EspressifSystems/ESP8266_RTOS_SDK

EmbeddedBoard Support PackageActiveBilingual CN-EN

Provides an RTOS-based SDK for the ESP8266 microcontroller with FreeRTOS, lwIP, and Wi-Fi drivers integrated. Addresses the need for a complete development environment to build networked embedded applications on the ESP8266 without relying solely on the non-OS SDK.

C-based SDK built on FreeRTOS kernel with integrated lwIP TCP/IP stack, mbedTLS for TLS/SSL, and proprietary Wi-Fi libraries (libmain). Compilation uses the Xtensa LX106 GCC toolchain (v8.4.0 or v4.8.5 depending on SDK version). Supports menuconfig-driven build configuration. Core components include SPIFFS filesystem, cJSON, libcoap, and noPoll WebSocket library. Targets the single-core Xtensa-based ESP8266 SoC.

How it works

4-step pipeline, incremental by design — every run is dated.

1 · Collection

For each monitored organization, list_all_repos_by_owner with exponential retry on intermediate pages. Gitee token: 4500 req/h.

2 · Scoring

Multilingual semantic embeddings vs 4 domain definitions + anti-noise admission (curated keywords anchor, contrastive anti-domains). Hard filters upstream (third_party_*, mirrors/*, stale >2y).

3 · Enrichment

For each selected repo: Claude Haiku 4.5 produces Problem solved, How it works, Chinese specificity, Western equivalent. Bootstrap: no call if fiche already on disk.

4 · Incremental diff

state.json stores pushed_at per repo. Diff NEW / MODIFIED / UNCHANGED / DELETED per run, written to output/diff_YYYYMMDD.md.

Corpus 105 fiches × EN + FR

Tests 110 pytest, GitHub Actions CI

Bootstrap cost ~$1 (105 bilingual pairs × Haiku 4.5)

Incremental run cost ~$0.10-$0.50
