Yo, Rayman...

Mike B.

Just noticed on your web site a ExpressPCB board layout for the Mini-Marx controller for the Sparkfun "Huge LCD display".· Does it work?· Is the board available from you?· More info??· Looking to get a rather large LCD working on my project but the serial backpack SparkFun sells has some pretty bad reviews.

· Tell me more Ray.

That was a board I made to drive Sparkfun's "huge" LCD display. It works very nicely.
I don't sell it, buy you can have ExpressPCB make them for ~$50. Or, $75 with soldermask and silkscreen...

Thanks Ray.· Do you have any doc's on it other than the PCB layout??· Is it serial??

As I recall, it's an 8-bit parallel interface... I think I've posted a driver and test code for it on my website...

I'm using the big LDC display and I'm happy with it.
Check Rayman's driver, it explains a lot, end is well documented.
Check also the datasheet.
I'm using the dsiplay with the protoboard, and while it is reported to work without limiting resistors, I still use 2.2k resisors between all the pins.
I changed a little bit the code, in order to use also propeller ROM font, and thanks to Rayman's, I was able to post it ot obex. The differences are minimal, but you can save the graphics part in a buffer before sending it to the LCD, and you can have big fonts, also in inverted field (this one is good, if coupled with a little bit of backlight, if you use it outdoor).

Only downside the display is pin hungry.
You need 8+4 (data + control) pins, and another one if you want to control back light. Consider also the display is not blazing fast. Refreshing all the screen takes anout half a second.

Edit:
.. double posted. Sorry
