Hardware requirements

  • Micro USB cable

  • LPCXpresso845MAX board

  • Personal Computer

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J4) on the board

  2. Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):

    • 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.

The following lines are printed to the serial terminal when the demo program is executed.

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 SW1 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 SW1, SW2 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.
