17.4.8 CANopen handler
Example OD tables and CANopen configuration structure:
// List of fixed, read-only Object Dictionary (OD) entries
// Expedited SDO only, length=1/2/4 bytes
const CAN_ODCONSTENTRY myConstOD [] = {
// index subindex length value
};
// List of variable OD entries
// Expedited SDO with length=1/2/4 bytes
// Segmented SDO application-handled with length and value_pointer don't care
const CAN_ODENTRY myOD [] = {
// index subindex access_type|length value_pointer
};
// CANopen configuration structure
const CAN_CANOPENCFG myCANopen = {
};
Example call:
// Initialize CANopen handler
(*rom)->pCAND->config_canopen((CAN_CANOPENCFG *)&myCANopen);
The CANopen handler processes the CANopen SDO messages to access the Object
Dictionary and calls the CANopen callback functions when initialized. It can either be
called by the interrupt handler automatically (isr_handled == TRUE in CANopen
initialization structure) or manually via the CANopen handler API function. If called
manually, the CANopen handler has to be called cyclically as often as needed for the
application.
In a typical CANopen application, SDO handling has the lowest priority and is done in the
foreground rather than through interrupt processing.
