I wasn’t able to run the nodeDmx examples by Tom because of some strange error related to the serialport library. After attempting to re-install the library in many ways, replacing the dmx default one (version 2.1.2) with a more recent one (version 4.x), Koji pointed out that my version of node was 7.x and that they (Tom and Koji) were using 6.9.5. So I installed the nvm package from the AUR and following his advice, I did the following:
$ nvm install 6.9.5 $ nvm use 6.9.5
And then I could run the example.
I still have to try with the USB to DMX converter… To be updated
