51单片机控制2相步进电机C程序，环境为KEIL开发环境-51 2-phase stepper motor microcontroller control C program, the environment for the KEIL development environment

仅仅使用L298驱动芯片，主控为51单片机，在keil中调试测过，专门驱动步进电机的！不是直流电机。-Just use the L298 driver chip, the master microcontroller 51, in keil debugging measured before, specifically to drive stepper motor! Not a DC motor.

基于51单片机控制的GPRS模块，主要功能是检测三相交流电的的工作情况，用交流互感器检测三相的电流变化，传给单片机，单片机通过串口控制GPRS模块发送信息，这时可以了解电机的工作情况-Based on 51 single-chip control of the GPRS module, the main function is to detect the work of three-phase alternating current, AC three-phase current transfo

51单片机端口模拟PWM输出控制直流电机，代码经调试无误，在51单片机上可使用-51 single-port analog DC motor control PWM outputs, the code after debugging is correct, the microcontroller can be used in the 51

本程序是基于at89s51单片机软件产生PWM控制直流电机转速的程序，希望对大家有用。-This program is at89s51 microcontroller software program PWM control DC motor speed, the hope that useful.
