2009-07-11ARM asm LCD and ATA driver functions: Don't save r12 as it is a scratch reg. ↵Jens Arnold
Saves a bit of stack and execution time. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21795 a1c6a512-1295-4272-9138-f99709370657
2009-06-17Sansa c200v2 : lcd & backlight support, using the c200v1 lcd driverRafaël Carré
The LCD driver is unified and lcd_send_command now takes 2 arguments : the command and its argument. If there is no argument, it's set to 0 and a NOP command is issued If there is more than one argument (set X/Y address), the 2nd argument is sent as a 2nd command, and a NOP command is issued after it. Benefit : c200v2 transfers the command and the argument in one 16 bits transfer Performance should not be affected since commands without argument are only used in lcd_init() and lcd_enable() lcd_send_data() now transfers whole lines (or columns) instead of single pixels yuv is disabled for c200v2 for now Some buttons can be read, including left button (bit 6 of DBOP_DIN), but for some reason they have no effect in rockbox: to be investigated git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21321 a1c6a512-1295-4272-9138-f99709370657

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20335 a1c6a512-1295-4272-9138-f99709370657
2009-03-17Fix reds and yellows (hopefully). Some targets apparently didn't properly ↵Thomas Martitz
#ifdef lcd_enable and lcd_sleep code out, so that it got partly active in the bootloader; rename the ui simulator stub fixes most reds; for the clip: move the hook code into lcd-1bit-vert.c which should fix the bootloader red. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20333 a1c6a512-1295-4272-9138-f99709370657

2009-01-18Commit battery discharge curve for c200v1 by BertrikSikken. The old one ↵Michael Giacomelli
wasn't very realistic. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19795 a1c6a512-1295-4272-9138-f99709370657
2009-01-11c200v1/e200v1: Add battery charging. This should be usable on v2 players but ↵Michael Sevakis
those should be evaluated for current, endpoint voltage and whether or not accurate battery readings may always be obtained (which determines algorithm setup and behavior). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19748 a1c6a512-1295-4272-9138-f99709370657
2008-08-05Apply FS#9195 (LCD disable for sansa c200), which puts the sansa c200 ↵Bertrik Sikken
display controller in standby when the backlight is turned off and thereby improves runtime. I measured 40 minutes improvement over a runtime of about 14h. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18198 a1c6a512-1295-4272-9138-f99709370657

2008-04-06Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now ↵Michael Sevakis
with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16981 a1c6a512-1295-4272-9138-f99709370657
2008-03-31Fixes FS#8552. On some c200s, the second parameter in setting R_Y_ADDR_AREA ↵Mark Arigo
was being interpreted as a separate command (most commonly initiating standby mode where the screen goes blank). While this may be a timing issue, some NOPs seem to fix it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16896 a1c6a512-1295-4272-9138-f99709370657
2008-03-24Consistent naming scheme the various blit functions. * Removed ↵Jens Arnold
lcd_blit_mono() for colour targets. Plugin API became incompatible, so sort, clean up & bump. * Implemented lcd_blit_mono() for M3. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16775 a1c6a512-1295-4272-9138-f99709370657

2007-10-16Improved H10 ADC driver. We now do things exactly as the OF does. This ↵Barry Wardell
includes shifting the readings by 0x14 when PLL is enabled. Battery voltages and remote/scrollpad values adjusted accordingly. We also now wait for the ADC to indicate the conversion is complete before reading the data, so hopefully we will get more reliably steady readings. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15141 a1c6a512-1295-4272-9138-f99709370657
2007-10-12PP LCD drivers: * Optimised and cleaned up PP colour LCD drivers. ↵Jens Arnold
Immeasurable speedup on iPod Color, huge speedup on small H10 (a factor of 3). Should be a bit faster on big H10 too. * Big H10 changed bitmap format, so needs reconfiguring + full rebuild. * Better register naming for the mono LCD bridge. Register names for the colour LCD bridge. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15082 a1c6a512-1295-4272-9138-f99709370657
