A lot of delay and multiple issues on ArtNet transmission

[bygerardvisuals]

Hello,

First of all, huge thanks for this amazing library. I've been using it for some years with no issues, and it works amazing.

Now I'm trying to use it to control a pixel matrix 60 pixels in width and 20 pixels in height and I'm having huge issues with the transmission. In total, there are 1200 ws2812B pixels and I'm using the ArtNet FastLED example as I always used. I'm changing the number of LEDs to 1200, my wifi credentials and the data pin. Do you have any recommendations to solve this issue? I thought about splitting the signal into multiple pins but not sure about how to do so efficiently and if it will do or not something is into the issue I'm having. The controller I'm using is the ESP32 C3 supermini, and MadMapper as the mapping software.

Thanks a lot in advance and I hope this also helps other people in the future.

All the best,
Gerard

Hi,

thanks.

This is a massive number of pixels. All my testing was done with maybe 100 LEDs.
Here are some advises I can give you:

• Try to split the matrix at the universe level (every 170 LEDs).
• There is a example ESP32S3 for the ESP32 S3
• Only update the matrix at the end (e.g. when receiving the last universe/LED)
• Try reduce the frame rate
• Maybe the ESP32 is not that powerful to handle such high number of LEDs. Maybe the S3 is a better option (see above)

Hope this helps.

Hi,

Thanks a lot! I will try that and let you know

All the best,
