Detailed Description

Functions for accessing object dictionary of this device by other devices.

SDO client related functions. They are used for accessing a slave modules object dictionary

Warning:

No functions are implemented yet, because SDO transfer hasn't been implemented yet. Feel free to implement it ;-) (you can more or less copy the needed source from CanFestival at http://canfestival.sourceforge.net - thanks to Edouard Tisserant)

Function Documentation

void loadOD (  BYTE    bSubindex )

A remote node can call this function (by SDO) to load the standard Object dictionary (OD) from a persistent memore (EEProm, Flash, ...). This is useful, if the OD has been modified, but you want to undo this changes. the argument indicates which subindex is called (different subindicies stands for different load-options. see standard)

void processReceivedSDO (  s_rx_buffer_message *    canopenMessage )

this function is called by proccessRxCanMessages. it is responsible for proccessing SDO messages. e.g. if the server wants to read/write an entry in the Object dictionary Parameters: canopenMessage  Contains the CAN-Message that has been received by this device.

void saveOD (  BYTE    bSubindex )

A remote node can call this function (by SDO) to save the state of the Object dictionary into a persistend memory (EEProm, Flash, ...). the argument indicates which subindex is called (different subindicies stands for different save-options. see standard)
