Hi
I just did a fresh install of VS 2010 and VM. I have started a new project with Teensy 3 and found that the intellisense does not work. If I switch the board to Uno, it works but if I switch back it is gone again.
The project compiles and downloads fine.

I think they are all done correctly as the sketch compiles OK.
Here is the contents of the vsarduino.h file

Sorry, I had it switched to Uno so that I can work.

Sure no problem, thanks a lot man.

Sorry for the delay

Hi,

Thanks for testing good to hear it's working (sort of)

The "Errors" output window in vs will never be 100% perfect but you are right that it was missing definitions causing many errors to display. 

We have refreshed the 1401.12 beta build on codeplex. Please click it and run the installer again with vs closed.

The fix affects intellisense for both arduino and teensy boards when then Teensy Ide is selected. With more time and testing and maybe some help from Paul we should be able to improve it further.

Look forward to an update

I know it's not important but it would be good to make it better if possible. 

How many errors are showing? I had 11
