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

so, 😉
hello, nothing new in particular..got today my „Geekcreit® UNO R3 ATmega328P“ for roundabout 3€ (i order there sometimes because of (in general) faster shipping times then Aliexpress)->
https://www.banggood.com/UNO-R3-ATmega328P-Development-Board-For-Arduino-No-Cable-p-964163.html

nothing special, except u have to use „Pin3“ instead of „Pin9“ on the Mega2560 for irsend..

ES9038Q2M: interesting new forum (audiodiyers.hu) + DACES9038PRO

so, 😉
came here by chance to a new very interesting ES9038Q2M-forum->
http://audiodiyers.hu/viewtopic.php?f=48&t=3615
some interesting pics/news on it, par example that the Green 1.06 has 7805 instead of 7808 on it and so on 😉 ->

by that, there is also a link to a 9038Pro-DAC (DACES9038PRO) designed by Andrea Ciuffoli/Quang Hao + a lot of interesting infos around the schematics of the sabre-chips->http://www.audiodesignguide.com/DACES9038PRO/

 

greets for now 😉

ES9038Q2M/ES9018K2M: DSD (+perfect bitstreaming) Win8.1-foobar2000

so, 😉
because i have here heavy „overdue delivery“-problems for some Aliexpress/China-manufactored DIY-things (yesterday a Electric Soldering Iron arrived exactly after 94 !! Days), i decided to make a new try in DSD-(native)-playing under Windows..experiences so far:
(i used Win8.1 because i don´t want to fuck up my Windows10-settings with the XMOS-USB-driver)..
okay, i used foobar2000 (JRiver trial period is over 😉 ) and have here the Singxer-V4.36 driver installed..
I used the ASIO-tutorial in the Topping NX4DSD v4.14 driver and manual pack (->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=22) because i heard absolutely nothing with the „ASIO-Singxer USB Audio Device“-settings under „Preferences->Output->Device“..


after installing the foo_dsd_asio and foo_input_sacd foobar components + Asioproxyinstall v0.72 from the Topping V4.14 pack i´ve finally got a heavy white noise on both channels with the ES9038Q2M (and very very silent music back in it) and heavy white noise only on the left channel with the ES9018K2M (both with the Skyong(Singxer)-USB-bridge))..
The Singxer USB-Audio Device Control panel displays (in this case) 5644800hz and foobar also shows:“DSD128/11290kbps/5644800hz“ and the DSD-light on the ES9038Q2M and the blue DSD-led on the Skysong are also lit (see picture above)..

i´ve read elsewhere exact the same behaviour/problem..
okay, but this is a small improvement, because with the normal „Asio-Singxer USB Audio“-driver i heard absolutely nothing..
so far for now, i really have no clue to progress further (as said didn´t test it on Win10 because of not messing around with the usb-driver there)..


If anyone here has a solution for this „white noise“-problem, please leave a comment here !!

ES9038Pro: New ES9038Pro out !! HIFIME UDA38PRO DAC (ES9038PRO + SA9227) 219€

hi there !! 😉 ,
came by chance about this gem->HIFIME UDA38PRO DAC (ES9038PRO + SA9227) with an ES9038pro !!
just absolutely fresh out->yesterday or so->“HiFimeDIY:
07/02/2018, 07:06:32 AM
Hi everyone, it’s now available to order! https://hifimediy.com/uda38pro-usb-dac-es9038pro Some more data will be added to the description soon. We do have a few units available now, and more after Chinese New Year. And we managed to get the price down to 219€„..

 

https://hifimediy.com/uda38pro-usb-dac-es9038pro
„The Hifime UDA38Pro utilises the ESS Sabre ES9038Pro DAC chip that has received a lot of attention and praised as the most important new DAC chip in ages…We have paired the ES9038Pro with OPA1622 output stage amplifier that can drive a wide range of loads including low and high impedance headphones and also line level loads like preamps and amplifiers… it can achieve up to 140dB !! dynamic range, -122 dB (0.00008%) total harmonic distortion plus noise (THD+N) in mono mode

Specs: (to come..)

ES9038Q2M: „Project 2“->building a BT-controlled HW-Volume-control (digital pot 10kOhm) MCP4131

so, 😉
because its a little bit silent around here lately, we still don´t know if the „Blue“ ES9038Q2M has a „shitty“ pcb and the „green“-ones sounds better, i have still buffer/“lock“-problems in windows using the V4.36 Singxer-driver on the Skysong-XMOS-USB in sample rates above 16/44 i wanted to use the onboard-HW-volume control, to which u can connect a normal 10kOhm-potentiometer (see pictures) easy..

 


i tested it here, and it works far not so good as expected and i guess u have a very small range of about 20% or so (in my feel) too..
i thought i could easy use the Arduino with analogwrite () and connect one pin to the middle of the onboard-3 pin but what i´ve read so far is that the Arduino can only send out PWM-signals so u need an external digital potentiometer (thats what i´ve read so far, don´t know if its true) and control it via the (in this case) SPI-bus/protocol..
for this u can buy a cheap MCP, in this case a MCP4131 of around 0,89€ and a Dip-8 socket (0,51€) etc.,etc..(more to come..)


(very good tutorial for this right now:
http://www.learningaboutelectronics.com/Articles/MCP4131-digital-potentiometer-circuit.php)

i will post here any „improvements“ (and (maybe) a full tut) asap..!! 😉

Topping NX4DSD->Thesycon XMOS-USB Driver Skysong/Singxer ES9038Q2M

so, 😉
because i have here really heavy problems in playing anything above 44,1/16bit due to buffer(and/or driver)-problems (on a raspberry the ES9038Q2M works perfectly) on a Skysong (Singxer)-USB-bridge and a ES9038Q2M („Blue“) i came by chance across this Topping NX4DSD..

it has also a XMOS-XU-208 and a ES9038Q2M „onboard“; interesting is the specification:
„16/32bit 44,1-768khz + DSD512 (native)“ and (whats more interesting):
NX4 DSD use costum driver from Thesycon“..
so, and thats the thing here..the „normal“ Singxer USB-Audio Driver 4.36″ does not work here satisfying with a ES9038Q2M..
2 possibilities: we get in future an update for also playing on this ES9038Q2M without problems from Singxer or we can get some custom made Theyscon driver which matches „our“ Skysong-Bridge+the ES9038Q2M..(any help here is really appreciated !!)
i´ve anyway attached here (and in the forum) the original Topping NX4DSD driver+manuals, which were btw. very interesting in setting up JRiver for perfect bitstreaming..(u have to use completely the ASIO-driver/interface..))
the Topping NX4DSD driver/manuals is the version V4.14..->NX4 DSD Manual and Driver V4.14->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=22
