Set the values to zero before averaging This is a sort of a filter for the inaccuracy of the reading
#Arduino stepper motor step direction update#
if the value is 25 "value away" from the average (midpoint), we allow the update of the speed Reading the potentiometer in the joystick:
tSpeed(5*(Analog_X-Analog_X_AVG)) ĭigitalWrite(enablePin, LOW) // disable the driver
nSpeed() // step the motor (this will step the motor by 1 step at each loop indefinitely)ĭigitalWrite(enablePin, HIGH) // enable the driver tAcceleration(1000) //ACCELERATION = Steps /(second)^2 setting up some default values for maximum speed and maximum acceleration InitialValues() // averaging the values of the 3 analog pins (values from potmeters) Int Analog_X_AVG = 0 //x-axis value average How could I write something like: if pin 2 goes high, stop motor in that direction, and then the same for pin 3 in the opposite direction? #include // accelstepper libraryĪccelStepper stepper(1, 8, 9) // direction Digital 9 (CCW), pulses Digital 8 (CLK)Ĭonst byte Analog_X_pin = A0 // x-axis readings If I have the switches connected to pins 2 and 3. I didn't write this code but it would work great if I could just add the end stops. I have hall switches for both ends, I just want it to stop going in that direction when it triggers the switch. I'm using one axis of a joystick to control a carriage that goes back and forth on a long screw. I need to add some end stops to this stepper motor code.
