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
