Using libcamera is it possible to record video from all four cameras?

Not with the board you have. It's a simple 4 to 1 switch. You can pick a camera, and it becomes active. When you pick another camera, the first one turns off. Only one camera at a time.

Disable auto_camera_detection

This is what Arducam seem to recommend with all of their hardware now.

It's certainly the case with their ultra-wide fixed-focus IMX708 M12 120° module

Code: Select all

apt-cache search rexx

should show you that regina-rexx is a package that's available on 32 and 64 bit.

The launch of the 5 was also complicated by the priority order tokens available to MagPi print subscribers. From what I heard, these priority orders wiped out most of the initial allocation, so unless you ordered in the very first minutes of launch day, you're waiting for the second or third batch. ...

If you're going for a headless setup with read-only overlay filesystem (which you're probably not), please note that /etc/NetworkManager/ must remain writeable or networking will fail.

That was a fun one to discover ...

I was about to suggest something, then I re-read this: I have an RPI4 with raspberrypi OS bookworm 32 bit. On 64-bit bookworm Desktop ( not what you have), libgfortran5 (12.2.0-14) is pre-installed This might be a temporary lag in the (formerly) Raspbian repo trying to use its own version (12.2.0-14...

I'd make the watchdog shorter. The docs say: On rp2040 devices, the maximum timeout is 8388 ms. You're getting close to that.

Also, I see that you have a request that you don't close. Your script will run out of memory because of that

scruss

can recommend f3, too: though it is a destructive test

scruss

We found the cause. A colleague was vigorously scrubbing at the module with a microfibre cloth while the camera was powered on. This has a 100% kill rate on v3 cameras. Sorry about that.

MicroPython on the Raspberry Pi Pico doesn't support working as a USB flash drive. While some other MicroPython boards do (like the original pyboard), it's generally not recommended, as it's hard to keep the emulated file system and your computer's idea of the emulated filesystem in sync. Data loss ...

xfce-terminal has the same issues. I use guake, since it is a drop-down terminal.

The default lxterminal has always worked correctly for me:

However, there is no change in the terminal's output behavior after rebooting. Unsurprising, because it looks like you didn't install/compile the en_US.UTF-8 locale. Setting something in bash to a non-existent locale isn't going to help. sudo dpkg-reconfigure locales is what you need to run to side...

... it doesn't make sense Imager is a nice program that makes installing images easy for novice users. It is clear from your use case that you are *not* a novice user. Nothing's stopping you downloading any image and installing it via dd. Imager exists to help people have a good general Raspberry P...

This is the same failure mode I see with my Roku Soundbridge power supplies. It's a fairly old network music player with a VFD that draws lots of power. My Soundbridges "eat" a power supply every 3-4 years. I've always assumed it's an electrolytic capacitor somewhere in the PSU giving up t...

I noticed that while all graphical applications (I e. BlueFish editor, mousepad, etc) display Unicode characters, when such text is outputted on LXTerminal the Unicode gets scrambled, for example: ... Please show the output of this command: locale If the output lines don't include a lot of ".U...

... it only shows bullseye as compatible OS which is NOT TRUE as the p0w2 is compatible with both 32 bit and 64 bit bookworm It might be compatible, but I don't think it's recommended. Since the Zero 2W only has 512 MB RAM, the 64-bit Desktop is effectively useless on it. You can run Lite 64-bit, b...

Damien has dug in a bit and found that it seems to be caused by a bug in the RP2040 SDK itself: Alarm pool stops working under certain conditions · Issue #1552 · raspberrypi/pico-sdk. So it likely wasn't MicroPython's fault after all.

scruss

However, I then tried zxtune123, which is the CLI version of the program, and it's working! So I'm amazed that Pi is able to run software that doesn't appear to have been explicitly compiled for Pi, but it is good news. Yay! I think this is because zxTune statically links all its libraries in the c...

i386 libraries are for Intel versions of Linux. The Raspberry Pi uses ARM, which is incompatible.

This isn't going to work with what you've downloaded. Or, if someone suggests emulations, it will work very very slowly.

Your video is not viewable, but sometimes power supplies hiss. The inductors used in switching power supplies are often the source of noise. This is normal, if rather annoying.

Since there is still support for 68K and PowerPC Macs, … Both of these are effectively dead as Linux hosts. ppc32 (32-bit big-endian PPC) dropped off most distributions' support list some years ago. The only PPC branch seeing active maintenance is ppc64el, which only runs on IBM hardware. I tried r...

I tried to build it on 64-bit. It's currently failing with a lovely “ DSO missing from command line ” error, which generally means it needs more reconfiguration than I can manage. For those who'd like to attempt a build, at the very least it requires the qtbase5-dev and libboost-all-dev packages. Di...

Yes the 8th strip works fine - both the original and replacement one so it does appear to be a limit somewhere. Good to know. The capactor thing is a new idea. When you say a "great big huge electrolytic capacitor " I assume you are refering to the part where is says to add a capacitor (5...

not quite a schematic, but the pinout is documented in the GPIO usage section of the Audio documents.

Not all Raspberry Pi products have schematics.
