Looking to use optoisolated MOSFETS instead, much better to drive an ignition coil with :) </p> http://forums.leaflabs.com/topic.php?id=13465#post-28655 Sun, 01 Sep 2013 10:25:13 +0000 ala42 28655@http://forums.leaflabs.com/ <p>You can specify the period of the timer and can specify the high time for each of the timers for output channel.<br /> I hope you do not try to pulse mechanical relays with 600Hz or more. </p> http://forums.leaflabs.com/topic.php?id=13465#post-28654 Sun, 01 Sep 2013 06:00:24 +0000 vfr800nut 28654@http://forums.leaflabs.com/ <p>Hi All,</p> <p>Probably a complete noobie question but here goes.</p> <p>I noticed timer PWM mentioned in this thread,<br /> <a href="http://forums.leaflabs.com/topic.php?id=1222#post-7400" rel="nofollow">http://forums.leaflabs.com/topic.php?id=1222#post-7400</a></p> <p>I'm looking to turn 4 different relays on for x milliseconds then off for y milliseconds. where x != Y. My present solution is using timers 3 and 4 with 4 interrupts on each, 2 on and 2 off via digitalwrite.</p> <p>Can the on and off times of timer PWM be allocated seperately to generate the required square wave (600-9KHz)? </p> <p>Has anybody got a more elegant solution for this ?</p> <p>Thanks </p>
