ok … iam doing
@Stef_Weicks
the use of the matrix (from Neopiwxel is to profit from all the function to manage the tiles and the print
but the library actually doing the display is FASTLED (to profit from the paralell output)
thanx … i thought so
first video, here you are

@Stef_Weicks Cool !!!
I like that too! i think you know, on a video you can´t see how cool it is in reality 
Thank you for the implementation!
now i found out something strange… i have a noname microsdcard and i tried a few animations… but i think this card (normally a fast HC card…i thought) is more slowly than my 1GB Card. in the animations are a lot of jerks although there were no lost frames while recording…
so i took my old card and everything was fine .
missing/deleted image from Google+
a nice effect: i would say the disappeared time

hopefully my 2 new panels will come soon … I do not like that on the right side
@Stef_Weicks normally the program should give you the average writing time. Is it slower and this other card ?
No frame lost doesn’t mean it did write correctly. Do you have the ‘depassement’ stat on the writing program ?
@Stef_Weicks are you not sure your panel are correctly wired ?
The animation seems off
Either that or your universes on jinx are mixed up.
Try a simple scroll ?
but i like this new decent look of the clock … i got the RTC on and off and the only thing what i changed was this line:
matrix->setTextColor(colors[40]);
my “old” 1GB card:
SD Card Type: SDSC
SD Card Size: 971MB
time for one frame 26.809999 ms
time for one universe 3.878000 ms
Total space: 970MB
Used space: 36MB
and my “new” 4GB Card: (with this card its jerking)
SD Card Type: SDHC
SD Card Size: 3781MB
time for one frame 135.188995 ms
time for one universe 3.073000 ms
Total space: 3773MB
Used space: 0MB
@Stef_Weicks indeed 135ms mer frame that is slow way two slow. Did you reformat the card ? Maybe it will help
i thought that sdhc cards can read faster than sd sc cards … so i was confused about this result.
now i formated the card :
SD Card Type: SDHC
SD Card Size: 3781MB
time for one frame 34.297001 ms
time for one universe 2.998000 ms
Total space: 3769MB
Used space: 0MB
much better but also slower than the sdsc card i have…
i think this card don´t work…
recording says:
frames saved:2000 frames lues:4108 lost frames:2
time per frame 77.661499
but the animation is jerking and sometimes it runs fast and than slow … hm … donnt know what the problem could be
e@Stef_Weicks you are missing on stat
But yes indeed you saved 2000 frames out of the 4108 totally read so you save less then half of it. That is not good
The lost frames=2 is the number of frames lose thafzdue to WiFi.
I should changed my definition of lost frames to take that into account too
You are missing on stat such I think would have been really high.
Time per frame 77 !!! Whoua you would a need a frame buffer of 100 at least not have issue.
This card is really bad
Rpr
@Stef_Weicks when you look at the stats the ‘new card’ is faster at writing small files (3ms vs 3.8ms which is like almost 25% faster, but then when writing large files … it’s a mess. That is why I thought of formatting to ‘re arrange free memory’ into contineous block. But it was not enough.
You should remove the ‘partition’ create a new one and reformat and ‘slow format’
@Yves_BAZIN yes the postet result was with a slow formation of the card, but now i deleted the formation and did a new formation (also slow)
frames saved:2000 frames lues:5404 lost frames:1
time per frame 108.746498
donnt know … why this happens…

till now i tried to get blynk to work with the panel … do you know blynk? because than i could switch on and off the panel or change the animated files with my phone.
the problem here is, i have to put a command in the loop() -> Blynk.run();
and if i am not connected the panel works fine except for a few faulty flashes of the animation and if the controller is connected with my phone the faulty flashes are much more …
i think the problem is because of the blynk program which needs to much time in the loop()… maybe you know how to modify that this could work?
i would try it also with cayenne now… because there it is possible to modify the routine time.
@Stef_Weicks can you make a video of what you see ?
ok i tried it with cayenne now … its also like with blynk …
