@Stef_Weicks
new record
and new arnet (just added some stat info
i have put the variable for the number of universes and number of frames at the beginning of the program as variables.
@Stef_Weicks keep the same card
and try my new recoding method
and send me the output
192.168.1.30
buffer0 created
buffer1 created
buffer2 created
buffer3 created

over 2000 frames I lost 30 my guess it’s really wi-fi related this time

Looks great on your wall! seems that it works for you … i got an
Guru Meditation Error: Core 1 panic’ed (StoreProhibited)
let me see… hmm
@Stef_Weicks what size of buffer do you have ?
If 15 that will be too much try 12 or 10
Me I have to stop at 5 ‘cause I have more pixel on my panel but I think 15 frames buffer is too big too
12 … i´ll try with 10 now
ok …now its recording… we will see
YESSS !!.. seems to work good now!! e few small jerks… but only if you pay extra attention to it you can see it
@Stef_Weicks btw when I look at the speed of your SD
It needs 18ms to write on frame for you ie 2560 pixels
And me 20ms to write 5904 pixels
I can write more than double the speed on my sd card. I suggest you try several sd cards if you have some around and choose the one with the faster writing.
@Stef_Weicks i have re run the same program

only one frame lost 
this time
ok … i think i will buy a new one! the speed is adjustale if(!SD.begin(5,SPI,80000000) // by reducing the frequency
or do you mean only a sd.card with faster writing speed with no adjustments in the code??
the smaller buffersize is because of the ESP i have?
frames saved:1000 frames lues:1010 lost frames:0
time per frame 17.584999
@Stef_Weicks the frequency 80.MHz is the maximum speed the spi try to write. The slower the frequency the slower the writing. But at the same time you sd card has speed limitations due to its composition. Hence even if the spi tries to go as fast as possible it will only go as fast as the sd card.
So we should keep 80Mhz to tell the esp go as fast as you can. 80Mhz being the maximum speed of the spi on esp32
@Stef_Weicks 0 frame lost
Play it now !!
Thank you that´s understandable! and the buffersize? why is this smaller on my setup?
i played it … there are also some small jerks at the beginning the rest is very smoothly!
@Stef_Weicks
So way better now ?
the larger the buffer size the better !! I am gonna change the memory allocation to try to be able to get more buffer.
I think with a faster card you will have 0 issue
Here is mine

ok thanks … i will buy one… you don´t know how to reactivate a “non formatable” sd-card? i tried it with the windows tools… the 32gb card is displayed (also with its size) but not possible to format.
@Stef_Weicks your buffersize is bigger. You have 10 I have 5 
Try 11 to see if you can make it
no … 11 is to much Core 0 panic’ed
@Stef_Weicks I have a Mac sorry ;(.
Have you looked on google ? Sometimes you can find good tips
Have you tried the disk tools form windows first create a partition and then format it
