Project: June 2015 – July 2015 (2 months)

Description

Planning and creating of the firmware for a CAN repeater (quasi-repeater) as a plug replacement for sensor data acquisition in tunnel construction machines. CAN messages are converted to UART to transmit them via an air gap using a FSK modem. To supply the sensors in the drill head, the coupler provides 500mA of current.

Description

The PCBUSB library realizes a ‘PCAN-USB Driver for macOS’ using Apple´s IOUSBKit. It supports up to 8 PCAN-USB and PCAN-USB FD devices from PEAK-System Technik, Darmstadt. The library offers an easy to use API to read received CAN messages from a 64K message queue and to transmit CAN messages. The PCAN-USB FD device can be operated in CAN Classic and CAN FD mode. Standard CAN frames (11-bit identifier) as well as extended CAN frames (29-bit identifier) are supported.
The library comes with an Objective-C wrapper and a demo application: MacCAN Monitor App.

Project: 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.

Project: January 2009 – February 2009 (2 months)

Description

Firmware expansion for compact drives to include client-specific functions. Based on pre-existing driver firmware, the backlash is compensated by the software method ‘Pilger Rolling/Looping’ in order to achieve higher positioning precision. Using this method, all positions are addressed only from one direction. This means that the target positon is always addressed from one direction while, in the opposing direction, the target position will be skipped by a value larger than the backlash and then addressed afterwards.

Description

Working with the specification and development of a controller board with MPC5200B (Freescale) and real-time Linux (Kernel 2.6 RT Preemptive, PTXdist). The project provides a shared HW platform and a generic SW framework for product-specific central controller of generator systems for plasma excitation, induction heating, and CO2 laser excitation.
My main activity in the project was focused on the definition and realization of the SystemCAN for the communication of generator modules. SystemCAN is based on the CANopen protocol according to CiA DS-301 (EN 50325-4).
During the project, the customer introduced a model-based development approach according to UML 2.0 and established an agile development process according to OpenUP.
