DIY: First tests 2.6″ TFTLCD (320*240) Arduino UTFT-library..

so, 😉
see above..absolutely „low“ 😉 , but as test->UTFT-font is: „GroteskBold32X64“->

„wait,wait,wait..but for what ?“ 😉

(i will try to use some bitmaps/icons in future (like in the hifi-duino-project) but at present its really difficult for me to „include“ them/set them up in the sketch, also because of the very low ram-resources on an arduino (on a NodeMCU v3 for example u have up to 32MB flash and not max 256kb!! like on an Arduino (Mega2560))-there are some ways to optimize it, but for now i´m glad to got it to work at all 😉 )

ES9038Q2M/ES9018K2M: DSD (+PERFECT BITSTREAMING) WIN8.1-FOOBAR2000 (PART 3)-> DoP (352k) works !!

so, 😉
because „Krunoslav“ (again 😉 ) send us a link „Foobar 2000 for Dummies (Part 2) – Playing DSD – New SACD plugin“->
i updated my Foobar2000 to the latest SACD-Plugin+DSD Soundprocessor (V1.10-> and followed some steps to set it up..
so, first: got it to work !! but only at present here via DoP (352k) with the Skysong(Singxer)-USB-bridge+ES9038Q2M (via I2S)..(it doesnt matter for me that it isnt DSD-nativ right now):

second, first musical impressions: relatively „dry“, very low latencies i guess..have to hear here more..(but it could be more in another „league“ (DSD vs PCM))..
so, third, i fiddled a little bit around and here are now the settings which worked for me: (there could be other possibilities/ways as said)

first under „preferences“->“output“ i choose „ASIO:DSD Transcoder (DoP/Native)->

then under „output“->“ASIO“->“ASIO Drivers“->“DSD Transcoder (DoP/Native)“, double click on it and then (which is strange, because normally this Singxer-ASIO component didnt work at all until now)->“Singxer USB-Audio Device“ (no other ASIO-device works btw.)

fourth, also strange, under „preferences->tools->SACD“->“DSD+PCM“ + „352800 (PCM)“ but with „DSD Processor: None !!..“

as said, there could be other possibilities too but for me its enough for now and, as said, 2 strange things: The ASIO-Singxer-USB-Audio component works and DSD-Soundprocessor on „off“ too..(but the latter could be a little bug)..
so, and now it works here really great 😉 ..this DoP/DSD-nativ-thing is sometimes really in a different league (but that really depends on your DSD-material too)


so, 😉
thx to „Krunoslav“ again, he sent us some new driver (V4.38 from to test perfect bitstreaming via wasapi under Win8.1+Foobar+Skysong(Singxer)-XMOS-USB-bridge+ES9038Q2M->see comments->
unfortunately it doesnt work here for me but i will upload it to the forum anyway (LINK)..but be careful i had here very great problems with my antivir..
but curiously after installing my buffer-/“stuttering“-problems with files above 16/44,1 (now here in 24/192 no problems) with the Skysong(Singxer)-XMOS-USB-bridge+ES9038Q2M (via I2S) are gown away 😉 ..

but still these new ES9038Q2M (in any case the pcb i have here->the „blue“ one) sounds for me still like plate/sheet..(„old problem“->we still have to evaluate if its a „shitty“ pcb/components and if the „green“ ones sound better)..

DIY: Relay-controlled source-/filter selection ES9038Q2M (Arduino)

so, 😉
because i´m really stupid and really don´t know how to accomplish a „jumper-substitution“ and after reading in some Arduino-forums, i came to the idea of buying some relay and try to realise it via this way..

(Update:profd“ from the forum told „us“ to use digi high or low + a logic level converter instead;->LINK)
These relays are cheap, around 2€ or so, u can buy it as 1,2,4,8 and so on..they are really easy to connect/addressable..

(remark: the 3 wires on the right are for the 10k poti (and then in future for the digi-poti of course))

u connect the GND and + from JP1 on the ES9038Q2M to COM (GND) and NO (+) and thats it..(i first connected it to the NC (normally closed) but that means, if u shut the Arduino down, then the circuit is (normally-)“closed“, means jumper set..

the relay itself is easy connected; GND from the Arduino to the GND and Power (5V+) from the Arduino to the VCC-pin (the jumper JD-VCC etc.. is another story, only remove and connect it to an external power source if u want to separate the Arduino-circuit completely from the relais circuit).
IN1,IN2 etc. is connected to a pin of your choice/assignment made in the sketch like this:
#define RELAY1 8
#define RELAY2 12
#define RELAY3 6
#define RELAY4 7
(i will post the modified sketch in the forum->LINK)
so, and now i can control/set the source via the BT (via our sketch), means for example „c“ for coaxial, „o“ for optical, „i“ for I2S and so on..

if (a==’c‘)
BT.println(„Source: coaxial“);
digitalWrite(RELAY2,HIGH); //R2 OFF
digitalWrite(RELAY1,LOW); //R1 ON
lcd.print(„Source: coaxial“);


i, u, can also use this now to set the different-filter-types, as for example JP3=set and JP4=set ->“slow minimum roll off filter“)..(will also maybe make a modified sketch for this future..)..
so, and really funny/cool 😉 is that these relays really make a „clack“-noise, everytime u adress it, for example i choose „c“=coaxial it makes „clack“ and it changes to coaxial..

really „Hi-Fi“ 😉


DIY: 2.6″ TFT-LCD (320*240) SPI ARDUINO MEGA 2560 *MCUFRIEND* (Part2) **works**

so, 😉
got the above mentioned 2.6″ tftlcd finally to work !! 😉


see this (Part1)->
and this new post in the forum->
the „breakthrough“ was via this site->
(i got the chip/controller ID:“0x0404„)
and this very,very important,modified library->

(more, full article/post/tut in the forum)

DIY: Migration sketch/build-up Arduino Mega2560 to Uno R3

so, 😉
hello, nothing new in today my „Geekcreit® UNO R3 ATmega328P“ for roundabout 3€ (i order there sometimes because of (in general) faster shipping times then Aliexpress)->

nothing special, except u have to use „Pin3“ instead of „Pin9“ on the Mega2560 for irsend..
(made a long post in the forum->

greets 😉
