Large 8 panel (64x32 pixel) display #16

Hey there, thanks for the question. Unfortunately the quick answer is "I don't know". I am not sure the Adafruit HAT can handle that many displays or how much power each needs. If you make any progress on this such as alternative RGB Matrix HAT that supports this many displays please let me know. A quick check on the Adafruit displays says the 4amps per display is when every pixel is lit - and there are very few display modes on this project that light every pixel. I may need to bite the bullet and order more displays to see how many I can chain together... |

@ChuckBuilds I saw a lot of the changes ur made in 2.4. I have a slew of ideas to try and improve the codebase, make it easier to modify, more sustainable, especially by multiple people if you're interested. Cause as I go through the code and the massive merges you're doing to main, it makes it hard to try and contribute. I am a software developer for work so I'm happy to provide best practices and ways that will make this easier. I want to contribute back but currently its very difficult and I'll just end up maintaining my own fork and do my own thing which i don't want to do. |

Sure, sorry for the mass changes. I am just trying to get things working
again after the last update broke other managers and displays.

I think I see what happened. After approving your PR's, I didn't add them
to my development branch - so when I went to merge with main they weren't
there. I am still learning git and best practices on all this, I apologize
for any frustration! I think I've got them all added back now, checking
deeper.

Interesting, I guess it could go either way. I don't think many of the
users of the display have ever used a github project before so I thought
keeping "main" as my best version for a new user to download would keep it
easy for them. I guess if we switched to the release model we would need to
use a :latest tag or something? Open to direction, I just don't know
better. Happy to talk it out on Discord too if these emails get annoying.
Thanks for the help, I really appreciate having a second set of eyes
involved. I hadn't had any merge requests until last week so I haven't
thought about this.

so it really depends on what ur "main" branch is. FOr all the projects I
work on, the main branch is the development branch and the releases are the
deliverable and if i'm supporting patches to released versions, i create
long lived "release" branches instead. This model prevents massive dev to
main merges and keeps everything clean.

That sounds messier. If the latest tag is automatic to the release and not
straight into main, let's do it your way and just PR into Main with a
branch for each effort of changes. I need to get better at smaller chunks.
Trying a rebase now then we should be good to go from here on. Thanks!

we can go either way, IF u do want to merge into Dev and then merge dev
into main, i still recommend using a PR to merge dev into main AND squash
the commits. That way it shows a single commit in main with all the
changes, there is still a PR that allows u to review everything that will
change from dev to main.... and its a lot cleaner history in main. Then
delete dev branch and make a new one off of main to start the process over
again and u could call the dev branch dev-2.5 then dev-2.6.....

Run the command “git pull” on your pi from the LedMatrix folder. I fixed
the flashing Spotify late last night.

Thank you both. I found that page and tried a temporary short with wire
and tape but after your comments I went ahead with soldered and that fixed
it.
Everything is looking good now except I am getting a flash on the music
(Spotify) screen. It must have to do with the refresh rate because I
changed it from 1 to 5 and that reduced the flash on the screen. Any fix
for that? I changed it to 30 for now.

I came across this repo and video today and it's exactly what I've been looking for. I want to make a large display, 4x2 panel display and want to make sure I get everything I need. For power at full use I'm looking at over 32Amps at 4 amps per panel but it sounds like ur doing fine with 2 per so that brings me down to 16. I'm thinking to get 2 of the 10A power supplies and split them so 4 panels (2.5A each) per power supply and then only power the pi and bonnet via the USB connector. Do u see any issues with that?? I'm also looking to get a ras pi 4, hopefully that should have enough resources to power all those LEDs. Anything else I should consider to make this work?
