rt fifo in an interrupt routine

Highlighted

I was wondering if the writing to an RT fifo inside of an interrupt routine was supposed to work? I create the fifo in the application vi and call the fifo write within a gpio fifo, but every time the fifo write is called the micro hangs. I using the Luminary micro eval board.  Thanks

Hi Ed,

 

Could you post some example code so that I can see what you are doing?
