lc709203f_simpletest.py error on CLUE

Post by jesse_m »

Hi all,

I recently received a LC709203F breakout, but when I try to run lc709203f_simpletest.py, I get a "CRC failure on reading word."

Any ideas what might be the problem?

Thanks in advance!

Is the LiPo charged? The LC709203F gets powered by the battery, so needs it to have adequate power.

Yep. Just tried with a freshly charged LiPo - same result.

FWIW, I've run several programs on this CLUE. It was only when I added the LC709203F that I started having issues.

Can you link to the specific LiPo batter being used.

Thanks. That should be just fine.

I think you might be running into this same issue:
https://github.com/adafruit/Adafruit_Ci ... F/issues/3

Looks there's been some work on it, but may not be fully resolved yet.

Just to check - are you using the latest releases of everything? The LC709203F library, CircuitPython firmware, etc?

Aparently not! I updated all the libraries and the .uf2 (v7.3.3) and now it's not crashing anymore.

It's able to read the LC709203F about half the time (the other half I'm getting "retry reads"). Is this expected? Any way to increase the % success?

Please disregard my previous question. I was able to get it working. Thanks so much for your help!

OK, cool. Hopefully just updating was all that was needed. If it starts happening again, just respond back here and we'll continue looking at things.
