https://devzone.nordicsemi.com/f/nordic-q-a/39712/interrupt-sometime-lostI use one motor to drive one object move back and forth in a straight line, with two hall ic(XC3202) at the boundary points at both ends. The motor turn when the object reaches one detecting point. I use interrupt to detect the object reach the boundaryen-USTelligent Community 13Tue, 23 Oct 2018 11:15:41 GMThttps://devzone.nordicsemi.com/thread/154055?ContentTypeID=1Tue, 23 Oct 2018 11:15:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9a0d3347-57ef-4512-b8bc-d674624de6cbVidar Berg<p>Hi,</p> <p>Have you tested/considered using the .high_accuracy mode (IN_EVENT rather than PORT event)? You can enable it by passing &#39;True&#39; to the&nbsp;<span>GPIOTE_CONFIG_IN_SENSE_HITOLO() macro.&nbsp;</span>It does increase the base current consumption by ~20uA, but guess&nbsp;it would be negligible compared&nbsp;what you use to&nbsp;power the motor.&nbsp;</p> <p>BLE events&nbsp;can delay execution of lower priority ISRs, but not by much. Please refer to the &quot;Bluetooth low energy processor usage patterns&quot; in SDS if you want&nbsp;exact numbers&nbsp;(<a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.sds/dita/softdevices/s130/processor_avail_interrupt_latency/ble_usage_patterns.html?cp=2_3_1_0_15_2_2">link</a>).</p> <h1></h1> <p>&nbsp;&nbsp;</p><div style="clear:both;"></div>
