	Hi Faiths, VS 2012 C++ intellisense does not like some Arduino/Gcc syntax. Normally we recommend closing the intellisense errors tool window and using the red intellisense squiggles and/or F7. There are a couple of core arduino files which show errors, new.h is one of them. Thanks

	I haven't seen such errors among large amounts Arduino/Teensy library or application sources.

	This may be a bit silly. However, I had the same error message occur and it turned out I just forgot some parentheses. ie: myServo.read; // error myServo.read(); // awesome!!!

	However, now and for no apparent reason the error had returned.

There are a couple of core arduino files which show errors, new.h is one of them. Hi, As stated earlier the intellisense errors you see relating to the arduino core are items that certain versions of visual studio can not understand. You can reply on the output from the build/compile to be sure that these are false errors. Basically you just need to ignore the intellisense errors window as suggested earlier or you can use atmel studio and visual micro which will not show these errors. So to be clear. If the compile//build fails then the errors you see will be correct. Double click to go to the code in error. Thanks
