Re: Serving Hi-Res files to a DAC

Nice fresh overview of different DAC's here: https://www.whathifi.com/best-buys/hi-fi/best-dacs Seems like a lot of them have USB, which probably is very useful since the Pi doesnt have either Optical or Coax out. Which of them would be plug&play is harder to determine... ( google their name + Linux...

Re: FFMPEG lviestreaming to Facebook and Youtube

RTMP_Connect1, TLS_Connect failed
TLS is part of SSL ( OpenSSL ), it may not be directly related to FFMPEG.

Are you running an updated RPiOS Buster ?

You could still check by seeing what libraries you have under "/usr/lib/local" and search for duplicates.

Re: Does anyone have Kivy running on Pi4/Buster Lite

You should maybe run the "ldd" command on your binary to check that it is linking with the SDL2 you installed ( /usr/local/lib/ probably ) and not the standard SDL from RPiOS ( /usr/lib... )

I'm not completely sure why your phone mounted the card read-only.
The card-reader you used with your phone, can you use that with another computer ?
How did you burn the uSD card to start with ?

Re: I know there is a simpl answer - USB HD Question

MANY of the plug in fire up and immediately generate a mount error.
But what is that error ?

Kernel/system messages available with the "dmesg" command after you plug in the drive could also be useful.

Re: Using gps module for project

So the python in the link will have to be tuned to get it to work with my gps? Probably not, I meant that it will need some changes to print out the data you want in a way that looks good on your TFT-screen. Which then links back to my answer from 3/7 regarding how you choose to access that screen.

You havent really told us what you want to use it for. This program is very flexible and has so many available plugins that its unlikely two people have the same setup.

Re: Connect USB modem to pi4

I think you can put it anywhere in the file, on its own line of course..

You should see the debug when running the "pppd" command. Remove that option and I think you will not see much output.

You should not need the source of "pppd" if you have the manual: https://linux.die.net/man/8/pppd The option "persist" is something you should add to the "/etc/ppp/peers/quectel-ppp" file. Also just a note.. there is nothing in that guide that is EC25 specific, this is just a generic script that wou...
