Resolved! VL53L5CX ULD and device power consumption
I see that the VL53L5CX sensor has two voltage supply alternatives, both for the digital part (IOVDD) and the analog part (AVDD). I am also observing that starting from version 1.3.3 of the ULD driver, we have a function called vl53l5cx_disable_in...
Resolved! VL6180X trouble picking out the best target object
Hello all,I am confused on some test results that we performed while gauging the VL6180X's performance and am seeking some advice. We are testing various materials with the intention of using the best performing one for the target object in our appli...
Resolved! "vl53l0x_ContinuousRanging_Example", it cannot be measured.
When executing "vl53l0x_SingleRanging_Example" or "vl53l0x_SingleRanging_High_Accuracy_Example", the distance can be measured correctly, but when executing "vl53l0x_ContinuousRanging_Example", it cannot be measured.Is there somewhere I can check?Belo...
Resolved! More questions about Size of Zones and FoV
I have a very simple question concerning the size of the zones and the field of view for (for example) the VL53L8CX sensor. which has a diagonal FoV of 65 degrees. Can anyone provide a simple answer to this question:If the sensor is 1 meter from the ...
Resolved! Which API should vl6180 use?
HI, i am studying how to controll vl6180 with a custom board which MCU is STM32L452CCU6. At the beginning , i tried to avoid implementing the api by changing register directly using i2c, however,0x018 is set to 0x2 or 0x0 both did not generate the ra...
Resolved! About overcome indirect sunlight problem with vl6180X/V1?
Hey, I am using a customize board (MCU:STM32L452CCU6) to develop a gate checker with vl6180/V1 and cover glass with IR filter. Implemented a default value and setting ,the sensor and code works fine indoor. But in the outdoor condition under the sunl...
Resolved! VL53L5CX gesture library older versions
Hi, I would like to download older versions of the VL53L5CX gesture library (to be exact the 1.7 and 1.8 versions for cortex M4), but I'm only allowed to download the latest one (1.9). Is there any possibility to download these two versions?Regards.S...
Resolved! How do I handle 8 bit I2C address when I port ST32 driver to 8 bit device driver?
Dear ST Engineers,I am planning to port this device driver to another 8 bit MCU:https://www.st.com/en/embedded-software/stsw-img023.htmlMy 8 bit MCU has I2C slave address range from 0x00 to 0x7F.However, hint of that ST driver code insists on using u...
