Re: Problem to solve - playing 4K film with RPi directed actuators

As you suspected, 4k is too much for the Pi. It is limited by its hw decoders to 1080p60.

Hmm, this is an odd one. We've not seen any issues with the new wireless firmware in our testing, and the majority of people seem to be running ok, so it's going to be difficult to track this down. So far it seems that hidden networks and/or IPv6 may be partly responsible. Anyone have any other clu...

Re: Showing a Pi can replace a standard computer

Pi server or any sort of remote desktop might be worth it, as people can use that to access faster servers if the Pi itself isn't fast enough.

Re: raspberry pi foundation charity donation via facebook

I would be suspicious of anyone offering to pass through your donation to a charity. At the very least, they will probably take a cut for the "service". At worst it is a complete and utter scam and they'll take all of the money you "donate" for themselves, no matter who you intended it for. If you ...

Re: Touchscreen touch area (still) wrong

I've checked in a fix for this to our 4.14 tree (and our development 4.15 tree), and it should be in rpi-update fairly quickly, a few days at most I would think. Meanwhile, if you have the problem, follow the advice above.

Re: raspberry pi foundation charity donation via facebook

Can I suggest finding a smaller, more local charity? Whilst we are happy to accept donations, the runaway success of the pi means our coffers are well stocked, and I can certainly think of some smaller and poorer charities who would benefit from your donation.

Probably not Oxfam right now though.

Re: Touchscreen touch area (still) wrong

We've just found and fixed a bug in the touchscreen driver device tree entry in 4.14 (which you will have got with rpi-update) which I think is causing this.

Re: over clocking the pi zero W

I ran the stress package while monitoring both temperatures and actual CPU clock rate, and it stayed at 1100 for a few hours and maxed 52°C, without even so much as a heatsink. So yeah, there's something going on with this chip that isn't heat-related to cause problems at clock rates over 1100. The...

Might be worth moving to 4.14, or just updating to the latest wireless firmware (rpi-update).

Also, have you tried the instructions here? https://www.raspberrypi.org/documentati ... s-point.md

Sounds like you need a pull up resistor on the GPIO's. Either external (ie an actual resistor) or set the internal pullups.

Re: RPi2 Source Code for learners

We don't use u-boot so there is no source code available for that.

What part of the Raspberry distribution are you interested in with regard to source cod?. There is an awful lot in the standard Raspbian so you need to be a bit more specific.

No idea, but i suspect there are controls in X windows to reverse coordinate systems. Might be worth a google.

If it was running at 100% it was probably at 1100MHz. Not really. Lets use imaginary numbers for the purpose of demonstration. Say the Pi0 can compute 1 thing per second at 1100MHz, but it causes 100% CPU load Its likely to get hot, thus activating the Pi's thermal throttling which brings it down t...
