emu51 under GNU/Linux

ASM Software was able to build and run the 8051 emulator emu51 (http://emu51.sourceforge.net/) under GNU/Linux.

Download the source distribution, make sure you have the Allegro library installed, and now compile emu51 with this Makefile.

The emulator seems to work but keep in mind it is very early alpha and the interface not that easy.

If you use SDCC, make sure to issue the packihx command first. emu51 has problems with reading the .ihx output of SDCC properly.

Once a port to the SDL library was planned but the project was abandoned due to lack of time.

Tools and files for 8051 compatible microcontrollers

Here you can find some tools, configuration files and generic information regarding MCS51 compatible mcus.

as31 assembler for Intel 8051 derivates

This is a patched version of the famous as31 assembler. It is now compatible with our development board. And can therefor be used with other Phytec 8051 boards and units as well. The original of the assembler can be found at Paul’s 8051 tools.

Quadromania

Introduction

Quadromania is a board game. Your task is to restore the originating board filled with red stones. The computer will pick a named amount of 3×3 tile sets and will flip the colours of the selected tiles.

This means a red tile will become green, a green one the next colour in the amount of colours, red again in the simplest case. You select the amount of colours to use and the amount of initial rotations.

In the running game click on the center point of a 3×3 tile set to exchange that selected set following the rules above. Restore the board full of red stones before you reach the limit of maximum turns.

Quadromania is a work in progress. I currently lack the time to do a decent development on it. However the current alpha release is somewhat playable and working.

Requirements

  • GNU C Compiler (preferrably 3.2 but works with older ones as well)
  • GNU Make
  • SDL
  • SDL_image

You can find SDL and SDL_image at the SDL website.

The current release adds support for autoconf and automake.

Downloads

NOTICE: This is currently alpha software. Do not expect everything to work. It may crash or even do not compile!
Each archive contains a file called INSTALL. This contains installation instructions.

Gopher Test Project

This is our Gopher Test Project. It concludes my research concerning this vintage hypertext protocol. It included the development of an experimental server.

Experimental Gopher server in bash

This is our first implementation of the Gopher protocol. It is written in Bash. It needs some tweaking. It should be run from inetd. No more instructions provided – see the code for details.

KDE Support Center

ASM Software offers you some simple components to enhance your KDE desktop. They include servicemenus to improve some handlings from the Konqueror filemanager and some icons for your use.

Archive icon set


A small set of icons you can use and associate with various packer formats like ZIP, ARJ, RAR, ACE, 7z and LZH.

Extract 7z servicemenu

A simple service menu for Konqueror that enables you to unpack 7z archives with a single click.
To install this service menu, simply copy the .desktop file to ~/.kde/share/apps/konqueror/servicemenues/ and restart Konqueror.

Mount ISO image as virtual CDROM

This little servicemenu allows you to mount and unmount ISO images as a virtual CDROM via the loopback device of your Linux kernel.
The commands will prompt you for your root password.
To install this service menu, simply copy the .desktop file to ~/.kde/share/apps/konqueror/servicemenues/ and restart Konqueror. Additionally you have to create the required mount point for the virtual CDROM as root. The default pathname is /media/isoimage but you can change it in the desktop entry file with any texteditor.

mit Linux (S)VCDs erstellen

Das ist garnicht mal schwierig! Natürlicherweise sollte man ungefähr die doppelte Menge an Festplattenplatz bereitstellen, die die Videodaten schon einnehmen, einmal um das Format anzupassen, und einmal, um ein CD Image zu speichern, welches man dann brennen kann.

Für den Anfang sollte man das Material, von dem man (S)VCDs erstellen möchte, abspielbereit auf der Platte liegen haben. Eigentlich muss man nur die folgenden Schritte durchführen:

  1. Filme in das (S)VCD Format konvertieren
  2. ein CD Image erstellen, bei dem die einzelnen Filme dann als (S)VCD Spuren erscheinen
  3. die CD brennen
  4. ausprobieren (Xine, Kaffeine oder Mplayer sollten alle funktionieren)

Konvertiert werden die Daten am einfachsten mit FFMpeg. Das Eingangsformat darf dann MPEG, DivX oder so ziemlich alles sein, was FFMpeg versteht. Natürlich hat es Probleme mit WMV Files mit DRM Schutz, aber da wir hier ja von der Aufbereitung privater Clips sprechen, etwa aus einer Digitalkamera, sollte uns das nicht weiter stören ;)

Um ein Video nach (S)VCD zu konvertieren, startet man ffmpeg wie folgt in der Shell:

ffmpeg -i <Videodatei> -target pal-vcd <Ausgabedatei.mpg>

Hat man das für alle Dateien erledigt, dann kann man daraus ein CD Image erstellen. Das Programm vcdimager erledigt das mit folgendem Aufruf:

vcdimager -c <cuedatei> -b <bindatei> <Mpegfiles>

Wichtig dabei ist, das die Mpegs alle im SVCD kompatibelen Format vorliegen, so wie mit ffmpeg oben konvertiert.

Am Ende haben wir dann eine klassische .bin/.cue Kombination, die man mit k3b oder dgl. brennen kann.

Zumindest bei Ubuntu LTS sind nötigen Tools als Pakete vorhanden und müssen nicht erst kompiliert werden.

Viel Spaß mit euren neuen SVCDs, die dann auch in den allermeisten DVD Playern abspielbar sind!

Distupgrade

Tzz, statt wie geplant mit Doxygen zu basteln bin ich grad dabei im Labor ein Dist-Upgrade zu fahren. Alles nur, weilUbuntu von Breezy Badger nicht mal mehr Paketarchive hat. Keine Updates ist ja eine Sache, aber gleich die Pakete komplett löschen? Das war bei Debian besser gelöst…also nur um Doxygen zu installieren, rödelt jetzt die Kiste. Mag ich eigentlich nicht. Ich geb ja zu, Lust zum Arbeiten hab ich keine, aber so will ich ja auch nicht die Produktivität erniedrigen.

Morgen dann mal sehen…
