Read data from LCD (4-bit mode)

floresta:
The search function is cleverly concealed at the upper right. It's green on green (both the same shade of green) and not immediately apparent.

Let me be more specific.
While the Arduino forum does have a "search" capability, it is not handled internally by the forum s/w, like every other forum out there - standard forum s/w packages include a real search capability.
Yeah you can do searches using that little search function, but it sucks since it is based on a google search and hence has no knowledge of forum attributes.
The forum used to have a real search back when it ran standard forum s/w, but then
a few years ago, the Arduino team, decided that they would abandon the standard off the shelf forum s/w and modify it with their changes and "enhancements".
For MANY months the forum was very broken, and ever since that time, the search capability was removed and it was turned into a google search.
This makes finding things more difficult since there are many things that you simply cannot do with a google search that you can with a real forum search.

To this day I have no idea why the Arduino team decided to spend their resources re-writing forum code that seems to be working ok for everyone else.
