Hi,I am testing a VL53L4CD sensor for a measurement application. I am using the example code from the API to test out the sensor and I'm having an issue with the minimum distance of the sensor. It will not report a measurement range less than 70mm an...
Hi, I was wondering if there was additionaly theory avaliable about the operation of the VL53L5CX TOF sensor? I've already read the datasheets and applications notes. I'm particulalry interested in how the SPAD array identifies the transmitted light ...
Hello all,We are currently considering using the VL53L4CD and other ToF / FlightSense products (e.g. the VL6180X) for close-proximity applications.Could you confirm or otherwise that the system field of view of the VL53L4CD - and other sensors based ...
I'm using the VL35L0X.ino demo code on an Arduino UNO and a clone VL53L0X sensor. I very carefully measured the off-perpendicular distance measurements obtained from the VL53L0X and compared them to actual tape measure measurements. On average there...
when I use VL53L5CX and get a status, then check with the table, but I still need further description than can explain STATUS means what.It's better like the picture below. Now I meet status 2, but I do not know why this happened.
Hello, I want to ask about the maximum range of VL53L1CB, as it says in the table (as seen in attached photo) that it's up to 8m. However, in data sheet or specification just says over 400cm.1) So is the performance should be good at 8m range outdoor...
I am attempting to write the platform code for the ULD to work with Zephyr. WrByte, RdByte, and RdMulti are running correctly, but the WrMulti function is throwing two types of errors:<err> i2c_nrfx_twim: Error on I2C line occurred for message 0<err>...
I'm trying to implement the VL53L5CX ULD v1.3.4 on an Atmel ATSAM4L. Per an Total Phase I2C analyzer, I have it almost all running correctly. It's uploading the firmware, and the firmware bytes captured by the I2C analyzer match the bytes in vl53l5cx...
Hello, i've been using a couple of VL53L4CX tof for a month with no problem so far, but recently i bought a few more and none of these work. (These new ones are the same model that the ones that worked).Analyzing with a digital osciloscope the I2C co...
Hi guys!From the last week I am trying to connect my TOF sensor with the STM32, but the I2C Communication has not been started. I have tried to use I2C Scanner to scan the address of the VL53L7CX SATEL breakout board but was not even able to gets i...
