    Matt,

    I would stick to a simple breakout board for now...and expand on that if Rayman gets more screens. You will reduce costs, and prevent risks of having a EOL item.

    I would also go with option 2, but later make a board that had the prop, crystal, SD card, etc. and put a 2x20 header on it so it could plug into option 2.

    Just the breakout is really important to have ... think about all those sparkfun boards.

    I'm sure Rayman will produce a nice board with the Propeller and other stuff.
    Actually, If I was in Rayman's position, I would be asking for a little payback in return for creating the market.

    I am reviewing the datasheet attached to the very first post and having a bit of trouble determining the proper opening size for a case. Page 27 in the PDF is the Outline Dimension DWG and there are several dimensions with abbreviations on the perimeter of the front side view (the view on the left). Here's what I have figured out for the abbreviations/dimensions by using the design guide notes on page 14/15 of the PDF (section 4.3) and the Outline Dimension DWG on page 27:

    OUT SIZE = Outer dimensions of display
    TSP = Touch Screen Panel
    TSP V/A = Touch Screen Panel Viewing Area
    C/F POL = Crystal Film Polarizer?
    TSP A/A = Touch Screen Panel Active Area

    It appears that the viewing area (inner bezel dimensions) as defined on page 15 should would make the width of the hole in the case 98.7mm (104.9 TSP - 3.1mm (left bezel edge) - 3.1mm (right bezel edge)). The height of the hole would be 56.5mm (64.9 TSP - 3.1mm (top bezel edge) - 5.3mm (bottom edge))

    Anyone else take a hard look at the dimensions for making a case opening?

    @mctrivia, My vote is for option 2. Minimum components, connector, header(s), ?.

    Not sure how much can be included and still be called "breakout board".
    I'm know Rays PSB will be at least as impressive as his PSM, and that is saying something.
    Sounds like he could put the extra time to good use.

    Keep at it Ray.

    Just want to point out a very nice thing about this display for you driver writers out there...

    Although I've just more or less used the standard VGA tile driver scheme, this display allows much more flexibility with the Prop because you're not tied to 60 Hz... In fact, the display looks great even at 14 Hz. I don't even think the refresh rate has to be constant.

    So, cool things like 80 column text with a custom size font (like 6x10) should be possible. Also, 6-bit pictures should be possible in one cog. I'll have to see if the i2c or SD card busses are fast enough to escape main HUB ram size limitations...

    Also, I bet one could do a proportional font... I'm still dreaming of an LCARS interface:

    I noticed I forgot to run the I2C touch information to header so here is an updated schematic and part layout.

    I have not gotten a quote back on how much assembly will cost yet but it looks like fully assembled and populated the boards will cost about $19.99

    If you do not need the backlight or i2c touch screen then we are looking at about $9.99

    Ray,

    Just wanted to say thanks publically.

    IMO, with your first direct selling adventure, you've done the prompt and courteous customer service we always hope for.

    You'll do well in your future ventures!

    Looking forward to buying things from you in the future.

    - Howard

    Actually, going without the touchscreen may make sense in certian cases...
    I've heard that you can put the whole thing on a hot-plate and remove the touchscreen (or something to that effect).

    I think the display would be prettier without the touchscreen... The touchscreen always adds a bit of haze...

    PS:· Thanks Howard!·

    keeping back light but removing just touch screen would make $15.99. Of course I am assuming James will give me a decent deal on the assembly since I have made it really easy for him.

    it is kind of crazy that the ics each are almost the same price as the screen [noparse]:([/noparse] more expensive since i assume you are making a profit selling them.

    By default the I2C A0 and A1 will be set to 1 but it can be easily changed by removing the 0 ohm resister and adding a new one in the 0 position. There are pads on the bottom of the pcb for 2 extra bipass caps. They will not be needed for most applications but i made them available for easy additions if you want to be extra careful.

    To keep prices low I can only make 2 of the following options and need approximate numbers of each to have assembled.

    1) Bare PCB $4.99
    2) Header only $9.99*
    3) Backlight and Header $15.99*
    4) Everything $19.99*
    *prices estimates only depend on assembly quote.

    Those prices are probably better than what I could offer...
    I still think more people would want a 6-bit color interface than a 24-bit interface, but I could be wrong...

    I suppose somebody could just use jumper wires·to make yours whatever they wanted though...

    One non-obvious design point... I've added a pull-down resistor on DON because the display goes haywire sometimes if this is left floating... Adding this resistor lets people share pins with the VGA driver without having to handle code to control DON to switch back and forth...

    My PSB prototype shares sync and color pins with the VGA port. The idea is to pick one or the other. And, to use existing VGA code without modification. Problem was that the LCD would go haywire and pull down Vdd unless DON was set to 0 first...

    Matt,

    How are you panelizing those...and if you used our calculator......we will probably give a break.......mainly because this is a project on the Parallax forum.

    I think we can do it for the price mentioned, but you would need to email me what you think the assembly price is calculated at, for us to make sure.

    But, even at $50, I think these things would be a great deal. You guys are lucky I'm not greedy!
