if you're using Processing, for example, and the OPC library, you can set the strips/pixels in your code layer to be independent "lines" and non-contiguous, even though the actual hardware thinks they're one long strip

Thank you! Very helpful!
Do you know if it’s possible to run 12 fadecandys on a single raspberry pi?
Stephen Marsh
@stephenhmarsh
@dsandlerm_twitter - i'm not sure the limits of your r pi but the fadecandy documentation explains what will limit you in general: https://github.com/scanlime/fadecandy#what-are-the-limits-how-big-can-fadecandy-go --- in micah's ardent mobile cloud project i believe they used 5 fadecandies off of one pi and a usb hub

Thanks again!

@stephenhmarsh
@dsandlerm_twitter -- welcome, glad to help. btw my understanding is that the power requirements of lots and lots of pixels starts to get a lil scary: https://learn.adafruit.com/1500-neopixel-led-curtain-with-raspberry-pi-fadecandy

Does the SK6812 addressable led strip work with FadeCandy?
I had wondered out loud in the live channel why there was not a 3v3 led module out in the wild
turns out there is (at least now)

@scanlime
that’s a 5V chip
the 3.2v is Vf for two of the led chips. data sheet still lists 5V as the supply voltage
i’d be surprised to see 3.3v RGB leds, the Vf is just too close to the supply to leave room for a constant current controller, you probably have close to zero headroom with worst case Vcc and Vf

Did anybody get an answer regarding working fadecandy with Ubuntu?

@Josephmanuel1989
With ubuntu (18) dont worked, i installed version 16 and worked without problem.

@dsandlerm_twitter
Awesome! Thanks for the tip

Hello!
Im developing an image that divides into 22 strips of 22 leds.
The fadecandy server lights up the whole thing, but for some reason when I connect to the OPC it doesn’t.
I copied the same file from the server but it won’t display the whole image
Josephmanuel1989
@Josephmanuel1989
What is the sample that you are openning in OPC?
with this example, all LEDs are off?
Can you post the configuration of server?

Just curious, has anyone used OpenOCD to program the K20 recently?
I'm normally an STM32 developer, so I'm still getting used to the K20, but it looks like there may be some issue with OpenOCD when the flash is read locked. I see mentions of a patch in the openocd config file, but everything appears to be completely out of date at this point.

@jabdoa2
is there some documentation on how to update the firmware of a fadecandy?
i want to fix the LUT update memory corruption issue (#112) but I don't know exactly how to flash the image. guess i need dfu-util. anything besides that? any hints?

Is fadecandy project dead?
Micah Elizabeth Scott
@scanlime
fadecandy has always been a lifeless corpse that some people find useful :D

@Al105
Being one of those people who've just started finding fadecandy useful ... I got Matthew Kessler's P5.JS websockets interface working on my test rig... posted small bug fix back to git hub. Not bad for a 'corpse' discussion in its 6th year?!
