Adafruit ESP32-S2 Feather using WipperSnapper no longer detects on board LC709203F battery monitor over I2C at address 0x0b about adafruit_wippersnapper_arduino HOT 4 CLOSED

Yep, at first glance I believe this is a purely cosmetic issue in the web where we're accidentally dropping a leading zero before building the full hex string. Making a note to chase this down soon.

Thanks for the thorough report and screenshots, @khpacific!

@khpacific Glad the issue was fixable on your end!

Though the address like in your screenshot of the component creation still shows as 0xb. I'm assuming having a 0 between x and b is not important for the address?

Is this an edge case with the web form showing 0xb? The component definition lists 0x0B as the address: https://github.com/adafruit/Wippersnapper_Components/blob/main/components/i2c/lc709203f/definition.json#L4

@khpacific Hi, I tested this with an Adafruit ESP32-S2 Feather running Beta 67 and did not have issues with the I2C scan or new component form for the LC709203F.

Addition: I realize this component was recently discontinued and replaced but does that also mean support was removed for it?

We did not discontinue support for it within WipperSnapper.

I'm not sure if this is a wipper or IO issue as the other board I have has not been updated from Beta.59 and hasn't been touched in months but still shows the same address issue for the LC709203F component that used to work.

It actually might be an issue with your specific Feather board. Did you purchase it recently? As of June 14, 2023 - We have changed the battery monitor chip from the now-discontinued LC709203 to the MAX17048.

Hi @brentru,
Edit: Thanks for the answers
It was purchased on 1/23/23. But seeing your screenshot of the scan made me realize I hadn't tried unplugging the AHT20, I had only unplugged the battery for testing. After removing the battery and AHT20 then resetting the board, the LC709203F appeared in the scan results. I added back the AHT20, reset, still there. Added back the battery, reset, still there. With the battery and the sensor plugged I created the component again and this time it was found and accepted.

The problem seems to be resolved as it's available and reporting regardless of the other components now. Though the address like in your screenshot of the component creation still shows as 0xb. I'm assuming having a 0 between x and b is not important for the address?
