Plugins

So steps taken for this module to run MPD_OLED on a x86

Install all dependencies:

sudo apt-get update
sudo apt-get install build-essential autoconf make libtool libfftw3-dev libiniparser-dev libmpdclient-dev libi2c-dev lm-sensors libasound2-dev autoconf-archive i2c-tools dkms

Get headers to perform make (will break ATO):

wget https://github.com/volumio/x86-kernel-headers/blob/master/linux-headers-5.10.139-volumio_5.10.139-volumio-1_amd64.deb
sudo dpkg -i linux-headers-5.10.139-volumio_5.10.139-volumio-1_amd64.deb
sudo ln -s /usr/src/linux-headers-5.10.139-volumio /lib/modules/5.10.139-volumio/build

reboot

Get driver:

git clone https://github.com/gschorcht/i2c-ch341-usb.git
cd i2c-ch341-usb
make
sudo make install

Check if loaded:
dmesg | grep i2c-ch341-usb

Add volumio to group:

sudo addgroup volumio i2c
newgrp - i2c

Build and install cava:

git clone https://github.com/karlstav/cava
cd cava
./autogen.sh
./configure --disable-input-portaudio --disable-input-sndio --disable-output-ncurses --disable-input-pulse --program-prefix=mpd_oled_
make
sudo make install-strip
cd ..    # leave cava directory

Build and install mpd_oled:

git clone https://github.com/antiprism/libu8g2arm.git
cd libu8g2arm
./bootstrap
mkdir build
cd build
CPPFLAGS="-W -Wall -Wno-psabi" ../configure --prefix=/usr/local
make
cd ../..  # leave libu8g2arm/build directory

git clone https://github.com/antiprism/mpd_oled_dev
cd mpd_oled_dev
./bootstrap
LIBU8G2_DIR=../libu8g2arm CPPFLAGS="-W -Wall -Wno-psabi" ./configure --prefix=/usr/local
make
sudo make install-strip

Configure MPD to copy its audio output to a named pipe
(Ignore the errors)

wget -N http://pitastic.com/mpd_oled/packages/mpd_oled_volumio_install_latest.sh
sudo bash mpd_oled_volumio_install_latest.sh
sudo mpd_oled_volumio_mpd_conf_install

Run MPD_OLED:
Check for the correct bus:

volumio@volumiox86:~$ dmesg | grep i2c-ch341-usb

[ 4125.761992] i2c-ch341-usb 1-1:1.0: ch341_i2c_probe: created i2c device /dev/i2c-14

Use correct bus number:
mpd_oled -o SSD1306,128X64,I2C,bus_number=14 -f 50

or:
/usr/local/bin/mpd_oled -o SSD1306,128X64,I2C,bus_number=$(dmesg | grep -iE "ch341_i2c_probe: created i2c device" | sed 's/^.*[/]//' | sed 's/.*-//') -f 50
