Feature Request: Support for HUB75 display #1725
Comments
Firstly have you seen our FAQ question: So the good news is:
Which means if they have sufficient permissions beforehand it shouldn't need root access. I think there are two options here, it could be a standalone OLA client which just receives frames of DMX, or could be integrated into the OLAd core. The former is probably the easiest way to start. Although after more than 13x13 RGB pixels will hit the limits of one universe and sync type stuff is probably easier within the core (although would work, just possibly a bit more clunkily), outside it. See the sync ports config here for some details of sync considerations: Do you have the device and how's your C++ @freaknils ? TBH with this one you could probably get some code working in C++/Python or even Bash: |
I am sorry, I did not read the FAQ.
Yeah, I have got three devices, but my C(++) is really bad.
Thanks for the hint, maybe I will get this to work! |
No worries @freaknils . We've just been bitten in the past (such as #400 ) either by people disappearing after code is written and needs testing, or by issues that can't be easily resolved remotely/need too many round trips.
Are you willing to learn/try? We're happy to help. As you say it should be pretty easy given they do all the heavy lifting.
Please post here if it works, for others that find it. The only challenge with this approach is probably dealing with the multiple universes needed for any reasonable number of pixels. It's possible either way but may be a little simpler internally. |
It would be very cool, if OLA would support HUB75 LED (like https://www.adafruit.com/product/607) displays similar to SPI pixel strings.
There is a library (under GPL v2) for this display so it should be easy to implement: https://github.com/hzeller/rpi-rgb-led-matrix/tree/master/examples-api-use
Thanks!
