Return Values:
Pointer to the next node in the list (NULL if at list end).
This function is called to get the address of the next message in the list. Typically, this is used in
conjunction with MessageGetHead() to traverse the message list. First MessageGetHead is called to
get the pointer to the head of the list. Then MessageGetNext is called in a loop to get the next node
based upon the last one returned by either MessageGetNext or MessageGetHead. When
MessageGetNext() returns a NULL, the end of the list is reached.
void msgInitialize (void)
Initializes the Message Manager.
This should be called before any calls to the Message Manager component are made. Otherwise, the
internal data structures are not initialized, and their values are not guaranteed.
void msgRelease (uint8_t msgNo)
Releases a managed message.
Parameters:
msgNo
Indicates which managed message to perform the operation on
This function is called to release one of the managed messages.
5.0.3 MAC LAYER MANAGER API
Detailed Description:
The MAC Manager (layer) is responsible for sending and receiving packets using the PHY. The MAC
Manager is analogous to the MAC layer in the OSI standard 7-layer stack. It provides the ability to
send messages to addressed nodes and to optionally receive acknowledgements for those
messages. If an acknowledgement is expected and not received, the MAC layer will retry the
message.
Data Structures:
struct TMACMsgObject
Defines the internal properties of a TMACMsg. union TMACMsg.
Defines a MAC-layer message.
Typedefs:
typedef uint32_t TMACAddress
Defines the MAC-layer address type.
Enumerations:
enum TMACPacketType { kMACUniAck = 0, kMACUniNoAck = 1, kMACMulti = 2, kMACACK =
3 }
Defines the MAC-layer message types.
