LIN on S32k344

rishabh_10 — Tue, 06 Aug 2024 12:40:47 GMT

Hello,

I am working S32k344 LIN, and I am not able to receive or send frame. I have configured the project as below:-

1.) LPUART1 (PTC8, PTC9)

2.) Enable PTB19

3.) PTB18 high for commander & low for slave.

Let me know why this issue is occurring and how can I solve it, forward me a good understandable example of master and slave separately if you can or make changes in the original file which I am attaching to this mail.

Looking forward to hear from you soon, as I need this on priority.

Thanks,

Rishabh

Hi,

if looking for Matlab/Simulink/MBDT implementation please post your question rather at https://community.nxp.com/t5/Model-Based-Design-Toolbox-MBDT/bd-p/mbdt

Otherwise there are two RTD demos you can refer to, where LPUART is used as LIN Master/Slave
- "Lin_Ip_FrameTransfer_S32K344"... simple application which shows a communication between a Lin Master and a Lin Slave of both Lpuart Ip and Flexio Ip
- "Lin_Master_S32K344_Example_DS" and "Lin_Slave_S32K344_Example_DS" ... LINStack example demonstrating the LIN communication between S32K344 Slave and other board Master using unconditional frames.

BR, Petr
