Hi,
I am using the LPCXpresso board with LPC1549. I have got a wakeup switch on the board which i want to use as the hardware trigger for the ADC but when i assign PINTRIG0 or PINTRIG1 to the pin connected to the wakeup button on the board which is PO0_17, i cannot use it as a trigger. For testing that pin as the trigger i toggle the onboard LED to test its triggering but the LED does not toggle. I cannot get any detailed information wheather PO0_17 can be used as an external trigger or not. I need help on this.
Thanks,
Ruchika
