DX160 128x64 pixel LCD Display Driver

[rfryar]

I have started development of a DX160 Display driver. This LCD display is a 128x64 pixel display or 8x21 characters.

The unique features of this display is that it allows pixel access to every pixel in the display!

Now I have the basics completed, standard text, basic positioning commands, etc.

I started to work on the custom characters but here is the crux, at the moment I have no way to define custom characters and output them as a "character". So to get around this my driver will currently write each custom character pixel by pixel as it encounters them. It works but is too slow. It takes ~40ms per custom character at the moment.

But that aside I have a few questions that I hope can be cleared up about LCD Smartie itself.

1) How can I get it to understand other display sizes? More rows or columns other than 4x20?

2) Has there been other displays written that allow more than 8 custom characters or direct pixel access?

Here is the work in progress site: http://lcdsmartie.fryar.org/index.php

1) You would be better suited if you set lcdsmartie for 4x40 and then in the driver cut the rows at 20 characters, that way you will only loose 8 characters at the end of the 8 physical rows.
This is the only way for now.

2) No and no. I built myself a graphical display with 16x40 characters, it supports 256 custom characters but lcdsmartie can make use of only 8.
This is because it was originally written for HD44780 displays.

Good luck!

The initial driver has been released as well as a special plug-in that will allow the use of 16 extra custom characters in all LCD Smartie DLLs on this display.

Check out either my LCD site or the Plug-in Announcements page for more details.
