Description: Considering the resources of the microcontroller and the actual work needs, it is necessary to complete the maximum speed start and accelerate the whole process in the 255 acceleration steps, and when the actual required (maximum) speed changes with each execution task change, we The program design in accordance with the maximum speed of the work object to calculate the parameter table, before starting the motor running before the need to walk the total number of steps to convert the maximum number of steps to accelerate, basically in accordance with the three 1/3 of the way to convert,/3 of the number of walking steps for acceleration, 1/3 for high-speed operation, 1/3 to complete low to low speed to stop the speed to achieve automatic speed control. According to the actual needs can also be 2/5-1/5-2/5 program speed, the motor to complete the total number of steps shorter time, and sometimes in order to ensure that the motor has enough output torque can also set a maximum limit The
