Project: July 2002 – September 2002 (3 months)
Description
Development of a CAN / CANopen master software library for Infineon C16x microcontrollers with the following features:
- Initialization of the on-chip CAN Controller (82527-compatible):
- Baud rates: 10kBit/s to 1MBit/s (according to CiA bit-timing table)
- SDO Protocol (segmented und expedited, according to CiA DS-301, version 4.0):
- Easy to use access to 8-bit, 16-bit und 32-bit objects (CiA encoding rules)
- Adjustable time-out monitoring (on time-out an SDO abort message will be sent)
- Detailed error feedback (communication errors or SDO abort codes)
- NMT-Broadcast (Network Management according to CiA DS-301, version 4.0)
- LSS Services (Layer Settings Services according to CiA DSP-305, version 1.0)
- LMT Services (Layer Management Services according to CiA DS-205, part 1 & 2)
- Event Queue for event-driven message processing, e.g. for:
- Receive-PDOs (RxPDOs)
- Emergency-Messages
- Heartbeat-Messages
- Access to CAN Layer 2:
- Transmit Message (e.g. for TxPDOs, SYNC-Object, TIME-Object)
- Request Message (e.g. for RTR-PDOs, Node-Guarding)
The package is characterized by low usage of microcontroller resources. The software library is also available for Infineon XC16x (TwinCan) and Mitsubishi M16C (Renesas) microcontrollers.
Support of other microcontrollers on request.
