FreeRTOS？ FreeRTOS 是與全球領先晶片公司合作開發的 15 年期間，現在每 170 秒下載一次，是市場領先的微控制器 和小型微處理器即時作業系統 (RTOS)。FreeRTOS 在 MIT 開放原始碼授權下自由發佈，包含一個核心和一 組不斷增長的程式庫，適合所有產業領域使用。FreeRTOS 的構建重點是可靠性和易用性。 FreeRTOS 包含用於連線、安全性和 over-the-air (OTA) 更新的程式庫。FreeRTOS 也包含示範應用程式， 可在合格的主機板上顯示 FreeRTOS 功能。 FreeRTOS 是開放原始碼專案。您可以在 https://github.com/FreeRTOS/FreeRTOS 上下載源代碼，進行更 改或增強功能，或在 GitHub 網站上報告問題。 我們根據 MIT 開放原始碼授權發行 FreeRTOS 程式碼，因此您可以在商業和個人專案中使用它。 我們也歡迎您對 FreeRTOS 文件的貢獻 (FreeRTOS 使用者指南、FreeRTOS 移植指南和 FreeRTOS 資格 指南)。若要檢視文件的降價來源，請參閱 https://github.com/awsdocs/aws-freertos-docs。它是根據創用 CC（CC BY-ND）許可證發布的。 正在下載 FreeRTOS 原始程式碼 從 freer tos.org 的下載頁面下載最新的 Free RTOS 和長期 Support (LTS) 套件。 FreeRTOS 版本控制 單個庫使用 x.y.z 樣式的版本號，類似於語義版本。x 是主要版本號，y 是次要版本號，從 2022 開始，z 是 補丁號。在 2022 年之前，z 是一個點發布號，這需要第一個 LTS 庫具有形式 「x.y.z LTS 補丁 2」的補 丁號。 圖書館套件使用 yyyymm.x 樣式的日期戳版本號。yyyy 是年份，mm 是月份，x 是顯示月份內發行順序的可 選序號。就 LTS 套件而言，x 是該 LTS 發行版本的連續修補程式編號。套件中包含的個別程式庫是該程式庫 在該日期的最新版本。對於 LTS 軟件包，它是最初作為 LTS 版本在該日期發布的 LTS 庫的最新補丁版本。 FreeRTOS 長期 Support FreeRTOS 長期 Support (LTS) 發行版本會在發行後至少兩年內收到安全性和重要錯誤修正 (應該是必要 的)。透過這項持續的維護，您可以在整個開發和部署週期中整合錯誤修正，而不會因為更新到 FreeRTOS 程式庫的新主要版本而造成昂貴的中斷。 使用 FreeRTOS LTS，您可以獲得構建安全連接 IoT 和嵌入式產品所需的完整庫集。LTS 有助於降低與更新 已在生產中的設備上的庫相關的維護和測試成本。 FreeRTOS LTS 包括 FreeRTOS 核心和 IoT 程式庫：自由傳輸 + TCP、核心 QTT、核心 HTTP、CorekCS11、Corejson、AWS IoT OTAAWS IoT Device Defender、AWS IoT工作和AWS IoT Device Shadow。如需詳細資訊，請參閱 FreeRTOS LTS 程式庫。 FreeRTOS 維護計劃 AWS此外還提供 FreeRTOS 延伸維護計畫 (EMP)，可在您選擇的 FreeRTOS 長期 Support (LTS) 版本上提 供安全性修補程式和重大錯誤修正，最長可延長 10 年。使用 FreeRTOS EMP，您以 FreeRTOS 為基礎的長 1 FreeRTOS 使用者指南 FreeRTOS 架構 壽裝置可以仰賴具有功能穩定性並接收多年安全性更新的版本。您會及時收到 FreeRTOS 程式庫上即將進行 修補程式的通知，因此您可以規劃在物聯網 (IoT) 裝置上部署安全性修補程式。 若要進一步了解 FreeRTOS EMP，請參閱功能頁面。若要開始使用，請參閱開始使用 FreeRTOS 延伸維護 計劃 (EMP) (p. 13) FreeRTOS 架構 FreeRTOS 包含兩種類型的存放庫，單一程式庫存放庫和套件存放庫。每個庫存儲庫都包含一個庫的源代 碼，沒有任何構建項目或示例。Package 儲存庫包含多個程式庫，並且可以包含展示程式庫使用情況的預先 設定專案。 雖然套件儲存庫包含多個程式庫，但它們不包含這些程式庫的複本。相反，包存儲庫將它們包含的庫引用為 git 子模塊。使用子模塊可確保每個單獨的庫都有一個真實來源。 個別程式庫 git 儲存庫會在兩個 GitHub 組織之間分割。包含 FreeRTOS 特定程式庫 (例如 FreeRTOS 的 +TCP) 或一般程式庫 (例如 CoremQTT，這是雲端不可知的，因為它適用於任何 MQTT 代理程式) 的儲存庫 位於 FreeRTOS GitHub 組織中。包含AWS IoT特定程式庫 (例如AWS IoT over-the-air 更新用戶端) 的儲存 庫位於AWS GitHub組織中。下圖說明了結構。 符合免費使用者資格的硬體平台 下列硬體平台符合 FreeRTOS 的資格： • ATECC608A 零接觸佈建套件，適用於AWS IoT • Cypress CYW943907AEVAL1F 開發套件 • Cypress CYW954907AEVAL1F 開發套件 • 柏木 CY8CKIT-064S0S2-4343W 套裝 • 濃縮咖啡 ESP32-DevKit C 型 • Espressif ESP-WROVER-KIT • 義式濃縮咖啡 ESP-WROOM-32SE •
