I am attempting to connect the satel-vl53l8a to the Nordic Semiconductor nRF5340 using the I2C protocol, but I am not receiving any acknowledgment (ACK). I have followed the wiring diagrams provided in this document: AN5945. Additionally, I have capt...
I'm having a bit of trouble talking to the VL53L5Cx... I'm appearing to download firmware ok, by all accolunts vl53l5cx_init() is returning with VL53L5CX_STATUS_OK and vl53l5cx_start_ranging() likewise. However, the response on the I2C bus to vl53l5c...
Hi, i am trying to use VL6180 to get an obstacle range.I'm using VL6180 APi to communicate with the device. Communication is ok, and consistent. Each register is written correctly.As show in ST examples I init the device and start a single shot readi...
Hello,i have managed to get the vl53l8cx to run and it returns correct measurements. with the occasional wrong distance. i wanted to take advantage of the "Status" values to throw out bad measurements. however my status prints are always 0.here is my...
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:...
