Getting started with the X-CUBE-GNSS1 global navigation satellite system

Introduction

The

X-CUBE-GNSS1

is an expansion software package for STM32Cube.

The software runs on the STM32 and includes drivers for the

middleware for the NMEA protocol support, and RTOS (Azure® RTOS ThreadX or FreeRTOS™) for task scheduling to ensure a

better asynchronous message parsing.

It is built on top of the

STM32Cube

The software comes with sample implementations for the drivers running on the

connected to a NUCLEO-F401RE, NUCLEO-L476RG, NUCLEO-L073RZ, or

The software also includes a sample application for assisted GNSS provided by the

is tailored for the

B-L475E-IOT01A
