timer seems to stophttps://devzone.nordicsemi.com/f/nordic-q-a/37936/timer-seems-to-stopThe hardware is a custom board with a Rigado BMD300 module (which uses the nRF52832). I am using Softdevice S132. My code base started as the ble_app_uart peripheral example. To this I am trying to add SPI code to communicate with multiple SPI-to-UARTen-USTelligent Community 13Wed, 29 Aug 2018 20:09:38 GMTRE: timer seems to stophttps://devzone.nordicsemi.com/thread/146378?ContentTypeID=1Wed, 29 Aug 2018 20:09:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aad1ff8d-5bb8-470f-a246-549f5bad999cSteven Grunza<p>The answer turns out to be careful about cut-n-paste errors in the SPI controller management code.&nbsp; The SPI controller dedicated to the right side port had left-over references to the SPI controller dedicated to the left side.</p><div style="clear:both;"></div>RE: timer seems to stophttps://devzone.nordicsemi.com/thread/146349?ContentTypeID=1Wed, 29 Aug 2018 14:09:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9993ada9-9e4f-45a1-b2b0-a21c133a376fSteven Grunza<p>The timestamp variable is global.&nbsp; Making it volatile did not change the assembly code that was generated.</p> <p></p> <p>I think these are the relevant files.</p> <p></p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/0118.main.c">devzone.nordicsemi.com/.../0118.main.c</a></p> <p></p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/spi.c">devzone.nordicsemi.com/.../spi.c</a></p> <p></p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/84487.sdk_5F00_config.h">devzone.nordicsemi.com/.../84487.sdk_5F00_config.h</a></p> <p></p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/3683.main.h">devzone.nordicsemi.com/.../3683.main.h</a></p><div style="clear:both;"></div>RE: timer seems to stophttps://devzone.nordicsemi.com/thread/146210?ContentTypeID=1Wed, 29 Aug 2018 06:19:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e9676232-3e17-4bab-bd69-0d02ee419153Einar Thorsrud<p>Hi,</p> <p>Can you share more of your code?
