LPC-link2 external trigger for HSADC using SCT event

I am currently using the LPX-link2 for signal collection. And would like to add a external trigger feature. I read the post LPC-link2 external trigger for HSADC jeremyzhou ravi thakur and follow the instruction, I have done bellowing:


1. import the zip file and change the main function into jeremyzhou's code, then build and run it in debug mode
2. trigger it using a 3 V DC signal, with half second on and half second off, but the LED not turn on
3. check P1_13 by using GPIO mode, which shows that is the correct pin.

I am a bit confused and will be very appreciate if anyone give a clue in how to make it work.
