单片机读写优盘，实现了单片机读写优盘的功能 还有FAT32文件系统 的实现...

矿工定位系统,包括单片机原理图,PCB,KEILC51原代码,带瓦斯检测功能,成熟产品正在使用中-Miners positioning systems, including single-chip schematic, PCB, KEILC51 the original code, with gas detection, mature product is in use

《模拟I2C总线多主通信的通用软件包》,支持多主竞争，比如有多个单片机和I2C器件同时工作。- Simulation of multi-master I2C bus communications generic package to support multi-master competition, for example, has a number of SCM and I2C devices work at the same time.

用C51中I/O口摸拟串口-simulate serial port with I/O port in language of C51

利用HD66421实现灰度字符显示，keilC51编译环境-HD66421 realize the use of gray-scale character show, keilC51 compiler environment

Fujitsu MB89P475的应用实例-Fujitsu UART examples of the application

IO口模拟串口发送，可用于双串口，可被其他程序调用 void rs2_send_byte(uchar cByte) 向串口发送一个字节-Send serial port analog IO, can be used for dual-serial port, other procedures can be called void rs2_send_byte (uchar cByte) sends a byte to the serial port

AVR单片机浮点数、串口波特率、定时器参数计算器，很不错的小软件！-AVR microcontroller floating-point, serial baud rate, timer parameter calculators, a very nice small piece of software!

16进制转压缩型BCD码的C语言实现-16 hexadecimal to BCD code compression realize the C language

atmega16测电压源码，适合AVR单片机的初学者-atmega16 measuring voltage source, suitable for beginners AVR Microcontroller

普通IO口模拟RS232串口 占用定时器0中断 在TH0,TL0中设置波特率的大小 注意不要开定时器0的中断，这里用的是查询方式-ordinary RS232 serial I simulated occupancy Timer 0 interrupt the switching, TL0 set baud rate to the size not to open the Timer 0 interrupt here with the inquiry
