GPIO use of VL53L0X

Dear St, I'm using the VL53L0X to detect an object at a distance lower than 30cm. I need that the GPIO is activated (turned down to GND) if an object is present below that distance. If possible it would be better if the sensor is able to detect if th...

ROI for the VL53L1X

I'm looking for an example of reducing the ROI with the API for the VL53L1X. I prefer the API released by POLOLU, since I am working with an Arduino, but anything at this point will be greatly welcomed!  POLOLU directed me to your site. From the docu...

Device: VL53L1 Subject: VL53L1X_ULD API Question 1: How can I activate the 2V8-interface mode in the compact driver? Question 2: Should register 0x28 and register 0x29 both be written to ensure 2V8-mode?

Explanatory note: The "fat driver" has built in code to detect a "USE_I2C_2V8" flag. If detected, the software writes to register 0x2E. Though the register names for 0x2E and 0x2F suggest that both should be changed to get the interface mode wanted (...

VL53L1X sensor with ULD API stops sending data after some time

Our setup has 6 VL53L1X sensors connected via TCA9545A multiplexors to STM32F303 host. We started with STSW-IMG007 API, but later switched to STSW-IMG009 ULD API. First, the statement that ULD API has "only 4 files" is misleading. The code does not c...
