https://devzone.nordicsemi.com/f/nordic-q-a/35789/lis2dh-interface-with-nrf51822-reading-ff-values-in-custom-boardI am interfacing LIS2DH with nrf51822. I am using 12.3.0 SDK and 130 V2 for development. I have successfully interfaced LIS2DH eval board with Nrf51822 eval board (waveshare BLE 400) When I try to run the code on my custom board with exact same connectionen-USTelligent Community 13Wed, 27 Jun 2018 11:32:25 GMThttps://devzone.nordicsemi.com/thread/137872?ContentTypeID=1Wed, 27 Jun 2018 11:32:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc7b39bf-cfe1-46a1-a3b5-8635d5fb2290Ketan Bhaid<p>Hi Ketiljo, I have shared schematic and gerber could you please check&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137748?ContentTypeID=1Tue, 26 Jun 2018 16:12:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:515aa566-de5b-417f-bfce-0494c058be0eKetan Bhaid<p>yes board is advertising / working properly</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137747?ContentTypeID=1Tue, 26 Jun 2018 16:12:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dbabdb47-ecc6-4fbe-ad35-65151dd1c976Ketan Bhaid<p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/DipTrace-Schematic-_2D00_-nordicBLE-V2.0.pdf">devzone.nordicsemi.com/.../DipTrace-Schematic-_2D00_-nordicBLE-V2.0.pdf</a><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/BLE2.0_5F00_top-copper.pdf">devzone.nordicsemi.com/.../BLE2.0_5F00_top-copper.pdf</a><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/BLE2.0_5F00_bottom-copper.pdf">devzone.nordicsemi.com/.../BLE2.0_5F00_bottom-copper.pdf</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137745?ContentTypeID=1Tue, 26 Jun 2018 16:05:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:65041c7a-deba-4ff5-96d6-ed9dcfe9cec3kphalak<p>insert link or image</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137744?ContentTypeID=1Tue, 26 Jun 2018 16:04:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:803d1e46-94c2-4eb3-81c9-c0251d8b2366Ketan Bhaid<p>where to post the files?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137694?ContentTypeID=1Tue, 26 Jun 2018 13:18:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7e5138ee-df52-4e7a-89a5-56cf721ae998kphalak<p>Are all other features of your custom board working properly?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137683?ContentTypeID=1Tue, 26 Jun 2018 12:46:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d6e74855-4694-4423-9ba7-abd7c99978c1ketiljo<p>Can you post the schematic and layout (gerbers)?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137658?ContentTypeID=1Tue, 26 Jun 2018 11:23:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:103377a9-a53b-450d-b867-63cd1b75d442Ketan Bhaid<p>I am using SPI</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/137643?ContentTypeID=1Tue, 26 Jun 2018 10:42:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:19cd8ffd-7d44-4fc0-8254-49d92dc9b07dketiljo<p>If you&#39;re using the LIS2DH with the I2C interface, you&#39;re probably missing the pull up resistors.
