Overview

This GUI demo is developed with the Embedded Wizard GUI solution.

The intention of this example is to demonstrate the graphics performance. For this purpose, a set of basic drawing operations are executed permanently and continuously: As a result, an endless stream of drawing instructions is produced... In case that the graphics hardware provides a graphics accelerator, it can be switched on/off to demonstrate the advantage of a graphics accelerator. The user can choose the current graphics operation and switch on/off the usage of the graphics acclerator (if available).

The resulting framerate (in fps) and the resulting CPU load (in percent) will be shown.

This examples runs bare metal, but Embedded Wizard is also possible to use with FreeRTOS. Our official Build Environments, that can be downloaded as described above, includes examples and demos that illustrate the integration of FreeRTOS and can be used for your reference.

In order create your own GUI application powered by the latest version of Embedded Wizard that is suitable for the i.MX RT1050 Evaluation Kit, please visit https://doc.embedded-wizard.de/getting-started-mimxrt1050-evk

For this example a simulation of the user interface is also available. It can be used under following link http://www.embedded-wizard.de/NXP-SDK-Examples/IMXRT1050-EVK/GraphicsAccelerator/Simulation/ with any web browser. The simulation uses the JS/WebGL Embedded Wizard Platform Package. For further information about Embedded Wizard, please visit our web site at https://www.embedded-wizard.de/platforms/nxp/imx-rt

SDK version

• Version: 2.15.000

Toolchain supported

• IAR embedded Workbench 9.40.1
• GCC ARM Embedded 12.2
• Keil MDK 5.38.1
• MCUXpresso 11.8.0

Hardware requirements

• Micro USB cable
• IMXRT1050-EVKB board
• RK043FN02H-CT or RK043FN66HS-CT6 LCD board
• Personal Computer

Board settings

1. Connect the RK043FN02H-CT or RK043FN66HS-CT6 to board.

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. Build the project, the project uses RK043FN66HS-CT6 by default, to use other panels, change #define DEMO_PANEL DEMO_PANEL_RK043FN66HS to #define DEMO_PANEL DEMO_PANEL_RK043FN02H in ew_bsp_touch.h
4. Download the program to the target board.
5. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

If this example runs correctly, the sample application is displayed on the LCD screen. The log below shows the output of the sample application 'GraphicsAccelerator' in the terminal window:
