S32K344 LIN ONLY SEND HEADER

JAY_SUN1 · ‎10-03-2022

Hi Sir,

We develop S32K344 with RTD2.0.0 now, but we meet some problem for LIN. We would like to send header only by UartLin but we don't find suitable Funtion. Please help to check it and let us know the solution. Thanks.

Hi,

if referring to, for example, Lin_Ip_FrameTransfer_S32K344 example, below function is used to send frame

Second parameter of Lpuart_Lin_Ip_PduType_structure contains info about LIN frame, in example

A Drc specifies response type, which can be

First is master sends heder+data, second master sends header and wait for data from slave and the last one master sends header and ignores response from slave.

So use 2nd or 3rd response type, as per your needs.

BR, Petr
