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...
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...
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...
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 ...
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...
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...
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...
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...
Hello,I am developing a system using VL53L1X.I have read UM2356 (VL53L1X API user manual).I would like to know the background of the recommended conditions for the offset calibration procedure Chart distance: 140mm.Is it a peculiar point that Chart d...
In my product I use the VL53L1X sensor for more than 2 years. But the last 50 sensors I bought had a problem. The measurement is too incorrect and the peak_signal_count_rate_MCPS and ambient_count_rate_MCPS parameters are too low. I purchased sensors...
