Hello,We are researching the feasibility of a new product and have some questions regarding STMicro's TOF sensors. At this time we are narrowing on the VL53L4CX, but I am sure these questions apply to most of these sensors. The product is detecting d...
Hi,When I get the data returned by VL53L4CX, I have two problems.1:About"VL53LX_get_device_results()"The API function "VL53LX_get_device_results()" takes a lot of time. My MCU is 32MHZ and the operation of this function takes me 13ms. Is this time ac...
The Ultra Light Driver (STSW-IMG023) init function vl53l5cx_init() fails in this section :/* Get offset NVM data and store them into the offset buffer */ status |= WrMulti(&(p_dev->platform), 0x2fd8, (uint8_t*)VL53L5CX_GET_NVM_CMD, sizeof(VL53...
Hi there,I was wondering if the memory used to save the values in the device registers for the VL6180X sensor are volatile or non-volatile. This would affect how the sensors behaves during a power cycle. Could someone clarify this for me if possible?...
When I place an object near the sensor, it shows the reading between 40 - 50mm. How to perform the calibration of this sensor to accumulate accurate reading from the sensor. I have attached the code that I have uploaded.
Hi, I am currently actively debugging and working with the sensor and it shows correct measurement data when i set the profile to 'Long range' example (settings from the 'um2039' User manual). however the sensor response for RangeDMaxMilliMeter:...
Good Morning,I am interested in using the VL53L1X sensor for my application. Before proceeding with the implementation, I would like to gather some information regarding the optical interferences that may affect the sensor's performance.Firstly, I am...
I use a VL53l1X looking trough a oil layer of ca. 20 mm. When getting measured distance 3 times with GetResult(), it returns (example):Status = 0, dist = 11, Ambient = 16, Signal = 20936, #ofSpads = 6Status = 0, dist = 19, Ambient = 8, Signal = 18104...
Hi STM Team,We are using VL53L0CXV0DH Sensor for our Object Detection Application in Medical Field. The Sensor is working fine, but after 1 month of time the dust in the environment covers the sensor's LED part, so, the dust was affected the overall ...
Hello all,I'm looking for a rough estimation of required RAM and FLASH for the VL53L8CLD Driver and the VL53L8CX ULD Driver together with STSW-IMG035 Gesture Layers. The GestureEVK_UM.pdf (v1.5.0) shows on page 49 some indication for the artifacts...
