Audio-Distros: DietPi + MoodeV4Beta9 (automated install-script)

so,
Fourdee over at Dietpi->https://github.com/Fourdee/DietPi made a script for an automated DietPi + MoodeAudioV4B9 install..
works here (RPI3B + I2S-ES9028Q2M) fabulous and with absolut no issues (install/compile about 35-45min)..
„Skript“/infos are here->https://github.com/Fourdee/DietPi/issues/1223

„Currently in testing, under RPi Stretch.
Steps to test the DietPi + moOde installation:

Download the DietPi Stretch image and write to SD card: http://dietpi.com/downloads/testing/DietPi_RPi-armv6-(Stretch).7z
Download the following automated installation file http://dietpi.com/downloads/conf/moode/dietpi.txt and save it to the SD card /boot/dietpi.txt. This will automatically install moOde on 1st run.
Connect Ethernet.
Connect HDMI if you want to see the installation process.
Eject SD card, pop into RPi and power on“

(PS.: its then „dietpi/“ in the browser-line and not „moode/“ and the ssh-login data is: user=root and pass= dietpi)

DIY: STM32F103C8T6 („Blue Pill“) + Oled (TFT-) Display..

okay,
bought some STM32F103C8T6 („Blue Pill“) of about 1,55€ (1,72$) !! at Aliexpress->Link
thought i could use it for my planned own DIY-DAC to display input-source, samplerate, filter-settings, volume etc..

also a 2.6 “ TFT (240X320)->Link (Youtube-Vid is with an 0.96 OLED)

 

 

 

you can program/flash it with a Raspberry Pi->Link, no need for a usb-ttl adapter or ST-Link or something..

so, and with this Arduino IDE u can write some little programms/“sketches“ and write/upload them directly to the chip..
now i must a find a way to read out some information (from maybe a XMOS-USB-Bridge) about the samplerate for example, or maybe which input (USB (I2S), opt, coax) and write it out on a display..
but super no clue at present !! 😉 , i´ll inform you here about some progress..

UPDATE: MoodeAudio V4 Beta9 + ES9028Q2M (chinese-board) (DoP)

okay,
got here after a few updates Beta9 to work..
tried a lot, but with at present only „Generic 2 I2S-hifiberry-dac“ settings available and without the advanced or realtime-kernel i got only max 192khz over the bus..(with this ES9028Q2M)
so i fiddled a lit bit around with the DSD-settings, and it was only „DoP“-possible (see pictures) (not native DSD !! afaik – but have no problem with that here) with this board + actual settings but u have to set „Sox resampling=enabled“ and „DoP=yes“..curiously with sox resampling disabled-> no DoP !! (just for info)
DoP -> „yes“:

(DoP „no“->then no native DSD also->only PCM):

(rem.: it displays „DSD“ anyway->its related to the file (extension)) 

(Update: Moode V4 Beta9 as 2.6GB compressed to 920MB image here->Link (Google-Drive))

New ES9038Q2M Chinese-Board – pictures..

here are btw. some new ES9038Q2M-chinese-board pictures..
the board-layout seems to be changed to 1.04 and you can see how you can apply a input-selector switch to this..
(connected to JP2 and JP3; as described earlier and again on picture 3)
(basically you can do this too with another selektor on the other pins, so that u can change the different digital filter settings..(FIRs))


(Beware: according to some sources 0=Connection , X=Disjoin !!!)
(ES9038Pro+TFT Console->Audiodesignguide->Link)

OP-AMPS CHANGE (PART 2)->NE5532 to Muses8920->different, more musicality, very soft..

okay,
this time i changed the onboard NE5532 from the ES9018K2M to Muses8920 and the result is:
Different 😉

first, absolut no comparison to the OPA2604 (in any case to those i had here)->they were really bad..
These Muses8920 have a great musicality, and a very fine resolution but at present it lacks of something (in comparison to the NE5532)..
(so, here i have stop for a moment, because i have to re-check them in a few days..)
more to come…

MoodeAudio **FREE** !! (FOSS-license) Version 4 Beta 6 – RPI-3 (+ES9028Q2M)

absolute fabulous !!

Moode-Audio Ver.4 Beta 6 is now available via:
http://www.moodeaudio.org !!
problem is u have to compile/set it up more or less by yourself..
U only get some moode-audio-files (.zip) but has also to download debian-stretch-lite and make/bring it via a lot !! of shell-commands to work..
For me it took about 4 !! hours..
so for this reason, i decided it to upload the SD-Card-Image (about 2.5GB) to „Google-Drive“ (for other, not so „Linux-Enthusiasts“ 😉 )->use „Win32DiskImager“ or similar to write it to SD-Card..but be careful its under the GNU GPL-free license !!
Debian-Stretch-Lite->LINK (orig. Raspberry.org)
MoodeV4.0Beta6-files(+recipe)->LINK
(Update: thx to someone over at the MoodePlayer-Forum Link here is an Image of Beta9 at Google-Drive-> (2.4GB compressed to 918MB)-> Link (Google-Drive)
(rem.:this is the so called „BASIC/no extras“-Installation, without wiringpi,rotary-thing and without additional components (u can install them then by yourself)
so, Settings for the ES9028Q2M (for now):
got only „RPI-Dac“ to work; but limited to 192khz as said..“Hifiberry-DAC“ only works with mp3/: ->flacs->horrible noise..(if in 16bit->try to set min. 24bit in „MPD-Settings“)
try to check more options->post it then here..
Installed squeezelite too, and for the first time, NO loud clicks by switching from 16/44 flac par example to 24/96 or 24/192..

ES 9028Q2M + STM 8S103F3

hi there, just read here:->
„it seems that there is already an MCU fitted (ST’s STM 8S103F3) programmed to allow access to some of the es9028 internal hardware functions (volume etc)…“
->LINK
(additional link->LINK)

guess on the „newer“ ES9028Q2M´s (layout „2017 04 09“) there is this STM 8S103F3 and there is also a 4 pin header (5V+, SWIM,GND, Reset) to program/read out them..(SWIM-interface)


so, now is the question if someone has ever read out that eeprom (on these boards) or re-programed (and with what ?)..
any comments here concerning this topic are really,really appreciated !!
