Overview

The PLU combination project is a simple demonstration program of the SDK PLU driver. In this example, a number of GPIO pins are connected to PLU inputs and the LED is used to monitor the PLU outputs to demonstrate the configuration and use of the Programmable Logic Unit (PLU) to construct a combinational logic network.

SDK version

  • Version: 2.15.000

Toolchain supported

  • IAR embedded Workbench 9.40.1
  • Keil MDK 5.38.1
  • GCC ARM Embedded 12.2
  • MCUXpresso 11.8.0

Hardware requirements

  • Mini/micro USB cable
  • LPCXpresso55s69 board
  • Personal Computer

Board settings

PLU input pins connection:

  • P17_19 (GPIO1_8) to P18_20 (PLU_IN3).
  • P18_1 (GPIO1_9) to P17_12 (PLU_IN4).
  • P18_3 (GPIO1_10) to P17_10 (PLU_IN5).

PLU output pins connection:

  • P18_16 (PLU_OUT0) to P18_9 (LED_RED).
  • P18_14 (PLU_OUT1) to P18_7 (LED_GREEN).
  • P17_1 (PLU_OUT2) to P18_5 (LED_BLUE).

Prepare the Demo

Note: MCUXpresso IDE project default debug console is semihost

  1. Connect a micro USB cable between the PC host and the CMSIS DAP port(CN2 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):
    • 115200 baud rate
    • 8 data bits
    • No parity
    • One stop bit
    • No flow control
  3. Download the program to the target board.
  4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Expected Result Input source and LED status table:

PLU_IN5 PLU_IN4 PLU_IN3 LED_BLUE LED_GREEN LED_RED
0 0 0 off off off
0 0 1 off off on
0 1 0 off on off
0 1 1 on off off
1 0 0 off on on
1 0 1 on off on
1 1 0 on on off
1 1 1 on on on

The log below shows the output of the plu combination example in the terminal window:
