Hi

I am running version 4.135 and am trying to use INT_RA.
When I do, I get the following error - Invalid pre-processor directive

I am trying to use a PIC16f877a and a pic18f452.

How do I get around this error?

Thanks

Neither of those chips _have_ an INT_RA....

The only error is trying to use a feature the chip doesn't have. Look at the data sheet. It lists what interrupts a chip has.

The compiler can't give the chip features it doesn't have, this is why the data sheet must always be your staring point for 'what the chip can do'.
