Nager.ArduinoStepperMotor

This project was developed to control a stepper motor smoothly and to adjust the speed during operation. Most of the libaries I tested at that time had an acceleration curve but always stopped when changing to another speed and then started again. There are two ways to communicate with the Arduino, one is via serial communication or by using a network module. If you have difficulties and the motor only whistles you should adjust the acceleration curve in the Arduino file.

Serial Commands (Baudrate 115200)

Command	Description
enablemotordriver	Enable the motor driver, the motor has voltage
disablemotordriver	Disable the motor driver, the motor has no voltage
speed	Values between -255 and 255
limitenable	The motor can only move between the limits
limitdisable	No limits active
setlimitleft	Set the current position as left limit
setlimitright	Set the current position as right limit
step	Motor move one step
ramp	Returns the current ramp
setramp	Set a new ramp (setramp=0008000) rampIndex 0 -> 8000
