Display problems with clip+

(1/5) > >>

Hi, i have recently installed rockbox (r27243-100702) on my new Sansa clip+.
As mentioned above i'm having some troubles with the display, i.e. the screen seems to shifted to the right and the few 'overhanging' pixels are displayed at the very left side. sorry for the somehow stupid description, i hope you know what i mean anyways. Problem is there no matter what theme i choose...

thanks in advance.

funman:
Please take a picture of the screen and upload it somewhere (or attach it to this thread)

My Clip+ works fine btw

rokkon:
For the sake of visibility i just gimped it. Watch the statusbar and time elapsed/time total at the bottom.
This is just an example, the problem remains in all other screens, not just wps.

funman:
Is that a screenshot (top picture) and not a real picture, which you shifted in gimp to give the bottom picture ?

Try to put your camera in macro mode, it makes better pictures (but might require a few tries)

Is the shifting constant ? (it is 2 pixels in your picture but it can't be a real picture)

About the clip+ (well all the clips in fact) screen, the LCD controller has an internal framebuffer of 64 lines which are 132 pixels wide, but the screen itself is only 128 pixels wide.

So if some pixels which should be on the right side are displayed on the left, there should be a 4 columns with empty pixels (we clear these 4 columns at initialization and never write them again).

Can you see these 4 empty columns ?

Also do you have a build environment to try potential patches if we identify a problem ?

P.S. if the problem happens in every screen then changing the theme will have no effect.
Also you might want to see if the 'lamp' plugin works alright (it should light every pixel)

Thanks

The upper picture is in fact a screenshot of the 'literal' theme i took from the themes page. I took this image to produce the lower image which perfectly resembles what i see on the player. I included the original just for comparison. I'm sorry but for now it's not possible for me to take a picture of the actual screen due to the absence of a capable camera.

The shifting is constant and i'd say the last 2 rows of pixels (on the right side) are displayed on the left just like in the fake picture. It's a little hard to count pixels on the player screen though.

I cannnot see any emtpy colums and i'm a little confused where to find them? Again, the fake pic mimics the actual screen quite well.

Lamp plugin looks ok although i can't tell if anything is shifted because all colums are equal in that case.

Applying patches shouldn't be a problem...

Thanks.
