HMC5883L 2. BMP-085 3. L3G4200D 4.ADXL345 at least i need to get the HMC5883L-magnetometer readings please help me out theen-USTelligent Community 13Thu, 20 Feb 2020 16:39:23 GMThttps://devzone.nordicsemi.com/thread/235556?ContentTypeID=1Thu, 20 Feb 2020 16:39:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2a90dc8a-fb38-490a-b070-001ce8e8cbc6Kenneth<p>First of all you should get yourself an logic analyzer (e.g.&nbsp;<a href="https://www.saleae.com/">https://www.saleae.com/</a>) such that you can observe the serial data and compare with the datasheet of the sensor.</p> <p>Secondly I suggest to run these two examples as a starting point. The first example will identify the address of the sensor and ensure that the hardware is working. The second example can be used as a starting point to read and write to the sensor.</p> <p><a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/twi_scanner_example.html">https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/twi_scanner_example.html</a></p> <p><a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/twi_sensor_example.html">https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/twi_sensor_example.html</a></p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
