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
===================
- Keil MDK 5.24a
- IAR embedded Workbench 8.22.2
- GCC ARM Embedded 7-2017-q4-major
- MCUXpresso10.2.0
Hardware requirements
=====================
- Mini/micro USB cable
- MAPS-KS22F256 board & MAPS-DOCK board
- Personal Computer
Board settings
==============
The pit example is configured to use UART1 with PTE0 and PTE1 pins. To make JLink serial
device work, the jumpers on MAPS-DOCK board should be set as following:
- JP7 on MAPS-Dock: UART0 related jumpers connected
Prepare the Demo
================
1. Connect a mini USB cable between the PC host and the USB port (CN14) on MAPS-DOCK board.
2. Open a serial terminal on PC for JLink serial device 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 demo.
Running the demo
================
These instructions are displayed/shown on the terminal window:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Starting channel No.0 ...
Channel No.0 interrupt is occured !
Channel No.0 interrupt is occured !
Channel No.0 interrupt is occured !
....................
....................
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
And you will find the LED RED1 is taking turns to shine.
