Overview

The uart_interrupt example shows how to use uart driver in interrupt way:

In this example, one uart instance connect to PC through uart, the board will send back all characters that PC send to the board.

Note: The example echo every 8 characters, so input 8 characters every time.

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

  • Micro USB cable
  • LPCXpresso55s69 board
  • Personal Computer

Board settings

No special settings are required.

Prepare the Demo

Note: MCUXpresso IDE project default debug console is semihost

  1. Connect a micro USB cable between the host PC and the LPC-Link USB port (P6) on the target board.
  2. Open a serial terminal with the following settings:
    • 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.

Running the demo

When the demo runs successfully, the log would be seen on the terminal like:
