Stm32(cortex m3) project: Touchscreen click & drag scrolling with microcontroller Stm32

This is a continue of "beatstream project". I've update firmware implementing library to create fully customizable window (size and position window, color bar, header, background,object select,font) with touchscreen scroll. You can scroll up and down to select your item. The effect is similar to Iphone or android mobile (obviously not the same! XD ). The entire project works without O.S..Contact me for info or comment ( always welcome ).
