Multiple Interrupts

Right GTS doesn't work at all. (yes we have tested the GTS after we fixed the resistors problem and it works fine)

Can someone see where I messed up??? Copied the code from Kevin Watson's Encoder Code.

I can't really make out what's going on, but I did see that you were calling printf() in your interrupt service routine, which can cause problems. A much better quick-and-dirty way to signal the outside world is to just send a single character using Write_Serial_Port_One(), which executes much faster. It's as simple as this:

Write_Serial_Port_One('*');

Fix this one problem and let us know if it works.
