Re: RPI2 framebuffer not displaying fully

No, I actually haven't done anything with the VC. All I did was download the open source VC toolkit that's floating around and compiled a few of the example hello work programs. I didn't even run them actually. I guess what I was thinking is that with ARM64, it has a very large virtual address space...

Re: enable SSH access in raspbian-lite.img

And if you really want to make an image, you can configure the RPI, power it down, then image the SD card after your are finished.

Re: enable SSH access in raspbian-lite.img

Oh, I understand what your saying more. I think you need to wait until the RPI boots before you can enable that.

Re: enable SSH access in raspbian-lite.img

I just normally do "apt-get openssh-server". I known Raspbian has a custom control to enable it, but I'm not sure how it works at the moment and I don't have Raspbian available.

Just creating a file named that is really bad news.

Re: Error while upgrade and installing

I would generally avoid running a * patten on the archives directory. Who know what version you're gong to be pickup.

Sometimes the archive gets out of sync as new packages as added, so sometimes it's best to just wait awhile and try again.

Re: minicom for rangefinder

I really really try adding those resistors. A simple voltage divider should work fine for you. That is if the PI isn't already damaged at this point.

Re: Cheap [Arduino] pan/tilt system for Raspberry camera

Just out of curiousity, why are using arduno? The RPI 0 can already do most of what you are looking some. That way you wouldn't need to have a second processor to program. The RPI already has PWM for controlling servos and such. It has interrupt for measuring movements and such. And you could add a ...

Or maybe even use the camera for the RPI to take the pictures. Then wirelessly send them to somewhere like Facebook.

Re: nikon d200 wireless transfer

You know, one way you could do it is use the RPI to use USB to transfer the photos onto the RPI and then use some software on the RPI to post the pictures someone like Facebook. Then you could download them from Facebook onto you iPad. Or at least view them.

I have the same problem with cases the RPI. I don't like any of then. I bought a 3d printer that I use with free software called FreeCAD that's available on the web.

It just means I'm interested in codecs and such, which I honestly don't know anything much about through from an exact implementation port of view. Something like that might be a good thing to read up on.

Re: Raspberry PI3 Fan without a Relay switch

Sorry, I just noticed you said it has a built in resistor. You will have some issues with the pins of the RPI being 3.3V instead of 5v except for the power rail. So to use that LED, your going to need to use a transistor(probably a mosfet).

BTW, you know you will need to probably have a resistor in series with that LED, otherwise it probably won't last long.

Re: Raspberry PI3 Fan without a Relay switch

The Led thing depends on how complex or simple you want things to be. The simple solution is to just write a startup and shutdown script that runs when the PI starts up, and shuts off when it halts. If I recall, you do this through /dev/gpio. I think Linux has a user space LED driver library that yo...

Re: Mail Server Raspberry Pi

You don't have to open up port 25 completely, just have it redirect to a single machine the RPI. Just don't have something like dovecot running on the same RPI because it's a big target for people. Honestly, the biggest issue is that most ISP will filter the SMTP port in both directions so that you ...

One possibility is that something weird happened when you went to the website. I have issues with that from time to time on my Intel PC behind an expensive firewall/content filter. Usually I just blank out the PC and reinstall. Since the RPI has an external SD card, it should be rather easy to just ...

Sounds like a good idea.

And if something say were to go wrong with your SD card, you can just get a new one and you'll still have access to your files.

Re: rpi3b chrmnium play youtube, cpu jump from 4% to 230%

I typically have issues with youtube where I live and that's not on a RPI of any kind(Intel).

The biggest factor for me is to make the window a bit smaller rather then fullscreen if that is what you are using.

Lowering the frame rate can help as well.

I may actually know someone how would be interesting in creating such things.

As for as dealing with the legal issues, that isn't something for me to say. As far as I'm concerned I don't know anything that has really changed and why this would be a new issue.

Re: RPI2 framebuffer not displaying fully

Hi, I saw someone mention about 2GB. It is possible to change total_mem to 2048. I tried it and things boot in 64 bit, but I'm still seeing 1GB. Is that kind of memory actually available, and do I need to modify the DT to get it? Or am I just dreaming and need to go back to bed?
