[HELP] AUDIOPHONICS I-Sabre V3 DAC ES9023 TCXO

[rikardo1979]

Hi

Do you always surrender that soon?

edit:I forgot to mention, I using Raspberry 2

You do not have the latest image for the RP2 / RP3, or?

Is your display wired correctly?

Frank

well, is not so soon. I spend £150 for piece of s.. as Audiophonics messed up big style sending a wrong parts in it, they support is one of the worst I have ever experienced and after a week of fiddling with, this crap still does not work...
So yes, I gave up and I have lost my nerve with this

[rikardo1979]

seems that Audiophonics was busy last days or hours

So for me that is the only solution, sorry guys...

Sorry to hear that Rikardo, but I will look for your posts in Xbian, when I am there desperately looking for information myself...

any time but hope you would not need any help with XBian. It should be pretty trouble less but you never know

Hi Bruno,

One thing you might guys me to figure out is where to call the script 16x2_oled_runeaudio.py so it runs when my Pi starts?

I would do it the arch linux way and use systemd.

Save this as /usr/lib/systemd/system/oled.service

Code: Select all

   
[Unit]
    Description=Audiophonics OLED Service
    After=mpd.service

    [Service]
    ExecStart=/usr/bin/python /usr/local/bin/16x2_oled_runeaudio.py
    ExecReload=/usr/bin/kill -HUP $MAINPID
    KillMode=process
    Restart=always
    RestartSec=10
    StartLimitInterval=30
    StartLimitBurst=20

    [Install]
    WantedBy=multi-user.target


Enable it:

Code: Select all

systemctl enable oled.service

I will have a look a it and try this week-end to add a few features like the detection of the airplay mode.

All the info is accessible via redis (activePlayer, act_player_info)

Code: Select all

redis-cli get act_player_info
"{\"volume\":\"40\",\"repeat\":\"0\",\"random\":\"0\",\"single\":\"0\",\"consume\":\"0\",\"playlist\":\"109\",\"playlistlength\":\"313\",\"mixrampdb\":\"0.000000\",\"state\":\"play\",\"song\":\"312\",\"songid\":\"313\",\"time\":\"748\",\"elapsed\":\"3\",\"bitrate\":\"1336\",\"audio\":\"48000:24:2\",\"OK\":null,\"song_percent\":0,\"audio_sample_rate\":\"48\",\"audio_sample_depth\":\"24\",\"audio_channels\":\"Stereo\",\"changed\":\"playlist\",\"currentartist\":\"moe\",\"currentsong\":\"George\",\"currentalbum\":\"Live at Snow Ridge Ski Resort on 2008-08-31\",\"fileext\":\"flac\",\"radioname\":null,\"actPlayer\":\"MPD\"}"

You can use redis-py for the script.

Can anyone use that script with the correct display module, or is it specific to the Audiophonics DAC?

I was going to use an I2C display because it does not take up any additional GPIO pins, but if this one works with Rune and Arch, I might as well make use of it (shrug).

It looks to me like the script reads information from Rune, and has no interaction with the type or make of DAC used.

[hondagx35]

Hi Pete,

it doesn't read from Rune but from mpd.
This is the reason why you will not get info when playing spotify for example.

So to summarize, here is how to make the OLED 16x2 works on a Audiophonics RaspDAC V2 (I-sabre V2 DAC ES9023) with a Raspbesrry 2 (be aware I'm talking about RaspDAC V2 not V3) with RuneAudio.

First wired the RaspDAC and the OLED like shown in this page:

tar zxvf RPi.GPIO-0.6.2.tar.gz
cd RPi.GPIO-0.6.2
python setup.py install

get the python script and uncompress it

Code: Select all

tar zxvf 16x2_oled_runeaudio.tar.gz

copy this file

Code: Select all

cp 16x2_oled_runeaudio.py /usr/local/bin/

Register the script as a service, to launch it at startup:

Code: Select all

nano /usr/lib/systemd/system/oled.service

Copy the following in the file:

Code: Select all

   
[Unit]
    Description=Audiophonics OLED Service
    After=mpd.service

    [Service]
    ExecStart=/usr/bin/python /usr/local/bin/16x2_oled_runeaudio.py
    ExecReload=/usr/bin/kill -HUP $MAINPID
    KillMode=process
    Restart=always
    RestartSec=10
    StartLimitInterval=30
    StartLimitBurst=20

    [Install]
    WantedBy=multi-user.target

Enable the service

Code: Select all

systemctl enable oled.service

Start the service

Code: Select all

systemctl start oled.service

Many thanks Franck!
If I have forgotten something, tell me and I will add it.

Hi Bruno,

thank you for this detailed How-To.

If I have forget something, tell me and I will add it.

Looks as it is complete.

Can these instructions be used for LCD display (not OLED) that is HD44780 compatible ?
