  0.我使用的是F103VET6，但软件IIC原理都是一样的，改引脚配置后可方便移植 1.连接引脚前，可以只连接VCC和GND查看模块当前地址：模块上的LED指示灯会渐亮，然后就是快闪(1)和慢闪(0)，将值记录下来，用计算器转换一下就是当前的地址值了(0. I use F103VET6, but the principle of software IIC is the same, pin configuration can be easily transplanted. 1. Before connecting pins, you can only connect VCC and GND to view the current address of the module: the LED light on the module will gradually light up, then flash (1) and slow flash (0), record the value, and convert it with a calculator to the current address value.)

LCD的自动调整源代码，经过验证很实用，可以调整，LCD的图像(Automatic adjustment of LCD source code, proven very useful)

sketch_dec12a是arduino文件 读到上位机输出的字符串输出SD卡里面的语音信息。 sketch_dec12a是arduino文件 读到上位机输出的字符串输出SD卡里面的语音信息。(Sketch_dec12a is a string read from Arduino file to output from PC and output voice information in SD card.)

时钟芯片CW1288的驱动程序，适合外挂时钟的系统(CW1288 clock chip driver for external clock system)

strus开发 短租网,一个小项目，功能不是太完整，但是基本差不多了(a project of struts a project of struts a project of struts a project of struts a project of struts a project of struts)

说明：  一个PS2键盘单片机, 使用Philips的接口+8051,写的不错,非常值得学习.(a PS2 keyboard microcontroller, the use of the interface, Philips 8051, was a good, very worth learning.)
