Hello,
I have an Teensy 3.2 and 3.6 how many leds/universe can i drive per Teensy ?

I have the teensy 3.2 and 5 universe Input but the last universe is lacking.
Have i an issue in my code or is this the limit ?

Yes but why i got only 4 universe incoming?
I see in the Serial monitor that universe 1-4 are perfect but i don't get more than that

Yeah many thanks i tested it now with 13 universes without lacking.

But now i have another Problem/issue.
Resolume shows me all artnet nodes in my Network, also the Arduino.
As soon as i tell resolume to send unicast the Arduino isn't anymore in the artnet node list.
When i now change back to broadcast ,the Arduino receives the artnet but isn't in the artnet node list from resolume.

I use the one socket lib from the pjrc Forum.
Hope you can help me.

After a few long days it now work.
I tested 13 Universes but it can be more.

But now i have another problem.
I have two arduino teensy in my network and send artnet over resolume.
In broadcast mode from resolume it work very good but when i change the artnet to unicast the led stripes breaks every 2 seconds for about 1 second.
This is only in unicast and nothing other is changed.
When i now turn off one teensy it work also in unicast mode but not with two teensys.

Why ??
Have anybody an idea ?

I have now changed to the OctoWS2811 library and this worked perfect but suddeny it started to lack and now no matter what i do it doesn't stop to lack.
I use the demo Sketch artnet_octows2811 and only changed ip and the leds.

@lyon470 have you tried the fasted library? It looks very promising since it is more efficient per pixel. This should allow more data to be processed.

Hello,
Teensy 3.2 + octows2811 lib is the best match for teensy based artnet pixel controller (thanks to the DMA buffers, not sure fastled would bring any improvements in a case of artnet only controller).

Few things to do/respect for improved perfs:

#define MAX_SOCK_NUM 1

Now you have increased the perfs of the Ethernet lib. After that there's few more tricks on the octows2811 lib you can do if you don't need a drawing buffer (it should be the case if you exclusively controls the leds from resolume)

OctoWS2811 leds(MAX_NUM_LED_PER_OUTPUT, displayMemory, NULL, ledConfig);

Like this you'd be able to control 8 outs @ 44fps on teensy 3.2

Hi @xseignard , thanks for your tips. do you have any working example for this?.

When you say

8 universes? i need about 13-16. is this possible?

Thanks in advance.

When i now change back to broadcast ,the Arduino receives the artnet but isn't in the artnet node list from resolume.

I use the one socket lib from the pjrc Forum. Hope you can help me.

Is this from one single output?

As I'm aware, the LED itself becomes a bottleneck, as it can only parse so much data, if you want to uphold a given FPS (30Hz or any other number). It receives PWM, bites off the first 3 or 4 bytes (RGB or RGBW), and outputs the remaining part of the signal. But - if you try to feed it 8 universes of PWM signal, it cannot parse it fast enough, and this delay with stack for each LED - adding latency/lagg or similar.

Does anyone experience this problem? Is it not a problem in practice?

8 universes is 27 meters of LED if RGB-pixels are used... That's quite a lot. And you can have multiple outputs simultaneously?

Hi,
I got a Teensy4.1 with the ethernet kit...
tried the receiver example and I'm getting up to 4 universes and a half (i get data up to 2304 channels)
how do I get more universes?

@natcl this one: https://github.com/natcl/Artnet/blob/master/examples/Basic/ArtnetReceive/ArtnetReceive.ino
I made some minor changes:

#include <Artnet.h>
#include <NativeEthernet.h>
#include <NativeEthernetUdp.h>
#include <SPI.h>

Artnet artnet;

// Change ip and mac address for your setup
byte ip[] = {2, 0, 0, 2};
byte broadcast[] = {2, 255, 255, 255};
byte mac[] = {0x04, 0xE9, 0xE5, 0x00, 0x69, 0xEC};

void setup()
{
  Serial.begin(115200);
  Serial.println("Starting...");
  artnet.begin(mac, ip);
  artnet.setBroadcast(broadcast);
}

void loop()
{
  uint16_t r = artnet.read();
  if(r == ART_POLL)
  {
    Serial.println("POLL");
  }
  if (r == ART_DMX)
  {
    // print out our data
    Serial.print("universe number = ");
    Serial.print(artnet.getUniverse());
    Serial.print("\tdata length = ");
    Serial.print(artnet.getLength());
    Serial.print("\tsequence n0. = ");
    Serial.println(artnet.getSequence());
    Serial.print("DMX data: ");
    for (int i = 0 ; i < artnet.getLength() ; i++)
    {
      const int ch = i + artnet.getUniverse() * 512;
      if ( ch < 10 )
        Serial.print(" ");
      if ( ch < 100 )
        Serial.print(" ");
      if ( ch < 1000 )
        Serial.print(" ");
      Serial.print(ch);
      Serial.print(":");
      const int v = artnet.getDmxFrame()[i];
      if ( v < 10 )
        Serial.print(" ");
      if ( v < 100 )
        Serial.print(" ");
      Serial.print(v);
      Serial.print("  ");
    }
    Serial.println();
    Serial.println();
  }
}

I had to change Ethernet.h and EthernetUDP.h to NativeEthernet.h and NativeEthernetUdp.h for this code to work...
I'm just printing the data sent to it... I'm sending 2304 channels, which would take 4 universes and a half... I'm getting all the data, but more than that and data is lost...

I added some spaces depending on the values for better reading...

thing is that when I try sending more data, like a fixture of more than 2304 channels, data is lost...
for example, I set a LRGB fixture of 128px12p, and only getting the top 128x4 but occasionally getting the 11th row or the 4th row is incomplete... it's weird... is it a limitation from the ethernet chip on the Teensy? or maybe is it a limitation on the ethernet cable? is the ethernet kit? is it the Ethernet library? is it my Ethernet adapter on the computer?

@natcl

natcl commented Feb 13, 2024

There's nothing in the library preventing getting more universes, normally if the board is receiving it it should work unless there is a network configuration issue...

@joex92

joex92 commented Feb 13, 2024

Then why can't the teensy get all the data from a big fixture?

@joex92
Copy link

joex92 commented Feb 13, 2024

is there a hardware limitation on the Ethernet module of the Teensy?

@natcl

natcl commented Feb 14, 2024

Do you have a control over fps ? You could try lowering the fps to see if the Teensy is receiving data too fast ?

@joex92
Copy link

joex92 commented Feb 14, 2024

that's another weird thing... when doing the testing, I'm only sending 1 frame at a time... like I just send 1 frame and it still not everything gets there...
another thing I was thinking is that would it be a bandwidth issue? like it's too fast? how can I decrease the bandwidth?
would using an old 100Mb switch in between work?

natcl commented Feb 14, 2024

I know that with the older Teensy 3.2 forcing the Ethernet speed to 10mbps in the OS would help. It might also be a buffer size issue. You'll need to search on the pjrc forums as this is more an Ethernet issue than an Artnet issue, if you go back on this thread there are a couple of links to the pjrc forum with Ethernet optimiza tips.
