I am messing around with TFT displays now and have been interested in my TFT displays bitmap function, however, it is very slow. when doing any other kind of colour printing/messages it is about as instantaneous as I"d expect, but when doing bitmaps it takes almost 30seconds to fully update the 320x480px screen.

I"m wondering if this is normal for this type of display and setup and if not then, how can I speed it up! Ideally I"d like to display simple animations!
