Well, here's a link to another "error":
Look, I didn't ask where SDA/SCL were - I asked why the docs all said it was in the wrong place. Perhaps there are variants between models, or between European/American/Asian versions. I do know that A4/A5 doesn't work for the clones I'm using, and D4/D5 does. And I'm using the standard Adafruit library.
I've written SCADA programs for nuclear power plants, smelters, rolling mills, White Sands, and a space shuttle emulator for NASA. So I'm not some newbie.
BTW, the shuttle was the most fun. I got to sit in a mock up cockpit and test my software :-).
I see no need to try and convince all you "experts" of anything, so I'm dropping this topic now. Have fun.
