Overview
========
This project is used to work with LittleVGL GUI Guider. The GUI Guider generated
code is placed in the folder "generated". The example generated code shows a
button in the panel.
Toolchain supported
===================
- IAR embedded Workbench 9.30.1
- Keil MDK 5.37
- MCUXpresso 11.6.0
- GCC ARM Embedded 10.3.1
Hardware requirements
=====================
- Micro USB cable
- EVK-MIMXRT1020 board
- Adafruit TFT LCD shield w/Cap Touch
- Personal Computer
Board settings
==============
There are different versions of Adafruit 2.8" TFT LCD shields. The shields marked
v2.0 works directly with this project. For the other shields, please solder
the center pin of IOREF pads to the 3.3V pad, and solder the pads 11, 12, and 13.

Attach the LCD shield to the board.
Prepare the Demo
================
1. Connect a micro USB cable between the PC host and the J6 micro USB port on the board.
2. Build the project.
3. Download the program to the target board.
4. Reset the SoC and run the project.
Running the demo
================
If this example runs correctly, the sample GUI is displayed.
Known issue: The MCU is not able to generate hardware reset of the LCD due to hardware limitation of the boards interconnection.
Because of this the LCD may not get initialized (stays blank) following a cold start (power on) of the board even if the demo was
correctly programmed to the FLASH memory. In such a case simply press the reset button to restart the demo.
