  1. Connect a micro USB cable between the host PC and the LPC-Link USB port (J8) on the target board.

  2. Open a serial terminal with the following settings:

    • 9600 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

Running the demo#

  1. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

PINT Pattern Match example

PINT Pattern match events are configured

Press corresponding switches to generate events

  1. This example configures “Pin Interrupt 0” to be invoked when ISP switch is pressed by the user. Bit slice 0 is configured as an endpoint in sticky falling edge mode. The interrupt callback prints “PINT Pin Interrupt 0 event detected. PatternMatch status = 1”.

    “Pin Interrupt 2” is configured to be invoked when rising edge on ISP, USER is detected. The interrupt callback prints “PINT Pin Interrupt 2 event detected. PatternMatch status = 100”. Bit slices 1 configured to detect sticky rising edge. Bit slice 2 is configured as an endpoint.
