Draw
This Draw sample ADL Library provides to ADL applications APIs to draw and move sprites on a graphical LCD. The used SPI LCD in this sample is the Samsung KS 0719.

Application Description

This application provides a game, running with LCD and keyboards interfaces.

As this application uses the MultiApp library, the following start/stop command has to be used to control the application execution.

AT+GAMESTART (LCD Game start/stop command)

Command	Answers
AT+GAMESTART?	+GAMESTART: <state> OK
AT+GAMESTART=?	+GAMESTART: (0-1) OK
AT+GAMESTART= <state>	+CME ERROR: 3 or OK

Parameter	Values range	Description	Default value
state	0-1	The current application running state. This parameter is stored in non-volatile memory.	0

The init entry point sent to the MultiApp library is the gam_init() function. The start/stop entry points linked to the +GAMESTART command are the gam_Start() and gam_Stop() functions.

This application is a "Hardball" game using the keyboard and LCD interfaces.

The defined keys are :

0 : go left.
4 : go right.
2 : select -> to start or resume the game.

When all bricks are destroyed, or whan the ball fall on the ground, the score is displayed, and the game can restart with the "select" key.
