My aim is to use the  compass only. I have followed the instructions on <a href="https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Hat/ENVII_HAT/Arduino/ENVII_HAT" target="_blank" rel="noopener noreferrer nofollow ugc">https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Hat/ENVII_HAT/Arduino/ENVII_HAT</a></p>

Step 2. Refer How to install library<br />
[<a href="http://wiki.seeedstudio.com/How_to_install_Arduino_Library" target="_blank" rel="noopener noreferrer nofollow ugc">http://wiki.seeedstudio.com/How_to_install_Arduino_Library</a>] to install library for<br />
Arduino.<br />
Step 3. Create a new Arduino sketch and paste the codes below to it or open the<br />
