Overview

CMSIS-Driver defines generic peripheral driver interfaces for middleware making it reusable across a wide range of supported microcontroller devices. The API connects microcontroller peripherals with middleware that implements for example communication stacks, file systems, or graphic user interfaces. More information and usage method please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.

The cmsis_uart_interrupt_transfer example shows how to use uart cmsis 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

  • Mini/micro USB cable
  • EVKB-IMXRT1050 board
  • Personal Computer

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a USB cable between the host PC and the OpenSDA USB port 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 OpenSDA terminal like:

Lpuart CMSIS interrupt example
Board receives 8 characters then sends them out
Now please input:

When you input 8 characters, system will echo it by LPUART and them would be seen on the OpenSDA terminal.
