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
- EVK-MIMXRT1020 board
- Personal Computer
Board settings
No special settings are required.
Prepare the Demo
- Connect a USB cable between the PC host and the OpenSDA USB port on the board.
- Open a serial terminal with these settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
- Download the program to the target board.
- 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 !

And you will find the user LED is taking turns to shine.
Note:
To debug in qspiflash, following steps are needed:
1. Select the flash target and compile.
2. Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J23.
3. Start debugging in IDE.
- Keil: Click "Download (F8)" to program the image to qspiflash first then clicking "Start/Stop Debug Session (Ctrl+F5)" to start debugging.
