Cytron Technical Forum

hello,
i wanted to use cytron lsa08 line sensor on my arduino using uart. could anyone tell me how to do it?

Have you read through the user's manual?

Hi,
I tried lsa08 with serial UART communication
It works with digital output (UART mode 1) but it doesent with (UART mode 3)
anyone can help?
Thanks

If it works on UART mode 1, the LSA08 is working, I think you need to check your code. How your code handle the payload?

Can you post a working code please?
I checked my code but i don't understand what's wrong

Hi Le0pa_RD,

Could you share a few clear photos/videos of your hardware setup? Including the code that you write to Arduino.

Currently I don't have a sample code for LSA08.

This is my code.
Nothing wrong with the hardware.
UART mode 2 works as well it's just mode 3
can anyone help?

CODE: SELECT_ALL_CODE

const byte rx = 0;
const byte tx = 1;
const byte serialEn = 6;
int data[9];

void setup() {
  pinMode(serialEn,OUTPUT);
 
  digitalWrite(serialEn,HIGH);

  Serial.begin(9600);

}

void loop() {
  byte dummy = 0;

  for(int i=0; i<9; i++){
    digitalWrite(serialEn,LOW);
      while(Serial.available() <= 0);
    dummy = Serial.read();
    digitalWrite(serialEn,HIGH);
    data[i] = dummy;
  }

  if(data[0] != 0)
    Serial.println("Array not valid");
   
  else{
    Serial.print("Array: ");
   
    for(int i=1; i<9; i++){
      Serial.print(data[i]);
    }

    Serial.println();

  }
}

I tried with software serial too...
No results
Anyone?

How you do configure the LSA08 into mode 3?

In the UARTMODE menu on the sensor...
