Imaging (sensors)

Does the VL53L5CX need to download firmware every time?

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...

Changing VL53L5CX i2c address?

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, ...

Measuring short ranges with VL6180

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 need to detect an object up to a distance of 8 inches 3 times per second with a power budget of 0.1 mW average. I am using a VL53L0X and I have been trying to lower the power consumption without much success. Can somebody help me with this?

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 have a problem on VL53L5CX_ULD API (exaple1 ranging basic) during the function vl53l5cx_init(&Dev).

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...

X-Nucleo 53L5A1 works fine with Windows GUI, but does not even init / is not alive using API

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 ...
