Henri from Mots Cousus released a new library for handling DMX messages in Processing, dmxP512. It is partially based on the proDMX library I wrote a while ago, but supports more DMX hardware (enttec DMX USB PRO and lanbox LCE in its first release) and also adds things like buffering to prevent network/serial congestion. So basically dmxP512 replaces proDMX, which I don’t expect to develop any further.
