#114425 - LCD Exerciser?
I was unable to find anyting specifically referring to a full-function exerciser for LCD modules here on 8052.COM.

Has anyone ever constructed a verifyer that tests HD44780-compatible LCD's to ensure that all its functions are available?

There are features most people don't use, but when starting out, one should be comfortable that the thing is capable of doing what's wanted, regardless of how few/many of the inherent capabilities are being used.

I particularly want to do that when I buy these things from surplus vendors, and I suspect I'm not alone.

What have you encountered?
