The Bibo Patch Rollup Collection posted to SourceForge at
http://sourceforge.net/tracker/?func=detail&aid=2773502&group_id=58151&atid=486699
has been updated.
New for this update are patches 25 through 35.
25: Cleanup in the util subdirectory
- Updated lnpmsg to more cleanly handle and process command-line arguments
- Removed in mkimg that is a duplicate of code in srecload
- Updated some Makefile cross targets
26: Updated makefiles
- Changed the existing TOOLPREFIX to CROSSTOOLPREFIX, then used TOOLPREFIX
for the host tools (needed when creating packages that must be targeted to,
for example, a 486 processor)
- Moved some target definitions to Makefile.user, since it is shared by
both Makefile.dist and Bibo's make process. This also reduced Makefile
dependencies across SUBDIRS (util, lib, include, kernel, demo, doc). Some
individual subdirs can now be removed from the SUBDIRS assignment statement
in the main Makefile and the rest of the project will still build
successfully.
- Updates related to util/host, as it seems to be stabilizing. Some items
in util/Makefile.sub have been moved to util/host/Makefile.sub, since the
code now resides there
- Removed the need to set PROGRAMS when building *.lx files. Building %.c
/ %.cpp / %.s / %.S will now look for a make variable by the name of "%_SRC"
to determine if additional object files need to be built.
- Changed the cross-compiler optimization from -O2 to -Os (space)
27: Configuration #defines
- Added a CONF_VIEW_BUTTON define based on Taiichi Yuasa's modification,
allowing exclusion of the information display normally provided when
pressing the RCX View button. The primary reason for adding this
configuration define is enable building a smaller kernel.
- Added a configuration define needed in one of the demo programs in case
CONF_RCX_MESSAGE is not defined.
28: Merged XS Lisp - http://www.xslisp.com/
- A few of the above patches were in preparation for this update
- Was originally based on BrickOS 0.2.6.10
- Is not an addition to the kernel but instead can be used to build *.lx
files that can be downloaded to the RCX. The generated *.lx programs are
large, so a smaller kernel is needed.
- Supports both an IR-link mode and an autonomous mode (IR features were
updated to use rcx_comm)
- Added better support for building from Makefiles
- For the full detail on XS, please see the file xs/README and or visit
the website. Note that information on the website refers to files such as
xs, xs0, xs1, xs2, etc. When merged with Bibo, the numeric suffixes were
replace with more descriptive text, and xs/README reflects this
modification.
- A list of suggested configurations to disable is also included in
xs/README. Any other recommendations or suggestions here would be
appreciated.
29: RCX Communication
- Created a tty struct to replace the existing FILEDESCR and tty_type_t
that get passed around in host-based programs.
- Replaced the fast/slow options in the host utilities with support for
specifying a baud rate at run-time.
30: RCX Communication Timeout for Host Utilities
- Timeout value in milliseconds can now be specified at run-time instead
of being a build-time #define. This is useful when switching between a
low-latency, local IR tower and a TCP connection over the Internet (e.g.
using the uplink and downlink features added to ir-server) with a higher
latency.
31: TTY Device Names
- Added support for interpreting NQC-style port name strings of the format
"<device type>:<device name>". This format was already being used by the
TCP and NQC Bibo additions and was extended to include "serial:" and "usb:".
Backwards compatibility with existing conventions has been maintained.
32: Read Default TTY from a Config File
- Added support for reading the default tty device name from a
configuration file ("~/.rcx/tty.conf"). This essentially fulfills the same
purpose as the RCXTTY environment variable, but without some of the
limitations of environment variables. I am hoping to be able to add this
support to NQC, too.
33: IR Communication and Hacked-on (e.g. Bluetooth) Communication
- Attempted to provide an easier starting point for those using
communication hacks such as the bluetooth hack
~ Ability to set the baud rate
~ Ability to turn of echo handling
- Created configuration #defines to allow setting defaults for
~ Baud rate
~ IR Carrier enabled/disabled
~ Transmit echo/no echo
- Replaced slow/fast (2400/4800 bps) options with the ability to select a
baud rate
- Firmware downloads at 2400 bps can now also be completed without sending
the complement bytes (previously, this option was only available for "fast"
4800 baud)
- Enabled setting the communication timeout value at run-time. This is
useful, for example, when switching between a low-latency serial connection
and a higher-latency TCP-based connection.
- Improved the keepalive functionality for serial IR towers
- Moved help text for standard rcx_comm options to the rcx_comm header
file
** IMPORTANT CHANGE NOTE: Parity for all baud rates is now "odd"
34: Config File Cleanup
- Removed #define entries for configurations that no longer exist
- Removed RCX-only #define entries from the host configuration file
35: Remove CONF_ASCII Dependencies
- Currently, if CONF_PROGRAM is defined CONF_ASCII must also be defined.
This patch reduces the CONF_PROGRAM dependency level from CONF_ASCII to
CONF_CONIO, reducing the size of the kernel needed for program support.
- Created #defines for each of the entries in CONF_ASCII's
ASCII-to-CONIO-mask lookup table
- With those #defines, CONF_ASCII is no longer needed for displaying
static strings. (The small hex lookup table included by CONF_CONIO is still
present there.) Functions that are variants of cputc_native*, cpuc_hex*, or
cputw may be used to write to the display. For example, cputs("Lego") may
now be written as cputc_native_user(CHAR_L, CHAR_e, CHAR_g, CHAR_o). While
it's a little longer statement to type, it does help toward reducing kernel
size. ;-)
- All demo programs were able updated to eliminate the need for
CONF_ASCII.
- For dynamically generated strings, CONF_ASCII will still be required.
XS utilizes CONF_ASCII features for the XS functions that mirror the cputs
andcputc C functions (puts and putc), but due to the large size of XS, this
patch just limits the cputs/cputc functionality if CONF_ASCII is disabled
(puts will output "ASCII" and putc will display a '-' in the specified
position).
Thanks,
Matthew

The Bibo Patch Rollup Collection posted to SourceForge at
http://sourceforge.net/tracker/?func=detail&aid=2773502&group_id=58151&atid=486699
has been updated.
New for this update are patches 36 through 39.
36: RCX tty config file - Extends patch 32 so that /etc/rcx/device.conf will
also be checked for a default tty. The precedence order is first, the
RCXTTY environment variable; second, ~/.rcx/device.conf; third,
/etc/rcx/device.conf.
37: Automatic Shutoff Timer - Reset the automatic shutoff timer if the Lego
remote is used in direct mode (when no programs are running).
38: Firmware Fastloader - Added code to initialize the IR carrier frequency.
39: Linux Patches - As some of you may already know, I have been using
Cygwin. I am currently working to get a Linux-based BrickOS/Bibo
environment up and running, and though that Linux environment is not yet
fully functional, this patch is needed to help some of the earlier patches
run under Linux.
A word of thanks goes to Dr. Jochen Hoenicke for his assistance in answering
questions; any errors are mine. :-)

The Bibo Patch Rollup Collection posted to SourceForge at
http://sourceforge.net/tracker/?func=detail&aid=2773502&group_id=58151&atid=486699
has been updated.
There is just one minor Bibo-specific update this time, patch 40.
40: H8/300 TOOLPREFIX - This patch comes from Debian, where
"h8300-hitachi-coff-" is added to the list of potential H8/300 toolprefixes.
The larger update this time is a set of patches for NQC running on Linux.
Included in these patches is a patch that corresponds with Bibo patches 32
and 36, which enables Bibo to read a default tty device name from a
configuration file. This same capability has now been extended to NQC.
More details on the NQC patches are available here -

The Bibo Patch Rollup Collection posted to SourceForge at
http://sourceforge.net/tracker/?func=detail&aid=2773502&group_id=58151&atid=486699
has been updated.
New for this update are patches 41 and 42.
41: Makefiles and the Esterel Synchronous Programming Language - The
makefiles were updated to support building Esterel source files for the RCX.
More information and links to the Esterel software required for building is
available at http://www.emn.fr/x-info/lego/. Five sample/demo programs
listed on this site have been included in an "esterel" folder in the bibo
distribution (make will only attempt to build these programs if the Esterel
compiler is found).
Also, when doing a "make && make install" on the bibo source, the installed
makefile may be used to build program source files by running "make -f
/path/to/installed/makefile SOURCES=demo.strl" (or demo.c, demo.cpp, demo.s,
demo.S); alternatively, you may run "make -f /path/to/installed/makefile
PROGRAMS=demo.lx" and make will attempt to build the corresponding code
file.
NOTE: While Esterel supports the CPUTS command, this requires that ASCII
support be enabled in Bibo. ASCII support is now disabled by default due to
(1) the size required for its support and (2) the fact that CONIO was
updated to make it easier to output characters to the display without the
size bloat of ASCII support. Some Esterel-generated programs can be quite
large, so space can be at a particular premium when using Esterel. Ideally,
Esterel could be updated to support some of the CONIO functions.
42: RCX Comm - Updated debug output. Modified rcx_init to allow specifying
whether or not to start the IR tower Keepalive handler (this setting does
not have any effect if the device does not require Keepalive functionality).
Thanks,
Matthew

The Bibo Patch Rollup Collection posted to SourceForge at
http://sourceforge.net/tracker/?func=detail&aid=2773502&group_id=58151&atid=486699
has been updated.
New for this update are patches 43 and 44
43: Per the report from SourceForge user bollinge, Cygwin no longer has a
problem building printf.c. A Cygwin-specific conditional in
lib/c/Makefile.sub was removed.
44: Kernel size optimization - The values for BASE1 and BASE2 have been
declared as constants; however, calculating these values dynamically enables
greater ease of flexibility in handling changes to the kernel image size.
This is change is based on SourceForge tracker 1120793, but this
implementation is different from what was proposed in that tracker and does
not add a dependency on Perl like that tracker implementation would. This
particular update closes the last currently outstanding patch (apart from
the "(Unofficial) Bibo Release" patch) listed in SourceForge, though I still
have note of a few various and sundry updates posted elsewhere.
Thanks,
Matthew

Excellent, Matthew. Many thanks for keeping the project alive and moving
forward.
I've uploaded a little patch with the edge counting (which I needed once
upon a time when I tried to build a plotter without any rotation sensors)
re-implemented in a more sensible way. Here:
https://sourceforge.net/tracker/?func=detail&aid=3527703&group_id=58151&atid=486699
I'm currently working on figuring out all the little quirks of the power
functions protocol (such as what happens with the toggle bit state for
commands where the toggle bit is ignored). Once I have it fully working,
I'll release a patch with power functions control based on Bob Kojima's
code but updated to match the latest PF specification.
Cheers,
//Carl
