https://devzone.nordicsemi.com/f/nordic-q-a/28699/inaccurate-timer-interruptI am working on nRF52840 Preview DK. I want to generate a square wave with accuracy of ON and OFF time = 1 microsecond using timer for driving stepper motor DRB8825. I am using SDK version : nRF5_SDK_14.2.0_17b948a I have performed below set ofen-USTelligent Community 13Wed, 20 Dec 2017 13:00:01 GMThttps://devzone.nordicsemi.com/thread/113753?ContentTypeID=1Wed, 20 Dec 2017 13:00:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a05c6d40-faa4-4951-8700-ec833bfa7426AmbystomaLabs<p>It should be apparent that a 64MHz processor can not process microsecond interrupts. Apparently this is not obvious to people (it should be) since this comes up regularly.</p> <p>Please search through the devzone and you will find countless questions on microsecond gpio activity and how it CAN NOT be done via interrupts with a 64MHz processor. It can only be done via PPI/GPIOTE.</p><div style="clear:both;"></div>
