Demorc Controller (Zephyr RTOS)

This repository contains the Zephyr-based firmware scaffold for the Demorc controller platform.
Current implementation focuses on project structure, board bring-up, module boundaries, and IPC foundations.

Current Scope

• Zephyr application under app/
• Board overlays for:
  • xiao_esp32c3
  • nucleo_l432kc
• Baseline modules:
  • state machine
  • CAN controller/protocol
  • LED controller
  • display controller
  • NFC auth
  • diagnostics
• zbus channels for inter-module communication
• UART logging + shell + periodic thread analyzer diagnostics

Repository Layout

• app/CMakeLists.txt, app/prj.conf: Zephyr build/config entrypoints
• app/src/: application and module source files
• app/include/: shared interfaces and types
• app/boards/: board-specific overlays
• docs/: supporting documentation

Build (Docker Zephyr Environment)

Build for XIAO ESP32-C3:

west build -s app -b xiao_esp32c3 -p always

Build for Nucleo L432KC:

west build -s app -b nucleo_l432kc -p always

Optional build-version override (if Zephyr warns about non-git ZEPHYR_BASE):

west build -s app -b xiao_esp32c3 -p always -- -DBUILD_VERSION=0.1.0

Hardware Notes

• SN65HVD230 transceiver board is currently treated as always-on in overlays.
