Streaming (main feature this session): - New WebRadioConfig/WebRadioJson core types, ISecureStore-backed persistence - New webradio::WebRadioService (thread-safe live config) + GET/POST /api/streaming - web_radio_stream task now runtime-toggleable (no reboot), no hardcoded URL - Content-Type diagnostic: warns clearly when a URL is a webpage, not an audio stream Boot cleanup: - Removed boot-time auto FM/DAB tune, auto-beep, and the (now-concluded) Si4684 crystal IBIAS/CTUN empirical sweep from main.cpp — tuning/beep are on-demand via the existing REST API only Web UI: - Modernized styling (cards, gradients, toggle switches, light/dark theme) - New Stream tab wired to /api/streaming Fixes found via real idf.py build (not just clangd): - Restored wrongly-removed si4684/Si4684Tuner.hpp include in main.cpp - Fixed MP3Decode() argument types in web_radio_stream.cpp (unsigned char**/int*) Quality-gate fixes: - Host-test stub headers (esp_log.h, freertos/*) so TunerService.cpp's scanForStation logging/pacing compiles for station_service_test / integration_service_test instead of running stale binaries - Added WifiScanner and WebRadioService manual sections; filled in missing Doxygen docs on BluetoothService, i2s_sdata_probe, test_firmware, Bt1035At - Ignore clangd's .cache/ index directory Also includes prior uncommitted work carried in the tree: Wi-Fi/Bluetooth device scan REST API and UI (WifiScanner, BT scan), SigmaStudio TCP bridge, and the current ADAU1701 SigmaStudio DSP program export.

Runtime (fw 0.8.3)
- Boot: ESP32 replays the active
DspProgramover I2C viaadau1701::Adau1701Driveron every power-up. Source order: valid blob in thedspflash partition, else the embedded export from this folder (EmbeddedDspProgramSource). - Program update:
POST /api/dsp/programwith aDRADv1 blob (seeSoftware/tools/pack_dsp_program.py). Device reboots and loads the new script on next boot. - Live control: six-band PEQ, input mixer, master volume, stereo/bass
enhancement overlays — safeload via
audio::AudioServiceand 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 inAdau1701ParamMap.hppif 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.
DRAD v1 blob (flash / HTTP upload)
Layout: magic DRAD, version u16 (=1), write count u16, CRC32 (IEEE over
writes section), then for each write: address u16, length u16, data bytes.
Pack from JSON with Software/tools/pack_dsp_program.py or use
core::serializeDspProgramBlob() in host tests.
