First we need to change over completely to systemd (which might be the future anyway), as Ingo has explained here: apt update && apt -y full-upgrade systemctl mask networking.service dhcpcd.service sudo mv /etc/network/interfaces /etc/network/interfaces~ sed -i '1i resolvconf=NO' /etc/resolvconf.conf systemctl enable systemd-networkd.service ...

As you are told by systemd: zfs-import.service is not a native service, redirecting to systemd-sysv-install. Old style SysV init system is deprecated and not used anymore. For compatibility it is only emulated by systemd but there are limitations. Look at Compatibility with SysV. If you encounter problems with SysV emulation then the first step should ...

You are asking to delete the unneeded and malformed file "/etc/apt/sources.list.d/brave-browser-release-.list". On the command line just execute this command: rpi ~$ sudo rm /etc/apt/sources.list.d/brave-browser-release-.list

This seem to be a misunderstanding. The usage of GPIO by the main and auxiliary SPI devices is as follows. MISO MOSI SCLK CE0 CE1 CE2 Main SPI 9 10 11 8 7 - Aux SPI 19 20 21 18 17 16 If you want to use the auxiliary SPI with a non-standard chip select you will have to toggle the GPIO yourself. This is straightforward. Set ...

Are there options raise and lower the priority/speed of normal background sync If you read man 3 sync, you'll notice "The writing, although scheduled, is not necessarily complete upon return from sync()", meaning the kernel makes this determination. While fsync(3) does block until completion, the priority of the request will remain the same. This probably ...

If you want for some reason (multiple captures audio etc...) You can adapt this schematic (thank's to bitluni's lab): replace 3V with 3.3V output of raspberry GPIO 3.3G (your microphone needs to support more than 3V, otherwise adjust the resistors). You now have a MONO microphone and a TS connector (very clear drawing, the AMP part). For me, I have an old ...

I believe there is no audio input on the Raspberry 3B+. You will have to find a hat to put your Piezo microphone, or go with USB… It's difficult to make a Audio input as it requires a efficient and fast ADC to convert the signal and this is not something present on the Raspberry 3B+. Note that USB may have latency compared to GPIO HAT based solutions. But ...

Raspbian has a service that updates the date and time automatically, but your raspberry has to have internet connection. As the raspberry doesn't have an external/power independent clock, every time you turn off your raspberry, it will record the actual date time. When turned on, it will assume that the date and time is the last recorded, but it will not ...

What are you doing with this Pi Zero ? If you're doing some project without connection to internet or just locally (home automation, etc) I would say no. If no big bug endangering your project has been corrected it may no be worth the time and effort required to put again in place your project. Now, if your Zero is hosting some web server, everything ...

I encountered this problem under Jessie. To solve the problem, I used : strace linphonec and getting the .db path, then : touch /path/file.db To check the sound cards (when you have resolved the creation of the .db file and linphonec want start) : linphonec> help linphonec> soundcard list 0: ALSA: default device 1: ALSA: bcm2835 ALSA 2: ALSA: ...

The Raspbian project does not build nonfree packages. Some nonfree packages are available, but they're just the cross-platform ones imported from upstream Debian. If you need to install it you'll have to build it from source.

This is due to the fact that you are computing RMS (Root Mean Square). There is nothing you can do against that and it will always be (unless you opt for a different type of circuit). To have the resulting RMS equal to zero means the signal coming from the CT is a perfect straight line. However there is always a tiny current change on the divider that you ...
