But even if it did, in this case my sensor's busted. Burned on extraction. </p> <p>It looks like the PVision library is working just fine on Maple, only had to change the include from WConstants.h to wirish.h. </p> http://forums.leaflabs.com/topic.php?id=12828#post-27658 Mon, 08 Jul 2013 06:12:05 +0000 jamiezigelbaum 27658@http://forums.leaflabs.com/ <p>I'm porting the arduino PVision library (<a href="https://github.com/joksan/Wii_Remote_Camera_Mouse/tree/master/PVision" rel="nofollow">https://github.com/joksan/Wii_Remote_Camera_Mouse/tree/master/PVision</a>) to Maple which will make it much easier to read from a Wiimote / Pixart IR sensor (no externals save for two pullup resistors). </p> <p>You can see my code here: <a href="https://github.com/NoContour/wiicamMaple" rel="nofollow">https://github.com/NoContour/wiicamMaple</a></p> <p>Looking at the output from scl on my scope and it seems to idle low — I am learning the spec for i2c now, it seems to me it should be high. I am not able to read from the IR sensor and wondering if this has something to do with it.</p> <p>Thanks for any help. </p>
