V2.2  (Sep'99, TB+KS)
- bug fix for OSReschedule in preemptive mode (return to main of no thread)

- elimination of clib from RoBIOS

V2.1  (Sep'99, TB)
- enabled preemptive multitasking
- added camera support for EyeCam CMOS camera
- added functions LCDPutInt, LCDPutHex

V2.0
- added functions for Radio communication
- fixed VWStalled
- adapted to new MK3 board design

V1.9
- not published

V1.8
- OSPutVar() and OSGetVar() are changed again. They use the TPU-emulation RAM instead of the TPU-PRAM.
  Now 10 reset resident variables are available (SAVEVAR0 - SAVEVAR9). Six of them are used by now.
- The Robot-ID is reset-resident now
- new linux makefile
- 100Hz TimerIRQ cleaned up
- Sounddemo is more 'intelligent' now in occupying memory for recording
 
V1.7
- new entries in 'hdt_sem.h'
- names changed from lines and rows to rows and columns
- headerfiles protected against multiple inclusion
- OSPutVar() and OSGetVar() are removed from the user-library because the 'Output Compare'
  TPU-function needs 2 of the 4 used reset resident TPURAM locations and the remaining
  2 locations are used by ROBIOS allready.
- new submenu Hrd/Set/Rmt to change the Robot-ID (temporarily) and the RemoteControl state (reset-resident)
- Robot-ID is displayed in the main menu
- Fresh up of the serial driver:
  buffersizes changed to 128 bytes each
  RTS/CTS is now only used if the user wishes to
  in the case of a bufferoverrun the receiver stops until all buffered chars are read or flushed
  OSCheckIn/Out are changed to report errors (and restart the receiver afterwards, CheckIn)
- all TPU channels are initialised to zero level at startup

V1.6b
- new HDT for biped walker
- caseinsensitive acceptance of 'STARTUP.HEX' for autostart programs added
- fixed bug in vwstalled()
- moved system heap to the heap-area of a userprogram, therefore no heap is available
  for Robios if there is no userprogram loaded (malloc is not longer allowed within Robios)
- multitasking demo removed from Robios (it has used malloc, which is since V1.6b
  forbidden to use within Robios)

V1.6
- bug in VWDriveWait() fixed (OSSleep instead of OSWait in noneMT mode)
- HDT semantic definitions sperated into new file hdt_sem.h 
  added new semantics (servos)
- new HDT for revision 'E' Eyebot-vehicles
- new function VWStalled implemented (virtual bumper)
- new function OSMachineID implemented (unique number for each platform)
- implemented an autostart of an userprogram with the name 'startup.hex' after a reset.
  If there are several 'startup.hex' programs in ROM, the one with the lowest slotnumber
  is started. To avoid this mechanism of starting up a program, any key has to be pressed
  while reseting.  

V1.4c
- fixed severe waitstate bug, ALL waitstates out of the HDT have been set incorrect
  this led to a enormous slowdown of the system (i.e. 10fps instead of 16fps in camdemo)

V1.4b
- new download cmd for unix (by T. Braeunl)
- cosmetic fresh up for multitasking (by T. Lampart)
  - mtmode indicates now also an inactive multitasking (value 255)
  - all MT functions terminate with an errormessage if they are called in singletasking mode
  - all semaphore functions return the actual countervalue
- new PSD semantics defined in hdt.h (by T. Braeunl)
- VWWait() modified to deal with single- AND multitasking
- new OS function OSMTStatus() which returns the actual multitasking mode
- bug in VWDriveCurve() fixed by Birgit Graf (fabs instead of abs)

V1.4a
- bugfix for servo-driver
- readable errormessages included (by Thomas Lampart)
- new function OSMachineName which returns the actual name of the Eyebot (published in HDT)
- new cmd-files to compile hdt-files, no makefiles any longer (by T. Braeunl)
- PSD-driver modified to guarantee a correct measurement directly after a PSDRelease / PSDInit 
  combination  
- speed up of IP_Color2Grey(...)
- freshup of ALL image-processing functions (2 borderpixels omitted, top and borderline cleared)
- The Quickcamdriver is modified to blank all unused pixels (for ip-functions)
- CAMGetColFrame changed to enable 'on the fly' conversion into greyscale images (memory reduction!)
- Camerademo works again (stackspace for local variables was too small)

V1.4 (done by Klaus Schmitt)
- After downloading a user program the real size of the program (without bss-segment) is displayed
  with the programname. This info is saved into the datasegment of each user-program, therefore ALL 
  userprograms have to be recompiled with the new crt0.o to run properly under RoBioS 1.4!!!!
  This info is used to guarantee that only programs smaller than 128KB are saved into the Flashdrive!
- The RoBiOS and HDT are now also serial downloadable and are flashed internally!!!
  Simply download them as normal programs. RoBiOS recognizes them automatically.
  This new type of flashing supports both flashsizes (1 and 4 MBit).
- new function OSMachineSpeed(void) to obtain actual cpu clockrate
- new gcc/gas command files
- The cpu-clockrate is now selectable in 1MHz steps from 16 to 41MHz
  All timing critical sections are changed to cope with the new speeds.
  (sound, ad-conversion, serial-transmission, motors, servos, PSD...)
- To deal with higher busspeeds all waitstates are now freely adjustable in the HDT
- keyboard timing slowed down(cpuspeed adapted!), download-cancel is only tested once per 10 srecords  
- added entry in HDT to assign a unique name to each Eyebot, displayed in the main-menue
- the HDT entry for the motor and the servos are changed from cryptic timervalues to
  readable frequency(motor) and time(servo) values.
- minor bugfixes

V1.3b (packaged by Klaus Schmitt):
- new linux-makefiles, fix for empty HDTs
- preemptive MT implemented by Thomas L.
- added support for 115200 baud transmission via SERIAL2 and SERIAL3
- added support for both serial interfaces of the 16C552 (SERIAL2, SERIAL3)
  (all 3 ports can be used parallel and with different speeds/handshakes)
- added versionnumber to HDT, displayed in Hardware-Menu
- added highlevel drive commands (Straight, Curve, Turn...)
- added Timer-IRQ suport for user-programs, demo in /demos/mini
- added PI-controller to the vw-interface 
- Flashrom waitstates changed from 4 to 3 ws
- maximum adress space expanded from 512KB to 1024KB by assigning CS6 to ADDR19
  (now 1MB RAM can be addressed)
- RoBiOS splitted into 2 parts: USER and SOURCE
  The USER part is all you need to work with RoBiOS and write 
  programs for it.
  The SOURCE part is an extension of the USER part which contains
  all the sources needed to modify RoBiOS itself.
  (Copy the SOUCE part in the same diretory as the USER part!)
- all 'include'-directorys are merged and moved to toplevel 
- the HDT parameters are completely documented now (see HDT file)

  - a 'flashdrive' is added to the User-Menu to store up to three userprogramms and
    reload them easily
- the graph-library is included in the LCD-functions (LCDLine, LCDArea)
- added new hardware test functions for AD, Digital-IN, Digital-OUT, Parallel-In/Out
- CPU-speed, FLASHROMsize, RAMsize and actual Battery-status
  (HDT-switchable) is displayed in welcome-screen 
- new exit behaviour of USER-programs:
  LCD-contents is preserved, prog-runtime is displayed and
  a KEY has to be pressed to finally leave with a clear LCD  
- serious bug in USER-menue fixed (crash after aborted receive
  and attempt to start this nonexisting program)
