Re: Documentation for beginners

Hmm, I rarely use the mobile site, so that might be a bit more complex. Since our webteam seems to spend more time on the mobile site than the main site, that seems a shame.

Re: Multiple Frame buffer beta testers wanted

Thanks for the report. You should defo. see the rainbow screen. Or do you mean you have turned it off? Odd that underscan cannot be turned of, I don't see that. omxplayer does not play to framebuffers, it's a superimposed display of a display. When I tried it I could specify the display OK, so I mus...

Hm. I've obviously missed something, but there again, someone has got it working. Hmm indeed. I'll have a think, but might need to wait for Monday for fixes.

Did you rpi-update to the commit id specified?

Re: -b 30000000 crashes camera

30MBits/s is way too high, 17-20 should be more than adequate for 1080p30. To me, it sounds like you might be running out of disk space, or simply going to fast for the SD card to keep up.

Probably Python, although C would also work. Depends on how fast you want it to go.

Re: Do not buy this case, it has broken 2 brand new Pi 3 B+ devices

Sounds like it is putting pressure on the top of the SoC, probably breaking the PCB underneath. Did it come with various thicknesses of thermal pad for that are of the case? SImilar designs use different depths of pads to compensate.

Re: Multiple Frame buffer beta testers wanted

Bit of a toy application but could it do two frame buffers for SPI LCDs? These have reasonable pixel/inch, so tiny VR headset? https://www.adafruit.com/product/3787 They also have low pixel count so frame rate should not be too bad. I seem to remember stereo display coding was possible? Or eye anim...

We've sold millions of 2's and 3's. If there was a big problem with the USB hardware (underlying SoC USB is the same on ALL models of Pi), I think we would have noticed by now. The fact there is ONLY a problem with this particular stick and this particular driver indicates to me that its that stick...

We do not guarantee any particular third party USB device will work, mainly because we don't design them or write the drivers for them so will probably not be able to fix them anyway.

Stack is being corrupted. You have a couple of arrays on the stack, so likelihood is that you are going off the end of one of the those arrays. Print out some of the counters as you are looping, along with incoming string lengths and the lengths of the strings from the file to get more information. ...

Question: are the frame buffers always assigned in the same order, e.g. HDMI before DSI? So far my HDMI screen is always assigned fb0 and the RPF LCD fb1 I put in some specific ordering code, so could be in the order people think is best. I thought I had given the LCD priority, perhaps not. Will ch...

Thanks for the replies guys. The project is entirely about monitoring the production process and plant, it would not interfere directly in the assembly line

Rather than supply a link it might be more beneficial for those people to provided them with a link to something which describes how to use search engines. They'll likely be even more grateful long term.
