X-CUBE-AZURE-H7S

概要

The X-CUBE-AZURE-H7S Expansion Package consists of an adaptation of the Azure^® RTOS IoT reference integration ported on the STM32H7S78-DK Discovery kit acting as an end device.

X-CUBE-AZURE-H7S proposes a sample application that configures the network connectivity parameters and illustrates the various ways for a device to interact with the Microsoft^® Azure^® IoT Hub. The application shows how a client application connects to the Azure^® IoT Hub to publish device state and telemetry data, and receive device configuration from the cloud. The application handles Azure^® messages, methods, and twin update commands. This allows, from Azure^® IoT Central, the reception of telemetry data, the start-and-stop of telemetry data emission, the remote control of the user LED state, and the change of the telemetry interval.

The device credentials and settings are encrypted by a derived hardware unique key (DHUK) and saved in the external flash memory of the STM32H7S78-DK Discovery kit.

The user application is stored encrypted in the external flash memory, and loaded into the external RAM by the secure bootloader. The traffic to and from the external RAM is encrypted on-the-fly by the MCU hardware, keeping the copy of the user application and data secret to the device.
