From 0a7527c92e5d11510e6bea89d71ac36810220c25 Mon Sep 17 00:00:00 2001 From: Jeff Hykin Date: Sun, 12 Apr 2026 18:22:17 -0700 Subject: [PATCH 01/23] feat(arduino): add ArduinoModule with virtual (QEMU) support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces a new DimOS module type for Arduino-based hardware with LCM- compatible binary serialization, a generic serial↔LCM bridge, and a QEMU-based virtual mode for testing sketches without real hardware. Core pieces: - lcm_coretypes_arduino.h: drop-in replacement for LCM's coretypes that compiles on AVR (no malloc, no variable-length, memcpy-safe float casts) - arduino_msgs/: C encode/decode for 20 fixed-size LCM types across std_msgs and geometry_msgs, wire-format identical to LCM C++ (minus the 8-byte fingerprint hash, which the bridge prepends/strips) - dsp_protocol.h: framed binary protocol [0xD1][topic][len][payload][crc8] with a direct USART driver (bypasses Arduino HardwareSerial to avoid its interrupt-driven TX, which doesn't fire in QEMU's AVR USART model) - arduino_bridge: generic C++ binary that maps topic_id <-> LCM channel via CLI args; one binary for all ArduinoModule instances - ArduinoModule: Python base class with build() RPC that generates dimos_arduino.h from stream declarations, compiles the sketch via arduino-cli, and builds the bridge. When virtual=True, start() launches qemu-system-avr with -serial pty and parses the PTY path from stderr. - flake.nix: builds arduino_bridge and provides arduino-cli + tools Tests: - test_wire_compat: C++ test that builds against the same dimos-lcm C++ headers as the bridge and verifies byte-level equivalence for all 20 message types + a roundtrip. 21/21 passing. - examples/arduino_twist_echo: end-to-end example with a Twist-echo sketch, a TestPublisher module, and a blueprint wiring them together. Verified: real DimOS coordinator + worker pool + LCM runs the sketch in QEMU and Twist flows round-trip through Python <-> bridge <-> DSP <-> virtual ATmega328P. --- dimos/core/arduino_module.py | 596

Running a blueprint from plain Python would fail with "arduino-cli not found" unless the user had already entered the flake shell — defeating the point of importing the module as a library. Package all three tools as a new ``dimos_arduino_tools`` flake output (a ``symlinkJoin`` over ``arduino-cli.pureGoPkg``, ``avrdude``, and ``pkgs.qemu``) and resolve it at runtime via ``nix build .#dimos_arduino_tools --print-out-paths --no-link``, cached per process. Only ``nix`` itself needs to be on PATH; the e2e test's skip-precheck is relaxed accordingly. Switch the dev shell from ``pkgs.arduino-cli`` (a bwrap FHS wrapper that fails when nested userns is restricted) to ``pkgs.arduino-cli.pureGoPkg`` (the unwrapped Go binary, which runs natively on any host with a real ``/lib64/ld-linux-x86-64.so.2`` or nix-ld enabled). Also fix a latent bug in ``_generate_header``: arduino-cli's sketch preprocessor doesn't honor ``-I`` paths passed via ``compiler.cpp.extra_flags``, so a header living outside the sketch dir was invisible during the preprocessing pass, breaking any sketch that referenced an enum from the generated header. Write ``dimos_arduino.h`` directly into the sketch dir (and gitignore it). --- dimos/core/arduino_module.py | 191 +++++++++++++----- dimos/core/tests/test_arduino_module.py | 77 ++++++- dimos/hardware/arduino/.gitignore | 9 +- .../arduino_twist_echo/test_e2e_virtual.py | 27 +-- dimos/hardware/arduino/flake.nix | 37 +++- 5 files changed, 264 insertions(+), 77 deletions(-) diff --git a/dimos/core/arduino_module.py b/dimos/core/arduino_module.py index a1521e3b54..51b25734fb 100644 --- a/dimos/core/arduino_module.py +++ b/dimos/core/arduino_module.py @@ -35,6 +35,7 @@ class MyArduinoBot(ArduinoModule): from dataclasses import dataclass import errno import fcntl +import functools import glob import inspect import json @@ -65,6 +66,86 @@ class MyArduinoBot(ArduinoModule): _BRIDGE_BUILD_LOCK_PATH = _ARDUINO_HW_DIR / ".bridge_build.lock" +@functools.lru_cache(maxsize=1) +def _arduino_tools_bin_dir() -> Path: + """Resolve the ``bin/`` directory of the ``dimos_arduino_tools`` flake output. + + The flake packages ``arduino-cli`` (unwrapped Go binary), ``avrdude``, + and ``qemu-system-avr`` into a single ``symlinkJoin``.

-0700 Subject: [PATCH 08/23] Add transport-agnostic LCM pubsub for Arduino with subscribe/callback API - New dimos_lcm_pubsub.h: transport-agnostic LCM pubsub engine (from dimos-lcm) - New dimos_lcm_serial.h: serial transport adapter wiring DSP + LCM pubsub - DSP protocol upgraded to 2-byte topic IDs (uint16_t, up to 65534 topics) - C++ bridge simplified: passthrough for fingerprinted payloads, 2-byte topics - ArduinoModule generates channel mapping table, type descriptors, channel constants - Example sketches use new API: dimos_subscribe() + dimos_handle() + typed callbacks - Arduino message headers updated with LCM fingerprint constants - Fixed flake.nix nixpkgs compatibility (pureGoPkg removed upstream) - All 23 unit tests pass, e2e virtual Arduino round-trip passes ---
