Overview

The PIT project is a simple demonstration program of the SDK PIT driver. It sets up the PIT hardware block to trigger a periodic interrupt after every 1 second. When the PIT interrupt is triggered a message a printed on the UART terminal and an LED is toggled on the board.

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 PC host and the OpenSDA USB port on the board.
  2. Open a serial terminal with these 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 example.

Running the demo

These instructions are displayed/shown on the terminal window:

Starting channel No.0 ...
 Channel No.0 interrupt is occurred !
 Channel No.0 interrupt is occurred !
 Channel No.0 interrupt is occurred !
