Alles anzeigenI think you misunderstood the expression "blocks". Your calculation is right, but your result is the number of channels - not blocks!
8x64x3 = 1536 channels.
One universe has max 512 channels, a single pixels requires 3 channels (r,g,b). So 512/3 = 170,6.... So you can drive 170 pixels with one universe, that means you have to set channels to 510 (170x3). (Leaving the setting at 512 results in the loss of two channels you described.
Once you haved configured one device with its max number of pixels (170), driving more pixels than 170 requires additional universes. In your case: 1536/170=9,03... , that means you have to configure 10 devices/universes.
This makes patching a little bit complicate and you shouldn't expect your first attempt will make it - but it works fine, once you've got behind it.
Another option is using tpm2.net: you would configure only one device an patching would be much easier. But I don't know if this is an option for you.
tnx for your answ.
uhm, I suppose that my hardware controller is not able to use tpm2.net, but when i use XLights the system automatically split universe... but i will check better.
I understand what you told about channel, and I also configured to use only 504 channle (becouse 21x8x3 return 504) and i can use seimple rectagular part of matrix, but is like the last 2 pixel (504,505,506 and 507,508,509) are used the same and leave me 2 blank pixel.
For resolve this for now i did this (but only for test, is very slow to do)
20x8 starting from 18, device 1 with fast path
by hand pixel 3-8 with first channel of device 1
by hand pizel 1-2 with last channel of device 2
21x8 starting from 0, device 2 fast path
I solved but very stupid way.
I retry with changing the number of channel to 504 but as i told I already did
