I removed it and the code compiles. </p> http://forums.leaflabs.com/topic.php?id=1155#post-7115 Mon, 07 Nov 2011 21:01:50 +0000 hbdgas 7115@http://forums.leaflabs.com/ <p>Thanks for the reply. I tried some divide and conquer by commenting out all but the most basic parts of the code, and still got the error. I will try getting Blink to work tomorrow when I'm back in the lab. Tonight a friend also suggested that something may have happened to the IDE from the look of the message. </p> http://forums.leaflabs.com/topic.php?id=1155#post-7113 Mon, 07 Nov 2011 18:40:45 +0000 gbulmer 7113@http://forums.leaflabs.com/ <p>Have you checked the IDE is still working by uploading something simple like Blink?</p> <p>Have you tried 'divide and conquer' to reduce the problem cause?<br /> By this I mean something very simple:<br /> 1. make a backup copy of your code, then<br /> 2. delete as much of it as you can until that error disappears, then<br /> 3. start putting pieces of the original back in until it breaks again, and you are looking at one line of code that cause the error. </p> http://forums.leaflabs.com/topic.php?id=1155#post-7110 Mon, 07 Nov 2011 13:12:05 +0000 hbdgas 7110@http://forums.leaflabs.com/ <p>Hello,</p> <p>I am trying to write some audio sampling code for a school project, and when I hit the compile button in the IDE I receive the following error:</p> <p>Something went wrong.
