Hi all, What is the part to part variation of ST VL6180 ToF sensor? During testing, we keep the sensor at a distance of 50mm from a retro reflector tape. In a batch of 50 sensors, the readout was from ~ 37 mm to ~51 mm (expected readout is 5...
Hi allI have successfully implemented a single vl53l0x sensor, but wish to add more. I found the "AN4846 Application note Using multiple VL53L0X in a single design" documentation:https://www.st.com/content/ccc/resource/technical/document/application_...
Hello, We've been developing a tank level monitoring system using these sensors: VL53L4CD (18° FoV)VL53L3CX (25° FoV, multitarget)VL53L4CX (18° FoV, multiobject, multitarget) First question is the definitions and distinctions between the terms multiz...
Hi there, I read this document and it mentioned that the function "vl53l8cx_set_VHV_repeat_count" can be used to compensate for the ranging error caused by temperature. I would like to know the principle of VHV calibration compensation. Is it relat...
@John E KVAMI ported the gesture recognition example (STSW-IMG035_F401) from the STM32F401RE to the NUCLEO-U575ZI-Q with the X-NUCLEO-53L8A1 and the gesture library (STSW-IMG035_M33). If I used the VL53LMZ_ULD_API driver included with the GestureKit...
Currently I connected the X-NUCLEO-53L8A1 to F401RE, and I notice that on the web page of VL53L8CH, the sensor can get the data with 64 zones with 18 bins at 15 Hz. But when I use the VL53L8CH with the Example_12_cnh_data which use VL53LMZ_ULD_API, I...
Hello,I'm currently using VL53L8CX with an STM32U535 on a custom PCB.I'm using X-CUBE-TOF1 package.I'm able to identify the sensor with SPI at 2MHz using vl53l8cx_is_alive function.I was able to successfully init and use VL53L8 on U-585I-IOT02A dev b...
Hi everyone, I am currently using the VL53L8CX for people counting. However, I have encountered an issue where occasionally, changing the data acquisition rate during the data collection process causes a disruption and prevents further data acquisiti...
HiI refer to the VL53L0X Datasheet DoclD029104 rev5 page 15 article 2.10 Ranging Sequence.There not a lot descritption in your documentI need to understant how GPIO1 stay down before the sensor pull it up when init/ranging/housekeeping phase is finis...
As far as I know, dToF has two illumination modes. One is spot dToF (iPhone) and the other is flood illumination. Which one is VL53L8CH? Thanks.
