在JX44B0实验箱上实现功能键盘1实现步进电机正反转，2为使能键，3使步进电机加速转动，6使步进电机减速转动，9为退出键。-In JX44B0 test box to achieve realization of the stepper motor function keyboard 1 inversion, 2 to enable key 3 rotate the stepper motor acceleration, deceleration turn the stepper motor

实现触摸屏控制直流、步进电机的加速和减速、正反转；并在超级终端和液晶屏上同步显示转速-Touch screen control DC, stepper motor acceleration and deceleration, reversing speed and synchronized display in HyperTerminal and LCD screen

此代码的功能是通过控制ARM处理器的输出来实现对步进电机的正反转控制-This code function is controlled by the output of the ARM processor to achieve the stepper motor reversing control

STM32f4程序，控制松下伺服电机精确转动，包括正反转，启停，还有精确脉冲位置定位，硬件实现 效果最佳-STM32f4 program, panasonic servo motor control precision turning, including positive and negative turn, stop, and accurate pulse position location, hardware implementation effect is best
