So with great help from Frank aka on RuneAudio I have the power button working now.
RuneAudio is based on Arch so a little different to what I use to but simple to follow instructions for noob like myself Big Grin

Hope they would be able to make the OLED working

Hmmm.... Has anyone got a display working with xbian?

Thinking of artist, album, track no, track title, track length, track time incrementing, encoding and sample rate.

(Sorry Rikardo, not trying to hijack this thread but as the topic is here I thought I would ask). Smile

Don`t know, but should be possible: http://kodi.wiki/view/LCDs

@Nachteulee,

Thanks for the pointer. Today I finally got a 20x4 LCD working with a pi1 and the latest Xbian release.

I am very happy with this now, but need to spend more time looking into the xml settings and getting it all *exactly* as I want it. I so far have only customised the welcome and goodbye messages, but it looks like a lot of fun to play with......Track, artist, album,tracktime,date,day,time etc all working very well!

Smile

@Skywatch

Do you have i2c or 'parallel port' interface?

I'm thinking about a 20x4 i2s display for playing a little bit Smile

Skywatch · 30th Apr, 2016, 04:19 AM

I2C - I learned the hard way with arduino! Wink

Actually it is a 'normal' LCD with a I2C adapter soldered on the back (both bought separately).

**rikardo1979** · 12th Jul, 2016, 07:18 PM

I just bring this back again Smile

Question for our clever developers. Is it possible to install MPD on our system and than use it to play the music? And than maybe install the power management and display python scripts?

Debian has MPD package for installation, so it should be possible Smile

What do you mean with "install the power management" AFAIK RPI's does not support power management

Do you want to display anything via python scripts to which display Huh

LCD? HDMI?

I suppose LCD, however I don't think you'll find a ready2use solution for doing that on XBian, but should be possible Smile

if you read back at this thread you find I using Audiophonics I-Sabre DAC which has power management built in Wink

Works a treat in RuneAudio, Volumio, MoodeAudio Smile

You can see there is actuator push button fitted on front which is wired into DAC board. DAC board is powered by +6V(up to 9V) which is plugged to RPi over GPIO. So RPi is taking power through it. Which means your sound coming out of DAC is not affected by crappy regulator on RPi Wink

Also this DAC has own TCXO clock which is perfect(this is one of the main issues on RPi)

Display is OLED connected to DAC board again which is also running fine under RuneAudio or Volumio. There are some people who working on implementation into MoodeAudio too Wink

I know

But there is still the question what "power management" is

Usually PM means that system is able to going into suspend or hibernate mode, but this is not supported by RPi

Don't have such a board. I suppose this is done by hardware. This switch is turning on/off onboard power supply like a ATX PSU does

Btw, Hifiberry AMP+ also has power supply onboard and is powering RPi too, but can not turned on/off, it is always on

I'm far away from being an audio guru, my old ears can't hear any difference Tongue

AFAIK those pins are connected straight through from the RPI GPIO connector

in this case you can go ON/OFF by this PM Smile

So there are PY scripts to properly shutdown the system before it goes OFF. And than you bring it back ON by pressing it, so yes it is like ATX. Which is what I really missed on RPi

My ears are still good and I can hear a big difference in sound Tongue

Yes, is direct connection on the GPIO Wink

which is great clean solution
