Scarica, crea, esegui il flashing ed esegui la demo OTA FreeRTOS su Texas Instruments CC3220SF-LAUNCHXL
Importante
Questa integrazione di riferimento è ospitata nel repository Amazon-FreeRTOS che è obsoleto. Consigliamo di iniziare da qui quando crei un nuovo progetto. Se disponi già di un progetto FreeRTOS esistente basato sull'ormai obsoleto repository Amazon-FreeRTOS, consulta ilGuida alla migrazione del repository Github di Amazon-FreeRTOS.
Per scaricare FreeRTOS e il codice demo OTA
-
È possibile scaricare il codice sorgente dal GitHub sito all'indirizzo https://github.com/FreeRTOS/FreeRTOS
.
Per creare l'applicazione demo
-
Seguire le istruzioni in Nosu FreeRTOS per importare il progetto
aws_demosin Code Composer Studio, configurare l'endpoint AWS IoT, l'SSID Wi-Fi e la password, una chiave privata e un certificato per la scheda. -

Creare la soluzione e accertarsi che venga compilata senza errori.
-
Avviare un emulatore di terminale e utilizzare le seguenti impostazioni per effettuare la connessione alla scheda:
-
Velocità in baud: 115200
-
Bit di dati: 8
-
Parità: nessuna
-
Bit di stop: 1
-
-
Eseguire il progetto sulla scheda per accertarsi che riesca a connettersi alla rete WiFi e al broker di messaggi MQTT AWS IoT.
Durante l'esecuzione, l'emulatore di terminale dovrebbe visualizzare testo simile al seguente:
