Question regarding VL53L1X_StopRanging()
According to the VL53L1X ULD API description when Vl53L1X_StopRanging() is called, an active ranging operation will be completed.In a practical evaluation we tried to investigate whether an interrupt could still occur after calling this function or n...
Evaluating the quality of a cover window by measuring crosstalk
In the production process of a product using the VL53L1X TOF sensor we would like to evaluate the quality of the custom assembled window. There are some mechanical tolerances and we need to ensure that the crosstalk is as low as possible. Is there a...
Resolved! VL53L1 and VL53L3CX not found in i2C Scan
Hi thereI can't find out how to connect my sensor to an arduino uno. Tried both with sample codes from SparkFun and i2C example code. It is connected in the following way:SCL -> SCLSDA -> SDAGND -> GNDVDD -> 5VI also tried with 2K ohm pull-up resisto...
Resolved! Can you please provide github URL for VL53L1X UAPI source code?
Hi,I found several issues and want to contribute. Please share the ultra light wight API source code for the VL53L1X.Thanks!
For the VL53L0X Emitter Exclusion Zone, what happens if the zone is breached?
I am adding a VL53L0X to an existing board design, and would like to keep the same footprint. A relatively small section of the emitter exclusion zone is breached ~16mm away from the top surface so I am curious what the effect would be and how signif...
Resolved! Which I2C address to the ST ToF sensors use?
The ST data sheet says: “…uses a default device address of 0x52.But is that the 7-bit base address, or the Write address?
Does enybody know if I can change ROI dynamically in VL53L1X time-of-Flight Distance Sensor.
Hello, I have a question of VL53L1X time-of-Flight Distance Sensor. The VL53L1X features a programmable region of interest (ROI), so the full field of view can be reduced or divided into multiple zones. I want to know if I can change ROI dynamically....
VL53L0X GPIO Interrupt did frequent / irregulary not trigger and unexpected trigger when no target present
I have invested a lot of time and find no solution: I use two VL53L0X sensors in a custom board design with an ESP32 and use of the ST-Library functions. The usage of the GPIO Interrupts did not work as expected, because frequently / irregulary they...
