I'm building a gps controlled clock out of 7-segment led displays, and thought it'd be cool to use the pulse per second from the gps as an interrupt to drive an arduino to go fetch new data.
I hooked up 2 different EM-406A's, and neither one seems to have voltage on the pps pin. Using the SiRFDemo software I can see I have a valid fix, and indeed the red led on the 406 itself is flashing. I hooked up an LED just as I had with my venus gps (which worked as I expected), and this will not do anything. (pps + led - ground) (Tapping the pps wire to +5v does light the led, so I don't have it in backwards or anything)
I checked continunity on the 406 breakout board, and it's fine.
Any ideas? Do I need to enable it somehow?
