51单片机6个io口21个按键的设计源程序，并且具有单击双击，长按功能！(51 microcontroller 6 io port 21 key design source, and double-click-click, long press function!)

24CXX的读写代码,适用于于51单片机SCM.可直接使用。 (24CXX the read and write code, suitable for 51 MCU the SCM can be used directly.)

ADS1258开发，程序源代码，还要20字 好恶心(ADS1258 development, source code, but also the word disgusting 20)

电脑鼠底层驱动，能实现曲线转弯，速度快，很平稳(Computer mouse driver, can realize curve curve, speed, very smooth )

说明：  基于飞思卡尔DG128的方波，适合学生学习(Based on Freescale DG128 square wave, suitable for students)

iic接口的程序，可以用于f149单片机(iic interface procedures can be used F149 microcontroller)

驱动步进电机，旋转多次，寻找空间光强极大值初步程序(Drive stepper motor rotation several times to find space intensity maxima preliminary program)

一个电表行业专用的基于645规约的电表485通讯抄表程序，可以进行485总线抄表，645规约测试。程序技术要点就是规约数据传输协议的处理，如向电表发送数据时的控制码和数据长度、发送的数据部分(数据标识 + 密码 + 数据)、应答帧长度、结束标志等通讯协议的处理值得大家学习。(A meter-based industry-specific statute 645 meter 485 meter-reading procedure can be carried out 485 meter, 645 Statute of the test. Procedures for the technical elements of the statute is to deal with data transmission protocols, such as sending data to the meter when the control code and data length, send the data section (data logo+ Password+ Data), response frame length, marks the end of the treatment protocol, etc. everyone deserves to learn.)

本文讲述了细分驱动技术的原理，重点介绍了细分驱动控制系统的设计方法，设计了一套传统细分驱动系统的设计方案，在此基础上，本文进一步介绍了L297、L298两块芯片，采用这两块芯片构成步进电机的驱动电路，应用DAC0832实现D/A转换，采用精简指令集单片机AVR作为脉冲产生器，对步进电机的工作过程进行控制，最终组成电机细分数可选的驱动控制系统。(failed to translate)
