Hilfe bei einen Nema 17

Gleiche Funktion
im Prizip sehr ähnlicher Programmaufbau
andere Variablennamen

const byte stepPin = 4;
const byte dirPin  = 7;

unsigned long myStepTimer;

const unsigned long fullStepsRev = 200UL;
const unsigned long microsteps   = 16UL;
const unsigned long stepsRev     = fullStepsRev * microsteps;
const unsigned long rpm = 1;

const unsigned long pulseWaitMs = (1000UL * 60UL) / (stepsRev * rpm); 

unsigned long PulseHighMicroSecs = 200;


void setup() {
  pinMode(stepPin, OUTPUT); //Define pins and set direction
  pinMode(dirPin,  OUTPUT);
  digitalWrite(dirPin, LOW);
}


void loop() {
  if ( TimePeriodIsOver(myStepTimer,pulseWaitMs) ) {
    oneStepPulse();
  }
}


void oneStepPulse() {
  digitalWrite(stepPin,HIGH);
  delayMicroseconds(PulseHighMicroSecs);
  digitalWrite(stepPin,LOW);
}


// easy to use helper-function for non-blocking timing
// explanation see here
// https://forum.arduino.cc/t/example-code-for-timing-based-on-millis-easier-to-understand-through-the-use-of-example-numbers-avoiding-delay/974017
boolean TimePeriodIsOver (unsigned long &startOfPeriod, unsigned long TimePeriod) {
  unsigned long currentMillis  = millis();
  if ( currentMillis - startOfPeriod >= TimePeriod ) {
    // more time than TimePeriod has elapsed since last time if-condition was true
    startOfPeriod = currentMillis; // a new period starts right here so set new starttime
    return true;
  }
  else return false;            // actual TimePeriod is NOT yet over
}

damit haste jetzt funktionierenden Code aber null gelernt.

Ist das das was du willst?
