Re: Outside Commercial use of RaspberryPi

Depends on where you are what the high and low values might be, but we have had Pi's running in the Antarctic, as well as deserts, so I suspect you would be OK with the appropriate protection.

“simplify” would've been shorter, as Heater noted … and we have so many Linux distributions purely because we can.
How about uncomplexify?

Re: Pi Is Too Complicated

From Debian. From Debian. From Debian. I'm struggling to understand the point of this post. The OP was bemoaning that because Raspbian is built on Debian it changes too often due to changes in Debian, and Jamesh's apparent rebuttal of that is to say the changes come from Debian. So you're in agreem...

Re: Pi Is Too Complicated

At risk of repeating myself (from another thread), the gist of the OP's complaint seems to be that things change, authors don't update their tutorials, and I have to find the solutions for myself. At risk of sounding like a troll, my question to the OP is this: Why not stop complaining at the wrong...

Re: Pi Is Too Complicated

I wouldn't say too complicated just too many changes to keep track of in the OS. But l don't think that's the RPF fault. The issue l find is getting all relevant details / documentation, it seems to leak out at times, normally in these forums. The OS itself doesn't change hugely* when looked at fro...

Re: Raspbian OS unreachable after several hours of use

My R-Pi3 seems to be doing fine with the old code cron job.......48 hours and still going strong. Seems to me then that the apps you have installed are spamming the logs, filling up the SD card, and the system fails due to lack of storage. This is an issue with the apps you have installed - a cron ...

Re: STICKY: PMs being turned off from June 13

OK, so it's all getting a bit silly. So in précis. We have turned off PM's on legal advice, because we cannot be sure it won't be used for inappropriate communications. This is down to the GDPR and COPPA. Since these are both new laws, there are very few test cases (if any) or precedent, so legally ...

Re: FBG : Framebuffer graphics library with multi-core support

Sure, it can be used to make anything related to graphics. However this library is very bare-metal (not specialized for video games) and graphics are not accelerated by the PI GPU, as such there might be better alternative for video games on the PI. :) Implement some of the primitives using NEON an...

Cool!
I'd like to put this into PINN. Would it be possible to build it into PINN/NOOBS's buildroot environment?
I'd be inclined to wait until testing shows no issues, then we will release it as standard anyway.

Will this work with DPI too or is it only possible to use HDMI and DSI? If yes, how to configure the timings in case custom timings are required for both, HDMI and DPI? Any display that is run from the VC4 side of things using dispmanx would work. Just set up the DPI display as you would before, an...

Re: Pi Is Too Complicated

Odd that people think the complexity is due to divergence from Debian. We try pretty hard to make as few changes as we can (because its a maintenance nightmare), so intrigued to know what these major usability changes/differences are. Networking was mentioned, but AFAIK, it's pretty much plain Debia...

Re: Repeated external USB drive corruptions

The Pi cuts power to USB too early for your drives, they are probably busy saving when the Pi reaches the end of shutdown and cuts power to the USB ports. Using the external automounter (autofs5) should solve this; systemd tries to stop the automounter early in the shutdown process, so the drives h...

Hello all, Finally got round to sorting out the multi FB support as a beta. This implements frame buffers for both HDMI/composite and LCD panels at the same time. So you get /dev/fb0 and /dev/fb1 if you have both HDMI and LCD attached. Here are the instructions to get the code and install and test i...
