Summary

This PR updates the project documentation and the formal technical report to establish a clear distinction between the current v1.0 Prototype (Perfboard/Discrete) and the proposed v2.0 Silicon Revision (Integrated PCBA).

Changes

📄 Engineering Report (docs/)

  • Section 7.3 Revised: Updated the "Future Work" section of the LaTeX report. It now formally proposes the "Silicon Revision" architecture, replacing the previous "Phase II" text.
  • Key Specifications Added:
    • Migration to 4-layer SMD PCB for noise reduction ($< -80\text{dB}$).
    • Integration of external I2S Codecs (ADC/DAC) to bypass RP2040 internal converters.
    • Implementation of a Programmable Gain Amplifier (PGA) and relay-based coupling.

📚 Repository Documentation (README.md, oscilloscope-rp2040/)

  • Status Indicators: Added badges and warning blocks to the root README to clearly label the current codebase as a "Proof of Concept".
  • Roadmap Section: Added a detailed roadmap for v2.0, outlining the shift toward automated transfer function analysis.
  • Cross-Linking: Updated the subsystem documentation to point users toward the new master roadmap.

Impact

These changes align the documentation with the new strategic direction of the project, moving away from "hobbyist tool" messaging toward "precision instrumentation."

- Revised Section 7.3 (Future Work) to explicitly outline the 'Silicon Revision' (v2.0) architecture.
- Replaced the interim 'Phase II' (Laptop-as-Generator) proposal with the full hardware specification.
- Detailed the proposed transition to a 4-layer SMD PCB, external I2S ADC/DAC integration, and programmable AFE.
- Recompiled PDF artifact to reflect these changes.
- Root README: Added 'v1.0 Prototype' badge and blockquote to clarify the project's current proof-of-concept status.
- Root README: Added comprehensive 'Future Roadmap: Silicon Revision (v2.0)' section detailing the planned move to a custom PCBA.
- Oscilloscope README: Added 'Future Development' footer to link specific subsystem documentation back to the master roadmap.
