Colorduino and IDE Version 1.8.2

My programming of the Arduino controlling Colorduinos using I2C was going just fine using IDE 1.7.11. However I installed the new version 1.8.2 and now I have problems.

The main one is that my sketches pass all the compiler tests and download to my Arduino but the Colorduinos don't work. This is with sketches that worked just fine with the old version.

You have to modify wire.h and twi.h to make the I2C work. There are more places where these files are held in 1.8.2 than 1.7.11 but I think I have found then all and edited them but I may have missed one somewhere.

I can, of course, go back to 1.7.11 but I would prefer getting 1.8.2 to work.

Any ideas?

What are the new features of 1.8.2 that you need or want that are keeping you from rolling back?

No particular features. The automatic set up of the USB port was good.

I guess I will do a rollback. I am using Win 10 by the way.

But do remember the 1.7.x was the strange Arduino.org branch. People here like to not touch that branch.

And what exactly did you need to edit in wire.h?
