ChuMicro: open-source Python for CircuitPython and MicroPython boards

Projects

Everything published under this organization.

ChuMicro

Python libraries for microcontrollers that never freeze your program, plus the host tools that deploy them. One codebase runs on CircuitPython, MicroPython, and CPython.

Libraries

Run on the board. Install one on its own or take the bundle.

chumicro-timing Wraparound-safe millisecond tick helpers plus wait value objects (deadlines, rates, signals) for CircuitPython, MicroPython, and CPython.
chumicro-runner Tick-based task runner for CircuitPython, MicroPython, and CPython: non-blocking check/handle scheduling without async.
chumicro-wifi Unified wifi supervisor across CircuitPython, MicroPython, and CPython: sole-supervisor model with reconnect, state machine, and per-runtime adapters.
chumicro-requests Non-blocking HTTP/1.1 client for CircuitPython, MicroPython, and CPython.
chumicro-http_server Non-blocking HTTP/1.1 server for CircuitPython, MicroPython, and CPython.
chumicro-mqtt Non-blocking MQTT 3.1.1 client (QoS 0+1) for CircuitPython, MicroPython, and CPython.
chumicro-websockets Non-blocking WebSocket (RFC 6455) client and server for CircuitPython, MicroPython, and CPython.
chumicro-sockets Cross-runtime TCP, TLS, and UDP sockets for CircuitPython, MicroPython, and CPython
chumicro-ntp Runner-shaped SNTP client over an injected UDP socket: pure Python, cross-runtime.
chumicro-config Standardized runtime-config helpers for ChuMicro libraries: section loader plus on-device runtime-config reader.
chumicro-kvstore Tiny mutable key-value store for persisted runtime state (counters, timestamps, tokens) across CircuitPython, MicroPython, and CPython.
chumicro-msgpack Compact MessagePack serialization for CircuitPython, MicroPython, and CPython: delegates to the native C module when available.
chumicro-compat Cross-runtime compatibility polyfills for CircuitPython, MicroPython, and CPython: functools.partial and more.

Host tools

Run on your computer: deploy code, watch a board, flash firmware.

chumicro-workspace Host-side runtime for ChuMicro project workspaces: config merge, secrets resolution, deploy orchestration, command dispatch.
chumicro-deploy Host-side device transports and deploy tooling for CircuitPython and MicroPython boards.
chumicro-repl Host-side serial REPL for CircuitPython and MicroPython boards with traceback highlighting.
