How to read temperature values while the stepper motor is moving (non-blocking))

what about something like

int step;
unsigned long usecLst;

void loop ()
{
    if (step)  {
        unsigned long usec = micros ();
        if (usec - usecLst >= stepSpeed)  {
            usecLst = usec;

            if (LOW == digitalRead (stepPin))
                digitalWrite (stepPin, HIGH);
            else {
                digitalWrite (stepPin, LOW);
                step--;
            }
        }
    }

    // read temp values
    if (millis () - lastReading >= interval) {
        temperatureReadings ();
        lastReading = millis ();
    }

    // check if the user has entered any input
    if (Serial.available ()) {
        char buf [80];
        int n = Serial.readBytesUntil ('\n', buf, sizeof (buf)-1);
        buf [n] = '\0';

        if ('s' == buf [0])  {
            sscanf (buf, "s%d", &step);
            Serial.println (step);
        }
    }
}
