Problem with multi-channel water level expansion

Post by dedvalson »

I have the 4 channel water level expansion on my system, it has been there for over a year, probably close to 2.

It has had a problem off and on that seems to be getting worse recently. Occasionally all 4 channels will read 0%. This will usually happen at a random time and it will last anywhere from a few seconds to as long as 20 minutes. Then suddenly everything comes back to normal.

Any suggestions?

Strange.
Did you try using a different port on the hub?
Does it cause a bus lock when they report zeros?

It does not cause a bus lock, all the other devices keep working fine.

I will try another hub port.

i had this too. To mitigate, i put code in there to ignore the '0' water level reading. Also, i think changing the usb port helped a bit.

what version of the libraries? I know there have been improvements with the water level functionality in the latest.
