The LED does not show the Artnet or DMX activity. I am using the Arduino version 1.8.3 and the ESP8266 board libraries version 2.3.0. You may want to try the firmware without SERIAL_BREAK defined. So I can locate the problem? Each wifi packet – also when it is not meant for the ESP8266 – will shortly interrupt the microcontroller and thereby cause the soft-serial DMX sequence to be slightly jittered. The UART module which is setup as the DMX receiver, waits for a Break condition to occur on the line. I also tried several different artnet softwares both on my macbook pro and iphone without getting anything anywhere, also no reaction on Supernova (artnet monitor). Ein zweiter Artikel zeigt wie man das ganze praktisch anwendet - UART zu UART, und RS485 als Schnittstelle zwischen zwei Pi's. Will more of those work together? Thanks! Also, my home/neighbourhood wifi is relatively empty; in a more dense urban environment I can imagine that also causing more issues. Is there a way to change the data pin from the NodeMCU to the MAX485 from GPIO2 (D4) to another? If you try to change into AP config mode after the server and DNS starts, there is now a conflict and nothing happens. See https://robertoostenveld.nl/timing-and-jitter-in-dmx512-signals/, Hi Robert,I solve my last problem due a bad electri connector.I’ve a little problem in save procedure. In that case it would also not show in Bonjour Browser. Hi Robert, After a reset frame the payload bytes are transmitted by the DMX host using a start byte (value 0) and maximum of 512 channel value bytes. A reset button would indeed be nice, feel free to implement this and send me a PR with the required code changes. 15:55:33.538 -> If you are not sure whether the communication problem is between Home Assistant and the ESP8266-based DMX controller, or between the DMX controller and the DMX fixture, you could modify the firmware ESP8266 firmware to allow you to check what the values are in the global.data array; the (occasionally) incoming ArtNet packets are stored in there and are regularly (at about 40Hz) sent over the serial interface to the DMX fixtures. I set up everything, connects to the wifi router, gets the green light on the LED, checks Discovery (Bonjour Browser) and router client listing, no sign of the artnet client anywhere, connects to 192.168.1.2 (found this by trial and error knowing that the router is 192.168.1.1), web interface comes up (see result of monitor below). A way around this is to use a different port for the server. Just give it a try. I only have a few DMX fixtures to test with, and so far realized three Artnet adapters. *WM: freeing allocated params!

However, I am not sure whether it would offer the protection that you expect. handleStaticFile It uses the second hardware serial port, aka “Serial1”. For example, you could use the Serial interface to print the data values every second in the main loop. handleStaticFile I am really surprised how smooth its webinterface is (and also much more complex), and I still plan to look into how that it implemented. You may want to update to the latest version of the firmware and install the latest web server data to the SPIFFS filesystem. Last Updated: Jan 13, 2010. Update 6 April 2019 – I wrote a follow up post on the timing and jitter in DMX512 signals and fixed a bug in the firmware. 0 But I realised that the costs of the isolation transformer and optocoupler are more than the ESP8266, so I decided to keep it simple and not  to add over-voltage protection. It finds uses in nightclubs, restaurants and theatres.

Flashed my ESP no problem and instead of making a stand alone unit I removed the XLR sockets inside my LED moving head to make space and fitted the ESP and Max module inside the unit. Incoming wifi requests have to be processed by the MCU, even when not relevant. In case you might wonder, DMX512 is same with RS485 circuit with the DMX512 works only on 1 way communication.

Yes, you can change the code to configure a fixed WiFi network and to specify a fixed IP address. You will find tutorials and software packages for the Raspberry Pi On www.raspberrypi-dmx.org . Following WiFi setup it resets and after some 10 seconds the led shoudl turn green. hay. If you don't please do so.

The frame refresh is actually not accurate, since reading from the web interface shuts down the refreshing. rll⸮⸮|⸮l⸮|⸮l⸮b|⸮⸮⸮⸮r⸮b⸮b⸮⸮nn⸮lnn⸮⸮⸮bp⸮⸮lrlrlp⸮n⸮⸮l⸮⸮bn⸮|l⸮⸮b⸮⸮nn⸮l⸮⸮l`⸮nnl`nr⸮⸮⸮nb⸮lr⸮⸮nb⸮l⸮l⸮p⸮⸮⸮⸮`⸮⸮n⸮setup starting You should write the content of the “data” directory as a SPIFFS filesystem to the ESP8266. I’ve got this working but I’m curious as to why there is a delay of about 3-4seconds before the light responds. but couldn’t print “data” or “global.data” (was getting error overloaded ‘print(uint8_t*&)’ is ambiguous) Tim. handleNotFound handleStaticFile /settings.html Great project, Robert! all computers on the local network receive them. No luck. To debug your setup, I suggest you keep the esp8266 connected over a serial interface and that you add some “Serial.println” commands to the Arduino code. Still no luck. But it doesn’t works always. In part that seems to cause the DMX serial protocol (i.e. /update.html, [SPIFFS] upload : C:\Users\TIMMAS~1\AppData\Local\Temp\build9256632f4e667cb638a4ee0f0e3880ee.spiffs/esp8266_artnet_dmx512.spiffs.bin setup starting the timing of ESP8266-controlled lightning. I have one question which was a bit difficult to figure out during my online research. Frame rates may range from 1fps to up to approximately 830fps. I tested with Resolume Arena, I saw that the packages were coming to the esp8266, but no response on the led strip. Thak’s Robert. I’ve set up my NodeMCU, AP cobnfiguration went fine, here’s the log: loadConfig setup done Or I think this…. If those are not broken out on your module, then I think it is quite likely that both are enabled by default (pulled high). *WM: Connecting as wifi client… The serial output shows that the wemos d1 mini receives packages, but the flood panel doesn’t react. Please try out both. Looking at http://arduino.esp8266.com/Arduino/versions/2.3.0/doc/reference.html it appears that it cannot be changed. Make sure you have selected a board, port, and closed Serial Monitor I have tried 2 lights, both on channel 1. That causes sendBreak() to be used instead.” For anyone using QLC+; ArtNet Universe is offset from QLC Universe by -1 as described here https://www.qlcplus.org/docs/html_en_EN/artnetplugin.html If it does not work, connect it the other way around. I’m assuming its a timing issue, but I’m so new to all this, I’m not sure where to begin. Update 4 July 2019 – You may also want to check out this instructable, which describes a more sophisticated ESP8266-based solution. handleStaticFile handleRedirect *WM: 192.168.1.2 These will be received by multiple ESP8266’s, which each individually forward it onto their DMX cable. Thanks, great project. Hello. 15:47:55.718 -> *WM: AutoConnect I just tested some more. else which may cause this problem? Do you have any advices for further testing/debugging? RS-485 uses signal lines “A” and “B” (see wikipedia). See the “include” directives in the source code files. Or in the onDmxPacket you could print them whenever new values are received. Could you try to confirm the issue with another DMX fixture? Some programming languages start counting at 0, some at 1. If not: if you scan your network with your computer or phone, you should see a SSID with the name “ARTNET”. There are also some simple-to-use Python packages (in case you are a Python programmer). However, what the “something” is, I don’t know…. Serial1.begin(250000, SERIAL_8N2); Thanks. How should I connect the MAX485 module to the led strip? I think it works? I want to shut it down with Home Assisant but at this moment, this isn’t possible. Is it possible to use it as access point , without using an existing network ? It adds a menu item to Tools menu for uploading the contents of sketch data directory into ESP8266 flash file system. The MAX485 chip has a “driver enable” (DE) and “receiver enable” (RE) pin, see the datasheet. Can someone help me with a ready HEX file for this project? Hello, I need to solve a doubt, after the first connection, I set up for the wifi and everything happens correctly. Bailing out. Thank you very much for all the efforts you have made for this project, and thank you for sharing it with us.

To allow a convenient interface between the EEGsynth and this type of professional lighting systems, I built an Artnet-to-DMX512 converter.
