That is 547ns max. I can drive 16bit color bitmap with 64 sprites. Cool

24 bit LCD Breakout Board coming soon. $21.99 has backlight driver and touch sensitive decoder.

I know these displays were not intended for "PC" use, but is it possible to hook these displays up to a computer via RGB? I would guess I would need a VGA to Digital RGB converter.

For that matter I would love Composite! :-D That would save on wires for sure!

People have been asking for the 6-bit photo code... Unfortunately, it's not in very good shape yet.

It shows a fullscreen 6-bit photo directly from a file on the SD card. Currently, it just barely works and is unstable in x and y and has very low refresh rate...

But, here's a first look at it anyway. Also, here's the Windows App I use to create the data files for the SD card.

Also, here's another screen shot. Note that the camera photo looks much better than it does in real life. Also, I've done some Photoshop error diffusion magic to optimize the result...

looks cool. pretty impressive considering it is only 6 bit colour. I am working on a 16bit single cog version but I am using 4 latches and a RAM module to make that happen.

24 bit LCD Breakout Board coming soon. $21.99 has backlight driver and touch sensitive decoder.

Hehe I like the image you're doing the demo with :)

Looks great Rayman, I really need to get a break out board setup now.

Ran into a problem with 6-bit mode, seems VGA driver is too fast to read HUB ram the way I want, even will PLL turned all the way down to 500kHz...

But, I'm looking at it closer now and I think if I just shift all the VSCL constants to the left a bit or two or three, I can slow the driver down enough to make this part work...

Still need to see if I can make it slow enough for the SD part...

If all goes well, we'll be able to mix 6-bit from SD image tiles with regular ROM font tiles. This way we don't have to have full screen images...

Also, if this all works out then full-screen 6-bit video should also be possible (albeit with a very low frame rate)...

Why not bitbang the output then. That is how I am going to do 16 bit color

That's how my demo does it, but I didn't see a clear path towards higher refresh rate and also adding in ROM font...

VSCL wouldn't work because of the pixelclock...

But, I've played some other games and gotten the framerate up to maybe 6 or so, very close to passable...

Here's the latest version (the lcars screen is isn't too bad, but the flicker is still very noticeable in Jean Luc...).

My display is running great. I've seen the graphics demo. Would it be possible to have a graphics driver that uses all of the 480x272 pixels? Even if it has to be one bit per pixel mode?

of course it is possible someone just needs to right one.

You can do Graphics full screen, but only not double buffered... For example, the drawing area in the "PSB Paint!" program could probably be extended to full screen...

I just got the Propeller Platform version of the breakout board in the mail on Saturday, and it's now available on Gadget Gangster. Here's the requisite photo:

Nick, I'd love to buy some of these breakout boards (I just ordered a Propeller Platform board from you). Any idea when these will be available again?

So would I! I'm pretty sure Ray will send me more, but I don't have a delivery date. But if you enter your email on the project page (here), I'll let you know when they're in stock.

I've got a few more ready to ship, but I'm putting together some more PSM units that I want to put in the box too...

Can you reserve one of these for me Rayman or Nick please?

I got some of Ray's LCD's today shipped to Sweden. I was mighty surprised about how easy this went (except for my reversed order for all the VGA pins at first

), and not to mention the power of the back-light, wow! In Sweden I've barely got a cheese-sandwich for $5, really happy with the screens, they look brand new as well. The three demos was a real time saver as well, thx man, hope you get something for all your effort to make this happen Ray, this Propeller community thing really makes one remember what was so fun with the Amiga etc.

Thanks! You really should thank the guy at this big company who sent me these first displays for about free. He happens to be a Propeller hobbyist and in charge of these displays!

And, I actually think I'm breaking even on this venture (or maybe even making a bit of money) as opposed to my other ventures that probably lose money...

Ray, will you be selling anymore touch screens in the future? I had to reallocate my money for a laptop power supply and battery that went bad so I couldn't get any in the last 2 opportunities. sad

I did do something for a friend and got one screen and mctrivia's breakout board in exchange. If I get the PIC Chameleon that's on my Christmas list I'll be using the PIC half to try to build a 24 bit color driver for the Propeller half.

Will work for Propeller parts!

Yes, I'm sitting on a box of 100 right now... I need a little break to put some PSMs together and get a 6-bit driver going... But, I'll likely start selling them soon. But, the new price will probably have to be $17 to $19 due to increased costs...

Mctrivia just got my last 40 from the previous batch... Maybe he'll undercut my new price...

I would not do that. As I said when asking for them I am building an ai platform and needed a cheap touch screen.

24 bit LCD Breakout Board now in. $21.99 has backlight driver and touch sensitive decoder.

I wouldn't care, just mentioning it... I didn't know you were keeping them for yourself, I was assuming you'd be selling them...
Either way is fine with me.
