Default ArDAM Lite controlled DAM1941

Hi folks,

I -almost- finished my ArDAM Lite controlled DAM1941.
It's now in "breadboarded" state, but sooner or later I will make a case.

I attached my configuration's block diagram.

The ArDAM Lite PSUs is DiyInHK dual LT3042 (+transistor) versions (+5V, +3V3).

My OLED is 1.3" SH1106 chip version (I2C).

I rewrite Dimdim's code.

Because Arduino Nano has very narrow space for program, only the "necessary" commands and status informations have been implemented:

Commands:
- Volume up; Volume down;
- Source selection: Auto, USB, AES/EBU, BNC SPDIF, RCA SPDIF, Opical (Soren now not implemented I2S);
- Filter changing: four filter selection.

Status display:
- Volume;
- Type of stream (PCM, DSD);
- Sample rate;
- Source;
- Filter.

Because Nano's space is "full", the "draw_logo" procedure now is commented.

The IR codes is my remote control's code, must be change your remote codes.
Use attached Dimdim's "IR_Scanner" for detecting codes from your IR remote control.

If you want to see DAM's serial commands, use attached "serial_console" program.

Have fun and enjoy yourself!

Each component purchasable from the net, ArDAM Lite PCB there from Dimdim, 1.3" OLED, Arduino Nano, parts from ebay.

I use this PSU -because I own several pieces- for control and display:
DiyInHK dual PSU from 0.8uV Ultralow noise DAC power supply regulator 3.3/5/7V 1.5A*x2 - DIYINHK.

My breadboarded system use LT3045 PSUs for DAM, but any good PSU (for example UBiB) usable.

I bought two bobbin transformers for PSUs (INDEL 40VA 7.5V or 9V AC, depends of PSU type). Any transformer usable which have low primary-secondary capacitance. For me toroid not this type.
