PR-043: Software for Double Clutch Transmission

April 2022 - December 2023 (21 months)

Description

The existing project at the customer consists of the actual functional software and a library for the safety level (functional safety according to ISO 26262-6). The safety library is being further developed due to change requests from the OEM as well as new legal requirements regarding safety requirements (ASIL D). The control software as a whole supports two different ECUs from different manufacturers and is used by the OEM in five different transmission derivatives. Within the scope of the software development, an ASPICE level 2 is to be achieved.

Support of the FuSa team in Berlin and Gifhorn with the following main activities:

  • Change request driven coding according to Fastlane process
  • SYS.2 Requirements analysis/creation/adaptation and review of work results
  • SWE.1 Requirements analysis/creation/adaptation and review of work results
  • SWE.2 Software architecture creation/adaptation and review of work results

PR-042: C Development for a Jib Crane

January 2022 - March 2022 (3 months)

Description

Due to the worldwide shortage of microprocessors in the context of the COVID-19 pandemic and possible future discontinuations of the microprocessors in use, the customer is revising its product range. The existing control electronic for pillar- and wall-mounted slewing jibs is ported to a new microcontroller (for which second source types are also available) without reworking the application program itself. The drivers of the Hardware Abstraction Layer (HAL) are newly developed and connected to the existing application program via wrappers.

My task in the project was the development of the drivers and wrappers for ADC, I2C, UART, as well as their commissioning on the (new) target hardware.

PR-030: Hardware Oriented Software Development

December 2010 - December 2011 (13 months)

Description

Support of several development teams at the client's site. My tasks included:

  • Development of hardware oriented software applications
  • Creation of hardware oriented drivers
  • Implementation of real-time operating systems on embedded platforms
  • Customization of BIOS and driver software
  • Project support from requirement engineering to validation

Work Batch 1: Analogue CAN Transmitter for Force Feedback Sidestick Control

The transmitter is used to transmit analogue and digital signals from a redundant sidestick control via the CAN bus. Through two physically connected sidesticks in the cockpit, the steering system, as well as the gas and brake systems, are controlled. From these systems, current angle data is transmitted back to the systems in the cockpit.

Task: Implementation of the transmitter software (CAN bus).

Work Batch 2: End-Of-Line Test Software for a Control Panel for Floor-borne Vehicles

The vehicles are optionally equipped with a Truck Data Unit (TDU). At the beginning of vehicle use, the driver identifies himself by means of an identification assigned to him (optionally via a keyboard with a PIN number or by means of a card reader with RFID identification) and thus indicates the use of the vehicle. When leaving the vehicle, the driver logs off.

Task: Implementation of the test software on the target for end-of-line testing of analog and digital I/O modules, memory devices (F-RAM, NAND-Flash, Data-Flash), LEDs, CAN-communication, matrix keyboard, wake-up function, card reader (RFID), Bluetooth module.

Work Batch 3: Compressed Download via CANopen

Control panel for blacktop paver with display and CAN interface. A CANopen bootloader handles software updates.

Task: Integration of the zlib inflate algorithm into existing boot loader.

Work Batch 4: SPI Bootloader for HVAC Front Panel

Front panel for climate control intended for a DIN radio slot. Control and display unit with integrated color display, illuminated buttons, and control dials. Communication with the main circuit board takes place via an SPI data bus system and controls all button and encoder inputs, as well as visualization of the display.

Tasks: a.) Implementation of the bootloader (SPI slave). b.) Implementation of test procedures.

PR-019: CANopen Master API

October 2005 - December 2005 (3 months)

Description

Implementation of a CANopen Master API (Application Programming Interface) as a 32-bit Dynamic Link Library for Windows. The software library supports various CAN interface boards from different manufacturers:

  • IXXAT Virtual CAN interface
  • PEAK PCAN-Light Interface
  • M + K RS-CAN converter (ASPopen)
  • Support of additional interface boards on request

The package includes two simple PC-based sample programs: A monitor program (CANmonitor), which cyclically reads the event queue of the CAN interface board and displays the received CAN messages on the screen. In addition, an object browser (COPbrowser), which allows access to the object directory of individual CANopen devices. The browser can be used for parameterization and simple device diagnostics.
