Overview
========
The gpt_timer project is a simple demonstration program of the SDK GPT driver. It sets up the GPT
hardware block to trigger a periodic interrupt after every 1 second. When the GPT interrupt is triggered
a message a printed on the UART terminal.
Toolchain supported
===================
- IAR embedded Workbench 8.50.1
- GCC ARM Embedded 9.2.1
Hardware requirements
=====================
- Micro USB cable
- MIMX8MQ6-EVK board
- J-Link Debug Probe
- 12V power supply
- Personal Computer
Board settings
==============
No special is needed.
Prepare the Demo
================
1. Connect 12V power supply and J-Link Debug Probe to the board, switch SW701 to power on the board
2. Connect a USB cable between the host PC and the J1701 USB port on the target board.
3. Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
4. Download the program to the target board.
5. 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:
~~~~~~~~~~~~~~~~~~~~~
