通过51单片机串行转并行，扩展IO口，实现四个步进电动机的控制。(By 51 microcontroller serial to parallel IO expansion port, to achieve four stepper motor control.)

十速单片机写的密码锁程序，用汇编语言写的，刚开始学，写的不是很整齐(11-speed microcontroller write lock program written in assembly language, just started to learn to write is not very neat)

红外遥控解码，基于51单片机的例程，简单实用，我在学习单片机的时候用到的(Infrared remote control decoding, based on 51 MCU routine, simple and practical, I used the time to learn microcontroller)

MCS-51IO口模拟SPI读24位ADC（ADS1252）(MCS-51IO SPI port analog read 24 ADC (ADS1252))
