* lcd drivers: Convert lcd_[remote_]framebuffer to a pointerJonathan Gordon2012-02-28
| | | | | | | | | | Change all lcd drivers to using a pointer to the static framebuffer instead of directly accessing the static array. This will let us later do fun things like dynamic framebuffer sizes (RaaA) or ability to use different buffers for different layers (dynamic skin backdrops!)

* Increaase default ipod 3g contrast, to a value between the last two.Torne Wuff2010-05-20
| | | | | | | | | It seems there is some significant variance between different greyscale ipods of the same model, so it's unlikely that *any* value will be great for everyone. I'm hoping that this is just high enough that the lightest screens aren't totally blank, but not dark enough that the darkest screens are entirely unreadably black ;) This rather unsatisfactory compromise is to help us get a new bootloader release out (since bootloaders can't have their contrast adjusted) - a real fix would be to detect the LCD type, which the OF appears to be able to do (maybe). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26208 a1c6a512-1295-4272-9138-f99709370657

* Greyscale library: Optionally put the greyscale ISR on COP on ↵Jens Arnold2008-04-04
| | | | | | portalplayertargets (only use with the grey_info structure in IRAM atm\!). This speeds up doom by ~50%, and makes mpegplayer work without stuttering audio on targets using it (measured on iPod 2nd Gen and Mini 2nd Gen). It needs corelocking certain functions in the LCD driver on 1st/2nd Gen. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16973 a1c6a512-1295-4272-9138-f99709370657
* 1st/2nd Gen: Backlight inversion needs to be protected from interrupts, ↵Jens Arnold2008-04-04
| | | | | | because it can happen any time, even while the greyscale lib or something else is writing to the LCD from an ISR. Also make backlight inversion only hit the LCD if necessary. * Use register definition in the 1st..3rd Gen backlight drivers. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16962 a1c6a512-1295-4272-9138-f99709370657
* LCD driver tweaks for greyscale iPods: * Use 1/7 bias, 5x step-up and the ↵Jens Arnold2008-04-02
| | | | | | highest step-up frequency on all 1st..3rd gen iPods, simplifying the driver this way. The default contrast for those iPods has changed - reset settings in case the display becomes unreadable. * Set n-line inversion drive to 9 lines, improving image quality on 1st..3rd gen iPods somewhat. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16932 a1c6a512-1295-4272-9138-f99709370657

* Greyscale library: Changed the internal data format once more (separated ↵Jens Arnold2008-01-09
| | | | | | pixel values and phases), allowing for further optimisation of drawing, scrolling etc. * Optimised grey phase blitting in the core reduces CPU load on all architectures, most significantly on coldfire. Previous version was too slow to keep up at 45MHz, leading to unwanted graininess (update frequency was halved). Also fixed screendump on 2bpp targets with vertical pixel packing. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16043 a1c6a512-1295-4272-9138-f99709370657
* All-new greyscale library, replacing the old one. Features: (1) ↵Jens Arnold2008-01-04
| | | | | | Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15998 a1c6a512-1295-4272-9138-f99709370657
