There is no example of using this driver in the SDK, but maybe the code in <a href="https://devzone.nordicsemi.com/f/nordic-q-a/57681/hts-221-error-4-nrf_error_no_mem">this post</a> may provide you with a starting-point.</p> <p>There is also a driver for this sensor in the <a href="https://github.com/NordicSemiconductor/Nordic-Thingy52-FW/blob/master/source/drivers/drv_hts221.c">Thingy:52 FW</a>.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
