Test sound

  • Wait until the LED When the leds are quiet again.
  • Reconnect * Open browser to http://moode/

Before making any changes check if standard supplied file 'Stereo Test' works.

  • In the library view select 'Stero Test'
  • Probably the volume of moode is default set to 0; set the volume to a normal level This file has a samplerate of 48k, so even if the 44k clock select of the Allo Isolator mod isn't applied, you should here sound.

Install mods and tweaks

Directory content:

  • mpddisplay - python app for OLED display with luma.oled + mpd2 client
  • softpowerdown - bring moode safe power down (requires hardware module)
  • systemd
  • tweaks -
    • starting with moode 7 - all the tweaks are one way or other integrated in moOde.
    • [switched to FifoPi] hifiberry-digi-pro-remap - allow 44k1 based crystal to be used with Allo Isolator (requires hardware mod).
    • [obsolute|integrated 6.6] moode_albumsearch_trim - strip whitespace before and after. ensures better search during live typing.
    • [obsolute|integrated 6.6] moode_albumyear - make the albumyear search priority OriginalRelease, OriginalYear, Date insteadof only Date.
    • [obsolute|integrated 6.6] moode_mpd_tweaks - Moode doesn't support all mpd options, with this tweak you can add in the mpd config screen.
    • [obsolute|integrated 6.6] moode_nativelazy_loading - use browser native lazy loading for album art by browser that support it.
    • moode_responsive_orientationchange
    • [obsolute|integrated 6.6]moode_sq_overlay
    • [obsolute|integrated 7.0]mpd_selective_resample - Patch MPD (tested on 0.21.20 and 0.21.23) to support selective resample and add it selectable to the Moode MPD version selector.
    • [obsolute|integrated 7.0] Show album cover on playlist

Some of the patches are already integrated and part of the moOde source tree.

Prepare install

Start ssh session (instead of using a client it can also be done in the webinterface of Moode in system configuration)

Get the mods and tweaks:

cd ~
git clone https://github.com/bitkeeper/dddac1794build.git
chmod +x dddac1794build/raspberrypi/software/util/*

Soft Power Download

add to /boot/config.txt:

dtoverlay=gpio-shutdown,gpio_pin=22,active_low=0,gpio_pull=off

Add service to start the overlay only when the system is fully booted:

cd ~
sudo cp dddac1794build/raspberrypi/software/softpowerdown/pipower.service /etc/systemd/system
sudo systemctl enable pipower
sudo systemctl start pipower

MPD Display

Enable I2C interface

sudo raspi-config
  • Select "3 interfaces""
  • Select "P5 I2C"
  • yes enable
cd ~
sudo apt-get install python-dev python-pip libfreetype6-dev libjpeg-dev build-essential
sudo -H pip install --upgrade luma.oled==3.4 luma.core==1.13
sudo pip install python-mpd2 gpiozero

vesion luma.oled=3.4 and luma.core 1.13 are required as later version will only work with Python3. Need to port this daemon from py2 to py3

Install service for display:

cp -r dddac1794build/raspberrypi/software/mpddisplay/ mpddisplay
sudo cp dddac1794build/raspberrypi/software/mpddisplay/mpddisplay.service /etc/systemd/system
sudo systemctl enable mpddisplay.service
sudo systemctl start mpddisplay.service

Moode: Change the number of visible albums on several device types

In 6.6 the scheme is changed, need new fix for 7.0.0

Instead of changing the original file, the new css media queries are placed in a separated file. This file will be include after the moode.min.css include.

cd /var/local/www
sudo cp header.php header_dev.php
sudo patch -b header.php < /home/pi/dddac1794build/raspberrypi/software/tweaks/moode_albumcols/moode_652_custom_css.patch
sudo cp /home/pi/dddac1794build/raspberrypi/software/tweaks/moode_albumcols/moode_additional_media.css /var/www/css/moodecustom.css

Or in case of development replace the last line by:

sudo ln -s /home/pi/dddac1794build/raspberrypi/software/tweaks/moode_albumcols/moode_additional_media.css /var/www/css/moodecustom.css

More responsive orientation change

In the header.php remove the orientation change handler.

Original:

<body onorientationchange="javascript:location.reload(true); void 0;">

New:

<body >

Prevent MPD scanning of cue files:

In the root of the music library create a file called .mpdignore with the following content:

*.cue
**/*.cue

Install of npm and development tree

Only required if your are going todo some development on moOde, else skip.

sudo apt-get install npm

Is about 60MB.

sudo apt-get install mc htop

git clone your_moode_repo_url

npm ci

pi@moodep4:/moode $ git config --global user.name "yourusername" pi@moodep4:/moode $ git config --global user.eamil "yourusername@users.noreply.github.com"
