Hi All,

I have a sensor using i2c communication attached to an UNO which was working flawlessly.
After updating to Arduino IDE 1.8.10 I have been experiencing issues when working with i2c:

1. Unable to establish i2c communication with sensor. When using the standard
if (!gyro.begin()) it always gives an error

2. Serial communication stops working when the SDA/SCL or even A4 or A5 pins or plugged in. This is the case when the sensor is powered and also not powered.... weird.

Can someone please help me? Is this an issue regarding the update or the IDE or my hardware...

Thanks!

1.8.10 has seen a lot of different issues.
General consensus is to try rolling back to 1.8.9 at least.

Additional clean up instructions attached if you go that route.

Additionally could you take a few moments to Learn How To Use The Forum.
It will help you get the best out of the forum in the future.

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

Hi,
I went to 1.8.9 and the same issue still exists...
I then went back to 1.8.6 where the sensor has worked before and I'm still experiencing the issue.

Are there other solutions?
Thanks.
