    Getting started with GPIO, using "new" gpiod interface

    in Beginners

    Posted

    (I feel a simple shell script with gpiod commands, ex. gpioset should suffice for my very basic needs here)

    Whereas Python is an interpreter language too, right?

     

     

    Apart from that, I read on below Github:

    including the official ODROID-XU4 wiki info about pin numbering

    • Cross platform MMIO GPIO that doesn't require one off code for each board. Only a simple property file is required to map registers.

    Sounds to me like do it once for me and the armbian community (sending in your findings), but I may be totally wrong.

    Security cameras

    went with Motion which is terrible

    I would like to have audio too (a bird cam), but if you only want picture and don't mind using RPi and the corresponding camera (no audio): https://github.com/kclyu/rpi-webrtc-streamer  

    Motion Detection feature provided by Rpi-WebRTC-Streamer uses Inline Motion Vector which is generated during video encoding. And use this to get the approximate Motion Detection function while using minimal CPU resources.

    I spent hours trying to get a Logitech c310 USB UVC compatible camera running, but UVC helps, but is not the solution to everything. IP-Camera may help or solve a lot?

     

    or the original: https://github.com/mpromonet/webrtc-streamer   almost at the end of the readme.md: Object detection using tensorflow.js

     

    Where are you with your project by now?

    Can I speed up boot?

    Does anybody have a tip about that?

    Well, systemd offers some diagnose options: 

    systemd-analyze time

systemd-analyze plot > RockPi_boottime-$(date +%Y%m%d_%H%M%S).svg

systemctl list-jobs to see active jobs

     

    Please take a fresh install to do the test - not to miss any improvements.

    Need your help - what else beside Etcher

    and now etcher so:

    I don't know how to understand that. However, I am more than happy with USBImager :wub:

     

    I read in the PDF manual about adding my user its group and now not even sudo is necessary to launch it. By the way, new release and this time with the .deb image https://gitlab.com/bztsrc/usbimager/-/releases  and if you run  man usbimager  you see some switches for more functions.

    Hello again,

     

    any progress on that front?

    I might try it out on an old C2, to get a feeling of how it compares to the other ones.

     

    You won't believe it but Paperless-NG (a thing I thought about it myself) is born: https://github.com/jonaswinkler/paperless-ng  and it sounds promising: https://github.com/the-paperless-project/paperless/issues/711

    Apart from that, this large PR has finally received approval and the author wrote me that your problem should be fixed within as well: https://github.com/the-paperless-project/paperless/pull/652

     

    You think this is enough, no!! there is more: https://github.com/eikek/docspell  a new project (around 12-14 months) but sounds interesting too, Scala 41.8%    Elm 41.7%  programing language.

    Last but not least, I haven't looked further into https://github.com/ciur/papermerge he wrote once he is working full-time on it, but if he doesn't make any money from it and there is no active community around it I guess it will sooner or later go down the same road as paperless.

    Using acronyms feature

    It is actually not the same

    Sorry, read it on the mobile - had an answer in my mind, but wanted to write on the PC and forgot it :(

     

    Well, both are no longer supported. So, when you  change an SBC from Supported to Not-Supported - it doesn't matter for the user whether you call it  EOS or CSC - to this person it is the same.  No supported images.

    As soon as someone steps in and want to support it again - its status would change to "supported".  As it is anyway on best effort - there is no difference at all. The EOS/CSC never made any sense.

    but got lost. 

    are you kidding me - this is as easy as it gets.

    Download a file from here: https://yadi.sk/d/_rQgn_FosYuW0g/20.09/20200911  flash your SDcard.

    1. Once finished, put the SDcard into your PC-Cardreader and adjust this to your needs:   The file "/extlinux/extlinux.conf" 
    2. All Amlogic models now look for the "u-boot.ext" file.  For your device make sure you rename this file:  =>  For s905x and s912 - use   u-boot-s905x-s912   to  u-boot.ext
    3. Put the SDcard in your TV-Box and power it

    Now you will be on the bleeding edge

    Hi Steven, can you please update your initial posting (a line at the beginning or such)  and maybe the last post so people find your great work?

     

    Edit:

    I see you already did.. but just a link. How about some words like: The improved version you find here:  ... obviously I stumbled over it, sorry.

    Edit2: 

    The link mentioned above is dead like a parrot https://www.youtube.com/watch?v=vZw35VUBdzo
