Fazer download, compilação, instalação e execução de demonstração OTA do FreeRTOS no CC3220SF-LAUNCHXL da Texas Instruments
Importante
Essa integração de referência está hospedada no repositório Amazon-FreeRTOS, que está preterido. Recomendamos começar aqui ao criar um novo projeto. Se você já tem um projeto FreeRTOS existente baseado no repositório Amazon-FreeRTOS que está preterido, consulte o Guia de migração do RTOS repositório Github gratuito da Amazon.
Como fazer download do FreeRTOS e do código de demonstração OTA
-
É possível baixar o código-fonte no site GitHub em https://github.com/FreeRTOS/FreeRTOS
.
Para criar o aplicativo de demonstração
-
Siga as instruções em Comece com o Free RTOS para importar o projeto
aws_demospara o Code Composer Studio, configurar o endpoint da AWS IoT, o SSID e a senha do Wi-Fi, uma chave privada e um certificado para a placa. -
Abra
freertos/vendors/vendor/boards/board/aws_demos/config_files/aws_demo_config.h#define CONFIG_CORE_MQTT_MUTUAL_AUTH_DEMO_ENABLEDe definaCONFIG_OTA_MQTT_UPDATE_DEMO_ENABLEDouCONFIG_OTA_HTTP_UPDATE_DEMO_ENABLED. -
Crie a solução e verifique se ela foi criada sem erros.
-
Inicie um emulador de terminal e use as seguintes configurações para se conectar à placa:
-
Taxa de baud: 115200
-
Bits de dados: 8
-
Paridade: nenhum
-
Bits de parada: 1
-
-
Execute o projeto na placa para confirmar se ele pode se conectar ao Wi-Fi e ao agente de mensagens MQTT da AWS IoT.
Quando executado, o emulador de terminal deve exibir um texto como o seguinte:
