High Resolution Gyro Question

I believe I did that with this code:
It was printing and scrolling through what looks like HEX.

// Example 6 - Receiving binary data - from Arudino Forum
#include <LiquidCrystal.h>
LiquidCrystal lcd(10, 9, 8, 7, 6, 5);       // put your pin numbers here

const byte numBytes = 6;
byte receivedBytes[numBytes];
byte numReceived = 0;

boolean newData = false;

void setup() {
    pinMode(11, OUTPUT);    // LCD CONTRAST PIN
    pinMode(2, OUTPUT);    // Clear To Send PIN
    pinMode(3, OUTPUT);    // Clock PIN
    digitalWrite(2, HIGH);  // CTS CONSTANT HIGH
    tone(3,32); //CLOCK FREQ in HZ
    analogWrite(11, 79); //LCD CONTRAST AMOUNT
    Serial.begin(1000000);
    
    // set up the LCD's number of columns and rows:
    lcd.begin(16, 2);
}

void loop() {
    recvBytesWithStartEndMarkers();
    showNewData();
}

void recvBytesWithStartEndMarkers() {
    static boolean recvInProgress = false;
    static byte ndx = 0;
    byte startMarker = 0x3C;
    byte endMarker = 0x3E;
    byte rb;
   

    while (Serial.available() > 0 && newData == false) {
        rb = Serial.read();

        if (recvInProgress == true) {
            if (rb != endMarker) {
                receivedBytes[ndx] = rb;
                ndx++;
                if (ndx >= numBytes) {
                    ndx = numBytes - 1;
                }
            }
            else {
                receivedBytes[ndx] = '\0'; // terminate the string
                recvInProgress = false;
                numReceived = ndx;  // save the number for use when printing
                ndx = 0;
                newData = true;
            }
        }

        else if (rb == startMarker) {
            recvInProgress = true;
        }
    }
}

void showNewData() {
    if (newData == true) {
        lcd.clear();
        for (byte n = 0; n < numReceived; n++) {
            lcd.print(receivedBytes[n], HEX);
        }
        newData = false;
    }
}
