Microchip Examples for Google Cloud Platform IOT Core

Summary

This project contains examples and tools for setting up a secure IOT node with IOT Core using the ATECC508A or ATECC608A and WINC1500 with a selection of energy efficent microcontrollers.

Security Devices:

Connectivity:

  • ATWINC1500 - 802.11 b/g/n Module with integrated TLS 1.2 stack
  • ATSAMW25 - Integrated module featuring ATWINC1500 + ATSAMD21G18A + ATECC508A

Microcontrollers or SOCs:

  • ATSAMD21 (ARM Cortex-M0)
  • ATSAMG55 (ARM Cortex-M4)
  • ATSAMW25 (ARM Cortex-M0)
  • Raspberry Pi

Project Organization

These examples were built with Atmel Studio 7

ATSAMD21 Quick Start /boards/gcp_iot_core_samd21.atsln

ATSAMG55 Quick Start /boards/gcp_iot_core_samg55.atsln

ATSAMW25 Quick Start /boards/gcp_iot_core_samw25.atsln

Getting Started

The first step is ensuring that you have a Google Cloud IoT Core account set up with IoT core.

The tutorials will walk you through the initial configuration of your account and creation of your first device registry
