hey..
first of all really cool project!!!!! and thx for uploading it!!!!
im very interested in using the artnet4j lib in my project!!!!
ive checked your repository and i found the artnet4j.jar file in the lib folder!
i couldnt find that file in the
artnet4j lib repository! did you generate it yourself or am i just missing sth here!
im trying to use the artnet4j lib in processing and im having some troubles with it! i have problems with the
ArtNetDiscoveryListener... i have an enttec datagate mk2 connected via ethernet cable and i get following message:
