Just to be clear, I have not yet listened to my BuffIIIPro builds. I was saying my DAM 1021 setups are currently my best. I suspect based on comments from others that will change once I get my BuffIIIPro setups running.

AND of course, implementation is everything. I have some additional mods planned to my DAM 1021 setups to give them the best chance of competing... and am pulling no punches on my BuffIIIPro builds for the same reasons.

Hi again Dimitris,

Which are the essential differences between ArDAM1021 and ArDAM1021 Lite? I know display and memory usage are different, but anything else feature wise?

Thank you

ArDAM Lite "as is" only supports control via IR versus the rotary encoder support of the non-lite version. Other than that, just the obvious (aesthetic) differences.

noted, thank you! i'm trying to decide on a system, most likely will invest on a DAM1021 + your ArDAM (non-lite) and maybe an isolator. Do you sell your boards or offer the design somehow?

I'm out of pcbs at the moment, but I do have the full Eagle files for my Isolator PCB up on my blog: Universal Signal Isolator shield for the Arduino DUE | Dimdim's Blog

It's not hard to generate gerbers and order pcbs.

But I'm also considering starting a GB thread to see if there is interest.

Hi Dear Dimitris;
Diyinhk ES9028 pro has gpio1 (40) Mute pin, i connect this pin led for listen some data(led on/off) but ı dont see anythings.
i listening native dsd with volumio, when i want forward music coming crankling sound, i want to make mute but i dont see anything gpio1 (40.pin)
How can activate gpio1 mute on your software?
My old es9018 mute out (40.pin) working so good, I need to activate my es9028pro automute register..
Your software is so silence when i forward dsd64 to dsd128, but when i forward same sample rate (dsd64 to dsd64) hearing crankling sound so high...
BR
Sercan...

Hi there Sercan,

Enabling automute on the 9028/38 is relatively easy to do. I've implemented it in the current version of my code, which I've not yet made public (since it includes a lot more functionality that has not been properly tested yet).

Let's see if this will work in your version of the code.

Change this:

Code:
ChangeBit(dac, 0x00, 0, 1);                   // Put DAC in RESET mode
delay(500);                                   // Wait for 500ms
ChangeBit(dac, 0x00, 0, 0);                   // Take DAC out of RESET mode
mute = 1;                                     // Put DAC in mute
setMute();                                    // Put DAC in mute
ChangeBit(dac, 0x09, 7, 0);                   // Setup GPIO4
into this:

Code:
ChangeBit(dac, 0x00, 0, 1);                   // Put DAC in RESET mode
delay(500);                                   // Wait for 500ms
ChangeBit(dac, 0x00, 0, 0);                   // Take DAC out of RESET mode
mute = 1;                                     // Put DAC in mute
setMute();                                    // Put DAC in mute
ChangeBit(dac, 0x02, 7, 1);                   // Enable Automute
ChangeBit(dac, 0x02, 6, 1);                   // Enable Automute
WriteRegister(dac, 0x04, 255);                // Setup automute time to minimum (186ms for 44.1K FSR)
ChangeBit(dac, 0x09, 7, 0);                   // Setup GPIO4 for Automute / Lock Interrupt
This will not get your MUTE led to light (you need to add more code to do that), but if it works the way it should it will enable automute for you.

Hi Dear Dimitris;
I changed code like you say.
Your GPIO4 pin have 2 status ( Automute and Lock) now. This is problem for encoder and remote control. Because interrupt is HIGH, encoder and remote control can't work. How can i change GPIO4 pin info for only Lock status ?
I read ES9028PRO datasheet, and I changed again code like this :
Code:
  ChangeBit(dac, 0x02, 7, 1);                   // Enable Automute
  ChangeBit(dac, 0x02, 6, 1);                   // Enable Automute
  WriteRegister(dac, 0x04, 100);                // Setup automute time to minimum (186ms for 44.1K FSR)
  ChangeBit(dac, 0x08, 3, 0);                   // Setup GPIO1 for Automute
  ChangeBit(dac, 0x08, 2, 0);                   // Setup GPIO1
  ChangeBit(dac, 0x08, 1, 0);                   // Setup GPIO1
  ChangeBit(dac, 0x08, 0, 0);                   // Setup GPIO1

  ChangeBit(dac, 0x09, 7, 0);                   // Setup GPIO4 
  ChangeBit(dac, 0x09, 6, 0);                   // Setup GPIO4
  ChangeBit(dac, 0x09, 5, 0);                   // Setup GPIO4
  ChangeBit(dac, 0x09, 4, 1);                   // Setup GPIO4 for Lock Interrupt
Now mute led is working. But still GPIO4 interruptPin always be HIGH. Can you help me for that ?
