Detailed Description

Simulation.

Message replication between multiple CAN CoreX instances.

Enumeration Type Documentation

CCX_net_node_type_t

enum CCX_net_node_type_t

Network node types.

Defines whether a node's transmitted messages propagate to the network.

Note

Example:

• NODE_IN_NET: Node A transmits → message reaches Node B, C, D
• NODE_REPEATER: Node A transmits → message stays local, but Node A still repeats messages from B, C, D to its physical bus

CCX_net_replication_t

enum CCX_net_replication_t

Message replication modes for network nodes.

Defines how messages from other nodes in the network are handled.

Note

Example: Node A sends message → Node B receives it:

• TX_REPLICATION: Message appears only in Node B's TX buffer (forwarded to bus)
• TX_RX_REPLICATION: Message appears in both TX and RX buffers (forwarded + processed)

Function Documentation

CCX_net_clear_nodes()

CCX_net_status_t CCX_net_clear_nodes

(

CCX_net_t *

net

)

Clear all nodes from a network.

Resets all node entries to NULL with default settings:

• NodeInstance: NULL
• Replication: CCX_NET_TX_REPLICATION
• NodeType: CCX_NET_NODE_IN_NET

Parameters

net	Pointer to network to clear

Returns

CCX_NET_OK on success

CCX_NET_NULL if net is NULL

Note

This does NOT remove the network from the global list (use CCX_net_deinit for that)

CCX_net_deinit()

CCX_net_status_t CCX_net_deinit

(

CCX_net_t *

net

)

Remove a CAN network from global list.

Removes the network from the global linked list. Does not affect node instances.

Parameters

net	Pointer to network to remove

Returns

CCX_NET_OK on success

CCX_NET_NULL if net is NULL

CCX_NET_DOES_NOT_EXISTING if network not found in list

CCX_net_init()

CCX_net_status_t CCX_net_init

(

CCX_net_t *

net

)

Initialize a CAN network.

Adds the network to the global network list. Networks are managed as a linked list to support multiple independent networks.

Parameters

net	Pointer to network structure to initialize

Returns

CCX_NET_OK on success

CCX_NET_NULL if net is NULL

CCX_NET_ALREDY_EXISTING if network already in list

Note

Network node list is NOT cleared - call CCX_net_clear_nodes() first if needed
