gesture library in STSW-IMG035
Hello! I am an undergraduate student interested in gesture recognition based on ToF ranging sensors. How to use the gesture library to train a model for the STM32CubeMX project?Is there a tutorial? If possible, could you provide the complete project ...
VL53L3CX with Atmega328pb Xplained Mini
Hi,I am using the VL53L3CX distance sensor for a project and I am wondering if it's possible to create my own library functions. The MCU I am using is the ATmega328PB XPlained Mini from Microchip, which only has 32KB of flash memory. The API library ...
Resolved! VL53L4CX temperature update
Hi,I was wondering if someone can help me with temperature update on the VL53L4CX.According to UM2931 that describes the temperature update in paragraph 3.5 there is a dedicated function named VL53L4CD_Start_Temperature_Update() and can be used when...
Resolved! VL53L5CX Power Consumption
Hello @John E KVAM ,Table 14 in the datasheet shows power consumption in Autonomous as going as low as 4.5 mW, but is this only the AVDD power? or total device power? Because I do measure low power draw at those levels, but only on the AVDD pin (and ...
VL53L8 smalles FoV
Hi,I have a project for which I need to measure a tank level of tanks with a maximum depth of 3 meters. The challenging part is that many tanks have filling tubes with an inner diameter of 50mm but a length of 1000mm worst case. I have made this draw...
Resolved! Is the VL53L5CX ToF a good choice, considering all the Time-of-Flight sensors family realized by ST for detecting obstacles below the floor level such as holes or stairs?
Hi community, I would like to understand if the VL53L5CX is a good choice to develop an application to detect holes and stairs. I decided to study them since I was impressed by these things:The FoV of 45 ° horizontally or vertically;The granularity o...
Resolved! maximum temperature (while not operational) of VL53L0X ToF sensor
Hi everyone, can you provide information on the highest temperature and ambient pressure the VL53L0X Time of Flight (ToF) ranging sensor can handle without being damaged? Note: this is not during operation of the sensor (operating temperature is give...
Resolved! VL53L8CH Example code to configure for histogram and get data
I want to use the VL53L8CH in histogram mode to distinguish between multiple reflective surfaces. I found a c-driver package in STSW-IMG043, but no useful example how to initialize the sensor and get data out (over I2C).What I'am looking for:1) initi...
VL53L5CX Bouncing Issue
Hello,Even in the SparkFun product introduction video (2.45-3.00 min), the representative presentation shows there is some bouncing in the sensor reading. I have also experienced the same bouncing issue. How can we deal with this problem? Regards,Fe...
