Re: Specification Object Detection Model

Are we talking OpenCV, TensorFlow or what ?

I think with a Pi4 and 4GB you can more or less disregard hardware limitations and rather pick the model that suit the objects you want to detect.

Re: Neo-6M GPS update faster than 1Hz

You download the documentation for your module to find the "string" you need to send to your GPS to change update frequency and maybe also baudrate. Or you google it.. https://forum.arduino.cc/index.php?topic=470763.0 https://medium.com/@cglabs/neo-6m-gps-howto-boost-data-receiving-speed-neo-6-neo-7...

AFAIK there are versions of Kivy that can use the OpenGLES accelleration on the Pis, so it can run accellerated fullscreen apps.

Kodi has a ton of add-ons under "video" that can stream from a lot of web-sites but of course you will not get the same freedom as with a browser.

Re: Rc522 RFID scanner gives Errno 2 error

Code: Select all

 python3: can’t open file ‘Write.py’ : [Errno 2] No such file or directory
This is not a very cryptic error it tells you clearly it cant find the file.

Either you created/edited a file with a different name by accident or you are not standing in the correct directory when you write the command.

Re: Streaming on the Raspberry Pi

LibreElec running Kodi would be my tip towards the best performing mediaplayer. ( IDK if they are fully supporting Pi4 )

But if that doesnt perform then we have to ask about networking performance, how is the Pi connected to the internet.

Re: NFC tags in raspberry pi

Have you ever used another NFC module?
I have, but they are usually USB based and I haven't usually done card-emmulation with them.

I dont know enough about I2C to say if your problem is with the PN532 itself or just the I2C communication. ( which goes back to why I prefer USB devices.. )

Re: FTP Permissions

How can i change the permissions of files and directories on the foreign FTP Server?
You send an email to the person that runs the FTP-server.

But also it would be good if you first describe what problem you have where you think changing the permissions is the solution.

Your blocker will eventually become the processing delay introduced in to the sound. And your TV most likely doesnt have a picture delay function.
There is a reason these things are done in dedicated hardware.

Re: Docker questions

Docker provides convenience scripts at get.docker.com and test.docker.com for installing edge and testing versions of Docker Engine - Community into development environments quickly and non-interactively.
You will get newer versions than the one in the Raspbian repository.

Re: Website access via Wifi but not Ethernet

Somewhere in the config for the web-server there is a setting telling it which IP address to "listen" on. If that setting is "0.0.0.0" the service listens on all available network interfaces. eth0, wlan0 etc. If that setting is just the IP-address of one of the interfaces then it will only listen on...

Re: Rotate HDMI on boot to command line

Are you using a Pi3 or an Pi4 ?

On Pi3 and older models there are options in /boot/config.txt for rotation.

Re: Ctrl-Alt-Del confusion

There is a chance that upgrading will not change the already configured behavior and only a new install from scratch will have the new default behavior.
It would be the polite way to do it IMO.

You should check how much of the current 1GB you are using before you splash out on a new Pi.

"htop" is a nice command to install, shows the memory usage a bit better than normal "top".
