Records raw demodulated CC1101 GDO0 output at 100 kHz into a 50 KB
bit-packed static buffer (up to 4 seconds). Replay drives GDO0 in
direct TX mode at the same sample rate, looping until stopped.
- config.h: CAP_SAMPLE_HZ / CAP_DURATION_S / CAP_BUF_BYTES defines
- main.cpp: capRecordISR / capReplayISR using hw_timer_t on timer 3
- main.cpp: startCapture / startReplay / stopCapture management functions
- main.cpp: capAnalyze() estimates bitrate and duty cycle from transitions
- main.cpp: five HTTP endpoints under /api/capture/*
- main.cpp: loop() state machine auto-finalises buffer-full capture
- kHtml: Capture / Replay card with freq input, radio selector,
REC/STOP/REPLAY buttons, progress bar, stats grid, waveform canvas
