Can you provide the code? Also, have you tried 0.0.10 Beta? (see the blog for a link) </p> http://forums.leaflabs.com/topic.php?id=778#post-4670 Wed, 18 May 2011 20:47:18 +0000 rjgrahek 4670@http://forums.leaflabs.com/ <p>I had working code to do quadrature decoding based on the timer setup shown in thread posted 9 months ago by drinkdhmo "hardware quadrature decoding issues". The development was moved to a different computer. IDE version 009 was downloaded and installed on this machine. With this version of the IDE, the encoder output from the Timer only moves a few counts in each direction and behaves weird. The code works fine on IDE version 006. Is anyone else experiencing this type of problem or have a solution? </p>
