I've just been handed a short term (ie: clients urgent job) to connect a Lascar
DMX973B display to an existing 18F4550 (??) system via SPI, as there are
insufficient pins for 8 bit operation.

I am not familiar with this display aside from the fact that it uses the SED1530
controller, is bit mapped and the client needs it up and running is less than a
week, mixed character and graphics.

Rather than reinventing the wheel, so to speak, are there some library routines,
PICBasicPro or CCS, that permits easy turnkey implementation ?? Even a
controller chip would be great.

Any suggestions would be most welcome.

Regards,

Antonio Benci.

Try taking a look at www.geocities.com/g13685/DMX_973_973B.html
It seems to have code to run the display:

"// Epson SED1530 Constants from datasheet"

It is in HiTech but shouldn't be too much trouble to port over to CCS.
Probably easier than from scratch.

I believe the Microchip Graphics code handles this chip. It comes with the
USB framework code, and depending on exactly what speed you want, could
probably go in an 18F with larger memory, to make an SPI interface to the
display.
