2.124.37 USARTx_LIN_IdentifierRead Function

C

/* x = USART instance number */

/* Blocking and Ring buffer mode */

uint8_t USARTx_LIN_IdentifierRead( void)

Summary

This API allows the application to read LIN ID received during reception of LIN Header

Description

This API allows the application to read LIN ID received during reception of LIN Header

Precondition

USARTx_Initialize must have been called for the associated USART instance.

Parameters

Returns

API returns identifier read from LIN Id register

Example

/* LIN IDs */
#define READ_SWITCH_LED_PID             0x80
#define WRITE_LED_PID                   0xC1
uint8_t rxBuffer[10];

void LIN_Id_Rcvd_Callback_Handler( uintptr_t context)
{
    /* Read out the PID */
    rxBuffer[0] = USART0_LIN_IdentifierRead();
    switch(rxBuffer[0])
    {            
        case READ_SWITCH_LED_PID:
            /* Client should be in PUBLISH mode now, as client has to send SWITCH status requested by Master */              
            break;

        case WRITE_LED_PID:
            /* Client should be in SUBSCRIBE mode now, as Master is about to send data for LED ON/OFF */       
            break;
    }
        
}
/* Register a callback for LIN id received events */
USART0_LINIdCallbackRegister(LIN_Id_Rcvd_Callback_Handler, (uintptr_t)NULL);

Remarks

None
