Update -> I think the answer is that there is an interrupt resetting these values in between setting them to zero and printing them.
I am trying to calibrate my motors and am having trouble. In particular, how is this output:
Resetting Quadrature: 0: 92072 1: 92083
possible for this function:
void processQuadrature(){
long now = millis();
Serial.print(“Quadrature 0 = “);
Serial.print(float(quadrature0Pulses*1000)/(now-quadrature0Start) );
Serial.print(” pulses per second over “);
Serial.print(now-quadrature0Start);
Serial.println(” milliseconds”);
Serial.print(“Quadrature 1 = “);
Serial.print(float(quadrature1Pulses*1000)/(now-quadrature1Start) );
Serial.print(” pulses per second over “);
Serial.print(now-quadrature1Start);
Serial.println(” milliseconds”);
quadrature0Start = 0l;
quadrature1Start = 0l;
quadrature0Pulses = 0l;
quadrature1Pulses = 0l;
Serial.print("Resetting Quadrature: 0: “);
Serial.print(quadrature0Start);
Serial.print(” 1: ");
Serial.println(quadrature1Start);
}
That is, haven’t I just set these two variables to zero before I print them out?
Can this have something to do with interrupts?
TIA
