Appears to be working nice, resetting at desired preload value. In fact is resetting at PRELOAD - CALIB (which is 4 in my setup) but I presume this is OK. I can add CALIB to PRELOAD or just set CALIB = 0.</SPAN><BR /><BR /><SPAN>The question is I have put a NOP in SysTick_Handler() and I'm trying to measure somehow the time between 2 interrupt hits.</SPAN><BR /><SPAN>On some other MCU environments, I had a simulator that use a "StopWatch" cycle counter so I can "measure" the ticks between 2 breakpoints.</SPAN><BR /><BR /><SPAN>How can I do something similar in LPCExpresso? I mean software, because I can put my scope to measure two consecutive pin toggles :)</SPAN><BR /><BR /><SPAN>Thanks,</SPAN></BODY></HTML> Wed, 15 Jun 2016 23:02:58 GMT https://community.nxp.com/t5/LPCXpresso-IDE/Debug-cycle-counter-stopwatch/m-p/528406#M924 lpcware 2016-06-15T23:02:58Z Re: Debug cycle counter, stopwatch https://community.nxp.com/t5/LPCXpresso-IDE/Debug-cycle-counter-stopwatch/m-p/528407#M925 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by 1234567890 on Thu Jan 30 10:03:52 MST 2014</STRONG><BR /><SPAN><SPAN>See </SPAN><A class="jive-link-external-small" href="https://community.nxp.com/external-link.jspa?url=http%3A%2F%2Fwww.lpcware.com%2Fcontent%2Fforum%2Fcortex-m0-instruction-cycle-count" rel="nofollow" target="_blank">http://www.lpcware.com/content/forum/cortex-m0-instruction-cycle-count</A></SPAN></BODY></HTML> Wed, 15 Jun 2016 23:02:59 GMT https://community.nxp.com/t5/LPCXpresso-IDE/Debug-cycle-counter-stopwatch/m-p/528407#M925 lpcware 2016-06-15T23:02:59Z
