Seems to be working well with QNEthernet ! I'll leave it running for the weekend but so far no weird behaviours. Thanks for your help !

Oh thanks that’s very nice of you ! Will give it a try and report back !

Possibly ! Is it API compatible with the Ethernet library ?

After a bit of research this might be related to MDNS: https://github.com/vjmuzik/NativeEthernet/issues/23

Hello, I converted a sketch I had that was using Serial to NativeEthernet. I noticed that after a few hours, the Teensy seems to either reboot or hang. I was wondering if someone could have a look at my sketch and see if I made any errors that could lead to this ? The program uses OSC to set...

Thanks Paul !

Hi! I did not have time to try it myself but my co-worker did and it works great!

Thanks for the very detailed response Paul ! I'll report my findings for sure. The idea of using the Zero4U was indeed to power it via it's JST connector, easier to integrate in a casing (and cheaper!) than taking apart an existing hub. I like the idea of having a few ports built-in + the...

Thanks for your answer, just ordered the Zero4U so will test soon. The Zero4U is just a normal hub with a Pi footprint so if 2 regular hubs can be Daisy chained I assume it'll work...

Polite bump !

I'm planning on building a USB midi merger/router with the Teensy 3.6 and was planning on using this hub : https://www.adafruit.com/product/3298 as I could easily embed it in an enclosure with the Teensy. I was wondering if I could then plug an external hub to the first one if I wanted to add...

I just updated the code to include the Timer library. Compiles fine here for Teensy LC with USB midi.

The first byte of sysex is the manufacturer ID, I choose 127 here. The sysex in my case is sent by Max/MSP or Lemur template.

Thanks for the troubleshooting, I'll update the code soon!

What errors are you getting?

I implemented ArtSync but have no hardware to test right now so it would be great if you could test this out. The sketch is here: https://github.com/natcl/Artnet/tree/master/examples/OctoWS2811/ArtnetOctoWS2811Sync (I also added a NeoPixelSync example) Make sure you use the newer library (not...

I’ll see if I have time to implement art-sync packets. Reading the post it does seem some tweaks are necessary in the Ethernet library though...

The Artnet Library works with more than 3 universes, this is a specific issue with MadMapper, is this the software you are using to send ?

Not sure if this can help but a couple years back I remember that forcing the Ethernet adapter speed to 10mbos on my computer helped with performance issues on the wiz820io. Might be worth trying...

Increasing the artnet buffer size will not help and might cause problems. Are you saying you tested this before with ws2811 and it worked well ?

Thanks Paul !

Hello, I've been using the Ethernet library with Teensy 3.2 + Wiz820IO + the adaptator board for months without issue. I recently updated my software to Arduino 1.8.2 and Teensyduino 1.36 and it doesn't seem to work anymore. I tried several sketches all with the same issue. To reproduce, you...

Thanks will go that route!

I just bought a couple of USB MIDI Host boards (http://www.hobbytronics.co.uk/usb-host/usb-host-board-v2) With the goal of using the Teensy as the merger/router. My goal would be to power the Teensy and all the USB host boards from a single USB cable plugged into a USB wall charger (the ~2.5A...

I don't think so, I'm using a mac too. Can you try with another software ? Vezér has a free demo and is pretty easy to get running: http://imimot.com/vezer/ Also perhaps try the latest version of the code: https://github.com/natcl/Artnet/archive/master.zip as there was a small fix on how the...

Not sure if this is related but Arduino's Ethernet library will set the gateway to 2.0.0.1 by default, perhaps try changing the ip of you computer to 2.0.0.2.

try changing the subnet mask of the sender (i.e. 255.255.255.0)

I've been using the library on several projects without issues, the most common errors are bad network settings. What software are you using to send and what are you network settings ?

I ended up using code from this post: https://forum.pjrc.com/threads/28545-DMXSimple-Issues?p=111536&viewfull=1#post111536 Which seems to solve the speed issue I was having with the original xmit() version, the full code with midi is here...

Update: I got it working by using Serial2 (pin 10) but pin 1 wouldn't do anything, strange... I don't seem to have ram problems but if I try to send all 512 channels the framerate seems to drop quite a lot... I also tested it on a Teensy 3.2 with the same results. Would there be a way to...

Hi Paul, I tried the example code (the colorwipe with the xmit() function) On the TeensyLC it doesn't seem to work at all and it works fine on a Teensy 3.2, any ideas what could be wrong, Serial1 is pin 1 on the LC right ?

This could be great for the mqtt/pubsub library !

@Paul, do you think the Dmx Serial code + using USB MIDI library will work on the TeensyLC ?

You need a pullup resistor but it's already built into the Teensy. You would connect the ground pin of the sensor to ground and the other pin to your digital pin. To enable the pullup it would look like this: pinMode(n, INPUT_PULLUP);

Indeed, I swapped the radios and if I put the 2 radios next to each other I get an RSSI of -55 on the server, if I re-swap I get an rssi of 0 on the server... Does this mean the radio is broken or is there something else I could check ?

Thanks, Anything under 50ms should be fine. I just figured I will need it to be bi-directional too so perhaps it's not that overkill. I'll need to be able to send a message from the computer to the device too. I monitored the server sketch instead of the client and the server seems to receive...

I've been playing with the settings for the Radiohead library but I'm not sure what would be the best. My application is that I want someone to press a button on one of the unit and receive the signal on a computer with the less latency possible. Any suggestions on which settings should be best...

Thanks steve, The schematic seems to be here: https://cdn.sparkfun.com/datasheets/Wireless/General/RFM69HCW_BOB.pdf The spark fun page says it can draw up to 130ma and the teensy seems to be rated to 100ma max so that could be the issue. I used a simple wire antenna cut to 78mm as per the docs...

Hello, I'm trying to make 2 Teensy LC communicate using the RFM69 chip (using the Sparkfun breakout board): https://www.sparkfun.com/products/12775 I was able to have the 2 libraries communicate but as soon as I'm 6-12 inches away I seem to start loosing a lot of packets. I'm using the...

Many thanks !!

I can reply to #2: Yes that would be possible with the Art-Net library and quite easy to do.

Hello, Just wanted to mention that the project went very well. To make sure I wouldn't have too much voltage drop I used an RS232 convertor: https://www.sparkfun.com/products/11189 I had one master teensy connected to 5 EL Sequencer boards. The communication was done using MIDI so I assigned a...

What hardware are you using ?

This is indeed how the spec is designed, however many software don't respect that topology and send more universes. There is nothing in the Art-Net library for Teensy that prevents it from receiving more than 4 universes, however, it is possible that the client only sends a maximum of 4 universes.

Can you post your code ? Did you try the simple receive examples ?

Nice ! Seems like a very useful shield ! Eager to test it out and thanks for putting me in the list !

I've been checking the VBAN protocol lately (http://vb-audio.pagesperso-orange.fr/Voicemeeter/vban.htm) It's an open protocol for streaming uncompressed audio on the network via udp. How realistic would it be to use a Teensy 3.2 + Audio Adaptor + Wiz820io to decode the stream ? I assume I would...

Paul, I checked the quad output example and was wondering, does the 10ms delay to parse the header cause the files to be slightly out of sync ? If so, would there be a way to get them to sync ?

Thanks I'll try that first !

Thanks for the answers. Just to clarify I don't need to receive data from the EL Sequencer boards, just send it from the Teensy. I don't mind sending the exact same data to each board as I'll be sending MIDI and will use different MIDI channels for each board. So HardwareSerial + SoftwareSerial...
