Doxygen:
- Doxyfile: minimal config, HTML output to docs/, no LaTeX
- @file/@brief on all source files, full @param/@return on public API
- docs/ added to .gitignore
clang-format (14, Linux brace style, 4-space, column 100):
- .clang-format added
- Applied to entire codebase; this commit is the canonical baseline
- just format rewrites in-place; just format-check is the CI gate
cppcheck (--enable=warning,style,performance,portability):
- Linker-symbol pointer comparisons in startup.c suppressed with
inline cppcheck-suppress (false positives, not real bugs)
- just lint runs cppcheck; zero warnings required to pass
Dockerfile gains clang-format, cppcheck, doxygen packages so all
tools run inside the existing container -- host stays clean.
Gitea Actions (.gitea/workflows/ci.yml):
- Four parallel jobs: build, format, lint, docs
- All jobs use the same Dockerfile-based image
- Doxygen job fails on any warning line in output
radio_init() configures RADIO in NRF_1Mbit proprietary mode: 8-bit
length field, 4-byte address (BASE0+PREFIX0), 2-byte CRC-16/CCITT,
0 dBm TX power, channel 20 (2420 MHz). READY->START and END->DISABLE
shortcuts let radio_tx() trigger the full ramp-up/TX/disable sequence
by writing TASKS_TXEN once, then polling EVENTS_END.
main.c sends a fixed 4-byte test frame on every button press.
FHSS and AES remain compiled but are not called.
New bitfield unions in regs.h: radio_pcnf0_t, radio_pcnf1_t,
radio_crccnf_t, radio_shorts_t.
