com_dict.h File Reference

Detailed Description

The file com_dicts.c implements the local object dictionary of the CANopen Master protocol stack. The local object dictionary is an array of ComDicEntry_ts elements. By means of ComDictAddList() an object dictionary can be assigned to a logical CANopen network during run-time.

An example for a local object dictionary is given by the file com_dict_master.c inside the template-com directory.

Typedef Documentation

ComDicEntry_ts

typedef struct ComDicEntry_s ComDicEntry_ts

CANopen Master - local object dictionary entry.

The structure ComDicEntry_s describes a single dictionary entry. Each entry is defined by the index, sub-index, access-attribute and data type. The pointer pfnFunction points to a callback function.

Function Documentation

ComDictAddList()

ComStatus_tv ComDictAddList	(	uint8_t	ubNetV,
		ComDicEntry_ts *	ptsDictListV )

Parameters

[in]	ubNetV	CANopen Network channel
[in]	ptsDictListV	Pointer to dictionary structure

Returns

Value of enumeration ComErr_e

This function adds an local object dictionary structure to the CANopen network channel defined by ubNetV. If a NULL pointer is passed to ptsDictListV the local object dictionary supports only the objects 1000h, 1001h and 1018h by means of an internal object dictionary structure.
