I used this example
https://community.nxp.com/t5/MPC5xxx-Knowledge-Base/Example-MPC5604B-LINFlex-LIN-Master-Slave-commun...
I want to use LIN interrupts, is there an example I can refer to?
and during the example test
-----------------------------------------------------------------
static void LIN0_ReceiveData(uint16_t bidr_value)
{
/* Master to receive x bytes with ID and CCS from bidr_value */
LINFLEX_0.BIDR.R = bidr_value;
/* Trigger Frame transmission */
LINFLEX_0.LINCR2.B.HTRQ = 1;
/* wait until Slave response to the LIN header has been receive successfully */
while(0 == LINFLEX_0.LINSR.B.DRF)
{
/* track LIN Status for errors */
// stop here
}
/* read BDR registers */
rx_data[0] = LINFLEX_0.BDRL.B.DATA0;
rx_data[1] = LINFLEX_0.BDRL.B.DATA1;
rx_data[2] = LINFLEX_0.BDRL.B.DATA2;
rx_data[3] = LINFLEX_0.BDRL.B.DATA3;
rx_data[4] = LINFLEX_0.BDRM.B.DATA4;
rx_data[5] = LINFLEX_0.BDRM.B.DATA5;
rx_data[6] = LINFLEX_0.BDRM.B.DATA6;
rx_data[7] = LINFLEX_0.BDRM.B.DATA7;
/* clear RMB, HRF, DRF and DTF flags */
LINFLEX_0.LINSR.R = 0x0207;
}
------------------------------------------------------------
When data is received it works fine, but when no data is received it stops at the while statement. Is there any way to solve this?
please help thank you
