CANopen driver for Microchip dsPICs

1 July 2015 Design Automation

Designed for target systems with or without operation systems, Port’s CANopen driver packages provide all necessary functions for initialisation of the hardware, controlling the CAN controller, message filtering and buffering, and provision of a timer period. All drivers are available as documented ANSI-C source code, allowing for quick and easy adoption to system specific hardware and trouble-free compilation.

The object dictionary produced by the CANopen Design Tool supports numerous features of Port’s CANopen library, such as several CAN lines and segmented structuring. A tree representation of all implemented parameters and data facilitates the maintenance of the device software.

It is a tool with which device databases can be produced and processed. These databases contain information which describes the interface for the CANopen network of the device. These are all parameters, control and status information that are accessible over CAN. The CANopen protocol stores these values in the so-called object dictionary of CANopen devices.

The major task of the CANopen Design Tool is to administer and create these data in an object database and to create code for the CANopen library from it. Furthermore the tool is used to configure the CANopen driver packages. Within one project several hardware configurations can be managed, allowing for quick changes between different targets during development.
