LIN Driver using UART[0] for S32K311NHT0MLFST

kiran5 — Fri, 16 May 2025 06:55:25 GMT

I am using S32K311NHT0MLFST for my project.

I am trying to configure the UART[0] as a LIN driver. Is there any example code available for the particular controller or a controller from the same family.

FIFO option is supported for this particular controller. So it would be very helpful if i can get some example on how the FIFO will be configured.

Thanks

Kiran

Hi Kiran,

We don't have RTD LIN examples for all the S32K3xx derivatives.

This is RTD 5.0.0:

But there are LIN Stack examples for S32K311 too, they use the driver.

The driver does not use the FIFO.

It would increase the complexity of the driver.

Daniel

HI Daniel

Thanks for the Stack information.

Need some more support regarding Baudrate.

Does this controller support auto baud rate feature for LIN2.0 specification?

Thanks

Kiran

Hi @kiran5,

Yes, the LIN driver support Auto baudrate regardless of the LPUART instance.

Refer to S32K3_S32M27x LIN_43_LPUART_FLEXIO User Manual that is available in the installation directory of the RTD driver

Section 3.6.5 Auto-detect baudrate feature.

Daniel
