  NEWS:

  It's Alive! My concept for this sensor now has fully working hardware and driver code.

  With a single COG driving it we can achieve:

  • Full 180° frame unloads 4x4 resolution at 12 Hz (12 full frames every second) - A new frame every 83 mSec.!
  • Full 180° frame unloads 8x8 resolution at 7 Hz (7 full frames every second) - A new frame every 143 mSec.!

  The full description of my turning on the hardware and verifying operation is at TURN-ON 180Degr FOV Sensor page in my repo.

  It’s a very interesting sensor.
  Not sure I get it 100%, but looks like an array of laser pings.
  Should be great for robots.

  Hi Stephen,

  lot of verbiage there but what about actual range/accuracy performance. Did I miss it?

  I have been looking at this type of sensor but I need professional, rugged packaging. I'm thinking a Prop-1 and six of the following in serial mode:

  @Mickster that detail is found in the sensor data sheets at the repo and at STMicro's website.

  Hi Craig,

  On this page:

  • The single VL53L5CX object page
  • Look in Table of Contents (Additional Pages):
    • You'll find all useful datasheets such as VL53L5CX datasheet

  NEWS:

  The documentation of the drivers has been updated at the P2-VL53L5CX-time-of-flight-driver repository.

  Of note are the documents describing the three individual P2 objects offered by the project:

  1. The quad TOF sensor 180° FOV P2 object
  2. The VL53L5CX TOF sensor P2 object
  3. and The PCF8575 16-bit I/O expander for I2C P2 object

  ... as you can pick and choose from these to use in your own projects.
