BP10 DSP Controller v0.5.2

BP10 DSP Controller v0.5.2

Build: commit e4ecfd90

Most users should use the 4 MB product build.

The 16 MB files are an ESP32-S3 Devboard Build intended for the
experimental 16 MB flash / 8 MB Octal PSRAM development board. They
are not generic board firmware.

Changes

• UI: rename Music Delay to Delay and Music Phase to Phase in the
  module summaries so the path-agnostic Generic ACP labels match the
  existing Pre EQ and Out EQ naming.
• UI: highlight the active Music or Rec path button in the same accent
  colour used by primary actions, by adding a .btn-secondary.active
  style next to the existing .btn-secondary rule.

Release 0.5.1 – DRC mode unlock, consistent Load Factory Values

0.5.1 - 2026-07-25

• Remove profile-dependent DRC mode lock on AIYIMA A800X: all modes 0-6
  (Full Band, 2 Band, 2 Band + Full Band) are now selectable through the
  same shared DRC view, matching the Generic ACP profile behaviour.
• Expand the A800X DRC view codec so that non-zero modes expose the correct
  lower, upper, full band visibility, crossover, and Q controls.
• Keep the A800X DRC wire protocol (54-byte four-path format) unchanged;
  all mode writes, readbacks, persist, import, and export operate through
  the existing full-frame codec.
• Make the DRC Load Factory Values button active in every mode. Clicking it
  resets the local form to mode 0 Full Band with the known A800X factory
  values without writing to the DSP until Apply.
• UI label: PreEQ → Pre EQ for consistency with Out EQ.

BP10 DSP Controller 0.5.0

Highlights

• Separate Generic Music and Rec DSP paths with path-aware persistence
• PreEQ and Out EQ readback baselines and local preview state
• USB Out Gain support
• Shared mode-aware DRC frontend and schema-driven codecs
• Multi-path configuration import, export, verify, and save
• Preserved AIYIMA A800X single-path compatibility

Images

• OTA update: bp10-dsp-controller-v0.5.0-ota.bin
• Full serial flash: bp10-dsp-controller-v0.5.0-full.bin
• Verify downloads with SHA256SUMS.txt.

Validated with host tests and hardware smoke tests on Generic ACP and AIYIMA A800X.

v0.4.6 – Delay readback fix, host tests, updated README

Changes

• Delay readback fix: Only verify delay/hq params when delay is enabled; DSP may normalize/zero params when OFF
• Profile persistence: Preserve user-requested delay params even when OFF
• Host tests: Added delay_verify_host_tests covering ON/OFF state and param matching
• README: Comprehensive update with building instructions, Wi-Fi setup, supported devices, and safety notes
