1.8" Color LCD 557x234 resolution, will it work with the Prop ?

I just bought some of these hoping to use them with the propeller.
Does it look like there is a chance ?
Anyone want to write a driver in exchange for a module ?

I don't think there is any driver. Just the LCD.

I have a couple odds and ends of LCD displays laying around but haven't written any drivers for them. I don't have any displays like you posted Bean. Ihave a monochrome driver I created for an LCD I used in a recent product design. When using a color LCD, the hard part is storage of screen data. All the bits and bytes for RGB add up. Not to derail this thread, but any thoughts how to deal with this?
Judging from the data sheet glance I took, I think a carrier board will have to be made to use the LCD. There appears to be a fair amount of supporting circuitry needed to be sure the right voltages are applied. It also appears that a video signal can be applied to the display. VGA or composite? It needs more studying. I am not seeing an SPI or paraller input for R data, G data, B data, H sync, V sync, etc like I am use to seeing on the many other datasheets I have reviewed for LCDs.

One little spark of imagination is all it takes for an idea to explode
I have to give it a shot, because I have some 640x480 (b/w) displays I want to use, but they will need more ram...
So...Is anyone interested in taking a wack at a driver ? I'll send out some samples when I get the adapters made.
Because of the limited RAM in the propeller, even an 8 color driver would be great.
Let me know if you think you have a good idea how write the driver. I'm assuming it's similar to a VGA monitor ???

Any brave souls want to take a stab at a driver ? I'll send you one.

I would like to offer $500 to the first person that gets one of these working with the propeller.
The only datasheets I have is the one at the top of this thread.
I can supply a breakout board so you can connect it to a breadboard.
If you are interested, just send me a private message.

I would consider using the support chip, but I cannot find a source or even a datasheet for them.
Even if I could find a datasheet for the support chips that showed what the output signals from the chip look like, that would be a big help.
