I’ve got some pictures online…

These are 3002x2000 images, around 3MB each. Probably only the first and third images are interesting. The first shows the full setup, where the second is zoomed in on the screen. The second came out darker though, and the screen content is more clear in the first image. The third image is the same Qtopia application (gradients) running on the Gumstix but displaying to a VNC server, as viewed on a Windows machine.

 

Since the application is designed for a much larger screen area, I don’t expect it to look great on the 240x160 display, but I don’t think that’s the cause of the bleed that’s visible in these images. Probably a frequency configuration issue?

I snapped one prior to my last email, but the picture came out terribly (on a mobile phone camera, under poor lighting). If I can get a shot that shows things better I’ll post a link.

Hi Mark,

 

Any chance you could get a couple of pictures of the screen at work?

 

Thanks,

I got the display to light up with recognizable data… it's far from good looking (or even usable), but it's recognizable.

 

The test program is a Qtopia demo application, "gradients". I've run this program against a VNC buffer to make sure it runs and it looks perfect in VNC – except the application is much larger than 240x160, so it might not be a good test case. The physical display shows the upper left of what I expect to see, and the colors are more or less what I expect… the problem is the screen has a large amount of horizontal jump, like a clock isn't at the right frequency… this leads to a fair amount of pixel bleed towards the right.

 

I set the registers according to the script at http://docwiki.gumstix.org/Display#Setting_up_the_Sony_ACX705AKM_on_gumstix.

Hi Mark,

How's this going?


I'm doing the same work with the same components too. Yesterday night i've wired the frontlight and it works (from 6V, 15mA). Hopefully today i'll do the rest and show some pictures on it.
Good luck!
