In this test all I have done is sent out the ASCII Characters T, E, S and T and in the main program loop I am sending a HIGH, then a LOW to the BL (Blanking) pin every 500 milliseconds. This simply makes the display go blank and then 500ms later again display what is stored in its RAM.
The unit is really easy to program. In fact, I had to start from scratch and work it out from the datasheet as I couldn't find any code examples for the Arduino online to test it with. It does however use a lot of digital outputs. In this test I have used 12 digital outs from the Arduino. The next stage is to use 2 very cheap Shift Registers to send data to the module and hence reduce the outputs required to just 3.
This is a similar unit to one used by Tom Igoe in the recent MAKE TV: episode where he was demonstrating the Arduino Mega - blog.makezine.com/archive/2009/04/arduino_mega_video_with_tom_igoe.html?CMP=OTC-0D6B48984890
