I know E1.31 support is planned, but I'm going to lobby for xlights to adopt and use OLA for its DMX control.
OLA was built just for this kind of use, supports much more DMX hardware, and would allow xlight dev time to go towards other features.
Now there are two areas where xlights can give back to OLA - there is work to be done to get OLA working on windows - and OLA currently only recognizes commercial USB dongles not DIY.
Since my only interface is E1.31 - I can not use xlights currently. Anyway, Simon, lead developer at OLA is awesome and responsive and the library seems really well put together - it would be great to see those wheels not reinvented unnecessarily in xlights.
