<![CDATA[Core2 Port I2C Not Working]]>I have a grey core and have used the TOF sensor with success, utilizing UI-FLOW. I just got a Core2 and burned UI-Flow into it. When I attach the TOF sensor to port A it appears to not be able to be read on the I2C bus. Any suggestions?
Thanks

Felix thanks for the suggestion. You were absolutely correct version 1.7.0 resolved the problem.

Now in 1.7.1.1 this problem was fixed.

please checkout this post. It looks like M5Core2 UIFlow firmware 1.7.1 is broken in that respect, but 1.7.0 seems to work.

Thanks
