About animation bug

Post by matajumotors »

Hello, Ladyada.
I have received a 4K EEPROM today and uploaded 4 images to it. It all works, exept, that first line, or maby last line of the slide is in the next slide! It is like picture is from adress 1 to 1024 but not 0 to 1023 or etc. When i uploaded images to EEPROM, it always says "Died at adress 1024"
BUT if I read the images from EEPROM, EVERYTHING is pervect, no errors and slides ar just like I uploaded.

Any thoughts? How tu fix that? It is just 1 thin line, but i don't like it ...
Here is a Video http://www.youtube.com/watch?v=QGQPXD5DEf0

Pls someone who tried animations, have you that kind of bugs?

OK.
I tested more cearfully.

First line (of 256) of a slide, goes to the previous slide end ... :roll:

I puted in each slide a number - 0 , 1 , 2 , 3 and in slide 1 i drawed line at first adress.

Then i started spinning and wached animation - numer 2 ... number 3..., number 0 WITH LINE! and number 1 WITHOuT ...

rrrrr

Hi all

is there anybody solved this problem?
the larger eeproms (over 25lc0180) have a vertical line in picture at the back side (with original atmel firmware!) .25lc160 has the same poblem (2pic)
the single 8kbit memory (1pic) has no vertical line in picture!

i use 25lc640 (8pic) and there is a line on back side,and looks like some shaking on the picture (just a little 1pixel)

any suggestion??

animation problem

Hello, Ladyada.

can you help me a bit? to solve this problem.
i am sure its simple for you

when i set mirror flag in spokepov the picture has a 1 pixel widht,and 4 or more pixel long vertical line at top of the picture on front side (i checked,opposite side like the download debug led test)looks like this is the front side because the picture is in the right direction ,like in screen.the other side is good no line.
this vertical line is not the part of picture,and there is in all.
when i use the mirror flag there is a line in the picture.looks like when the firmware starts to write the picture or end it.this is the first or last ? vertical line.when i use 1k eeprom 25lc080 ther is no any problem with mirroring.i use bigger,i tried with 25lc160,320,640, there is a line on first side picture. if i dont use mirroring with larger eeprom ,the pictures are good,but no mirroring...

i made few pictures to see the bug.not so good quality but you can see the problem.
