Storing sensor data in an array

Other Hardware Sensors
9

Well, I had thought that once j>255 the code would never leave this while loop and would just output the data stored in the array. I realize that the first for loop should have been outside the while loop for this to work but I had tried that previously and I still got the same issue. Like the code below:

#include <DueAdcFast.h>

DueAdcFast DueAdcF(1024);

// 1024 measures is dimension of internal buffer. (min is 1024)

unsigned long period;
unsigned long spaceLength;
unsigned long pulseWidth;
unsigned long oldPeriod = 0;

int inputSignal;
int start1;

unsigned long endTime;
unsigned long lowTime;
unsigned long midTime;

int frequencyINPUT;
volatile int x;
int b;
int y;
int i=0;
int j;
int z;

uint32_t sensorSignal;  // the variables of your code.

float getround; 
int rounded;
int finalval;

int pulseWidths[255];

void setup() {

  start1 = 0;  
 
  Serial.begin(115200);

  // indicate the pins to be used with the library. 
  DueAdcF.EnablePin(A7);
  //DueAdcF.EnablePin(A1);

  // indicate at what speed in the background 

  DueAdcF.Start1Mhz();       // max speed 1Mhz (sampling rate)

  //DueAdcF.Start();         // normal speed 667 Khz (sampling rate)
  
  //DueAdcF.Start(255);      // with prescaler value form 3 to 255.
                             // 255 is approx. 7812 Hz (sampling rate)
 
}


// these 3 lines of code are essential for the functioning of the library
// you don't call ADC_Handler.
// is used automatically by the PDC every time it has filled the buffer
// and rewrite buffer.
// 
void ADC_Handler() {
  DueAdcF.adcHandler();
}


void loop() {

 //y = micros();
 
 sensorSignal = DueAdcF.ReadAnalogPin(A7);  
   
 
  if (sensorSignal < 1800 && start1 == 0) //detects first tooth and starts to read the output signal from the sensor (PART 1 ON DIAGRAM 1.)
  {

    start1=1;
   

  }

  if (sensorSignal > 1800  && start1 == 1)  //reads that the sensor has gone low and records the time  (PART 2 ON DIAGRAM 1.)
  {

    start1=2;
    lowTime = micros()*0.01;  
     

  }

  if (sensorSignal < 1800  && start1 == 2)  //reads that the sensor has gone high and records the time  (PART 3 ON DIAGRAM 1.)
  {

    start1=3;
    midTime = micros()*0.01;

  }
  if (sensorSignal > 1800 && start1 == 3)  //reads that the sensor has gone high and records the time  (PART 1 ON DIAGRAM 1.)
  {

    start1=1;
    endTime = micros()*0.01;
    
    spaceLength = endTime - midTime;
    period = endTime - lowTime;
    pulseWidth = period - spaceLength;
  }  
     i

    Serial.print(sensorSignal);
    Serial.println();

    for ( i = 0; i < 254; i = i + 1) {
     pulseWidths[i] = pulseWidth;
    }

  while(i>255)
  {
       for ( z = 0; z < 254; z = z + 1) {
      Serial.println(pulseWidths[z]);
      
    }
    }
}
