If you look at the code, you'll notice this app builds off the previous pointInRect tutorial post.
TouchShield code,
COLOR BLACK = {0,0,0};
COLOR RED = {255,0,0};
COLOR BLUE = {0,0,255};
COLOR WHITE = { 255,255,255};
unsigned char x,y,state;
POINT p;
void setup()
{
state = ON;
ledControl(state);
drawButton(state);
}
LCD_RECT buttonRect = {10,100,40,120};
void loop()
{
if (touch_get_cursor(&p))
{
if (pointInRect(p,buttonRect))
{
if (state==ON)
{
state = OFF;
ledControl(state);
drawButton(state);
}
else
{
state = ON;
ledControl(state);
drawButton(state);
}
}
}
}
void drawButton(unsigned char state)
{
lcd_rect(buttonRect, BLUE, BLACK);
if (state == ON)
{
lcd_puts("On", 20, 108,BLUE,BLACK);
}
else
{
lcd_puts("Off", 20, 108,BLUE,BLACK);
}
}
void ledControl(unsigned char state)
{
COLOR ledColor = {0,0,0};
if (state == ON)
{
ledColor.red = 255;
}
for(x=1;x<4;x++) y="1;y<4;y++)">
