Smooth interpolation for DMX
Sep 16 2013 | 7:45 pm
Hi guys! I'm controlling lights with the enttec/dmx usb pro. When I change the color of the fixture directly on the values (R G B dimmer) it's ok. But when I try to interpolate it with the pattrstorage I get a horrible flickering result. Does anyone have a clue on how to smooth this values coming from pattrstorage?
- Sep 16 2013 | 7:54 pmAre you sending the values inbetween the presets? For instance, if you want to interp. between preset 3 and 4 you need to send3. 3.0001 3.0002 3.0003 ... 3.998 3.999 4If this is what you're doing, then perhaps showing the relevant part of the patch would help a lot.It could also be that you're transmitting other (noise) signals out of the enttec, which is causing the confusion. Pattern interpolation with dmx is entirely doable with the usb pro. :)

- Sep 16 2013 | 11:00 pmThank you @wetterberg, that's good news then. Yes, I've going thru all the floats. @floating point, do you mean refresh or baudrate? And why when I move the values outside the pattr system everything is ok? Here's the patch:
