@kristofferlislegaard You need [comport] at least and the patch I posted here (dmx.zip) will do it....... https://forum.pdpatchrepo.info/topic/12016/led-dmx-lighting (extended and vanilla I think)
The OSC messages are simply " /x value(0-255) " where x is the channel number.
It talks to the Enttec DMX Pro through a port.
The USB Pro is a pretty dumb device that just talks over a virtual serial port through USB.
It works fine on a laptop in Windows etc.
I had it working on a RPI2 under Jessie. I am pretty sure I installed OLA to get the FTDI driver working properly but I can't remember.
I am halfway through trying again on my RPI3 under Stretch.
There are problems to solve.....
The PI reserves the serial port (even for USB devices I think) for a TTL console..... and that must be disabled in the config.
Under Stretch the Bluetooth grabs the serial ports and that has to be disabled or "swapped".
