步进电机加减速运行程序 步进电机启动时，转速由慢到快逐步加速 步进电机匀速运行 步进电机由快到慢逐步减速到停止-Stepper motor stepper motor deceleration run the program starts, the speed gradually from slow to fast speed stepper motor stepper motor run by a uniform approaching slowly and gradually slow down to stop

this program tell you how to connect ps2 to a mcu(for example at89s51)-this program tell you how to connect to a ps2 mcu (for example at89s51)

PWM控制输出电压由于该程序所需完成的功能比较简单，设计时采用了简单的前后台组织结构：后台程序（主程序）在非通讯状态时工作，完成各项数据的采集和预处理，并标准化至通讯协议所规定的格式。这一过程不停进行，随时提供最新数据；前台程序（中断服务程序）在接收到来自控制器的命令时启动。它对命令加以识别，并按要求向控制器传送相应数据或对数据进行解析执行。该程序的流程示意如图-PWM output voltage control due to the completion of the procedures required for the function of a relatively simple design, a simple organizational structure around Taiwan : background (main program) in non-state communication, complete data acquisition and pre-processing, and standardized communication protocol to the format provided. This process conducted on a continuous basis and provide the latest information; Prospects (interrupt service routine) from the receiving controller to activate the orders. It ordered to be identified, together with a request to the controller or corresponding data transmission for data analysis implementation. The indicative of processes figure
