Some correction, it should be:
DSD64 at 2.8MHz and DSD128 at 5.6MHz.

yes, for the second time I wrong the text in the post but the firmware is ok

someone can make a test on Linux with DSD256 and DSD512 ?

Has anyone contacted amanero recently to buy their board? I sent an email 2 weeks ago for this groupbuy discount and no answer.

Will do once I get my DAC. Planning to use mpd and I think there is an option to switch between 176.4 and 352.8 for DoP.

Are you using ASIO to test new firmware ?

Yes, I'm using Amanero ASIO as I think it unleashed the full potential of Amanero and it works nicely with my DAW. Can't test the firmware though as I do not have PIC programmer ATM but I found that PIC18F4550 with in-built USB looks interesting.

Here the new firmware, final test still to complete

1) ok, solved
2) ok
3) ok, solved, now the volume range is 0Db to -127Db
4) ????
5) ok
6) ok
7) no, depend by remote when it repeat command
8) ok, solved
9) I am thinking about
10) ok, if you press the mute button durinfg the startup phase
11) no, No enought buttons to use in setting menu
12) no, It need an HW change
13) I can create a firmware with standby function but in this case is necessary a separated transf. for the controller, I can develop a different version if necessary
14) no, It is very complex
15) no, Not possible with ES9018 DAC remap
16) ok
17) ok, for DSD tracks display DSD32 at 2.8MHz and DSD64 at 5.6MHz
(probably Linux can support other types, 256 and 512, not tested)

-------------------------------------

1) Cannot save the volume level at 100%
2) Feature proposal : Save the input selection (other than USB).
3) Bug : Do not mute on high efficiency loudspeakers system when level at 1% (for example, remains very loud on VOTT).
4) Feature proposal : Insert a white-on-blue bargraph on the display for the level (while inverting the displayed characters on the same line to blue-on-white), very usefull with the remote.
5) Hide the blinking cursor
6) Display "192kHz" (now "191kHz")
7) Bug: Under certain circumstances pressing a button does not get handled. When pressing another button the last one gets executed (like pressing Vol- and then pressing Vol+, Vol- is actually performed)
8) Bug: While in settings mode if the input sample rate changes the display gets overridden with the changed sample rate (which shouldn't show in settings mode) while still being in settings mode
9) Personal feature proposal: Something I would like to have but nothing to complain about: auto dim/turn off the display after a timeout - reactivate it when the remote control is operated (and ignoring the first button that was pushed to turn it back on)
10) Feature: A way to display the installed firmware version
11) Personal feature proposal: The mute button should always be mute. No reuse of this button in any other display mode. It is kind of an emergency button and it should not matter what display mode you are currently in.
12) Feature proposal : Add a led on the front panel which blink when pressing on a button on the remote. Maybe that pins are already available for this on the controller pcb.
13) Feature proposal: standby and trigger out options (Quanghao is working on this)
14) Feature proposal: allow microprocessor to accept commands via amanero i2c interface - this should allow control of the DAC via a PC source and through this, android app.
15) Make Phase +/- work when playing via the USB input.
16) Save the Soft/fast roll off and Cut off frequencies the same way at the input save(preset) and Volume preset.

Hi Andrea,

About the new firmware, I wish that LCD display should be compatible with VFD.
I've already changed from LCD to VFD(Samsung 16T202DA1E) via pin to pin connection
But It is not working properly, I'm expecting a supporting feature from you

An externally hosted image should be here but it was not working when we last tested it.

Hi Andrea,

Could you edit this also:
- Change the start-up screen texts from "HQ-DAC Reference" to "HQ-Reference DAC", to tally with the frontplate name.

Comments to Firmware Ver51a

Bugs 1) to 17) seams to work OK:
I have added a few bugs more.

18) Display text: "Db" should be "dB"
19) Display board: Switch S- switches: USB link-->Optical-->AES/EBU, Switch S+ switches: AES/EBU-->Optical-->USB link (coax is missing)
20) Correct Display text "HQ-DAC Reference" to same Text on front plate shows "HQ-Reference DAC"
21) If playing USB then the format eg shows "DSD64". This text is not cleared when switching to SPDIF inputs(optical, Coax or AES/EBU) when SPDIF has "NO input".

Best Regards

Which IV is the "Ministry IV" does anybody know ?

Caad , have you a sample of the DXD PCM352, file ?

--> PCM382KHz corrected to PCM352KHz

Hi Andrea..

I Have checked 18) to 22) .. Looking good!!

All sample rates exept DSD256 and DSD512 has been checked and Display shows correct sample rates..

UPS..

One more bug just showed up..
23) When selecting input eg --> to USB. Then try to press one more time on either remote or S+ and suddenly the sample rate disapears.

What you press ?

Sorry, this is more detailed..

Press S+ AES/EBU-->Coax-->Optical-->USB (Link Lock and sample rates shows) --> USB (Link, Lock but sample rates disapear)
If i then restart the music from the PC then the sample rate shows again.

It is the same issue when using the remote and pressing the doubble arrow down.

Good findings, caad.

I have ordered this cheap USB PIC programmer, $12.67+free shipping.

Picpro Mini USB Pic Programmer for Microchip Pics K150 | eBay

Just received my last piece of LME op amp and after rolling in the soundstage becomes much wider, with great transparency, details and tonal balance.

I have covered the USB connector's pin 1 (Vcc pin) with a tape and powered the Amanero with DAC power, it works, no removal of LDO is needed.
