Re: Help please - can't log in to desktop as Pi after reboot! Again?

Hi, no. All I did was reboot. It's not that the pi user password is wrong - I can log in with it over ssh or from another terminal session (ctrl-alt-Fn). I've changed passwords with no effect. I can't do it whilst on the desktop - as the problem stops me from getting there. In searching I see lots o...

WD Pidrive - problems

Hi all, How do you use a WD Pidrive Foundation Edition as a normal Raspbian boot drive on a Pi3 without still having to use an SD card? I've set the OTP bit and validated that it's set, and also checked that after that I can boot from a USB stick with Stretch on it. The Pidrive appears to work OK us...

Re: how can a raspberry pi run a script thaat continuously reads a single file for changes and saves on itself

Or alternatively periodically running "rsync" may do it for you, particularly if you don't necessarily know what files may be generated that you want to keep a copy of on the pi.

Re: Capacitive Keypad...colour/cover?

Thanks.

I thought it probably should be possible to cover, but wasn't sure with what or what the limits where.

Pimoroni was totally unresponsive to the question, so I didn't buy it in the end and ended up buying just an MPR121 elsewhere and connecting the inputs to nice round ended coach bolts.

The definition of "HAT" makes that impossible. If you can stack them then they're not HATs.

Re: Best hardware for your Pi3?

Yes, pointless. To work correctly a power off switch for a pi would have to issue a shutdown even for the pi and then monitor the result, then remove power once that has been successful. I've seen a few examples of this such as the one in the link below. https://blog.petrockblock.com/2015/07/04/powe...

Re: Best hardware for your Pi3?

That switch will just cut power to the pi. You would need to shut down the pi before using the switch, to avoid the possibility of corrupting the sd card contents.

Being in the UK we have switches on sockets, so I either use these or pull out the plug after properly shutting down.

OK. I give up. I'll grab a new copy of the distro and fight my way through reinstalling everything.

I'd like to see an official specification for hat-like boards that can be stacked - that specifies a way to get the best possible stacking where this is possible (probably more around using the different serial bus options than general GPIO): pin usages/I2C address selection/pullup-downs etc
