Overview

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

The sample application 'BrickGame' implements a classic "paddle and ball" game. In the game, a couple of brick rows are arranged in the upper part of the screen. A ball travels across the screen, bouncing off the top and side walls of the screen. When a brick is hit, the ball bounces away and the brick is destroyed. The player loses a turn when the ball touches the bottom of the screen. To prevent this from happening, the player has a movable paddle to bounce the ball upward, keeping it in play.

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 LPCXpresso55S69 Evaluation Kit, please visit https://doc.embedded-wizard.de/getting-started-lpcxpresso55s69

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/LPCXpresso55S69/BrickGame/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/lpc55S69
