I'm developing an app on an M3 that requires I run a run a periodic task every 500 microseconds. Currently I'm using a periferial timer and isr_evt_set to wakup my high priority task. This all works fine, but I'm wondering if I could just setup the systick for this higher rate and use os_ivt_wait for sleeping my task. My reasoning is RTX is already running its scheduling code every time I set the event flag from my timer ISR so would it not make sense just to have RTX tick at the same rate and just eliminate the extra timer ISR? What I don't want to do is create any extra overhead by having RTX tick at this higher rate. Opinions?
Thanks Mark
