USB humping dog email alert

[armoredcars]

I have a 631 and wanted to know if I could get it to sink one of the pins on the back and start the dog when I get an email.
I was thinking, and I might be completely wrong, that someone could add to the whatever language you use equivalent of :
If NewEmail > 0
then pinX = 0
else pinx = 1
endif
to the end of the code that runs when it checks for email.
Also I was wondering if the 631 could down 5v or if I'd have to hook up a transistor.

Another option would be to use the fan headers from the SCAB when used in conjunction with the CFA631. This would have more options in sending the right voltage / signal to the dog.

The SCAB thing looks awesome, but I'm kind of pressed for cash now. Trust me, as soon as I have the time/money I'm going to hack the sh!t out of that thing. Right now all I need is a basic on off, if I can get a single pin to ground as little as 1.2v I can figure the rest out in hardwiring to get the dog working.

The just use GPIO[0]. Look in the data sheet on page 10. It should be good for 0v or 5v (only use 100% or 0%) at around 20mA. You can test it with 631_WinTest.

If you can get that working, then I think CC2 might be coaxed into setting GPIO[0] based on e-mail status (not 100% sure).
