changed HD44780 to use generic bar functions
|
|
finished bar.c, USBLCD is the first driver that uses the generic bar functions
|
|
introduced bar.c, moved bar stuff from display.h to bar.h
|
|
USBLCD fixes
|
|
implemented the new ndelay(nanoseconds) in all parallel port drivers
|
|
GPO bug: INIT is _not_ inverted
|
|
fixed compile HD44780.c, cosmetics
|
|
some fixes to ppdef
off-by-one bug in processor.c fixed
|
|
minor cleanups
|
|
make ppdev compatible to earlier kernels
|
|
added ppdev parallel port access
|
|
new udelay() using Time Stamp Counters
|
|
reworked autoconf a lot: drivers may be excluded, #define's went to config.h
|
|
first (incomplete) GPO implementation
|
|
HD_gpo() was missing
|
|
prepared framework for GPO's (general purpose outputs)
|
|
corrected a bug in HD_goto()
Thanks to Gregor Szaktilla <gregor@szaktilla.de>
|
|
new debugging scheme: error(), info(), debug()
uses syslog if in daemon mode
|
|
opened 0.98 development
removed driver-specific signal-handlers
added 'quit'-function to driver structure
added global signal-handler
|
|
some changes to support kernel-2.4 (different layout of various files in /proc)
|
|
eliminated some compiler warnings with glibc
|
|
moved delay loops to udelay.c
renamed -d (debugging) switch to -v (verbose)
new switch -d to calibrate delay loop
'Delay' entry for HD44780 back again
delay loops will not calibrate automatically, because this will fail with hich CPU load
|
|
added '-d' (debugging) switch
added several debugging messages
removed config entry 'Delay' for HD44780 driver
delay loop for HD44780 will be calibrated automatically
|
|
added BogoMips() to system.c (not used by now, maybe sometimes we can
calibrate our delay loop with this value)
added delay loop to HD44780 driver. It seems to be quite fast now. Hopefully
no compiler will optimize away the delay loop!

|
first version of the HD44780 driver
