Hello folks,
I wish you all a healthy new year and and a lot of pleasant time also in this forum. ;-)

Ok, why the following error message appear?

'Invalid Pre-Processor directive' when using #int_rc ??
#int_rb is still working
In the manual (May 2003) on page 43 I find also an #int_rc. But it dosen't work, why?
What a pity, I could need four more ports like PB4-PB7.

Compiler version is 3.181

Thank you for any help

What PIC? If the PIC doesn't support it then you can't do it. Check the datasheet for the device.

Hello Mark,
Oh no, you're right.
I use a 18F452 and it supports interrupt only at port B.

I wished a better error description from the compiler like:
'command not supported by THIS device'
So I could see my mistake

But otherwise it show me that there are any kind of PICs that have these function also on port c. I have a look...

Thank you
