from AVR MCS51 to change, if you are a MCS51 now understand, and indeed want to...

这是一个关于PWM调光的程序，二极管等渐灭和渐亮-This is a program on the PWM dimming, diodes, etc., and getting brighter gradually eliminate

数码管的显示子程序，对于用PROTEUS来仿真的同志，可以尝试的玩一下-Digital tube display subroutine for simulation using PROTEUS to comrades, you can try to play like

很有用的一些从用代码 有keil编译实现的 可以-Useful to have some code from keil compiler can realize

x5045的相关程序，可以在keil c 上运行-X5045 procedures, you can run keil c

一套MSP430单片机完整程序，便于初学者学习-a MSP430 integrity procedures, facilitate learning beginners

///*** *** *** * //一、程序说明： //1, 24LC02器件地址是1010000R/W. //2, 数组写入24LC02采取页写方式. //3, 数组code从24LC02读出时采取自由读方式. //4, 采用4.00M晶体。 //5，采用软件I2C。 //二、硬件连接： //1， SDA------->23 pin.(当然你可以任意选择脚位） //2, SCL------->18 Pin.(当然你可以任意选择脚位） //3， PORTB----->数码管的段输出 //4， RD4，RD5，RC6，RC7------->数码管的位输出(数码管为共阴极） -///*******************// A description of the procedures:// 1, 24LC02 device address is 1010000R/W.// 2, write an array to take 24LC02 page write mode.// 3, the array read out the code from the 24LC02 to take a free read.// 4, using 4.00M crystal.// 5, using software I2C.// Second, the hardware to connect:// 1, SDA-------> 23 pin. (Of course, you can choose to pin)// 2, SCL-------> 18 Pin. (Of course You can choose pin)// 3, PORTB-----> digital tube output segment// 4, RD4, RD5, RC6, RC7-------> digital pipe-bit output (digital tube for a total of cathode)

采用定时器中断的方法，设计一个一天24小时进制的实时时钟；用6个发光二极管分别显示时、分、秒的记时； 能进行整点报时。可以从键盘中预置、修改时钟值。含有硬件设计图-timer interruption using the method to design a band 24 hours a day in real-time clock; With six light-emitting diodes showed the hours, minutes, and seconds to the entry; Can the entire point timekeeping. Which can be preset from the keyboard, the revised value of the clock. Containing the hardware design
