The line is in the wrong place.
Here is the entire ISR routine from the demo with the new line added:

}
} // End of main application loop
like your modification of your headfile is correct:




It looks
EPIR_SC0_DEF 0x48

Let me know if this helps.

Dear Tom,
i inserted the code as you said, but the code does not build. It says an error appears at the serial map.
I zip the src so you can have a look.

Other question:
how can i put the zmotion detection module on the board that came with the intrusion package?
I see no header, is there some instruction or should i go buying the detection devkit??

Dear Tom,
still no result. After i followed your latest instructions, the build reports a problem at the serial driver. No details.
Shall i send you the SRC or can you give me more insight on which files to open and start from?
Thanks,
Jacob
