I'm not sure what you mean by withholding information as I have given you basically all that I have.
The datasheet I mention holds no timing information nor similar data and the pinouts declarations are the same as the normal HD44780 based displays barring, as I stated, the additional enable pin at position 15.
There is a possibility that the Batron is driven by a Samsung KS0073 driver chip however I can't confirm that and Batron won't respond to requests for information.
However if you think it will help then I suggest you try going to http://www.datasheetarchive.com/dlmain/Datasheets-315/513304.pdf
and downloading and reading that even though it's a single sheet with, as I say, no salient timing information
I have tried a partial rewrite of a version of LiquidCrystalFast. h also with no success.
As a point of interest, so far I have discovered many people having problems interfacing Batron LCDs to various processors so at least I'm not unique.
