https://devzone.nordicsemi.com/f/nordic-q-a/34110/sdk-15-saadc-softdevice-issues-with-ppiHello all, I am using the latest SDK 15 and softdevice v5 (downgraded from v6 thought it was causing issues) on the NRF52 DK. When I build my application it states: Compiling ‘nrf_sdh_soc.c’ Compiling ‘nrf_sdh_ble.c’ Compiling ‘nrf_sdh.c’ Output/Releaseen-USTelligent Community 13Fri, 11 May 2018 02:23:55 GMThttps://devzone.nordicsemi.com/thread/131653?ContentTypeID=1Fri, 11 May 2018 02:23:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df0e203d-dc8b-4112-b9e6-f4c1a5c6535aewizardii<p>Thanks!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/131334?ContentTypeID=1Tue, 08 May 2018 09:38:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9b34a6b6-e1ea-4c15-93a8-61fcde3dd25eStian R&#248;ed Hafskjold<p>Yes, you can read more about nrfx here: <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/migration.html?cp=4_0_0_1_9_4_0#migration_drivers_nrfx">http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/migration.html?cp=4_0_0_1_9_4_0#migration_drivers_nrfx</a></p> <p>&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/131117?ContentTypeID=1Mon, 07 May 2018 06:17:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:24371727-0694-42cb-8b18-2418e4c41d0bewizardii<p>Figured it out meant to include the `nrfx_ppi.c` file I had `nrf_drv_ppi.c` included, didn&#39;t know there were two. However it looks like my callback statement for SAADC is never called.</p><div style="clear:both;"></div>
