This project is based on Robert Oostenvelds esp8266_artnet_dmx512.
It is not forked, but copied, as esp8266_artnet_dmx512 is part of the big repository arduino.
ESP8266_Artnet_DMX_DC is the extended version of esp8266_artnet_dmx512 mainly to implement dmxmapping.
- receive Art-Net data packets and output them to DMX.
- use dmxmapping to change values of the dmx channels in realtime.
This is called dimmercurve in many dmx softwares. - receive E1.31 / sACN alternative to Art-Net
- all features working in AP-mode
- firmware update by service menu
In addition i added checks for artnet sequence, which is important for all sorts of animations.
In UDP communication packets might change their order.
When sequence is not checked, movements can make unwanted jumps.
If monitor shows too many sequence errors, maybe check your network configurations and dmx software settings.
Calling the web interface might create sequence errors, as the other functions stop for a short time!
- universe: universe for Art-Net / sACN. For both cases the first universe is 0.
- channels: number of dmx channels to transfer to serial output. Default is 512.
- delay: delay in milliseconds between dmx transfers. Default is 23 for 512 channels. Thus the refresh rate will be about 40 Hz.
- useMaps: global setting for activating mappings. 0: deactivated, 1 activated
- mapChan: if useMaps is 0 and mapChan is not 0 then the mapChan value is the dmx channel, that is watched to switch mapping on and off according to the value of the dmx channel. If the channels value is smaller 127, mapping is off, otherwise it is on.
- startDelay: time in seconds, that the device will wait for the connection to the router to come up.
- e131Start: if e131Start is 1 the device will also receive sACN data, else it will only receive Art-Net.
- e131Unicast: if e131Unicast is 0, sACN will receive multicast, if 1 it will receive unicast data.
- ap-psk: if ap-psk is not empty, this is the psk for ap-mode. If it is empty, the psk is the reverse part of the mac-adress in ssid.
With the menu Show map files in the service menu you can have a look at the existing map files.
The menu Upload map files allows it to select a map file and upload it.
A RGB-LED shows the different states of the esp device:
- RED: not connected to WLAN, error reading configuration, short before reboot
- YELLOW: success reading configuration
- BLUE; web server called
- MAGENTA: no artnet data for more than a second
- GREEN: everything ok
When calling the web interface, dmx output might stop for some seconds.
Thus do not call the web interface while using the esp-dmx-device for a live show!
On the first start you have to connect to the open WLAN access point ARTNET_DC_<PartOfMac>. The PSK for that net is the reverse <PartOfMac>. Now
- enter or select your SSID and
- enter the password / your PSK.
After rebooting, it will connect to your WLAN.
For security reasons starting the wifi-manager to change network settings is only possible after pressing the reset-button 2 times. The wifi-manager will appear, if the device gets no connection. To force the wifi-manager to come up even if the device is connected, press the reset-button at least 5 times. Using PersWifiManager there is no forcing. PersWifiManager is called by the menu.
