ADAU1701 SigmaStudio export

SigmaStudio project DigiRadio, IC1 = ADAU1701. Shipped with DigiRadio firmware 0.8.3.

Key files

File	Role
`DigiRadio_IC_1.h`	Program/param RAM data + `default_download_IC_1()`
`DigiRadio_IC_1_REG.h`	Control register map (safeload trigger)
`DigiRadio_IC_1_PARAM.h`	Parameter cell indices (`ADDR_*`)
`DigiRadio_NetList.xml`	Schematic netlist (reference)
`SigmaStudioFW.h`	Safeload / I2C glue API

Runtime (fw 0.8.3)

Boot: ESP32 replays default_download_IC_1() over I2C via adau1701::Adau1701Driver on every power-up.
Live control: six-band PEQ, input mixer, master volume, stereo/bass enhancement overlays — safeload via audio::AudioService and REST /api/audio/*; profile persisted in encrypted NVS.
Web UI: Audio tab — 6 EQ sliders + mixer/enhance controls.

I2C address: 7-bit 0x34 (ADDR0=ADDR1=GND). Sample rate: 48 kHz.

Safeload implementation: components/drivers/adau1701/src/SigmaStudioFW.c. Parameter map: components/drivers/adau1701/include/adau1701/Adau1701ParamMap.hpp.

After re-exporting from SigmaStudio

Action → Export System Files into this folder (overwrite headers).
Reconcile new ADDR_* symbols in Adau1701ParamMap.hpp if block names moved.
Rebuild and flash firmware (idf.py build).
Update manual: docs/manual/ch-sigmastudio.tex, docs/manual/ch-adau1701.tex.

Do not use SigmaStudio Link Compile Download on DigiRadio — export only; the ESP32 programs the DSP at every power-up.
