单片机做的4*4小键盘，学单片机的好资料，proteus仿真通过，学习的好资料...

单片机C语言初学教材，其中包括了很多关于单片机C语言的知识

用于步进电机的驱动.可以通过输出信号来控制步进电机的转速和角度控制.-For stepper motor driver. Can output signals to control the stepper motor speed and angle control.

红外遥控解码程序，清大家试试看，很容易看懂-Infrared remote control decoding process, money you give it a try, it is easy to understand

单片机C语言实现的对ROM进行测试的C语言的源代码。可供单片机开发人员参考。-SCM C language of the ROM to test the C-language source code. SCM developed for reference.

本程序是并口FLASH 39sf040读写程序,并给出调用函数.-This procedure is a parallel port to read and write FLASH 39sf040 procedures, and gives call function.

普通波形发生器 开发环境：VisualBadsic-General waveform generator development environment: VisualBadsic

这是用PIC芯片处理USB的源代码,包括初始化USB，中断设置等，是汇编语言入门USB操作的很好参考程序！-This is the PIC chip USB source code, including the USB initialization, interrupt settings, assembly language entry USB good reference operating procedure!

利用89S52为核心实现的IDE-USB转接器 现在已经实现了主要功能：可以读取文件和复制文件。不支持格式化硬盘功能。 不过速度比较慢，我从本地硬盘复制文件到移动硬盘里去，速度只有50KBytes/S， 因为单片机速度不快，内存又少，USB1.1的速度也不快。另外，代码写得不够好 压缩包内有线路图-89S52 realize use as the core of the IDE-USB adapter now realize the main function: You can read the files and copy files. Reformat your hard disk does not support the function. More slowly, however, I copy files from the local hard disk to a mobile hard drive into a speed only 50KBytes/S, because of slow single-chip, memory less, USB1.1 speed is not fast. In addition, the code written is not good enough compression packages have circuit diagram

以上是一些简单的单片机入门教程， 希望可以对刚学单片机的朋友有点帮助-These are some simple single-chip Tutorial, hope that we can just learn a little bit to help a friend SCM

视觉暂留，编程从一个I/O口输出一扫频信号，驱动一支LED灯闪动，频率范围为10HZ~99HZ，扫描时间为30秒，在LED闪动期间观察，一旦发现无法识别LED灯闪动时，按下按键K1，立即停止输出，并将此时的信号频率显示在数码管上，该信号的周期为测试者的视觉暂留时间。-Persistence of vision, programming from an I/O port outputs a sweep signal to drive an LED light flashing, the frequency range of 10HZ ~ 99HZ, scan time of 30 seconds, the LED flashing during the observation, once found it impossible to identify the LED lights flashing, press the key K1, immediate cessation of the output, and at this time the signal frequency displayed on the digital control on the test cycle of the signal" s persistence of vision time.
