Projects

This is a description of some of the realised projects/products:

GSM Message

Development of the Hard- & Software of a Quad Band GSM Message Device.
Up to 20 different Messages can be sent via SMS or via Voice-Call depending on hardware events.
The Voice Messages can be easily stored vie USB MMC on the internal SD-Card.


Main Tasks:

  • Complete Hard- & Software Design of the PCB
  • Design of the PC based Configuration Tool
  • Design of the USB link for the configuration Tool. No Driver Installation necessary.


  • MMI Display

    Development of the whole Hard- & Software of an MMI Display.
    With simple commands the content of the color display can be changed or animated sequences can be played. The Content is fully configurable via standard SD-Card Memory.

    Main Tasks:

  • System Design based on Altera Cyclone III FPGA
  • VHDL Integration of the display driver together with a 32bit core into the FPGA (SOC)
  • Development of the whole Player Software and SD-Card handling routines in C
  • Hardware Design
  • PCB Design


  • DC Motor Controller with Switched Power Supply

    We did the complete design and prototyping of this 55W DC Motor controller including an universal input AC Power Supply.

    Main Tasks:

  • Complete system design of the Hard- and Software
  • Design of highly integrated switched Power Supply with Universal AC Input (85-265V)
  • Design of a low cost 4Q Driver
  • Integration of full PID control of speed and position in assembler
  • Integrated Test-Concept for Mass Production
  • This product has obtained the following certifications: CE, CB, ETL, UL


  • Cardbus/PCMCIA to Serial Converter

    This project included the development of the whole Hard- & Software of an universal Cardbus/PCMCIA to Serial Converter PCB.
    This device allows to connect most PCMCIA Modems (Analog, ISDN, GPRS, 3G) to a Serial Port of an industrial control device. It supports 3.3V and 5V cards

    Main Tasks:

  • System Design based on Altera Cyclone III FPGA
  • VHDL Integration of the PCI Interface and Microcontroller into the FPGA (SOC)
  • Development of the PCMCIA/Cardbus Handling and Interfacing Software in C
  • Hardware Design
  • PCB Design


  • USB to DMX-512 converter

    Circuit Cellar This is a simple and cheap hardware that connects to the USB port of your PC and can drive any DMX512 controllable device. An article, written by Stefan Kalbermatter of this small project together with the necessary Schematics, Drivers and Delphi Source Code has been published in Circuit Cellar, The Magazine for Computer Applications, issue 170 (september 2004 issue).

    Embedded video-image analyzer

    This project included the development of the whole Hard- & Software of a low-cost embedded video-image analyzer system:

    Main Tasks:

  • System Design based on Atmel FPSLIC
  • VHDL Integration of the whole Frame-Grabbing logic into the FPGA
  • Development of the image analysis algorythms
  • Realisation of the whole AVR-software
  • PCB Design
  • Development of the MS-Windows-based configuration tool


  • Brushless Motor Control

    We did the complete design and prototyping of this 1kW 3-Phase Motor control for brushless 300V DC-Motors

    Main Tasks:

  • Complete system design
  • Design of dedicated High-Side Gate-Drivers
  • Design of highly integrated switched Power Supply with 5 outputs
  • Development of the whole Firmware
  • Integration of PID-Algorythm in assembler
  • PCB Design


  • USB devices

    We developed several custom USB Full- and Highspeed (USB2) hardware devices based
    on FTDI-, Silabs- and Cypress chips:

  • System Design
  • PCB Design
  • Firmware Development
  • Windows Driver Development
  • Development of the MS-Windows host applications


  • RF-ID Systems
    Kalbermatter
    Realisation of several developments based on 125kHz RF-ID technology

  • System Design
  • PCB Design
  • Programming of the Low-Power micro-controllers in Assembler & C
  • Development of the corresponding Test-Equipment
  • Development of the MS-Windows host application


  • Watch modules

    Development of several analog and digital watch modules for several world brands:

    Realised rasks:

  • System Design
  • PCB Design
  • Custom LCD Design
  • Programming of the 4/8 Bit Low-Power micro-controller in Assembler
  • Development of the corresponding Test-Equipment
  • Documentation
  • Typical power consumption (including LCD): < 1uA


  • LCD-Simulation

    Freely configurable real-time simulation of LC-Displays under MS-Windows. The pixel-information is gathered directly on the target-emulator and sent to the PC via USB. To simplify the installation, the USB link requires no Driver installation at all.
    This device allows the complete verification of microcontroller applications, even without having the final LC-Display ready yet.


    Realised tasks:
  • System design
  • Development of the Microcontroller Firmware
  • PCB design
  • Development of the PC-Software



  • POCSAG Decoder

    PC based Pocsag Decoder. Allows analysis, logging and message decoding of Pocsag data streams. The Error-correction level ( BCH Code(31,21) ) can be freely configured.

  • System Design
  • Development of the Parallel-Port hardware
  • Development of the PC low-level drivers in assembler
  • Development of the PC-Software



  •  
    Software for Quality Management of School Lessons and Seminars


    Development of a MS Windows-Database Software, that allows to analyse and manage the quality of school lessons and seminars.

  • Development of the data entry client used by the students
