# DigiRadio Firmware
|
||
|
||
Open-source Hi-Fi DAB+/FM receiver firmware for the ESP32-S3.
|
||
|
||
**Status:** fw **0.8.2** — tabbed Web UI (now-playing, 6-band EQ, all APIs);
|
||
`IntegrationService`; **13** host tests; CI on `main`.
|
||
See [`docs/TODO.md`](docs/TODO.md) for the agent task list.
|
||
|
||
## Quick start
|
||
|
||
Open this directory (`Software/`) as the Cursor project so `AGENTS.md` and
|
||
`.cursor/rules/` load automatically.
|
||
|
||
```bash
|
||
idf.py set-target esp32s3
|
||
idf.py build
|
||
idf.py -p <port> flash monitor
|
||
```
|
||
|
||
Host unit tests (pure core, no hardware):
|
||
|
||
```bash
|
||
cmake -S components/core/test -B build-host \
|
||
-DCMAKE_CXX_COMPILER="$(brew --prefix llvm)/bin/clang++"
|
||
cmake --build build-host
|
||
ctest --test-dir build-host --output-on-failure
|
||
```
|
||
|
||
Documentation gates (must exit 0 before merging; also enforced in CI):
|
||
|
||
```bash
|
||
doxygen Doxyfile
|
||
python3 tools/check-manual-sync.py
|
||
python3 tools/check_si4684_blobs.py
|
||
python3 tools/gzip-www.sh # after editing components/net/www/index.html
|
||
```
|
||
|
||
Manual PDF (design + HTTP API + class reference):
|
||
|
||
```bash
|
||
cd docs/manual && latexmk -lualatex manual.tex
|
||
```
|
||
|
||
