BruceButBetter v1.2.0 — Self-Test SPI, Si5351 favorites, CI release automation

Downstream fork of pr3y/Bruce for the DIY ESP32-S3 N16R8 build.

New in 1.2.0

• Self-Test now probes SPI too — alongside the I²C scan it reports microSD and both NRF24 radios ([OK]/[--]). Probes first, draws once (no shared-SPI screen glitch). CC1101 stays in the RF menu; NRF24 BruceDevices#2 gated on NRF24_2_CE_PIN.
• Si5351 frequency favorites — RF Gen → Favorites: save/recall CLK0 frequencies, persisted to /si5351_fav.txt on LittleFS (survives reboot).
• Tag-triggered CI release — release.yml builds the whole board matrix on a v* tag and auto-attaches each merged Bruce-<env>.bin here.

Flash

• Browser (recommended): https://yoursel71.github.io/BruceButBetter/ — pick version + board, connect the left USB-C.
• esptool (merged image at 0x0): esptool.py --chip <esp32|esp32s3> -p COMx write_flash 0x0 Bruce-<board>.bin

Self-Test SPI is in every board; Si5351 favorites/calibration are ESP-General (Si5351-equipped) builds. Bins attach automatically once the matrix finishes (~15 min). esp32-c5 / nesso-n1 build from source.

BruceButBetter v1.1.0 — Self-Test, Si5351 calibration, dual-NRF24

BruceButBetter v1.1.0 — three new firmware features over upstream Bruce, plus a multi-board browser flasher.

New in 1.1.0

• Hardware Self-Test — a new top-level menu that scans the I²C bus and reports every module that
  answers ([OK] 0xNN with OLED / PN532 / Si5351 / RTC / sensor labels). Plug in, run it, confirm
  your wiring in seconds — built for the DIY audience.
• Si5351 live calibration — RF Gen → Calibrate: outputs a 10 MHz reference on CLK0 and lets you
  trim the crystal correction (ppb, variable step) live to zero-beat against a known source.
• Dual-NRF24 spectrum — when a second NRF24 is populated, the 2.4 GHz analyzer scans odd channels
  on radio 2 in parallel with radio 1's even channels (~2× faster sweep, 2x badge). Single-radio
  boards are unaffected (automatic fallback). Parallel-RF path is hardware-untested — validate on a
  real dual-radio build.
• Multi-board web flasher — the browser flasher now
  flashes any of 45 boards (chip family auto-matched); no toolchain.

esptool (merged image at 0x0):

esptool.py --chip <esp32|esp32s3> --port COMx write_flash 0x0 Bruce-<board>.bin

This release ships refreshed .bin images for the key boards (ESP-General N16R8 + popular
targets). The Si5351 calibration and dual-NRF24 features are specific to the ESP-General build;
Hardware Self-Test is in every board. The full 45-board set from v1.0.0 still applies for boards
not re-listed here.

Notes

• Classic-ESP32 boards (Marauder, most CYD, ESP-General-devkit) ship the injection-patched net80211 — raw 802.11 TX (deauth / beacon spam) works.
• arduino-nesso-n1 and the esp32-c5 variants are not in this set (Windows build-env / riscv-toolchain limitations) — build from source on Linux if needed.
