Descargue, compile, instale y ejecute la demostración de OTA de FreeRTOS en CC3220SF-LAUNCHXL de Texas Instruments
importante
Esta integración de referencia está alojada en el repositorio de Amazon-FreeRTOS, que está en desuso. Recomendamos empezar por aquí al crear un nuevo proyecto. Si ya tiene un proyecto FreeRTOS existente basado en el repositorio Amazon FreeRTOS, ahora obsoleto, consulte Guía de migración al repositorio RTOS Github gratuito de Amazon.
Para descargar FreeRTOS y el código de demostración de OTA
-
Puede descargar el código fuente desde el sitio de GitHub en https://github.com/FreeRTOS/FreeRTOS
.
