Issue with HC-SR04 Rangefinder

DawidBoTak · August 28, 2023, 4:13pm

On my arduino there are only TX1 and RX0, there are no other ones as far as i can see…

Anyway i will change everything in the code, i need front left and front right side, AND if one of the L1X sensors work, i will plug it into the I2C port and set it up as forward facing.

ok you will still need to modify the code to get the vl53l1x working but at least we have something to start with.

I will just plug it normally, without the arduino, and just simply set it in MP as forward facing.

good thinking, none of the other sensors are on the i2c bus now.

Alright so thank you so much for help and guidance, it was very interesting experience, stay safe!

I have had another go at the VL53l1x if you want to try it,

vl53l1x

github.com

geofrancis/POC/blob/master/MAVLINK-POC-VL53L1x.ino


#include <Wire.h>
#include <VL53L1X.h>
#include "mavlink/common/mavlink.h"        // Mavlink interface
#include "mavlink/common/mavlink_msg_distance_sensor.h"


// The number of sensors in your system.
const uint8_t sensorCount = 2;

// The Arduino pin connected to the XSHUT pin of each sensor.
const uint8_t xshutPins[sensorCount] = { 2, 3,};

VL53L1X sensors[sensorCount];

void setup()
{
  while (!Serial) {}
  Serial.begin(115200);
  Wire.begin();

It might be a good idea to rename this thread to something more relevant like “multiple vl53l1x and vl53l0x rangefinders”

to get your vl53l1x you have connected to the flight controllers i2c to show on the proximity display you will have to set PRX2_TYPE =4 so that the rangefinder is used for proximity.

Yes i know that, thank you again
