[PLUGIN] MPD OLED - installation & configuration plugin

Beowulf · May 29, 2025, 7:15pm

Hi, I would like to know if I can simultaneously add an oled static display with values of cpu, temperature, wifi, etc. to Volumio for Raspberry pi 4B. Thanks for the info and help, I’m starting with RPI thanks

Why, why, why you want to see all this on music “player”? Volume, bitrate, album, song, track I understand, but values of cpu?

On the main panel, only the song, artist, etc. On another small OLED display, these system values.

You can never have too much data

supercrab · May 30, 2025, 12:31pm

Yes, you can do this! Here’s how

Go to GitHub - antiprism/mpd_oled: MPD, Volumio, RuneAudio and Moode OLED status and spectrum display for Raspberry Pi (and similar) and download the source code
Make your changes to the code
Build
Copy mpd_oled to /usr/bin/mpd_oled
Restart the plugin

Install the plugin first and then go into the plugin settings, click on the I2C OLED wiring button and then attach the screen as per instructions. Once completed try the different screen types, one of them will definitely work.

Ok, will the oled show wifi, cpu, temperature? thanks for the help

supercrab · May 30, 2025, 6:52pm

The oled can display anything you like! Do you have any C++ experience?

here is a scribble in Python I’ve played with many moons ago. It’s just as starter. it’s untested and not supported by me:

i2c = busio.I2C(SCL, SDA)

# Create the SSD1306 OLED class.
# The first two parameters are the pixel width and pixel height.
disp = adafruit_ssd1306.SSD1306_I2C(128, 64, i2c)

# Clear display.
disp.fill(0)
disp.show()

# Create blank image for drawing.
# Make sure to create image with mode '1' for 1-bit color.

height = disp.height

I’m a beginner learning

Flowta · June 10, 2025, 11:05am

Hi guys, I have an issue with this plugin.

I installed it fine and works as expected, the problem comes when I restart the system.

It starts fine and screen comes on and shows time etc., but when I try to play music it comes up with this error

If I disable the plugin, restart the device and then enable the plugin again, then it’s fine

Wheaten · June 10, 2025, 1:24pm

Can you try to disable startup sound and /or mutliroom playback

Flowta · June 11, 2025, 9:09am

Thank you, disabling the startup sound fixed it
