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...
I got a custom board made with these two ics and I tried to program the mcu. However, when facing FLASH and RAM size constrains I decided to remove certain parts of the library to make it fit(I removed crosstalk calibration since I don't have a cover...
The SATEL-VL53L8CX dev boards were all out of stock, so I picked up the LS53LX-SlL8 Light Saber Sensor VL53L8CX by Gilisymo for debugging before I build my own PCB. I am interfacing with the sensor via the Adafruit itsy bitsy nRF52840 (but have also ...
Hello, I noticed that using the X-CUBE-TOF Package with the STM32WL55JC Nucleo-Board has an issue with the I2C-Peripheral(I2C-2). This genrates the I2C code in the IDE. And the Sensor can be derived.while if I define the Sensor bus IO:The Generated c...
