URGET serial.Write() question...

I am trying to read data info from two ultrasonic sensors and transmitt them bak to back.
Here is my code, it doesnt transmit for some reason, it is going through the loop and it is emabling the sensors to read but it doesnt transmit. TX LED doesnt flash. ANY idea will be extremely appreciated.

const int pingPin1 = 7; // CONNECT SENSOR 1 to pin 7
const int pingPin2 = 8; // CONNECT SENSOR 1 to pin 7

long DataAvg[8];

void setup() {
  // initialize serial communication:
  Serial.begin(115200);
  
  // initialize the data averaging filter
  int i;
  for(i = 0; i < 8; i++)
  {
    DataAvg[i] = 0;
  }
}

int ping(int pingPin)
{
  // establish variables for duration of the ping, 
  // and the distance result in inches and centimeters:
  long duration, mm;

  // The PING))) is triggered by a HIGH pulse of 2 or more microseconds.
  // Give a short LOW pulse beforehand to ensure a clean HIGH pulse:
  pinMode(pingPin, OUTPUT);
  digitalWrite(pingPin, LOW);
  delayMicroseconds(2);
  digitalWrite(pingPin, HIGH);
  delayMicroseconds(5);
  digitalWrite(pingPin, LOW);

  // The same pin is used to read the signal from the PING))): a HIGH
  // pulse whose duration is the time (in microseconds) from the sending
  // of the ping to the reception of its echo off of an object.
  pinMode(pingPin, INPUT);
  duration = pulseIn(pingPin, HIGH);

  // convert the time into a distance
  mm = (duration / 3) / 2;
  
  // Filter the data
  int i;
  long FiltData = 0;
  for(i = 7; i >= 1; i--)
  {
    DataAvg[i] = DataAvg[i-1];
    FiltData += DataAvg[i];
  }
  DataAvg[0] = mm;
  FiltData = (FiltData + DataAvg[0]) >> 3;
  
  // Truncate the data if it's too big so the value is contained within a single byte
  int pingData = 0;
  if(FiltData >= 255)
    pingData = 255;
  else if(FiltData <= 0)
    pingData = 0;
  else
    pingData = FiltData & 0xff;

  return pingData;
}

void loop()
{
  // Send the data
  Serial.write(ping(pingPin1) >> 1);
  delay(100);
  Serial.write((ping(pingPin2) >> 1) + 0x80);
  delay(100);
}

Did you just check the TX LED or did you check with the serial monitor too? If there's any problem with the sensors the LED may be lit for about 1ms every 2-3 secs. I don't expect your eyes to see that.

oh yes I did. Also arduino is connected to the FPGA and FPGA doesnt recieve anything either.

In this case provide the (complete) wiring diagram of your project.

So from your point o view, the code is right. right?
do you think that is a hardware/wiring fualt?

It's not possible to understand the software without also understanding the hardware.
