电子图书《华中理工大学出的C51教材》，很不错的。

这个程序是控制无线模块2401接受，为51系列单片机控制。可以将接收到的字节上传到电脑的串口-This procedure is to control the wireless module 2401 to accept for the 51 series single-chip control. Can be received bytes uploaded to the computer

用L298作为驱动器，控制两相混合式步进电机。 按键从上至下分别为减速，加速，正转，反转，停止。 具体参数还没有设定过。速度有些慢，加速按2下有效，然后就不能再快了。 转速输出是按照最小系统版的数码管写的。电路图里太麻烦就没画了。-Using L298 as the drive to control two-phase hybrid stepping motor. Buttons from top to bottom respectively, deceleration, acceleration, are being transferred, reverse, stop. Specific parameters have not yet been set. Some of the slow speed, speed up by 2, effectively, and then can not be faster. Speed output is in accordance with the minimum system version of the digital tube wrote. Circuit where not too much trouble drew.

是用ATmega162单片机控制1602LCD液晶显示的C语言源代码，包括了显示一个字符或一个字符串的功能-ATmega162 microcontroller is used to control 1602LCD LCD C language source code, including a show or a character string function

自制的串口控制8路光藕隔离输出，可以通过计算机串口控制，8路输出-homemade serial control a variety of eight-channel optical output isolation can be controlled via computer serial port, eight output

前一阵子做了个IC卡读写程序，可以读写SLE4442系统逻辑加密卡的，本来想在网上找一个，没找到，自己写了一个，为了让后来人可以轻松一点，所以就奉献给大家：） 注释比较少（本人的坏习惯），看起来有点累，不过建议你在自己看之前先熟悉一下SLE4442的协议。 程序是经过测试的，在我的931上工作的很好，有什么问题，发信给我 Ploto_zhu@etang.com-done a while ago, IC card reader procedures, can read and write SLE4442 encryption system logic card, and they would like to find an on-line, could not find himself writing a view to the later can easily point and so on devoted to you :) Notes relatively small (my bad habits), looks a bit tired, but I suggest you look at before their first study SLE4442 agreement. Procedures are tested, in my 931 on the good work and what problems, I wrote to Ploto_zhu@etang.com
