brickOS-bibo contributors
=================

V1.0.0
---------

Jochen Hoenicke (hoenicke@users.sourceforge.net)
  bibo core designer


Matthew Sheets (mesheets@users.sourceforge.net)
  Bug Fix: dkey_wait() and getchar() calls in user programs would lock the brick
  Added support for using the system buttons (On-Off, Run) in user programs
  Merged patches for BrickOS with Bibo,
    including LDCC, lnp_printf, and lnpmsg (formerly LegOShrink)
  Host Utilities
    - Updated utils to better facilitate using TCP as a tty.
    - Enable default tty names for types TCP and USB
      ~ TCP defaults to localhost:50637
      ~ USB defaults to /dev/usb/legousbtower0
    - Made NCD tty types a runtime option instead of a compile-time #define.
    - Reworked firmdl3, dll, and lnpmsg under utils as well as
        lnp and lnp-logic in the kernel to facilitate better code reuse,
        remove essentially duplicate code, and establish a set of common
        functions for rcx_comm and LNP.  Merged the resulting code into
        util/host, deprecating util/firmld, util/dll-src, and util/fontdesign.c.
    - Util dll: made fast mode a runtime option instead of a compile-time #define.
  Host Communication
    - Added ability to send LNP messages directly from the lnpmsg command line.
    - Added ir-server from Jochen Hoenicke's BrickEmu package and used
        the code reworked from above to add support for tty downlinking
        (e.g. serial, USB, TCP) or TCP uplinking.
  Communication
    - Changed baud rate, carrier state, and timeout settings from compile-time
        defines to run-time options
    - Standardized parity for all baud rates to "odd"
    - Added support for RCX-based communication that does not echo (e.g. bluetooth hacks)
    - Enabled more flexible communication options for downloading firmware
  Refactored direct motor code
    - Added support motor variables (instead of motor-specific functions)
    - Added support for retrieving current speed and direction values
    - Added support for reversing motor direction without needing to know current direction.
  Configure
    - Refactor to suppor for a common CFLAGS
    - Update search paths
  Refactor "makelx" to "writelx" so that the makelx name can be repurposed
  Make and Makefiles
    - Remove duplications across Makefiles to simplify
    - Update "make install" to better support DESTDIR
    - Provide consistent path configuration for both source tree and installation
    - Enable configurable kernel naming
    - Create a "version series" (first digit of the version number) for include files
      ~ Includes for legacy brickOS 0.9.0 are "v0"
      ~ Includes for this version are "v1"
    - Enable "multi-kernel" support for working among kernels of differing configurations
      ~ Is backwards compatible with having the legacy brickOS 0.9.0 kernel installed
        as a kernel within the multi-kernel structure
    - Enable building/installing/uninstalling just specific parts,
        such as lib, kernel, rom, or lib+kernel+demos ("rcx").
    - Minimize the hardcoding of absolute paths in the Makefile that gets installed
    - For the Makefile for *.lx programs, verify that the needed kernel files exist
    - Create a "makelx" script that can be used to build programs without
        needing to know how Make or Makefiles work
    - Eliminate some of the manual updates needed when adding/removing shared libraries
        or when switching between using static linking in the kernel
    - Support building programs written in Esterel and XS:Lisp
  Programming Languages
    - Merged XS:Lisp (based on BrickOS 0.2.6.10) with Bibo.
      ~ Added support for additional conio functions to XS
    - Added support for building Esterel programs if the Esterel compiler is installed
  Various updates and refactors to reduce firmware size, including:
    - Updated code so that CONF_ASCII can be disabled by default, including:
      ~ Modified conio to remove the CONF_ASCII dependency from CONF_PROGRAM
    - Adding a CONF_EXTENDED_MUSIC configuration so that the pitch2freq array
        is only included if absolutely needed, such as for scenarios like
        transposing note_t arrays or reducing combined kernel+program size if
        the number of note_t element in programs exceed ~100
    - Adding a CONF_PRINTF configuration so that *printf() and similar capabilities
        (e.g. itoa()) are only included if needed
    - Separated out *printf() and similar capabilities (e.g. itoa()) from libc
        into a separate libprintf library
  Sound and Music (in addition to CONF_EXTENDED_MUSIC above)
    - Expanded musical scale note defines
    - Added defines for the individual note frequencies
    - Added tempo calculation support for sound/music
  Added the open source ROM implementation from Jochen Hoenicke's BrickEmu package
  Various code cleanups...

bibo is heavily based on brickOS, written by Markus L. Noga.  The following
lists the other contributers of brickOS.  I did not check, whether their
contribution is still present in bibo.
