The mppt-testbench Python tooling had drifted from the flashed firmware
(bundled fw e7a23a3 vs live 1b85532) and could no longer communicate:
- stm32_link.py: CRC8 -> CRC-16/CCITT-FALSE; telemetry 68B -> 78B
(btemp, cmp_outer/inner, iout_slow, vfly_ofs_applied); add PTYPE_INT16
and commands 0x12-0x18; replace PARAMS with the current 37-param map
(single dt_normal, no dt brackets; test_corr/phase_ofs, phase PI,
precharge PI, duty dither; vfly_active 0-3).
- tuner.py: retire per-bracket deadtime; sweep the single dt_normal.
- cli.py: update tune-deadtime, help/examples, btemp readout;
default ports COM11 (load) / COM4 (stm32).
- debug console TUI: sync protocol.py/app.py/status_bar/telemetry_panel
from live (new command keys, link RX/TX/loss stats, single dead-time,
new telemetry fields, param-write auto-retry); add duty_fft.py.
- README: rewrite parameter table, deadtime section, ports, keybindings.
Verified: protocol round-trip self-tests + live `bench stm32-read`
reading all 37 params over COM4.
