Garmin LIDAR-Lite v4 LED - Distance Measurement Sensor (Qwiic)

Sensors Distance

I purchased one of these, got everything tested and ultimately had my prototype. I mounted everything, tested, and everything worked.

A few weeks later, I went back to the project and the serial port displays

“Device did not acknowledge! Freezing.”

no code change on my part, but, I used the demo code and it does the same thing. The Arduino IDE did update from 1.1.4 to 1.2.4, but downgrading doesn’t appear to make it work. I purchased a new Sensor, new Qwiic cable, and even using the demo code, I get the same message on both units.

When plugged into the Qwiic controller, I thought there was a red light visible on the board in the sensor, but I don’t recall if that was only visible after it initialized or not.

How do I troubleshoot this further?

I tried two other Qwiic boards I purchased and they don’t appear to work. I ordered another redboard that I should get in a day. This might be resolved with that.

It sounds like the Redboard is the issue - try re-installing the drivers that it uses by following this https://learn.sparkfun.com/tutorials/ho … 1622745974

If that doesn’t work, the new board hopefully will :slight_smile:

(if not, we can go form there)

Both prior and after following the tutorial, I am able to write code that exercises the built in LED, but nothing attached to the qwiic port is recognized. I’ll update this after I receive the new redboard.

Replacement Redboard fixed it.
