The application simulates the behavior of the system in a 24 hour period considering an

hour as equal to 20 seconds. After 24 hours (simulated), it resets the array values, so the

GraphCharts and the histograms show a maximum value set to zero.

vGraphicLibraryTask

Table 12 describes the vGraphicLibraryTask task:

This function checks if an input device has been stimulated (touchscreen or joystick/button)

and calls the graphic library relative function according to the object pressed.

Example:

static void vGraphicLibraryTask( void *pvParameters )

{

/* Menu Initialization*/

MENU_DeInit();

CursorShow(195, 50);

/* Infinite main loop ------------------------------------------------------*/

while (1)

{

ProcessTouchScreenData();

/*Time out calculate for power saving mode*/

TimeOutCalculate();

#ifdef USE_STM3210C_EVAL

if (restart_calibration==1)

{

TS_Calibration();

restart_calibration = 0;

MENU_DeInit();

}

CursorReadJoystick(IOEXP_MODE);

TSC_Read();

#else
