I just purchased a Pertelian x2040 LCD. It's an extenal, Hitachi HD44780 based 20x4 LCD with a USB interface (comes up as a usb-serial adapter, so there must be a parrallel-serial conversion in the unit itself). It's a great LCD, but the software that comes with it is really horrible and not as customisable as LCD Smartie. I tried using LCD Smartie 5.3.2 and 5.4b3 without success. I'm hoping you will be able to write the .dll so those of us with pertelians can use them with the new beta version. Info about the LCD can be found on Pertelian's website: http://pertelian.com/index.php and development documentation can be found here: http://pertelian.com/index.php?option=com_content&task=section&id=6&Itemid=33.
Thanks so much.
P.S. A demo on writing these display drivers would be awesome!
