步进电机加减速控制

本设计使用P89V51RD2控制直流电机的正反转与加减速,电机驱动芯片选用L298N.

51单片机控制电机加减速的语言，比较实用的控制单元。-51 MCU control motor acceleration and deceleration of the language, more practical control unit.

按键控制单片机,可以实现直流电机和步进电机的正反转加减速等-Keys to control the microcontroller, the DC motor and the stepper motor acceleration and deceleration can be achieved

速度控制使用两个按键及与非门，共用一路外部中断，速度测量使用一路外部中断，从而实现加减速控制与速度测量的同时实现-Speed control using two buttons and a NAND gate, share a common external interrupt, velocity measurement using an external interrupt, and realize the speed control and speed measurement at the
