Could you give us more information about the problems you've had, especially with launching opc-server itself? The demo pattern is shown when no input data is coming in via OPC, though it can be disabled. Please look at the help outputted from opc-server (-h) for more information about the various flags.
Given you want to drive 720 LEDs per strip, you probably want an opc invocation like this:
./opc-server --count 64 --mode ws281x
I am not aware of a 64 pixel limit in the processing OPC library, but it is worth mentioning that it has been adapted from Fadecandy which is designed for for 64-led strips, so there might be an issue. I'll take a look later when I have access to my test hardware.
We've used it for a few thousand LEDs, make sure that the OPC server on BBB is set up to expect the number of LEDs in your system ( led count , number of outputs etc)
and AFAIK, there isnt much change on the processing side other than making sure you send the right number of pixels the OPC server expects
I'm going to close this issue as I think it's something specific to the OP's environment. I'm aware that better docs and a simpler setup process would be good, but I think that's beyond the slip of this issue. @gsandreas please contact me directly, lightatplay@gmail.com, if you have any further questions, I would be glad to help, given the time.
Hi,
I want to use the BBB for powering in total 50Meters of LED stripes, seperatated in 10 parts with different lenghts which are not arragend in a Matrix. The longest has a total amount of 720 single LEDs.
I've worked with Processing and figured out, that there is a 64 LED limitation, which comes from the fadecandy implemtation. Is there any way, to use all capabilities (more than 64 LEDs per Channel) of the BBB with Processing?
Furthermore i made some experiments with shell comands to the opc - server and i could not get it to work. It shows always the demo pattern which i can not change.
You mentioned that there is a documentation available. Do you mean your readme.md in github? Unfortunatly i could only get the BBB to work with the demo pattern, and with your readme.md i could not find the failure i made.
