Hi, i just finished the first prototypes for my glcd2usb, the graphic version of the lcd2usb. And the first display type to be supported by glcd2usb is the ks0108 family. And with that the image widget is working fine and i get a screen refresh rate of >20Hz, sufficient for fluid animations ... I'll soon publish all the necessary parts. But the contrast is not software controllable. It would be quite complicated to make this part software configurable for the ks0108 as this requires to handle a negative voltage generated by the ks0108 internally. This is justr not worth the effort as most people will never change the contrast, anyway.
