下載 FreeRTOS 和 OTA 示範程式碼
建置示範應用程式

  1. 請遵循 中的指示，將aws_demos專案FreeRTOS 入門匯入 Code Composer Studio、設定您的 AWS IoT 端點、Wi-Fi SSID 和密碼，以及電路板的私有金鑰和憑證。

  2. 開啟 freertos/vendors/vendor/boards/board/aws_demos/config_files/aws_demo_config.h、註解 #define CONFIG_MQTT_DEMO_ENABLED，然後定義 CONFIG_OTA_UPDATE_DEMO_ENABLED。

  3. 建置解決方案並確認過程中沒有發生任何錯誤。

  4. 啟動終端機模擬器，並使用以下設定來連線到您的電路板：

    • 傳輸速率：115200

    • 資料位元：8

    • 同位：無

    • 停止位元：1

  5. 在您的主機板上執行專案，確認它可以連線到 Wi-Fi 及 AWS IoT MQTT 訊息中介裝置。

執行時，終端機模擬器應會顯示與以下內容相似的文字：
