Forschung

1. Software für Studenten der Informationstechnik an der Hochschule Mannheim

Am Institut exisitert eine Softwaresammlung, die speziell für Studenten der Vertiefungsrichtung "Elektronik" zusammengestellt wurde. Diese Sammlung kann auf dem Campus oder per vpn unter ftp.hfo.hs-mannheim.de bezogen werden.

Speziell für die Vorlesung HF-CAD wurde eine CD zusammengestellt, diese ist im Institut erhältlich bzw. das Iso-Image kann hier  vom FTP-Server campusweit heruntergeladen werden.

2. Vorlesungsbegleitende Programme TWOP und HT für HP50

Stand: 17.3.2000, aktualisiert 9.1.2004, aktualisiert 1.6.2004, aktualisiert 3.4.2008

Ab der Flash-Version 1.16 läuft das für den hp 48 geschriebene Programm TWOP und die Gesamtversion HF1 nun auch auf dem hp 49G, 49G+ und HP50. Die Programme rechnen auf dem hp 49G mit obiger Flash-Version aber leider um den Faktor 2 langsamer als auf dem hp 48. Der hp49G+ ist um den Faktor 4 schneller als der hp48.  Die jeweils neueste Flash-Version (Betriebssystem des hp) findet man bei www.hp.com unter "calculators".

Das Programmpaket "HF1" enthält TWOP vollständig. Die Programme  lädt man bei nachfolgenden Links durch "SHIFT + linke Maustaste" auf den lokalen Rechner:

1) für Rechner hp48:
HF1_hp48.013  als Binär-File
HT_hp48.014  als Binär-File

2) für Rechner hp49G: 
HF1_hp49G.013  als Binär-File
HT_hp49G.014  als Binär-File

3) für Rechner hp49G+, hp50
HF1_hp49Gplus.013  als Binär-File
HT_hp49Gplus.014  als Binär-File

Hinweise zur Installation der Programme finden Sie hier.
