Re: Which /dev does the HQ camera use?

If using libcamera then you can add "dtoverlay=imx477" to /boot/config.txt to use bcm2835-unicam to get the raw image frames from the HQ camera ... Thank you 6x9. It sounds, from your description, that using the dtloverlay flag is the direction I'm most interested in. I want the raw image...

Thanks for the information folks. Hermann, that's a great thread! I would probably never have dug around in it based on the topic.

Re: PHP Version 7.X or 8.X

What way do you recommend to update from 7.3?
For 7.4 I'd uninstall 7.3, download, compile and install 7.4 from source. https://www.php.net/downloads
A migration doc: https://www.php.net/manual/en/migration74.php with some useful information.

Howdy folks. I think my question belongs here, if not, my apologies. I'm trying to capture output from the HQ camera and forward it in real time to another computer on my local network. The problem I have is I can't seem to attach my code to the right device. I thought it would be /dev/fb0 as it att...

Re: PHP Version 7.X or 8.X

I'd stick with 7.x for now. 8 is just being released and will probably need to get the bugs shaken out of it first. If you really want to get 8, then sudo apt autoremove --purge php then download the new v8 sources, compile and install. I've already compiled it to see if it would (it did). But I'm n...

Re: Need some more info about C

Which IDE should I use I suggest none. I've been writing C code for almost 30 years using a text editor and the command line for the most part. An IDE just gets in the way because then you have to learn how IT works as well as focusing on the actual language. Most of the code you'll create in the b...

Re: Why is Ubuntu so much slower?

Ubuntu desktop is the MS Windows of the Linux World. It's big and it loads a ton of libraries for the desktop. It's a good distro but it really needs some CPU and system RAM to shine.

If you want to run a fast and lean Linux OS, try lubuntu.
