Itead 4.3" not working due to large code size.

My sincere greetings to all the hobbiest and DIY-enthusiast,

After being recently know to the flexibility and power of the Arduino, I have come up with a project to use Arduino with 4.3" touch screen as an interface for controlling Steam in the Steam Bath. After doing some trail and error and developing the interface for almost 6 months, i am finally stuck at the last step,
Here is what is bothering me :
As soon as the size of the sketch reaches more than 40 %, the LCD stops functioning. This increase in size is caused due to having multiple bitmaps in the sketch.

Kindly advice me how can i overcome this.

Rishi Soni.

Put your bitmaps on an SD card.... Then use UTFT_SdRaw :wink: (Shameless plug for my library!! :P)

Graham
