ArtNet to Neopixel freezing

[lyon470]

Hello i have the Artnet Neopixel example running and changed it so that i can set the subnet mask.

Now I have the problem that my output to the neopixels freezes every 4 seconds and nothing changes anymore.

Anybody know what I did wrong?

[natcl]

Can you provide more info? Your full sketch, on what microcontroller? What software is sending artnet ?

I'am using Arduino Mega with Ethernet Shield and Resolume to sending ArtNet.

This is the Sketch i'am using:

include

include

include

include

Artnet artnet;

// Change ip and mac address for your setup byte ip[] = {10, 0, 1, 199}; byte broadcast[] = {10, 0, 1, 255}; byte mac[] = {0x04, 0xE9, 0xE5, 0x00, 0x69, 0xEC}; byte sub[] = {255,255,255,0};

void setup() { Serial.begin(115200); Ethernet.begin(mac, ip); Ethernet.setSubnetMask(sub); artnet.begin(); 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++) { Serial.print(artnet.getDmxFrame()[i]); Serial.print(" "); } Serial.println(); Serial.println(); } }

And what happens without the subnet mask modification?

Without the the modification it works correct but i need to configure the subnet

[natcl]

Is it possible the subnet on the sender is not set correctly?

the subnet and the ip on the sender is correct. The freezing ist only when the subnet is at 255.0.0.0.

[lyon470]

Is there another way to change the subnet ?

[natcl]

Seems like it's part of the Ethernet.begin() constructor: https://www.arduino.cc/en/Reference/EthernetBegin

No i dont't think so because it works correctly when the subnet is at 255.255.255.0. Only when the subnet is at 255.0.0.0 it is freezing.

Now i figured out that the freezing is every time an Art Pool ist coming in.

[natcl]

The test sketch you posted above, what is the output in the console? Do you get poll messages and data. What do you mean by freeze ? It stops forever or it's a hiccup in the frame rate?

The Ouptut in the console is correct (i get data + poll) but every time a poll is receiving the data stops for about 1 or 2 seconds. It don't stop forever it's like a break in the data signal every time a poll is receiving.

[natcl]

I wonder if the broadcast address for your network is good, perhaps try changing it in the sketch to 10.255.255.255 ?

Thanks so much. Now it's working perfect.

it is possible to change the artnet.begin(mac, ip) to artnet.begin(mac, ip, dns, gateway, subnet); and how can i change the ArtNode name that is sending in the poll reply

[natcl]

Yes you can use the Ethernet.begin call as you would in a normal arduino sketch. You can’t currently change the name via the sketch but you can modify it in the library, here are the lines: https://github.com/natcl/Artnet/blob/master/Artnet.cpp#L107

Thank you for the good support :+1:

Now everything is working.
