We are working on syringe piston measurement application using VL53L0X for required accuracy of +/- 2mm.Overall we are getting required accuracy of +/-2mm. Sometimes we used to miss required accuracy.While analysis we came across one behavior of sens...
Original product brief showed both I2C and SPI peripheral communication available for the VL53L5 but the data sheet now focuses exclusively on I2C. Is SPI then no longer supported or can both/either be used with the appropriate user-provided platform...
From what I've read, I get that during a ranging sequence VL53L1CX performs two separate ranging operations and since we have also ambient data I think the sensor listens to the environment without sending any pulses. What I am curious about how they...
I have exposed both GPIO1 and GPIO2 pulled up to VDDIO with a 47 K resistor on my VL53L5 breakout. GPIO1 is used as the interrupt. What can I use GPIO2 for, another interrupt? It would be very convenient to have a date ready interrupt on GPIO1 and a ...
90% more or less of IR is absorbed per meter, whereas only 29% is absorbed for 500nm (https://www.britannica.com/science/seawater/Acoustic-properties). For underwater automation, it would be useful to have a TOF sensor that works at a different freq...
Interference between VL53L1X on mobile object.We use VL53L1X on mobile objects, and when these objects intersect we have interference between VL53L1X, we have incorrect measurementsIs it possible ? is a misuse of VL53L1XDo you have any examples, solu...
Hi,Readings from my VL6180X sensor are very unstable. They vary about +-8 mm from measure to measure.I tried with Nucleo board and official api, and also with Arduino board and Sparkfun code. 2,8V power supply is from linear regulator, measured objec...
Hi,i am trying to get STM32F301K8 to communicate with VL6180V1 ToF sensor on my custom board., via I2C (at 20kHz) I had problem getting the API to work so i tried low level I2C access by just sending 0x01 with basic HAL_I2C_Master_Transmit. I noticed...
Hello. I'm using a VL53L0X sensor with cover glass from www.gilisymo.com, so I need to do crosstalk calibration to get an accurate measurement. The problem is that the correction is too big. The process is as follows: 1) SPAD calibration (ok)2) Ref c...
