Resolved! Asking the illumination mode of VL53L8CH.
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.

Resolved! Please check my observations about AN5894
Are formulas 1-4 correct in AN5894?Segment [AC] is the hypotenuse of triangle ACE, and the angle between segments [AC] and [CE] is half the dihedral angle HFOV. Then formula 1 should have a sine instead of a tangent.If I am right, in the example the ...

Resolved! VL53L8xx SPI & daisy-chain support
Hi!I’d like to know if the Vl53L8xx product series support “SPI daisy-chaining” ?For a project, I’ll need few of those, either “straight” along a line segment ( +/- like Neonode’s ZForce sensor bar ), as a “grid”, or as an “arc section” ( that is, a ...
Resolved! VL53L4CX meaning of CalibrationData
Hi，I would like to know the meaning of each data in the L4CX calibration data(VL53LX_CalibrationData_t in API）, because there is a lot of data for this IC, and I would like to confirm the status of the calibration from the data.Thank you.
SATEL-VL53L8 + ESP32 => VL53L8CX ULD Loading failed
Hello everybody,I have connected a SATEL-VL53L8 board to my ESP32, and I am trying to run the basic ranging example, using ULD driver. When I run the example, I get VL53L8CX ULD Loading failed in the serial terminal. Trying to figure out what's wrong...
Resolved! VL53L5/VL53L8 Histogram, Multi-target Nearest and Strongest detection order, peak thresholding
I am experimenting with the VL53L5/VL53L8 sensors. For multi-target there are the options of target order of strongest and nearest. This is not a difficult concept. However, I am curious about the algorithm for detecting the peaks in the histogram. I...
Resolved! VL53L8CX_NB Multi-target mode - settings of 2 or more. RAM Usage and Compile
I will be testing out the VL53L8CX_NB, perhaps next week. I notice it has a setting for the number of targets detected per zone. My plan is to have 8x8 setting, so 64 zones. I note the firmware has setting of 1 target per zone. The current setting is...
Resolved! vl53l1cb: how to get the maximum distance
hello, I'm using a vl53l1cb satel board, but I'm not been able to get a reading greater than 4m (aprox).I'm using the vl53l1 zephyr RTOS driver, and I'm aware that the roi selection is different than the one of the UM2133, so I'm not selecting a spec...
