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.
|
|
|
|
Toolchain supported
|
|
===================
|
|
- IAR embedded Workbench 9.30.1
|
|
- Keil MDK 5.37
|
|
- GCC ARM Embedded 10.3.1
|
|
- MCUXpresso 11.6.0
|
|
|
|
Hardware requirements
|
|
=====================
|
|
- Mini/micro USB cable
|
|
- EVK-MIMXRT1020 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 !
|
|
....................
|
|
....................
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
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.
