单片机

串行IIc总线型EEPROM24c02的读写汇编源程序，并由按键控制读写操作。-Serial Bus type IIc EEPROM24c02 compilation of source code to read and write, and write control buttons.

提供了LED点阵显示的Proteus仿真电路，和汇编代码。-LED dot matrix display provides a simulation circuit of the Proteus, and assembly code.

单片机最小系统，两位LED数码管由串口输出接两个164驱动，Lout,Rout为左右声道输出，SET， ALT0， ALT1为三个按键，也可自己在开始的I/O定义改成你想用的I/O口；12M晶振，若用89C51则只可装下约14首歌曲，用89C52则可装下近40曲-The smallest single-chip system, the two LED digital tube by the serial output driver 164 then two, Lout, Rout output for the left and right channels, SET, ALT0, ALT1 three buttons can also be their own at the beginning of the I/O definition change you want to use the I/O port 12M crystal, if one uses a 89C51 only loaded about 14 songs can be loaded with 89C52 under near 40

对于有想自己DIY mp3的同志们要注意了，参考参考别人的设计思想也是有必要的，希望这张原理图对大家有帮助！-for a DIY mp3 to their comrades to attention, others refer to the reference design is also necessary, I hope this diagram to help you!

本程序已经调试通过，使用I2C来从外部时钟芯片中读取并写入时间。文档包含i2c的驱动程序、时钟芯片的读与写、以及使用定时器中断产生脉冲来模拟gps对时。-This procedure has been debugging through the use of I2C chip from the external clock time to read and write. Document contains the i2c driver, the clock read and write chip, and the use of the timer interrupt to simulate the pulse generated when the gps on.
