Overview
========
The gpt_capture project is a simple demonstration program of the SDK GPT driver's input capture feature.
The example sets up a GPT channel for rise-edge capture. Once the input signal is received,
this example will print the capture value.
Toolchain supported
===================
- IAR embedded Workbench 9.30.1
- Keil MDK 5.37
- GCC ARM Embedded 10.3.1
- MCUXpresso 11.6.0
Hardware requirements
=====================
- Micro USB cable
- EVK-MIMXRT1020 board
- Personal Computer
Board settings
==============
Connect input signal to J18-2 Test Point.
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 example runs successfully, following information can be seen on the terminal:

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.
