Digital Photo Frame - PF1

posted by sacah on Feb 8, 2010 project, hack,

We were given a digital photo frame a few years back, and haven't used it. So I figured rather than it go to waste I'd crack it open and see what was fun inside.

Markings on the outside:
PF1070803084

Digital Photo Frame
Model: PF1
Keycode: 41787335

Inside I found a LCD screen and 2 PCBs, main PCB has following markings:
DPF-PF1 (SQ812B)
P/N: 5180341
2007-8-14
V0.1

4 main chips on this PCB are:
SQ812B-Q
0730-QW08B4G2
H21028

VXIS
VX1826
Brief

Things of interest:
1. Holes for USB, as I have time I'm tracing back where this goes to try and enable it, see if firmware will detect it.
2. CVBS and AGND markings for Composite video output.

I will hopefully be getting a flash chip programmer soon, then I wanted to have a peak at what's stored in the flash, I'm hoping it's the firmware and I can have a poke around at that, though I haven't had much experience disassembling firmware so see how far I get (-:

I'm also interested in VX1826, it supports I2C(IIC), might be able to use it as an easy I2C LCD screen.

Let me know if you have any further information about any of these chips, or if you have one of these units and have successfully modified them at all, I'd love to hear from you.
