x25045的编程应用（51汇编格式），它具有512字节的EPROM，看门狗，复位信号等，是MCU不错的外围芯片...

本程序主要通过外部中断INT0及3.3端口读取PS2键盘值并通过LCD1602显示，键扫描码的解码通过数组方式解码，程序的解码功能主要针对数字及大小写字母和常用标点符号 硬件描述：PS2键盘的时钟线（clk）接89S51的INT0（P3.2）,数据线data接（P3.3） LCD的控制端口分别为： RS = P2^7，RW = P2^6，EP = P2^5，数据端口为P0，液晶显示偏压VL必须接 -This procedure mainly through external interrupt INT0 and 3.3 read PS2 keyboard port value through LCD1602 display, key scan code decoder way through an array of decoding, the procedure for decoding function of the major figures and upper and lower case letters and punctuation marks commonly used hardware description: PS2 keyboard clock line (clk) then 89S51 the INT0 (P3.2), data lines data access (P3.3) LCD control port, respectively: RS = P2 ^ 7, RW = P2 ^ 6, EP = P2 ^ 5, data ports for the P0, LCD bias VL must be received

一个单片机上的sd卡驱动程序，支持fat32，fat16等文件系统，很有参考价值。-A microcontroller on the sd card driver and support fat32, fat16 file system, etc., of great reference value.

44B0＋SL811，学习USB编程的好资料，强烈推荐-44B0+ SL811, learning programming USB good information, strongly recommended

对于没有i2c接口的单片机来说，要用标准i2c器件通讯来说只能通过软件模拟了 本程序提供几个最高效的函数实现其功能，新方法，更高效-For there is no single-chip interface for i2c, i2c devices use standard communications software simulation run only through the procedures provided by several of the most efficient function to achieve its function, new methods, more efficient
