https://test-devzone.nordicsemi.com/f/nordic-q-a/88960/cmsis-dsp-version-in-sdkDear All, I use nRF52 SDK 17.1 for a bunch of projects with nRF52840. CMSIS DSP Library v1.6.0 (18. March 2019) is included in that SDK. I see that in the meantime there is a CMSIS DSP Library version 1.10.0 (see https://arm-software.github.io/CMSIS_5en-USTelligent Community 13 Non-ProductionWed, 15 Jun 2022 12:19:23 GMThttps://test-devzone.nordicsemi.com/thread/372568?ContentTypeID=1Wed, 15 Jun 2022 12:19:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:deacc87c-bfef-469d-a846-da09c283781buser14926<p>Hi,</p> <p>The CMSIS DSP libraries are provided by ARM, not by Nordic. They are usually available in the release section in this GitHub:&nbsp;<a href="https://github.com/ARM-software/CMSIS_5">https://github.com/ARM-software/CMSIS_5</a>, however, I could not find the lib directory in the latest release. You may build it from source, use the sources directly, or ask in the <a href="https://community.arm.com/">ARM&nbsp;community</a>&nbsp;where you can get the libs.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
