Wire.h generating error messages. Seems to affect my project hardware. #7
Description
TLDR
"Verify" in the Arduino IDE generates the error messages shown below. The code I've written seems to work when the relay is OFF but when the relay turns ON, serial LCD display looks like it is power cycling. Did not do that in April.
Version Details
Am using Arduino Uno (Sparkfun RedBoard actually) with a COM-15093 SparkFun Qwiic Single Relay that uses the SparkFun Qwiic Relay Arduino Library version 1.2.0.
Have a 1 amp 12 volt DC power supply plugged into the RedBoard so everything should have sufficient power. (With the relay OFF everything works as designed and the serial display stays on and updates the display with power just coming from the USB cable.)
Last time I verified this code was April 2023. I switched from an Intel Mac to an M2 Mac and put this aside for months to focus on other stuff. It's now September 2023 and I'm returning to this code. Updated the Arduino IDE to 2.2.1. Updated all the other libraries I had installed in April 2023. Re-uploaded the code into the Uno. Turns out none of the SparkFun accessory board libraries have changed.
When I do "Verify" in the IDE I get these error messages and I'm not sure what they mean, why I'm getting them, and whether they are causing the problems (I assume so since changing the relay from OFF to ON causes the problems.)
Hardware
Everything is connected via Qwiic cables from SparkFun. This is the order in which they are connected:

DEV-15164 SparkFun Qwiic OpenLog
SEN-16467 SparkFun Humidity Sensor Breakout - SHTC3 (Qwiic)
COM-15093 SparkFun Qwiic Single Relay

Help Please
Anyone have any thoughts on if fixing the errors in Wire.h will fix the power cycling of the Serial LCD display?
