Wichtig

Diese Referenzintegration wird im Amazon-FreeRTOS-Repository gehostet, das veraltet ist. Wir empfehlen, dass Sie hier beginnen, wenn Sie ein neues Projekt erstellen. Wenn Sie bereits über ein bestehendes FreeRTOS-Projekt verfügen, das auf dem inzwischen veralteten Amazon-FreeRTOS-Repository basiert, lesen Sie dieLeitfaden zur Migration des kostenlosen RTOS Github-Repositorys von Amazon.

Um FreeRTOS und den OTA-Demo-Code herunterzuladen
So erstellen Sie die Demo-Anwendung:

  1. Folgen Sie den Anweisungen in Jetzt kostenlos durchstarten RTOS, um das aws_demos-Projekt in Code Composer Studio zu importieren, Ihren AWS IoT-Endpunkt, Ihre WLAN-SSID und Ihr WLAN-Passwort und einen privaten Schlüssel zu konfigurieren und ein Zertifikat für Ihr Board zu erstellen.

  2. Öffnenfreertos/vendors/vendor/boards/board/aws_demos/config_files/aws_demo_config.h, kommentieren#define CONFIG_CORE_MQTT_MUTUAL_AUTH_DEMO_ENABLED und definierenCONFIG_OTA_MQTT_UPDATE_DEMO_ENABLED oderCONFIG_OTA_HTTP_UPDATE_DEMO_ENABLED.

  3. Erstellen Sie die Lösung. Prüfen Sie, ob die Erstellung fehlerfrei ausgeführt wurde.

  4. Starten Sie einen Terminalemulator und verwenden Sie die folgenden Einstellungen, um sich mit Ihrem Board zu verbinden:

    • Baudrate: 115200

    • Datenbits: 8

    • Parität: Keine

    • Stop-Bits: 1

  5. Führen Sie das Projekt auf Ihrem Board aus, um zu überprüfen, ob es eine Verbindung mit dem WLAN und dem AWS IoT-MQTT-Nachrichten-Broker herstellen kann.

Bei der Ausführung sollte der Terminalemulator den folgenden Text anzeigen:
