Hello.I am working with a vl53l1x sensor and i need to know if this sensor report a distance when the target is not detected and the measurement is valid, like the vl53l3cx sensor that report back 8191. Does this sensor report the same number or othe...
Hello !I'm working on the VL53L5CX sensor with a Nucleo L432KC.Using the ST example, and after succeeded the initialization of the VL53L5CX, the sensor's data are never ready. In the following function, the p_dev->temp_buffer[1:4] are all equals to 0...
"2.1 Software Interface" in the VL53L5CX datasheet states that the driver (C code, reference Linux® driver) is delivered.How can I get this driver?Please let me know if there is a download URL for the source code.
I just purchased the VL53L5CX-SATEL Breakout Boards for VL53L5CXhttps://estore.st.com/en/vl53l5cx-satel-cpn.htmland i have been trying unsuccessfully to get it to work with an Arduino Mega 2560. Does anyone know if it is possible to get it working wi...
Hi:I'm testing the VL53L4CX and I'm experiencing some problems:1. When an object is within 3.5m and there's a wall 5 metres away, sometimes the returned distance alternates between two distances.2. When there is a mirror within 3.5m, VL53L4CX sometim...
I have been testing with the VL53L1X TOF sensor and am curious on the durability of the sensor in rugged environments. Such places would look like an industrial environment where vibration and impacts in inevitable. The sensor PCB would be potted and...
Hello, I'm trying to use a ToF-Sensor to track the distance of metal parts (sheets, cog wheels etc.) usually in the range of 0-60cm. The thing is that I am only interested in the distance of the surface that is directly below the sensor, the center o...
In the ULD driver for the VL53L8 is the file vl53lmz_api.c. In line 354 to 364, the firmware is loaded in pieces of 0x8000 bytes:My microcontroller has not enough ram to handle such big blocks, so I have to load the firmware in smaller pieces. But fo...
As shown in the figure is a ball, the depth difference of one pixel is less than 3.7mm. But as shown in the histogram, the depth difference is more than 15mm. I would like to know if this is caused by noise or some other reasons?
Hello,I noticed a difference of ranging time on VL53L4CX in function of target presence or not.My parameters : AVG = 3 ; DTIM = 33 ms ; INTERMEASUREMENT = 100msCurrent measurements : Without target : pulse width = 38 ms ≈ DTIMWith target : pulse widt...
