Hi Adrian,

I've implemented a new feature whereby you can disable the equaliser when the player is paused with the -e parameter This is useful if you're using the mic input as the audio source of the equaliser with -c alsa,hw:5,0 When the player is paused, CAVA takes the noise from the input and slowly normalises the data so that it fits the entire graph, even though there is nothing playing. I simply clear the array that holds the spectrum data when the player is paused.

Main.cpp attached:

main.cpp.txt

Just wondering if there is a chance to make this working on the latest RaspDAC Mini running moOde?
Display used in this kit is an SPI OLED but not sure what make or model.
I may take it apart and check if needed

Thanks in advance

I want to thank you for you great work with oled screen ;)
I have one problem and I don't know how to fix this. Spectrum bars doesn't work:/ I attached photo how it looks now. Can you help me?

Edit: ok spectrum bars doen't work only with Volumio spotify plugin. With radio stations it works fine.
Any solution?

Dear Adrian, is MPD_Oled compatible to Volumio snapcast plugin for multi room solution?
Currently my Raspi pops up failure while activating the plugin and later on the volumio player has malfunction.
Thanx for your support
Benjamin

I'm trying to compile on a gentoo aarh64 (arm64) system.

but it gives me this error, does it depend on the 64bit system?

Hello dear developer,
man thanks for your code 👍
Have you planed to integrate Spotify and Airplay?
thanks

Hi,
advance thanks for the great application. My compliment !
Now my two concerns.
Is it possible to switch Spectrum analyzer in full screen mode, or to change over a little change of the source code.

Furthermore, my question is it possible to implement a peak hold.

Best Regards
Peter

Dear Adrian, I use an Raspi 4 with Volumio. All is working on the latest software. Now I found your really cool project. Unfortunately I am not so deep into Linux, but copy and paste is working well :-). I bought the following Display: 1,54 ZOLL OLED128X64 SSD1309 which should be compatible with SSD1306
https://www.ebay.de/itm/253369133648
The display will not work, after several days of work. I think I need your help.
I read all forum content in the different platforms, but without success.
I cannot use I2S because the port is already booked and running with a RTC. I checked the 1.54 SSD1309 OLED Display function with an Arduino project from my coffee machine and the display is working there when I exchanged it from its old 0.96 SSD1306 OLED from the first moment.
Ok, back to the Volumio DAC:
I activated the SPI function in the config.
I configured the display as following on the Raspi GPIO (Pin No is mentioned not GPIO No.)

OLED Pin - Raspi Pin
1: GND - 14: GND
2: VCC - 9: 3,3V
3: SCL - 23: SPI SCLK
4: SDA - 19: SPI MOSI
5: RES - 22: GPIO 25
6: DC - 18: GPIO 24
7: CS - 24: SPI CS0

I set your code to Adafruit SPI 128x64.
"sudo ./mpd_oled -o 3 -b 10 -g 1 -f 20
The Installation guide from you did work fine until the following lines:

"If you have a reset pin connected, specify the GPIO number with mpd_oled -r, e.g. mpd_oled -o6 -r 24 .... (For, SPI OLEDs, edit display.cpp to include your connection details, if this works out I will provide options for these parameters.)"

Please can you support me?
I have no clue how to configure the last needed settings.
Your manual is wonderfull for a rooky like me until the last lines. Please, can you write on the end of your manual clear commands?
Is my Pin setting on the GPIO wrong?
Where and How can I configure these settings in your code?
Did you try out the SPI display or did anyone tried this out with success?
What further data do you need for support?

Currently my display is completely blank and there is not poping up only one pixel :-)

Thank you in advance and best regards
Benjamin from Frankfurt

Hi @antiprism

thank's for your work already.

I need to tell that I some how stuck before I got things running. I made a fresh install of moode 6.5.2 to have a clean start but still my display doesn't light up. I followed your setup instructions exactly and there were no errors at all which leads me to the last possible reason: my display is not supported?

I have this type of display

Found this link online (my version is only single colored): https://www.rhydolabz.com/displays-c-88/096-oled-bicolor-display-spii2c-128x64-6-pin-blueyellow-p-2262.html

The thing with this display (which supported I2C and SPI) is that it is shipped as SPI (4SPI?). I have no equipment to change it to I2C and also want to profit from the higher refresh rate for SPI.

The display has only 6 pins and is missing CS pin. Otherwise I wired exactly like you describe.

I tried various display settings (most importantly -o 1 and -o 7 I guess).

Is there any hope to get this display running in "stock" setting?

During a reboot or shutdown the display remains on, it is possible to respond to the sigterm and display a reboot system instead of the clock, or simply reset the display

Hey, first of all thanks for the great work.
For a lot of use cases in a home network it would be very handy if one could read the ip adress of the device on the screen. It could be shown very small in one of the corners.

I will fork this project later and work on this. Any tipps how to implement this?

Is it possible to run your program with the following display?
https://www.waveshare.com/wiki/1.5inch_OLED_Module

Another question for a possible perfection of your software. Switch over the display via an mpc trigger so that you can see the songs in the current playlist and then scroll through them to select one of them.
Like for example on the console with ncmpc

Regards Peter

Is it possible to adjust the brightness of the screen?

Weird one: I'm receiving this warning whilst compiling warning: 'auto' changes meaning in C++11; please remove it [-Wc++0x-compat]

and the build fails due to the use of auto keyword for defining state in main.cpp:444

hi,

have tried getting mpd_oled to run with an sh1106 spi. seems like more work is required to make it work correctly. to sanity check have used luma.oled's example apps. this does work, so the wiring and other setup is correct.

have checked that the basics (RESET, DC, chip select) is correct. have also updated oled_is_spi_proto accordingly.

do you have any specific idea on what needs to update?

Hello antiprism,

Using Cava to drive mpd_oled as instructed here: https://github.com/antiprism/mpd_oled/blob/master/INSTALL_VOLUMIO.md
Had two working raspi volumio environments, did fresh install to ver 2.502. Audio is lost after running make statement.
Bug report at: http://logs.volumio.org/volumio/o1cRaUm.html
This is the output when it breaks:

Cava used to bundle a copy of the iniparser library, which was used when following the build instructions provided with mpd_oled.

This library is no longer bundled with Cava, and the mpd_oled instructions to build Cava will fail unless the iniparser library is installed. This was reported through #28

For now, the OS instructions are as follows

MOODE (DEBIAN BUSTER)

sudo apt-get update
sudo apt-get install libfftw3-dev libasound2-dev libiniparser-dev
git clone https://github.com/karlstav/cava
cd cava
./autogen.sh
CPPFLAGS=-I/usr/include/iniparser ./configure
make
sudo make install

VOLUMIO (DEBIAN VERSION BEFORE BUSTER)

sudo apt-get update
sudo apt-get install git-core autoconf make libtool libfftw3-dev libasound2-dev
git clone https://github.com/karlstav/cava
cd cava
git checkout -b pre_iniparser_removal 3cc2f9f
./autogen.sh
./configure
make
sudo make install

RUNEAUDIO
I cannot test, but try the following to install the current version of Cava.
Install the iniparser library package:
pacman -Sy iniparser
When configuring the Cava build, If the usual plain './configure' fails then try:
CPPFLAGS=-I/usr/include/iniparser ./configure

Alternatively, install an older version of Cava

cd ~
git clone https://github.com/karlstav/cava
cd cava
git checkout -b pre_iniparser_removal 3cc2f9f
./autogen.sh
CC=clang ./configure
make
make install

could this great piece of software be modified to display only selected information?

My idea is to support more displays. I would like to use

• left dispay for left channel spectrum analyzer
• center display for song, artist, clock and other text info
• right display for right channel spectrum analyzer

Idea of using cheap displays is great, but those displays are so cheap, that using more of them can provide much more comfort and fanciness :-)

Sorry for placing this to "isssues", I did not found better place for feature suggestion.

Hi!
At first, great work!!!
I want to use mpd_oled with a 256x64 SPI SSD1322 Oled.
I got the driver File with all adresses ready, but im not sure how to implement it.
In your tutorial for Volumio you have made this quote: "(For, SPI OLEDs, edit display.cc to include your connection details, if this works out I will provide options for these parameters.)"
When installed, there are 4 Files named "display", ending on: .cpp .h .o and display-info.h .
I think that i'm able to fill the adresses and parameters, but i don't know the dependencies, or in other words: i don't know in which files i've to change what....
I hope you could help me to solve this problem,
best ragards!

Thank you for excellent plug in. Easy installation, works grate on moodeaudio.
Is it possible to replace current time on main screen with elapsed song time ?
Thank you.

Does this install can be done also on Volumio system image?

thanks

Take care!

Is there a way to switch between 12hr and 24hr format? Tried changing the code in display.cpp, line 79 to
strftime(str, STR_SZ, "%l:%M:%P", now);
and reran install.sh but there where no changes. This is in Volumio.

I have problems with instaling this oled screen https://allegro.pl/oferta/wyswietlacz-oled-0-96-ssd1306-blue-arduino-spi-i2c-7636893024 Can somebody make video how to install this oled on raspbeery pi (I have rpi 3 b)

i'd follow all steps and working almost fime...
so.. i have a slow refresh on oled display (ssd1309) , expecially if i use GPIO2 and GPIO3
after moved to GPIO 5 and GPIO6 (overlay of i2c) run more smooth but not perfectly..
and another issue is delay of spectrum from music... it doesn't match and display delay about 2 sec.

my config is Moode audio with RP 3b+ without Dac board

Hello!

Is it possible to install the service as it is without the spectrum visualiser? On rpi 0 w the installing of mpd_oled makes the device respond laggy, and I believe is from the spectrum part.
I think the older versions were without the spectrum. I only need song info and clock screensaver when nothing is playing. It's doable?

Thank you for your support on volumio community

Best regards,
Catalin

This plugin is great, I already made it works.
But seems it does not support none-English song name display, like Chinese/Japanese. Is that possible to support it?

Thanks.
Harry

It took me quite a while to get this working but I was able to, but when I click play the graphic EQ starts up and seems to be working (sometimes I have around a 9 second delay before it starts), click pause, bars keep moving for about 12 seconds... I have tried 2 versions of volumio and both do it (latest and 2.413)

do you have any idea what might be causing this?

Hi again,
I just notticed that in iddle state, network icon next to IP address is overflowing - far right 1px column is rendered far left, row just below the first.

Everything else works normally, so this is just a small cosmetic glitch.

Successfully installed for Volumio, with the following issues

1. I'm unable to sync the spectrum with the sound. I've changed the #buffer_time in /volumio/app/plugins/music_service/mpd/mpd.conf.tmpl significantly higher and lower, and resaved audio, and it seems to make no difference?

2. Seems to be a missing linebreak in mpd_oled.service after [Service] which prevented the service from working, gave "Failed to execute operation: Bad message" error. Fixed with manual editing!

Hello,
I'm getting an error as I try to make CAVA.
I'm building this up on top of the Volumio installed on a Pi zero W.
With very little knowledge about programming, I'm at a loss how to solve this.
What should I do?

Following is the message I got.

Makefile:792: recipe for target 'install-recursive' failed
make: *** [install-recursive] Error 1

to get the mpd_oled to be enabled on power on in Runeaudio+R rather than putting an entry for i2c-dev in /etc/modules you need to create a file in /etc/modules-load.d. eg. i2c.conf, with the entry i2c-dev.

I would have the following question: which tff do you use as the basis for your excellent code. I have a script that let me IR remote control the current IP address show us sysinfos. For this I stop via a script the mpd_oled service and show 10 seconds the info. Thereafter, the mpd_oled service is restarted. That works quite well so far, but unfortunately the fonts do not match yours.
Many thanks in advance

Peter

I have a device that is supposed to support 64 lines, but displays much better when asked for 32 lines.

Running on Pi0w v1.3.

Everything compiles OK. No equliaser for Spotify.

It would be nice to rotate accros 2 or 3 ways of displaying the information so as to avoid burning pixels. If the same time zone or track zone is displayed constantly the screen will "damage" those zones.

Please repost the connection diagrams or include a test file that states how to connect the wires from the display to the Pi.
Original links in guide are not working (at least not from Poland)

Thanks

Hello again,
I tried to implement screensaver by entering -S parameter to mpd_oled. I had a partial success, but now, I'm stuck and kindly asking for help

Basic idea was simple - if player is stopped, paused (or unknown) and -S parameter provided, mpd_oled should draw "draw_screensaver" function instead of "draw_clock".

-S parmeter should toggle "screensaver" variable to "true", which initialy set to "false"

My problem is - it does not switch it. When I compile it with "true", it works as expected, but I cannot get switching by parameter working. I think this will only need some small tweak, but this is my first try to programming and I still do not understand all syntaxes fully.

main.cpp:
main.txt

Maybe you can find this usefull too. It willl save OLED display life, and also provide darkness for sleeping if you have your player in a bedroom.

Hello,
I am using this plugin since I my first Raspberry - 3B+ with volumio on it. I have installed display at the beginning too! I love your work.
The only problem is, I must reinstall it everytime after Volumio get update, as Volumio is checking system integrity.
Is it possible to make your plugin an official Volumio plugin to install it simply from repository?

Thank you,
Michal, Slovakia

Is it possible to show the web station radio name on the display.
Using a 4 pin I2C SSH1106 display.

Firstly - I recreated a new build as old sd card was getting a bit messy and introducing audio dropout on mpd. This said the output of bars was clean and perfect.

Move forward to this week, reinstalled everything on a fresh build and getting this jitter effect. Cava seems to build cleanly, output of make on mpd_oled :

Don't know if the build characteristics have any bearing on this jitter, or whether something is carrying forward from cava. Any variables you need - point me in the direction to give them to you. The jitters are bars that dont represent audio but flick fully on (full amplitude) anywhere on the spectrum and generally in quiet spoken word (radio broadcast). The rest of the display is perfect. Tested on an option 6 SH1106 and option 3 Adafruit 1.3" and both the same - its not the displays and as I say - not evident on old SD card - all same hardware.

I have a video of the issue I can mail drop to you.

Firstly thank you for the nice work and the detailed installation. I have tried it on RPI Zero. The display was flickering. The upper part of the screen has some overlay of date and other data which I am not sure. Please see attached photo and video.

Hello.
There is an interesting display module FYSETC Mini12864 Panel, controlled by SPI ST7567 (same as UC1701).
Is it compatible with the mpd_oled ?
