I think those two values are for HDR(High Dynamic Range). Am I right?1. If so, is it possible to use the same value for VL53L0X_VCSEL_PERIOD_PRE_RANGE and VL53L0X_VCSEL_PERIOD_FINAL_RANGE?The amplitude(brightness) of the reflective sheet gradually l...
I have a simple ranging project generated by CubeMX using X-Cube-TOF1 v2.0.0. The host is Nucleo-L452.Initialization of the VL53L2CX appears to work without errors, however when the "VL53LX_run_device_test" function runs it fails after the timeout, r...
In vl53l5cx_init, the sensor sends the `VL53L5CX_FIRMWARE` data to the sensor. This means the main application MCU needs to store the ~80kB+ in its data. Can this be modified so the firmware is downloaded only a single time, so there is less memory o...
Hi, I am trying to use the vl53l5cx_set_i2c_address() function in order to change the i2c address, but it keeps returning -2, or VL53L5CX_COMMS_ERROR from the following line in vl53l5cx_set_i2c_address(): status |= WrByte(&(p_dev->platform), 0x7fff, ...
Hi, because there is almost no information about Motion Indicator from the existing docus, could you pls explain how does it work. And what does it aim to be used?Thanks,Best regards,Wayne
Hello,I want to evaluate VL53L3 / VL53L5 devices. The end application will be behind glass with a distance of ~20-30mm between sensor and glass. I've Nucleo and Satellite boards for the two sensor types and setup a corresponding test environment wher...
Hi,we are planning to use 3x VL6180 on same PCB to accurately (1mm) measure distances in a dark container. Our required range of measurement is 2 to 80mm. So far we got to around 0.5mm accuracy, but the problem is repeatability. Exactly what i mean i...
I have a design ready to go but it needs to work for 3 years using 4xAA alkaline batteries. My company has planned 500K pcs/yr. I would really appreciate any help with this.Thanks,AL
I am using the exaple1 ranging basic (VL53L5CX_ULD API ) on microcontroller nrf52840.during vl53l5cx_init(&Dev) we get stuck on "do while loop" in the below Function (vl53l5cx_poll_for_answer() line number 304 ). I'm include the I2C driver (Read&Writ...
Hello,the VL53L5CX is a really nice senor. I have done some measurements using the Windows GUI and was impressed, so I wanted to write a driver for the sensor and do some further evaluation.I then tried to initialize the sensor using the ULD-API and ...
