Here is a photo of the pcb. It uses a variant of the processor IC in Steve's picture frame.
Update: Would have to use thin pcbs if we were to replace the pcb. The Xtal is a problem as it has to be located in an area where we can place a hole in the pcb. I don't know what freq the second watch can is. One will be 32KHz for the digital clock. Actually there is more circuitry than I expected. Pity the AX203 is an OTP. Erasable would have been fun to interface it to the prop and we would have USB2.0. We lose that when we replace the cpu with a prop.
Just wondering how I could simply get a bit more depth? I don't want to buy 2 iust to get another case although it would work gluing two cases back to back. Would be nice though - could stick a RamBlade in it also :-)
Of course it would be better just to program my Windoze phone, but no fun !!!

@Rayman, A 2.8" OLED under $30 ? Can't beat that with a stick [noparse]:)[/noparse] Can't wait to see the details.
@Cluso99, That's a sturdy looking case with some room for extras maybe.
The LCD looks like it will use 19 Propeller pins: D0:15, RD, WR/, RS. Don't you just love having 65K colors for a Propeller ?
Both the DP151 and Nokia Knockoff LCD have that; the format is 565 RGB (or BGR for DP151 LCD).
I was looking at the DP151 stack-up again, and it looks like 0.92" PCB to LCD clearance.
The current FAB is 0.42" ... hope I can find a cheap vendor to do that size.
Steve: From the extra info you have found, looks like we could just substitute the Windbond SPI interface with the prop to provide the picture out to the AX203 (AX206 in yours). Maybe cut the SPI tracks to the Winbond chip and re-route via the prop. Your thoughts???
▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔▔ Links to other interesting threads:
You could try that as a "video interface" for Propeller I guess, but the update rate is way too slow (for the device I'm using at least ) for that to be practical. If you don't care about the update rate, that wouldn't matter much. The simplicity of the hardware connection is attractive of course.
If the DP151's AX206 is really downloading/running code from the SPI Flash, I could see maybe using this as a hack for modifying the AX206 run-time -- the AX2** devices are based on 8051 code, so conceivably you could write apps for that. Lots of hacking would be necessary to understand the details.
I probably won't pursue either of these possibilities. I have other nuts to crack that seem a little more tasty right now [noparse]:)[/noparse]
That was a Squirrel metaphor [noparse]:)[/noparse] Don't read anything into it that is not there [noparse]:)[/noparse] Some say I'm a little nutty (I'm not fruity though).
I'm trying to figure out another way to make better use of existing Propeller memory and external serial devices that would be reasonably fast and be compatible with current Propeller programming methods ... read this: en.wikipedia.org/wiki/Paging.
Of course I have these boards to design to make hacking the DP151 easier. Soldering wire-wrap to tiny little SMT propeller pins is exhausting and impossible for some people who participate here. Writing the instructions for showing others how to solder those little pins and where it all connects is equally difficult.
I said mylar :-( I don't know the difference and cannot see the actual mylar/kapton properly anyway (yet).
The AX... series are 8051 OTP based extensions. I noticed they seem to switch some instruction sets on the fly. Inc -> Dec, etc. They have been specifically targetted for photo frames and have a security bit.
Steve, thinking about substituting the flash with the prop. Since the AX... does not have much internal ram memory, it would have to fetch the display buffer row by row, so would be fast -OR- is the screen buffer held in the controller chip on the LCD (and therefore it is the 8051 that is replacing this slow) ???
Shame we cannot get to the USB 2.0 interface on the AX... I am presuming these chips are not readily available except in masses to photo frame builders ???
The 65K colors is great, but for that we will require external memory on the prop as 240x320 = 76.8K pixels x 16 bits = 153.6KBytes. So if we only use hub ram then we have to reduce resolution or colors - ouch!
However, I am extremely happy with my buy - may get a couple of extras as they are on special which may mean they are discontinuing them. The display and case is too good to miss at this price
Postedit: Steve, does the DP151 have 2 xtals?? If so, it the second one 24MHz??? I don't have anyway to measure mine and from the spec it has to be 24MHz to double internally to 48MHz for USB2.0. The watch can is a nice size - I must try mine out on a prop. 24 & PLLx4 -> 96MHz (will try 24 & PLLx8 -> 192MHz for overclocking just in case it works)

I guess that all depends on how you make your images [noparse]:)[/noparse]
The LCD has all the memory we need for display. The animations I made do not use Graphics.spin and some big buffer. I'm not sure how Rayman is doing it, but he has Graphics.spin running with his PSM and it's pretty awesome [noparse]:)[/noparse]
The Propeller Beanie in my last demo video was taken from the Parallax web site and run through a variant of Andre's bmp2spin converter. I was thinking about how many colors to use this morning. The beanie was only 4; 16 colors per sprite should not be very hard to do.
The update rate I'm seeing for the pictures may be a function of how fast the data can be fetched from the SPI flash by the 8051 (which appears to be running at 24MHz). I've had a Propeller running with RCFAST on the Nokia Knockoff which is SPI, and the update rate was comparable. The LCD controller for the DP151 has some built-in picture format modes, but I don't know if they work or not.
The Kapton data sheet shows melting point at 400C or > 700F ... that's wonderful for my heat gun [noparse]:)[/noparse]
As far as prices go, I'm very happy with the margin available for the DP151 at $11. You've probably seen what I mean on Alibaba. Did you see the tear-drop frame? It's cute.
I liked the DP152 as the buttons are on the front, but still only 1.5".
The 2.4" that I bought seems the cheapest in Australia. eBay has the Coby 2.4" but almost $40. Plus I like the better resolution of 240x320. The LCD interface is the same as yours.
Now, need a keyboard - can hack an old iMate JasJam for a small qwerty keyboard. Or maybe design a capacitive pcb and a PSOC chip. I just have to get my RamBlade and TwinBlade pcbs out - but I keep getting new ideas and distractions (and not much time) :-(

Right, the menu button should be in the center.
I do not have a DP151, I have a noname frame from Ebay, the menu button is labeled "M".
The reset button is not a real button on the backside, there is just a small hole labeled "reset". By using a paper-clip, a reset can be performed (inside the frame behind the small hole, there is a button). ·
@Jazzed: Now you know how to tell what is inside the photoframe (AX203/AX206) can you check the 3.5" one you bought?
I would think a pcb which replaced the rear panel on my 2.4" may be the way to go. That way I could put the prop, etc on this pcb and just wire what is required to the existing pcb, removing of course the AX203, etc. The alternative is to just replace the existing pcb and rewire the LCD. Yet another posibility is to remove the battery and use this space, but then you lose the battery function.
I am thinking about the keyboard - maybe an old phone with an alphanumeric keyboard? I am keen on a projection keyboard but they are a bit $$$.

That link comes from this interesting page -- picframe.spritesserver.nl/wiki/index.php/Talk:HK_Unbranded_with_AppoTech_chipset
We are not the first to visit this type of hack. There is some idea that the AX206 used on the the DP151 is programmable ... didn't notice that before.
1MB of SPI Flash on board. LION battery. Now all you need is a uSD card [noparse]:)[/noparse]
