Loewe Machine Environment & Applications / News: Recent posts

SimpleOS 1.3 has been released.
SimpleOS is a base layer for applications written
for the Loewe Machine. It has been designed and
implemented during a course about embedded
systems at the FHDW, Hanover.

This release has been rewritten with multi-threading
in mind. Threads and semaphores for
synchronization are now supported. A simple
round-robin-scheduler completes the
multi-threading part of SimpleOS.

HardwareSimulator 0.61 has been released. The
hardware simulator interprets programs written for
the Loewe Machine and is the environment within
which the applications can be built, loaded,
executed, and debugged.

This release fixes a bug in the previous release and
adds some new features. See the ChangeLog for
details.

Ergometer 1.2 has been released.
Ergometer is a simple application for a hypothetical
embedded device (an ergometer). The underlying
system layer can either be LOEMOS or SimpleOS.
See the file requirements.txt in the package to
determine which versions of the system layers are
supported.

This release is now capable of handling the On/Off
button in the hardware simulator correctly by (re-)
initialising all internal state at each hardware boot.
Furthermore, two bugs were fixed. See ChangeLog
for details.

This release is now capable of handling the On/Off
button in the hardware simulator correctly by (re-)

LOEMOS 0.15 has been released.
LOEMOS is an attempt to provide a simple but
effective operating system for the Loewe Machine.

This release improves interrupt handling and
introduces new inline procedures.

LOEMOS 0.14 has been released.
LOEMOS is an attempt to provide a simple but
effective operating system for the Loewe Machine.
This release fixes a possible portability problem in
the previous release. It requires at least
HardwareSimulator 0.6.

LOEMOS 0.13 has been released.
LOEMOS is an attempt to provide a simple but
effective operating system for the Loewe Machine.
This release requires at least HardwareSimulator
0.6 because of the use of inline procedures. Driver
initialization has been simplified. Furthermore,
LOEMOS has been prepared to be assembled and
executed on a 32-bit Loewe Machine which may
become reality in the future.

Ergometer 1.2 will be released soon. Among other
features, Ergometer 1.2 will be capable of handling
the On/Off button in the hardware simulator
correctly by (re-)initialising all internal state at each
hardware boot.

Ergometer 1.1 has been released.
Ergometer is a simple application for a hypothetical
embedded device (an ergometer). The underlying
system layer can either be LOEMOS (at least
version 0.11 is required) or SimpleOS (at least
version 1.1 is required).
This release adds a time display with two modes,
displaying the remaining and the elapsed training
time.

SimpleOS 1.1 has been released.
SimpleOS is a base layer for applications written
for the Loewe Machine. It has been designed and
implemented during a course about embedded
systems at the FHDW, Hanover.
This release adds the stack machine operations
SSHL and SSHR.

LOEMOS 0.12 has been released.
LOEMOS is an attempt to provide a simple but
effective operating system for the Loewe Machine.
This release's improvements are not functional; the
code has been commented at some more places.

LOEMOS 0.11 has been released.
LOEMOS is an attempt to provide a simple but effective operating system for the Loewe Machine.
This release fixes some bugs as well as adds
some new stack machine operations.
