- boards/**/zephcore.yml: one manifest per board/preset (release roles,
variants, catalog metadata, capabilities); scripts/board_manifest.py
validates and serves them to build.sh, gen_provider_catalog.py and
docs/supported_boards.md
- cmake/zephcore_board.cmake: board dir -> platform, shared by app and
sysbuild; removes the board-name regex lists and 7 separate globs
- conf chain: exact-name role/debug classification checked against
Kconfig, idempotent across non-pristine reconfigures, version string
single-sourced (BT DIS rev generated), day-granular build epoch
- Doom easter egg: Kconfig default for the wio_tracker_l1 companion
instead of a build.sh-only flag
- catalog: maker for the LR2021 EVK (KeyError before); CI installs PyYAML
- user -DEXTRA_DTC_OVERLAY_FILE overlays now take precedence over derived overlays
Verified: identical .config, DTS and source lists for 97 board/role
configs; identical images for 4 reference builds; identical build.sh
command/artifact set and catalog content.
Add a board-aware battery SOC system replacing the two independent
linear approximations that existed in the UI helpers.
New helpers/battery_curve.{h,c}: a 21-point (5% step) OCV lookup table
with integer linear interpolation. The default generic LiPo curve is a
weak symbol — any board can override it by dropping a battery_curve.c
into its board directory. CMakeLists.txt selects the board-specific file
when present, falling back to the generic.
Board.h gains getBattPercent() (default 0); ZephyrBoard implements it
via battery_curve_lookup().
Board-specific curves added for boards with measured cell data:
t1000_e, rak_wismesh_tag, thinknode_m6, sensecap_solar, wio_tracker_l1.
ADC multiplier corrections applied across all nRF52840 boards:
- Boards using a correctly-derived 3600×ratio formula get +0.5% to
compensate for nRF SAADC gain error (7200→7236, 6300→6332, etc.)
- rak_wismesh_tag, rak3401_1watt, gat562_30s had multipliers copied
from Arduino's 3.0V AREF formula; corrected to 3600×1.73×1.005=6259
- xiao_nrf52840 (10911) left unchanged — empirically calibrated value
above the theoretical, assumed already correct for that hardware
get adc.multiplier now reports current mV reading and the board's
curve 100% target, making field calibration self-guiding.
- only two leds, red and blue
- fix pin definition and polarity for leds
- remove unmapped pins
- swap buttons, so they match datasheet and marking on buttons
- flood retransmit jitter now capped at min(2000ms, 6·airtime) instead of
fixed 2000ms — spreads tighter at SF7, unchanged at SF8
- reactive per-dupe backoff cap now min(2000ms, 12·airtime), keeps
semantic of "push past ~12 relay slots"
- contention ring 16 → 24 for 50-neighbor hilltops
- companions passively track heard floods (warms EMA without forwarding)
and spread their own TX by up to min(1000ms, 3·airtime), hopefully
fixing repeaters missing companion's first transmission
config cleanup:
- move BLE TX buffer bumps (ACL_TX=12 etc.) from zephcore_common.conf to
esp32_common.conf — the Espressif blob needs them, nRF doesn't, and
the bumps were overflowing nRF52840 RAM
- remove CONFIG_ZEPHCORE_MAX_CONTACTS=510 overrides from 5 nRF52840
companion boards; Kconfig default of 350 fits with comfortable margin
(wio prod: 91% → 79% RAM)
