2003-02-16 Mark Riley <markril@users.sourceforge.net>
* Improvements to high memory Patch 638513
* Improved motor handler to allow full speed operation. Previously,
every 256ms the outputs would float for 1ms when setting the motor
speed to maximum: motor_a_speed(MAX_SPEED)
* Moved motor handler to high memory
2003-02-13 Stephen M Moraco <stephmo@users.sourceforge.net>
* Applied Patches. For more detail on each, see the closed
patches still on file at the brickOS sourceforge project web
* Applied Patch 638513: Make use of high memory (Mech. only)
(the patch moved mm routines to high mem. This is not
yet decided, so no routines are moved, yet.)
* Applied Patch 651692: Add setjmp/longjmp (ANSI C support)
* Applied Patch 668115: Make brickOS work with up-to-date binutils
* Applied Patch 673995: Patch brickos 0.2.6.09 for *BSD
* Fixed bug 666378: Motors still running when RCX turned off
(applied fix described in bug report at site.)
2003-01-11 Ed Manlove <emanlove@users.sourceforge.net>
* Modified makedepend to $(MAKEDEPEND) in lib/*/Makefiles
2002-12-13 Joseph A Woolley <jawoolley@users.sourceforge.net>
* Update system time so that motor controller is called every 1ms
as in previous version
2002-11-07 Stephen M Moraco <stephmo@users.sourceforge.net>
* Adjusted configure to prevent false detect of directory as compiler
2002-10-22 Stephen M Moraco <stephmo@users.sourceforge.net>
* Converted Makefile.common and rest of makefiles to
support the new ./configure utility
* Use of ./configure is now required
2002-10-16 Stephen M Moraco <stephmo@users.sourceforge.net>
* Move Makefile.kernel into boot/Makefile (was only consumer)
* Finish install targets, add uninstall target
* Generate & install installed forms of included and demo
makefiles (generate by filtering existing then installing)
2002-10-15 Stephen M Moraco <stephmo@users.sourceforge.net>
* 2nd pass at cleaning up Makefiles
- added build/install of all docs as targets separate
from normal brickOS build/install
- enabled 'make tag' from top Makefile
* Install of headers and brickOS itself is all that remains
to be done in next make update
* Merge util/Makefile.common into top Makefile.common
- rework util/ Makefiles to use top Makefile.common
2002-10-11 Joseph A Woolley <jawoolley@users.sourceforge.net>
* Added locked_increment and locked_decrement to inc/dec an
unsigned char value; interrupt safe. Added
locked_check_and_increment function; used by
enter_critical_section.
* Added critsec.c, critsec.h and sys/critsec.h to implement
critical sections.
* Added a 'kernel critical section' that can be used in the
kernel to keep the task swapper from switching tasks.
This is a simple and 'cost effective' way to manage critical
resources. This prevents a task from being killed while
in a critical region of code. It also keeps two tasks
from modifying kernel structures at the same time. This
replaces the use of semaphores which don't support nesting
and cannot be used while in the task manager while swapping.
A task should never yield, sleep or exit while in a critical
section; whether kernel or user level.
* Replaced semaphore in task manager with critical section.
* Replaced semaphore in memory manager with critical section.
* Added definitions for the Control Status Register (CSR) for
the Watch Dog Timer (WDT) and the Counter Register (CNT)
for the WDT.
* Seperated sys_time increment code from the systime_handler
and attached sys_time clock to the WDT. This is
configured to use the NMI, so clock should be more
accurate. Named sys_time handler 'clock_handler'.
* Seperated sub-systems from task switcher in systime.c
and called sub-system handler 'subsystem_handler'. The
sub-system handler will call the task switcher handler
* Named the task switcher handler 'task_switch_handler'.
* Attached task switcher handler to OCA of the 16 bit timer
and subsystem handler to OCB of the 16 bit timer. The OCA
and OCB interrupts can be configured at different intervals,
however, they are linked. The timer will reset on A, so
B will be delayed until A is reached, then the timer is
reset and B can be reached again. B must be less than A
or B will never be reached. Currenty, A and B alternate
every msec.
* Adjusted the lnp_timeout_counter, auto_shutoff_counter,
vis_refresh_counter and lcd_refresh_counter; (cut in half)
since the subsystem_handler is only called once every two
msecs.
* The task switcher is checked every msec since direct
modification of the timeslice counter can be used to tweak
task wake-up. msleep currently does this to allow wakeup
to interrupt lower priority tasks mid-slice.
* Removed another static buffer used by LNP. Instead, I
Added code to malloc and free the memory as needed. Added
#ifdef blocks to resort back to static buffers if CONF_MM
is not defined.
2002-10-11 Stephen M Moraco <stephmo@users.sourceforge.net>
* First pass at cleaning up Makefiles by normalizing
subdirectory handling, and adding install targets.
* There are a couple more Makefiles to update before thie
is done.
2002-09-25 Stephen M Moraco <stephmo@users.sourceforge.net>
* Awakened API doc for Kernel Developers
* Added Demo pages to each API set
* Upgraded control files to New Doxygen Version
2002-09-23 Joseph A Woolley <jawoolley@users.sourceforge.net>
* Removed static buffer in program.c that is used to copy
lnp packets. Instead, malloc and free buffer as needed.
2002-09-22 Stephen M Moraco <stephmo@users.sourceforge.net>
* NEW add LEGO Lamp support for C++
* NEW added demo/c++/lampTest.C as example
* 2nd wave of API documentation updates
2002-09-20 Joseph A Woolley <jawoolley@users.sourceforge.net>
* Added support for "safe-shutdown" of tasks. Updated tm, mm,
program, semaphore and a few others. Updated demos.
* Look in demo programs for examples of new code usage.
2002-09-04 Stephen M Moraco <stephmo@users.sourceforge.net>
* First wave of internal comment updates for Doxygen
extraction of API documentation
This round included (1) upgrade of Doxygen control files
(2) revision of file brief descriptions, and (3) excluding
of __asm__ code blocks from the generated HTML API docs.
2002-09-01 Stephen M Moraco <stephmo@users.sourceforge.net>
* Remove legOS from Makefiles and doxygen files
* Add Linux/Debian support to Makefile.common
* Prep as 1st brickos test release
2002-08-28 Joseph Woolley <jawoolley@users.sourceforge.net>
* Updated comments, code and data structures to refer to
tasks instead of threads and processes.
* Added menu choice for modifying LNP Host Address at
run-time.
* Added menu choice to delete current program.
* Added low priority task to animate man (while program
running) and to show/hide the battery low indicator.
* Updated execi and tm_switcher to keep a tally of the
number of kernel tasks at run-time. This value is
used to determine if any user tasks are running.
* Updated comments from LegOS to BrickOS and from LegOS
Network Protocol to Link Network Protocol (unofficial)
* Fixed minor bug in mm_try_join for "end-of-memory"
condition. Previously unchecked, the pointer would
wrap around into kernel memory; producing undefined
behaviour.
* Updated killall so only user tasks or all tasks are
killed.
* Added T_IDLE flag to indicate which task is the idle
task. Removed now-unnecessary idle_task global
variable.
* Modified tm_sleep_wakeup so tasks will interupt lower
priority tasks when wakeup time is between time-slices.
2002-08-21 Stephen M Moraco <stephmo@users.sourceforge.net>
* Changes to loader utils to support new internal name
* Changes to .lx image to contain brickos vs. legos
* Makefile changes to generate brickos files vs. legos
2002-08-21 Ted Hess <thess@users.sourceforge.net>
* Allow setting LNP Host address at build or load-time
- Specify LNP_HOSTADDR=n on make command-line (0 .. N)
- Use dll option --node={hostaddress} or -n{hostaddress}
Note: CONF_LNP_HOSTADDR in config.h is now a small integer
instead of shifted mask
* fix LEGOS_ROOT macro to work in sub-directory (makefile)
* added $CDEFINES macro for compile-time defines (makefile)
* minor fixes for various config option combinations to build properly
* added CMDsethost to dll protocol to set host addrs
* use Win32 device name for USB tower on Win32
* updated man page for new dll options
2002-05-05 Stephen M Moraco <stephmo@users.sourceforge.net>
* Applied Patch #552135: RCX Remote control support + misc
fixes: animated figure (doesn't fidget anymore),
dll Program numbers now consistent (1 - 8), LCD display
of motor dir during braking now correct, cputc_native_xxx macros
now allow expression as arg, and dll now allows delete of program.
* small adjustments to two demos
* This effectively removes the prior IR Remote implementation as
it is now a blend of the two patched approaches
* Added new config settings:
CONF_RCX_PROTOCOL // RCX protocol handler (lnp)
CONF_LR_HANDLER // Remote control button event dispatcher
CONF_RCX_MESSAGE // Standard firmare message functions
Which replaced the following settings:
CONF_REMOTE_CTRL // remote control
CONF_RKEY_HANDLER // remote control keys handler
CONF_RKEY_MOTOR // remote control motor
CONF_MESSAGE // standard firmware message
2002-04-28 Stephen M Moraco <stephmo@users.sourceforge.net>
* Added Motor control to complete implementation of
Patch #475185: Remote Control & Standard Message Patch
* Cleaned up Makefile.user targets (much more to do)
