I'm sorry guys. I was very very tired. I have a crazy learning curve, and sometimes when I push wide-open-throttle for too long cuz I've really bitten off too much, I burn out and crash. I've been asleep since Saturday... five weeks was just too long. I really do appreciate all the help! You all are great!

Can I use EUSART over BT HC-05? I would assume not since one is UART and one is EUSART...

If that's the case my problem is then:

1. I cant use DT's interrupts without corrupting my serin/serout. And I have to assume it'll corrupt hserin/hserout as well.
2. I can't use ON INTERRUPT cuz it'll miss pulses during even the shortest waits. This is even worse than #1 since the machine will be lost.

If I use serial interrupts and program loops, which from how arduino is structured, I assume that's what happens on that platform, wouldn't that solve my problem once and for all?
