VL53L1X - Interrupt(s) happening immediately after startMeasurement is called

In my setup I have VL531LX proximity sesor connected as per datasheet. Every time when I call startMeasurement interrupt is risen immediately after (often two interrupts). By user manual UM2356, figure 3. this clearly should not happen. I was wonder...

Could not receive the true unswer from VL53L1

Gentlemen! Sorry for bothering you.I try to use VL53L1 with the Light Driver. The power level is 3.0 V, so I changed the Initialization data array, cell 0x2E from 0x00 to 0x01 and cell 0x2F from 0x00 to 0x01. I wait for the Device ready (SensorState ...

Problems calibrating VL53L0X ToF distance sensor (VL53L0X_perform_offset_calibration, VL53L0X_perform_xtalk_calibration). bug?

RoutineVL53L0X_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 ...

How can we detect a target if it doesn't cover the FoV(i.e., a target smaller than the FoV)?

If it's not doable, what is the reason for that? (why the distance cannot be measured with the VL53L1X if a target is smaller than its FoV?)​

I would like to use the VL53L0x to measure the height of liquids in the holding tank and water tanks of a boat. Is this likely to work? Distances are 5 cm - 50 cm

Can I place a "window" of thin mylar or glass in front of the sensor at a distance of 1 cm or so to shield it from the liquids in the tanks?

For VL53L1X, we have planned to use multiple sensors in a single bus. For that we have changed the address of the sensor and worked. But for every power cycle the sensor resets to it factory address (0x29). How can we change the address

VL6180X Bus Lockup

In our design the Proximity sensor is locking up in 90% of the boards. It ranges properly on its own. But when added to the bus, rest of the sensors function properly and only VL6180X is locking up. This is an ongoing issue.In the boards where its fa...

I2C issue on STM32F746G with VL53L1X breakout board.

Hello everyone, I've a problem with the communication I2C. I've generated the I2C communication base code with STCubeMX for the STM32F746G discovery board. And I got an error at I2C_WaitOnTXISFlagUntilTimeout(). Because NACK is detected. I've also te...

VL53L0X API and Arduino

Dear All,I´d really apreciate if you could give me some guidance about how to use the VL53L0X API in Arduino as it is my first time that I face it. More specifically, how I should "install" the API software before playing with the examples included...

There is no RefSPAD calibration in VL53L1X ULD driver. How to peform RefSPAD calibration if VL53L1X ULD driver is used ?
