I noticed that the Setup of NodeRED on Raspberry Pi still recommends BullsEye (Debain/PiOS 11). Pi ecosystem has moved on to BookWorm (12) and now Trixie (13). These OSes take advantage of new southbridge comm chip on the Pi5. Yeah, this has given us grief. I understand there is a software shim …

[image] SonoraTechnical: I noticed that the Setup of NodeRED on Raspberry Pi still recommends BullsEye That's just out of date documentation. [image] SonoraTechnical: To use NodeRED on Pi, do I need to stay on Pi hardware that is 1 generation behind and software that is 2 versions behind…

[image] jbudd: No you don't. You might experience problems with GPIO pins. There were reports of such but I think they are resolved by now. Yes, I am one of those that reported GPIO issues a bit more than a year ago.. well, i2c comms, which use GPIO pins. never got it fully working again wh…

The Raspberry Pi foundation only ever seemed interested in Python (in keeping with most education stuff I suppose) so node.js never really seemed to be of interest to them. [image] SonoraTechnical: I can only gather that NodeRED going forward just isn't interested in having new and improved rel…

So yeah - long story short - as you know they changed the Pi5 hardware and "broke" the old way of getting at GPIO. I did look at the new libraries - but they would then be pi5 specific and not backwards compatible - and given the large population of other Pi versions out there I didn't want to to br…

[image] dceejay: So when they made a compatibility layer available (rpi-lgpio) then in theory that should then allow the "old" nodes to continue to work. But as I said I don't have Pi5 so can't directly test myself - but hopefully someone in the community could do - and help update the docs if t…

Just a small comment, Pi 4s are still made and Raspberry Pi have committed to continue making them for some time (Jan 1st 2034) raspberry-pi-4-product-brief.pdf 600.81 KB

yeah... aware of that... just really liked the m.2 support of the 5. I have many 4Bs.... so certainly my projects can stay on that platform.

What do not have I think, is confirmation that libgpiod and node red work seamlessly together on a pi5.
