John Park’s CircuitPython Parsec: I2C Target

Executive Summary

You can turn a microcontroller into an I2C target for a second microcontroller. What is this witchcraft? Try out the code example To learn about CircuitPython: https://circuitpython.org

Open Silicon & Gate-Level Hardware Inspection

From a silicon and hardware engineering viewpoint: - **Interface Neutrality:** Mitigates dependency on proprietary BSPs, empowering open toolchains to address hardware directly. - **Supply Chain Verification:** Schematics and open pinouts allow deterministic audits against silicon errata. - **Lifecycle Decoupling:** Decouples physical hardware utility from commercial vendor end-of-life obsolescence.

Impact on the Open Ecosystem

Ensures that computational autonomy remains in the hands of the architect rather than closed silicon vendors.
