Example Application for Hillcrest BNO080 Development Kit
This repository contains the example application for the Hillcrest BNO080 development kit.
The code runs on an ST Nucleo evaluation board combined with the BNO shield board by Hillcrest. This shield incorporates the BNO080 sensor hub, enabling SH-2 functionality for the demo system.
Requirements
- IAR Embedded Workbench for ARM (EWARM) version 7.4
- STM32F411 Nucleo board
- Hillcrest BNO080 Shield board
Setup
Clone this repository using the --recursive flag with git:
- git clone --recursive https://github.com/hcrest/bno080-nucleo-demo.git
Building the Code
- Use IAR EWARM to open the workspace, bno080-nucleo-demo/EWARM/Project.eww
- Select the sh2-demo-i2c or sh2-demo-spi project configuration.
- Run Project -> Rebuild All to compile the project.
Running the Application
- Mount the shield board on the Nucleo platform.
- Ensure all switches are set properly (switch positions vary based on whether SPI or I2C interface is used.)
- Connect the Nucleo board to the development PC via USB.
- In IAR EWARM, execute Project -> Download and Debug.
- Once the debugger is ready, click the Go button.
The application should print the SH-2 version numbers, then start reading and printing Rotation Vectors from the sensor hub:
