The usage of the display module is quite straight forward; just plug the serial adapter to the display and upload your piece of software or send serial commands to control it.
There are two different firmwares for the module; the first one is a serial platform firmware (the module came with this loaded to it) and the second firmware is for running 4DGL programs in the module. Both of these firmwares can be found via the product page and they are changed with the PmmC Loader, which is very easy to use; just select the correct firmware file, choose your COM port and click Load.
PmmC Loader
4DGL Platform
4DGL is a graphics oriented programming language that is made for PICASO and GOLDELOX processors to be run on their own on the modules. 4DGL has a good library of different graphics, text and file system functions (and touch panel related functions for displays with Picaso and touch panel) for easy and fast code development. If you have some coding experience with C, Java, Basic, Pascal etc, you shouldn't have problems with 4DGL. For 4DGL development you'll need 4DGL Workshop from 4D System's website.
More in-depth info, downloads and manuals are available at 4DGL developers corner:

Starfield effect made with 4DGL
Well, this doesn't really get everything out from the display, but it was mainly a coding practice for myself to learn a bit of 4DGL's syntax. The code is mostly a C to 4DGL conversion of the starfield code found from The Demo Effects Collection. For this example the 4DGL platform firmware has to be loaded to the module.
The code:
