Thomas Martitz dc07c79263 Sansa AMS: Time has shown that switching between 16 and 32bit mode costs much time (due to the micro delay needed), so do 32bit transfers unconditionally for lcd updates at the cost of updating slightly larger rectangles (gives upto 15% speed up, nearly at maximum now).
Unify this optimized dbop transfer function and re-use it more often (it still handles 16bit transfers).

backlight-target.h e200v2: implement the backlight handling (copy/paste from the c200v1/e200v1 code - this should probably be unified, along with other upcoming v2 code), plus clean up the lcd init by calling lcd_init() directly in the bootloader, instead of lcd_init_device(). 2008-10-29 01:42:03 +00:00
button-target.h Fix FS#10128 - The View IO Ports debug menu showed weird dbop values (sometimes FFFF prepended), due to sign-extension. Switch to unsigned short to fix it. 2009-04-20 20:11:01 +00:00
