Since interrupts should be off while handling an interrupt, whatever you do in the handling needs to be quick and done before the next interrupt comes along. </div><div><br></div><div>Others, feel free to correct me, as my enthusiasm sometimes surpasses my knowledge. <br><br><div><span class="Apple-style-span" style="-webkit-tap-highlight-color: rgba(26, 26, 26, 0.296875); -webkit-composition-fill-color: rgba(175, 192, 227, 0.230469); -webkit-composition-frame-color: rgba(77, 128, 180, 0.230469); ">Jeff :)</span></div><div><span class="Apple-style-span" style="-webkit-tap-highlight-color: rgba(26, 26, 26, 0.296875); -webkit-composition-fill-color: rgba(175, 192, 227, 0.230469); -webkit-composition-frame-color: rgba(77, 128, 180, 0.230469); "><br></span></div></div><div><br>On Jul 26, 2014, at 16:09, Joe Fair <<a href="mailto:joe@fairanswers.com">joe@fairanswers.com</a>> wrote:<br><br></div><blockquote type="cite"><div><p>Ok.

<p>The loop I'm using detects a trigger pull, then a hit on the sensors. however, The pulse in function I'm using to sense IR ha a timeout of 1 second. If there is no inbound signal it is only checking got a trigger pull once a second.</p>
<p>So i need to use an interrupt, but does it matter if i use one on the trigger pull or the ir sensor? </p>
