e2prom通过i2c总线的读写 注释少了点 自己编的 -E2PROM through the i2c bus read and write their own series of Notes少了点

1， SPI_877A,是针对PROBE877A所写。 SPI_877,是针对PROBE877所写。 SPI_77，是针对PROBE77所写。 初次使用使用PICMATE2004或者其简化版精灵版，如果为以上提到的3款型号，并有TPDEM1， 请根据PROBE型号在相应文件夹下打开项目，编译，并运行，具体连线请看各文件夹说明。 2， 其它文件夹项目均针对PROBE877A所建立，如果要使用PROBE877，请修改头文件，并选择PROBE877支持的芯片。 3， 严格禁止将PROBE877与877A混用，否则将造成仿真芯片工作异常。-1, SPI_877A, is written by PROBE877A. SPI_877, is written by PROBE877. SPI_77, is written by PROBE77. First-time use or its PICMATE2004 Wizard version of Starter Edition, if for the above-mentioned models 3 and TPDEM1, please PROBE models in the corresponding folder to open the project, compile, and run, the specific connection see the folder Note. 2, other projects are folders created for PROBE877A, if you want to use PROBE877, please amend the header file, and select PROBE877 support chips. 3, is strictly prohibited PROBE877 and 877A will be a mix, or else the work will result in simulation chips abnormal.

使用89S52设计的电子钟，C51 编写，本例没有使用1302等时钟芯片，但本例完全具有时钟芯片的功能。比如基本的年月日，时分秒和星期功能，而且还有平闰年的天数自动补偿。由于采用的是全软件算法，时钟误差较大，采用高质量晶振可以减少误差。本例重在培养与训练初学者对C51的学习。-89S52 designed using an electronic clock, C51 preparation, in this case did not use 1302 clock chip, etc., but in this case complete with a clock chip functions. For example the basic date, time, and every second week of features, but also the number of days flat leap automatic compensation. As a result of the full software algorithms, the clock error of greater use of high-quality crystal can reduce the error. In this case focuses on training and training for beginners to learn on the C51.

代码说明了一个ps2口驱动和编程方法。主要是鼠标,当鼠标产生中断时，主板上的蜂鸣器和运行灯都有反映。移动鼠标或点击鼠标的左右键，发现主板有反映。注意，因为程序并没有驱动滚轮，所以鼠标滚轮不能产生中断。--PS2 port driver and programming method. When mouse generates an interruption, alarm and light will have response. You could move mouse or hit the left or right button, and observe the reaction of motherboard.
