针对51单片机的中断触发按键的程序，利用P3.2口接行列按键。...

控制步进电机正转，如：p3.2正转,p3.3反转,p3.4停止 步进电机接p1.0p1.1p1.2p1.3，正转，反转各3圈，正反快慢功能，是步进机的经典程序。-Stepper motor control is transferred, such as: p3.2 is transferred, p3.3 inversion, p3.4 stop stepper motor then p1.0p1.1p1.2p1.3, is turn, reversal of the 3 lap, both positive and negative speed function, is a classic step process machine.

基于单片机和0808的16位数据采集系统，通道可控-Based on a 0808 MCU and 16-bit data acquisition system and access control

单片机proteus仿真，可以做成实例的仿真文件-proteus proteus

单片机控制122x32液晶。液晶内部芯片包含RAM（类似于显存），当然不具备2D3D加速。不过，功耗非常低，一般几个毫瓦。-SCM 122x32 LCD. LCD chip contains an internal RAM (similar to memory), of course, does not have to speed up 2D3D. However, power consumption is very low, generally a few milliwatts.

是protel的讲义，应该有利于大家的学习-Yes protel lectures, should be conducive to our learning

C51单片机学习的好实例，好好学习哟，-C51 single-chip learning good examples to learn yo,呵呵呵~ ~ ~ ~
