API Functions
LIN_Init()
20
The message status is stored in the table called LinMsgStatus[]. When the LIN
driver is initialized all messages will get the status LIN_MSG_NODATA.
Message status will change when the message is being sent, received, or
updated.
Table 5
message is received at a node.
Table 6
sent from a node.
This function initializes the LIN driver and makes the driver ready to detect LIN
communication. Initialization of the driver includes:
LIN_Init() must be called before any other LIN API function is called. It takes no
parameters and returns nothing.
Usage example:
LIN_MSG_NODATA
LIN_MSG_OK
LIN_MSG_NOCHANGE
LIN_MSG_UPDATED
LIN_MSG_OVERRUN
LIN_MSG_UPDATED
LIN_MSG_OVERRUN
LIN_MSG_OK
LIN_MSG_NOCHANGE
LIN_MSG_NODATA
