51系列单片机读卡程序，本人亲测，适合考勤、门禁。

工程制图是一个非常重要的东东，需要每一个人沉下心来仔细学习-tom is a boy

本模拟I2C软件包包含了I2C操作的底层子程序，使用前要定义好SCL和SDA。在标准8051模式(12 Clock)下,对主频要求是不高于12MHz-The simulation package includes I2C bottom I2C operation subroutine, before the definition of a good use of SCL and SDA. 8051 in standard mode (12 Clock), the requirements for the frequency is higher than 12MHz

KEILC51使用技巧及实战 是一本关于Intel 80C51 以及广大的51 系列单片机的书这本书介绍给读者一些新的技术使你的8051 工程和开发过程变得简单请-KEILC51 skills and the use of combat is on an Intel 80C51 and a vast 51 Microcontroller series of books on this book to give readers some new technology to make your 8051 projects and the development process becomes simple request

嵌入式操作系统SMALL RTOS51 的例程, 运行于UV2运用WAVE的6000进行仿真

步进电机控制程，加减速控制。行走步数控制-Stepper motor control process, acceleration and deceleration control. Control of walking a few steps

The ADC0803 family is a series of three CMOS 8-bit successive approximation A/D converters using a resistive ladder and capacitive array together with an auto-zero comparator. These converters are designed to operate with microprocessor-controlled buses using a minimum of external circuitry. The 3-State output data lines can be connected directly to the data bus.

介绍用单片机实现时钟的程序,可共大家学习,交流.-Introduced with MCU clock procedures, a total of U.S. study, the exchange.

51单片机串口数据包收发程序，能一次收发多个字节，可跟据需要自行修改字节长度，并且具有接收超时判断功能。-51 Single-chip serial data packets to send and receive procedures, can send and receive more than one byte can be modified according to the needs of self-byte length, and have to receive overtime to determine function.
