VL53L8CX Power up sequence

Hi John, Could please confirm if the slew rate requirement of VL53L8CX is satisfied in the EVM X-NUCLEO-53L8A1?  We're considering to use TI's TLV751180330PDSQR to power up the VL53L8CX sensor. But the TLV751180330PDSQR supports 11mV/µS approx. Also,...

Resolved! VL53L4CD Calibration - Measurement Timing Budget

Hello ! I am calibrating a VL53L4CD ToF sensor. Is it suggested to set a large timing budget (e.g. 200 ms) for the offset and crosstalk calibrations' distance measurement process? In the distance measurement examples, the timing budget is set to 10 m...

Resolved! VL53L8CH More CNH Bins for One CNH

Hello,I am using the 53L8A1A to evaluate the VL53L8CH with the MZAI_EVK_v1.0.1 software. For my application, I need high CNH resolution for as long a histogram as possible, but for only one histogram. Because of that, I aggregated down to one row and...

Resolved! can't get VL53l4CX board to work

Hi,i've been posting here a few times to get a VL53L4CX to work. I've had success so far, but the latest iteration of my little PCB is really giving me troubles.When i apply power to my board (via an esp board) it stops working (the esp32 board). It ...

Resolved! VL53L8CH Signal Width

I am guessing there is nothing that can be done about this, but I thought I'd post about it. I got the VL53L8CH because it has better bin resolution than the VL53L3CX, which I hoped to use to distinguish between objects at different ranges that are c...

Resolved! VL53L4CX RefSPAD caliberation - no target?

Hi,i'm playing around with the VL53L4CX after putting it on my own pcb (yay).The user guide states that for the SPAD caliberation, NO target should be placed. The crosstalk requires a 600mm target.Do i understand correctly that the SPAD caliberation ...

VL53L1X Custom Board Issues

Hello! I've designed a custom PCB very similar to other breakout boards on the market, because there are additional components I want to fit in a small package alongside the VL53L1X sensor. When testing my PCB, the sensor does not initialize. I've be...

Wake up microcontroller using GPIO of VL53L0X

HI folks.I would like to wake up my ESP8266 using an interrupt from the VL53L0X sensor.I have configured the sensor to use both threshold detection and to trigger an interrupt. I tested whether the interrupt is being triggered, and it is— the GPIO pi...
