Hi Holly, I am now trying to get the sony acx705akm LCD interfaced to the gumstix. got it for 20 bucks on electronic goldmine. i had read one of your earlier posts about trying to get the same LCD to work with the gumstix. Can you kindly give me some pointers as to how far you have been able to get it to work?? If you are halfway through the interfacing work then i will be more than glad to finish it and post the steps on the wiki. thanks, Bhaskar. |

OK gumstix-peeps, I finally spent some time getting the sony 6.92cm color TFT set up on a gumstix. I was going to wait and put a connector for it on a board I was planning on revving sometime soon, but I couldn't take it anymore and just jumpered a connector onto an old board and got it working (mostly). I've spent a _lot_ of time working on displays, particularly on SA and pxa, so I wanted to spend some time on this and get something done so people are not stuck out there reading datasheets and decoding LCCR values for days at a time. I think I have some color bit inversion or something going on since the colors have some nasty banding on grayscale images, but the solid color images look fine. Could just be the fact that it is only 3 bits per color though and I didn't dither the source image. Anyway, maybe I'll look at that tomorrow. I can hopefully post the hardware design to the wiki if I end up doing a board which supports this display. You can probably glom this onto one of the standard gumstix expansion boards too, though soldering to the 0.5mm 22 pin connector is a little challenging without a good microscope and iron. Hope this is helpful for people out there, enjoy, and please feel free to give me feedback or change the wiki page yourself if you make improvements: http://www.gumstix.org/tikiwiki/tiki-index.php?page=Display -Holly Bhaskar Mukherjee wrote: >Hi Holly, > I am now trying to get the sony acx705akm LCD interfaced to >the gumstix. got it for 20 bucks on electronic goldmine. i had read >one of your earlier posts about trying to get the same LCD to work >with the gumstix. > Can you kindly give me some pointers as to how far you have >been able to get it to work??

One interesting application/library for this would be svgalib (http://www.svgalib.org) along with something like zgv (http://www.svgalib.org/rus/zgv/). I've messed around with this on an old laptop and it makes a great non-X slideshow viewer. If anyone gets this working on gumstix I will definitely be interested :-) Jason Holly Gates wrote: > OK gumstix-peeps, I finally spent some time getting the sony 6.92cm > color TFT set up on a gumstix.

This morning I looked into the funny image banding and discovered I had the LSB and MSB swapped for each color. After re-wiring those 6 bits on the connector and making some other timing adjustments, the display works great. I've updated the wiki page and the attached files for interested parties. -Holly Jason R.
