Would you please write a short description of included keywords in front of every keyword for ' Adafruit_VL53L0X/keywords.txt '

I see that the api has VL53L0X_SetRangeFractionEnable.

Has anyone got this enabled and working? Plz share the code!

It isn't enabled by default and so measure.RangeFractionalPart always returns 0.

Hi,

I know this sounds weird, but it really appears to be the case here.
I can connect other sensors just fine (the TSL2591 for example), on an external power source too, and it just works. Note: i want to use an external power source because feeding the i2c censors i have via just arduino is simply going to draw too much current.
When i swap the wires from the TSL2591 to the VL53L0X, it simply fails with:

Adafruit VL53L0X test
Failed to boot VL53L0X

And yes, if i use the arduino (micro) to power the chip, it works just fine. I do have a common ground.

You probably need more information so i enabled debugging:

void setup() {
  Serial.begin(115200);

  // wait until serial port opens for native USB devices
  while (! Serial) {
    delay(1);
  }
  
  Serial.println("Adafruit VL53L0X test");
  if (!lox.begin(0x29, true)) {
    Serial.println(F("Failed to boot VL53L0X"));
    while(1);
  }
  // power 
  Serial.println(F("VL53L0X API Simple Ranging example\n\n")); 
}

Note the:

if (!lox.begin(0x29, true)) {

With that enabled, it spits out:

Adafruit VL53L0X test
VL53L0X Info:
Device Name: VL53L0X TS1, Type: VL53L0X, ID: ␃Ap8␜␎␇␃Ap8␜␎␇␃A
Rev Major: 1, Minor: 1
VL53L0X: StaticInit
VL53L0X Error: -50
Failed to boot VL53L0X

The error (-50) means:

/*!< In the function a division by zero occurs */
#define VL53L0X_ERROR_REF_SPAD_INIT ((VL53L0X_Error) -50)

Which clearly points at a code issue... Somewhere...
When further investigating that error, i found this thread:
https://community.st.com/s/question/0D50X00009XkYOCSA3/spad-initialization-error

Which has a response (from just one month ago) from a ST employee with an apparent fix. I'm not quite sure if that is "the" fix for this issue, i haven't testes it yet.

Is there any more information that is required of me to fix this?

Best regards,
Mark

Hello,

I was just wondering how can I change the different modes of the sensor with this library.

Let me know,

Thanks

I found these variables that are never used. Removing them can free up memory on the microcontroller.

Hi,

Is there a sample for continuous ranging mode?

Thanks

Problem: If one attempts to use this library as a part of another Arduino library, the sketch will not compile.
Reason: The source files in the \core and \platform contain header includes that do not have a path included, they point to header files within the same directory.
Solution:

1. Add "../../" to header includes in \core and \platform, or,
2. consider changing the directory structure so that these source files are in the same directory with the headers.

Hello, is there a way to enable a high speed mode on the sensor? It may just be shortening the period it takes to read/process...?

Platform

ESP32: Adafruit HUZZAH32 – ESP32 Feather Board (Firmware Release 1.0.2)
VL53L0X: CJVL53L0XV2

Problem

After burning example code into ESP32, serial prompts the following content and the board keep rebooting.
After switching to the pololu library, the board works just fine

  Thanks.

The definition of Adafruit_VL53L0X::rangingTest in Adafruit_VL53L0X.h doesn't return the status.

Routine VL53L0X_perform_offset_calibration from src/core/src/vl53l0x_api_calibration.cpp is giving strange results. By my opinion the problem is in uint16_t sum_ranging which should be of type
uint32_t due to later bit shifting (<<16), which needs to be done due to fixed point arithmetics.
(I was performing this calibration at 270 mm distance, which is due to documentation not optimal one, but after the fixes it works fine).

In case of VL53L0X_perform_xtalk_calibration the same goes for multiple variables (sum_ranging, ...) that accumulate the range measurements performed by the routine. Unfortunately there are some other errors present due to which the calibration routine doesn't produce an appropriate XTalkCompensationRateMegaCps value. Due to the lack of understanding what this calibration routine is trying to compute, I am not able to figure it out why.
(I was performing this calibraton at 600 mm distance).

Hello, i use this lib to read distance from VL53L0X. i use vl53l0x example to test but in serial monitor show

Adafruit VL53L0X test
Failed to boot VL53L0X

so i check communication between esp32 and VL53L0X via logic analyzer i found esp32 found 0x29 device address but in serial monitor show Failed to boot

How to fix this ?

Thanks !

Hello,

I try to connect multiple sensors but it retourn me just one fixe value when I connect the second sensor... Do you have an idea ? Thanks

The example uses a delay at the end of loop of 100 ms. How much can this be shortened?

I followed what claimed to be a link to documentation from this page and ended up at this repo. But I don't see any documentation here. Where is it?

My code looks like this:
lox.getSingleRangingMeasurement(&measure, false); Serial.println(measure.RangeMilliMeter);

The interrupt example doesn't work. The interrupt is simply ignored. I.e. the distance is displayed although only the range of 50-100mm should be displayed.

There are two equal expressions in this if statment

I use example code and everything works fine, but when I put the sensor without a barrier or to get out of range, the output from Arduino Serial Monitoring sometime shows random numbers such as 2mm or 4mm. How to solve this, just make sure the result/output is always out of range not random numbers.

The TOF sensor is currently due to my lack of understanding, hanging in a loop where it does not work properly.
I enabled debug mode and 'fiddled' around with the sensor untill the error occured.

sVL53L0X: PerformSingleRangingMeasurement
Range Status: 8 : No Update
RANGE IGNORE THRESHOLD: 15.60
Measured distance: 1

Between the PerformSingleRangingMeasurment and Range Status pass +30 Seconds.

A timeout if that error occurs would be great!
Thank you.

Thank you for opening an issue on an Adafruit Arduino library repository. To
improve the speed of resolution please review the following guidelines and
common troubleshooting steps below before creating the issue:

• Do not use GitHub issues for troubleshooting projects and issues. Instead use
  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
  something isn't working as expected. In many cases the problem is a common issue
  that you will more quickly receive help from the forum community. GitHub issues
  are meant for known defects in the code. If you don't know if there is a defect
  in the code then start with troubleshooting on the forum first.

• If following a tutorial or guide be sure you didn't miss a step. Carefully
  check all of the steps and commands to run have been followed. Consult the
  forum if you're unsure or have questions about steps in a guide/tutorial.

• For Arduino projects check these very common issues to ensure they don't apply:

  • For uploading sketches or communicating with the board make sure you're using
    a USB data cable and not a USB charge-only cable. It is sometimes
    very hard to tell the difference between a data and charge cable! Try using the
    cable with other devices or swapping to another cable to confirm it is not
    the problem.

  • Be sure you are supplying adequate power to the board. Check the specs of
    your board and plug in an external power supply. In many cases just
    plugging a board into your computer is not enough to power it and other
    peripherals.

  • Double check all soldering joints and connections. Flakey connections
    cause many mysterious problems. See the guide to excellent soldering for examples of good solder joints.

  • Ensure you are using an official Arduino or Adafruit board. We can't
    guarantee a clone board will have the same functionality and work as expected
    with this code and don't support them.

If you're sure this issue is a defect in the code and checked the steps above
please fill in the following fields to provide enough troubleshooting information.
You may delete the guideline and text above to just leave the following details:

• Arduino board: esp32-s3

• Arduino IDE version (found in Arduino -> About Arduino menu): latest - Platformio

• List the steps to reproduce the problem below (if possible attach a sketch or
  copy the sketch code in too):

Steps to reproduce:

• Use I2C multiplexer with with Adafruit_VL53L0X on esp32-s3.

This library calls begin() on the Twowire object, which is an issue when running the sensors on an I2C multiplexer, as the multiplexer needs to call begin() on the TwoWire object itself. This causes the I/O read timeout error to occur.

PR #49 was passing CI checks on its last commit. But after merging, CI is failing on missing dox. Not sure why that wasn't caught in the PR itself. Maybe the CI checks changed.

Anywho, need dox for:

@Vgdn1942 Can you make a follow on PR with dox?

There is a warning raised these days for not initialised things, and this has now bitten me when compiling this library into adafruit wippersnapper adafruit/Adafruit_Wippersnapper_Arduino#363 (comment)

pinging @brentru to stick on the backlog

In the file Adafruit_VL53L0X.cpp at line 100 it is written:

if( ( DeviceInfo.ProductRevisionMinor != 1 ) && ( DeviceInfo.ProductRevisionMinor != 1 ) )

I think this line should be:

if( ( DeviceInfo.ProductRevisionMajor != 1 ) && ( DeviceInfo.ProductRevisionMinor != 1 ) )

How do I connect the VL53L0X to the Arduino? Which pins do I use for SCL and SDA? And do I have to connect Xshut and GPIO?
Thank you!

@caternuson: I installed it with the arduino library manager, and did not modfify it. It seems there is/was(?) a problem with the way of installing. Maybe it's got some old or debug branch.

I'd like to "port" this library to put it onto the Particle Build IDE, but for that I'd like to provide a LICENSE file too.
I've downloaded the original STM API which comes with this license agreement
http://www.st.com/resource/en/license_agreement/dm00299899.pdf

And your lib looks pretty similar, so I'm not sure what license to include in my "port" to keep everybody happy and stay out of trouble ;-)

• Arduino IDE version (found in Arduino -> About Arduino menu): 2.10
  Library version 1.2.2
  Esp32 Runtime 2.0.9

Running on Generic ESP32 DEV Module this sketch
https://github.com/adafruit/Adafruit_VL53L0X/blob/master/examples/vl53l0x/vl53l0x.ino
Works fine using pins 21 and 22

On Esp32 S2 where i2c pins are 8 and 9 i get Failed to boot VL53L0X

I run a simple sketch to scan i2c connected and with both boards i get that there is a device connected at address 0x29 so is connected correctly.

Documentation page at http://adafruit.github.io/Adafruit_VL53L0X/html/index.html appears to be missing the documentation.

Hey,

I followed the setup for the vl53l0x as shown in --> https://learn.adafruit.com/adafruit-vl53l0x-micro-lidar-distance-sensor-breakout/arduino-code, but the program is not running correctly.

  Serial.println("Adafruit VL53L0X test");
  Serial.println("this is a test");
  if (!lox.begin()) {
    Serial.println("this failed to boot");
    Serial.println(F("Failed to boot VL53L0X"));
    while(1);
  }
  Serial.println("I got through the boot stage");

When I open the serial window, I get "Adafruit VL53L0X test" and "this is a test", but I don't get anything after that. This makes me think that the program is not getting by lox.begin().

Any advice?
Cheers

Expected behaviour
Building with USE_EMPTY_STRING defined reduces memory usage on memory constrained environments such as Arduino Nano.

Actual behaviour
Sketch fails to build due to several missing constants, eg: VL53L0X_STRING_ERROR_INTERRUPT_NOT_CLEARED

Environment
Tested on PlatformIO

Adafruit_VL53L0X.h can be imported multiple times causing name space errors at compile time.
