I noticed the same behavior on pin 24 a couple of weeks ago; it was a simple PIN_MAP bug.

I'd still label this a bug, as the intended behaviour at initialisation, is that all timers are set to TIMER_PWM ( <a href="http://leaflabs.com/docs/lang/api/hardwaretimer.html" rel="nofollow">http://leaflabs.com/docs/lang/api/hardwaretimer.html</a> ), but at least it's a bug with a workaround.</p> <p>I added this above Timer4.setPrescaleFactor(PRESCALE); in my code:</p> <blockquote><p><code>Timer4.setChannelMode(4,TIMER_PWM);</code> </p></blockquote> <p>EDIT: I tested a few other pins, and didn't need the 'work around' but I'm happy enough just using pin 24 with the 'work around' </p> http://forums.leaflabs.com/topic.php?id=683#post-3904 Tue, 15 Mar 2011 22:13:49 +0000 Darth Maker 3904@http://forums.leaflabs.com/ <p>I'll point you to this thread, where I had the same problem.</p> <p><a href="http://forums.leaflabs.com/topic.php?id=611" rel="nofollow">http://forums.leaflabs.com/topic.php?id=611</a></p> <p>For some reason Timer4 doesn't get initialized properly, so you just add that code in. </p> http://forums.leaflabs.com/topic.php?id=683#post-3893 Tue, 15 Mar 2011 07:34:36 +0000 crenn 3893@http://forums.leaflabs.com/ <p>That is the one thing I didn't try, which was different timers/pins.

I forgot to measure if there was any output on the pin, however, this is the code I've tested with. If I compile the same code in v0.0.8, I get the expected result (which is the servo moving).</p> <p><a href="http://www.crennsmind.com/Code/Maple/Servo/Servo_Control.txt" rel="nofollow">http://www.crennsmind.com/Code/Maple/Servo/Servo_Control.txt</a><br /> <a href="http://www.crennsmind.com/Code/Maple/Servo/Servo_Test.txt" rel="nofollow">http://www.crennsmind.com/Code/Maple/Servo/Servo_Test.txt</a> </p>
