TF mini Multiple sensors on the Arduino Mega.

Using Arduino Sensors
14

I have done 2 arduino projects before this. My mainstay is C Matlab, Inventor, FEA, very new to this stuff, I am also a SCADA engineer. literally learning this stuff before i interface the sensors in LABview. I have tried the following code. I think i have most of it right I just need to initiate the read which I am struggling to grasp the concept of. If you could help me out i would be most grateful.

Also I am new to the forums. My code compiles I am just missing something to initiate the reads. Code below.

#include <Wire.h>

int dist;//actual distance measurements of LiDAR
int strength;//signal strength of LiDAR
int check;//save check value
int i;
int uart[9];//save data measured by LiDAR
const int HEADER=0x59;//frame header of data package


void lidarData();

void setup() {
  Serial.begin(9600);//set bit rate of serial port connecting Arduino with computer
  Serial2.begin(115200);//set bit rate of serial port connecting LiDAR with Arduino
    
}

void loop(){

  
 if (Serial2.available()>0)//check if serial port has data input also greater than 0 
  {
    if(Serial2.read()==HEADER)//assess data package frame header 0x59
    {
      uart[0]=HEADER;
      if(Serial2.read()==HEADER)//assess data package frame header 0x59
      {
        uart[1]=HEADER;
        for(i=2;i<9;i++)//save data in array
        {
          uart[i]=Serial2.read();
        }
        check=uart[0]+uart[1]+uart[2]+uart[3]+uart[4]+uart[5]+uart[6]+uart[7];
        if(uart[8]==(check&0xff))//verify the received data as per protocol
        {
          dist=uart[2]+uart[3]*256;//calculate distance value
          strength=uart[4]+uart[5]*256;//calculate signal strength value
          if(dist>=30 && dist<1200)
          {
             Serial.print(dist);//output measure distance value of LiDAR, z-coordinate
             Serial.print("\n");
             Serial.flush();
          }
        }
      }
    }
  }
