Hello Henrik,

I tried to compile the original DT Interrupt file linked from the DT Interrupts tab above. It generated the same error as I listed in my first post. It says that the "INTHAND" was not previously defined. As you can see from the code listed on the DT Interrupts page, INTHAND was defined. It is not a processor problem because it reproduces with different processors. I am using the PIC18F46K80. It does not complain about the INTLHAN definition so I don't know what is going on here. I removed all my files and tried to compile just the original DT interrupts and got the same error.

Thanks,

Paul
