Video of buffersize 9 and also with
xTaskCreatePinnedToCore(FastLEDshowTask2, “FastLEDshowTask2”, 3000, NULL,3, &FastLEDshowTaskHandle2, FASTLED_SHOW_CORE);
the other adjustments buffer 10 …settings make no difference so i can see
missing/deleted image from Google+
@Stef_Weicks in that case the size of the pinnedcore doesn’t have any imapct.
Can you tell me the size of the file. And the number of frames you’ve recorded?
at the beginning and sec 59 in the video you can see the white lightning
7,32 Mb 1000 frames
@Stef_Weicks oki the size is right. Can you try saving 5000 frames and let me know the size ? Of the file ?
@Stef_Weicks In thé command xtackcreatePin…
you have NULL,3 change that in NULL,1
@Stef_Weicks in the file artnet.cpp
Find the line
readbuffer=(int)buffernumber/2;
And replace by
readbuffer=buffernumber-1;
This should give more ‘space’
sry at the moment i had some other work todo … now i´ll check the filesize by doing 5000 frames
filesize is 37.500 kb
also with jerks in the animation… i will check your changes in the artnetcode
@Stef_Weicks correct size.
I have setup an sdcard and see that to write one frame on the sdcard it takes 21ms which is more than the time between two frames hence despite the buffer at every 80-100frames ie 3-4s the buffer will be overloaded hence the jerk and the feeling of coming back.
Conclusion:
It’s not a WiFi issue even going with serial the issue will be the same.
Solution:
1)reduce the FPS of jinx
2)export the universes as file from jinx and then merge them with a small program. Or change the read program to read all universes file at once …
yes i tried it at the moment … there are already jerks in it… so whats the best solution to do… now i will try to reduce the fps in jinx
@Stef_Weicks I maybe have the solution instead of writing the entire frame at once I could write universe per universe
in jinx i found a possibility to reduce the framerate to 20fps but its not as easy i thought…
ok … and you think that would spare time for saving?
@Stef_Weicks
could you try this program
and give me the serial output
SD Card Type: SDSC
SD Card Size: 971MB
@Stef_Weicks wait couple of minutes more should be displayed 
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
Your card is even slower than mine I will do some test with my card and my panel when I have good results I willl let you know
oh shit ! … otherwise i have to buy a faster card
