Resolved! VL53L5CX works as expected when I ask for VL53L5CX_RESOLUTION_4X4. However, when I ask for VL53L5CX_RESOLUTION_8X8 not so much.
The first pixel of each of eight rows seems to provide a good range estimate in mm but the rest of the data is either zero or some huge number that doesn't respond to changes in the field of view. I assumed I would get 64 range estimates as output of...
VL53L5 Thresholds
Is there any documentation how to setup the various threshold parameters? These are the macros defined in the vl53l5cx_plugin_detection_thresholds.h#define VL53L5CX_DISTANCE_MM ((uint8_t)1U)#define VL53L5CX_SIGNAL_PER_SPAD_KCPS ((uin...
Resolved! Clarification on how VL53L0X and VL53L1X calculate distance from photon bin counts
Could someone please shed some light on the algorithm the VL53L0X and VL53L1X use to calculate the distance from the returned photons for each laser pulse? @John E KVAM you’ve mentioned in other blogs that photons seen are “averaged�? – is the logi...
How to use ST VL5310X Time of Flight sensor Library in Silicon Labs Simplicity studio.
I'm using Zigbee3 with Silicon labs EFR32MG21A020F. I want to read the Distance of ToF sensor which is based on ST library. They mentions that it support multiple IDE. I want to know how to use it in simplicity studio 5. Can anyone help me to figure ...
VL53L1 returns 65XXX values
I have multizone ranging mode enabled along with SHORT distance mode.I am getting a lot of readings with 65XXX values, for example:[8191, 65277, 65243, 65257, 65312, 65267, 65238, 65168, 65241, 65263, 65239, 65211, 65227, 8191, 65217, 65173, 65244][8...
VL53L5CX Examples (9 & 11) using interrupt
I'm using a X-NUCLEO-53L5A1dev board that I have wired up to a Raspberry Pi. I have also wired the interrupt line from dev board (cn-8 pin 3) to the Raspberry Pi GPIO1 (pin 28 on the 40 pin header). In the examples 9 and 11 there is a dummy functio...
Resolved! VL53L5CX:What does Status 6 mean.
More specifically, the doc's say status 6 means "wrap around not performed". What is wrap around? Is this a bad condition?Thanks,Dave
Resolved! Issues while interfacing two VL53L1X sensors using Esp32
Hi ST team and community!I am trying to develop a People Footfall Counter for commercial use using the two VL53L1X Sensors on Esp32 using the Sparkun Library from the following:https://github.com/sparkfun/SparkFun_VL53L1X_Arduino_LibraryFirst of all,...
Resolved! VL53L0X API: Usage of the 6 limit checks, Ambient SPAD damper, Dmax Cal, etc
Hello,I have spent some time reading through the VL53L0X API and all documentation related to this sensor.I was hoping your team could clarify the usage of a few functions and features."Pre-Range" vs "Final-Range"This distinction is made througout th...
