GUI: live STM32 telemetry + sweep guards + auto-logging + bench-plot
- stm32_link.py: port to the live 114-byte broadcast protocol (magic 0xAA55AA55, odd parity 8-O-1, 100 Hz publish, repetition-validated, no CRC); 39 params incl. adc4_trig_phase/iin_zero_sum, CLEAR_FLAGS, 30-bit flag table; commands stay CRC-16 framed; Telemetry aliases BroadcastData, efficiency uses iout_slow and eff_net subtracts P_sys - gui_workers.py: STM32Worker reader thread with counter dedup, rate/ loss counters, 20 s graph history, full-rate telemetry CSV writer - gui.py: right-side telemetry panel (link state, power + EFF net, heatsink/board temps, Vfly group, control, HRTIM, status-flag checkboxes, fault registers), Vfly + selectable corr/phase-ofs graphs, 20 s rolling window on all plots, dual CSV logging (merged stm_* columns + <stem>_telem.csv), logging on by default into logs/data_<timestamp>.csv, Plot Eff button - sweep guards: PSU 20 A input-current gate (conservative estimate + measured backstop + I-limit clamp), thermal pause at 57/77 C holding the load at 1 A until cooled 5 C below threshold, CC range pinned to R2 for the whole run with empirical range-max readback rejection - plot_eff.py + bench-plot entry point: efficiency vs Vin vs current maps from any logged CSV (sweep / data log / telem autodetect), file dialog when launched without args - bench.py: HIOKI FAST response speed, 5 s settle defaults; cli.py stm32-read prints the full broadcast; README + .gitignore updates Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
