How S12ZVML64 realizes LIN communication

[mine233]

I debugged the motor program through S12ZVML64, but it can only be debugged through freemaster. But I want to control through LIN communication. How can I integrate LIN communication into the motor program.

Hello @mine233,

The S12Z LIN Stack is avaiable at the S12ZVM webpage:

You can refer to AN5122 Using Freescale’s LIN Driver with the MagniV Family:

https://www.nxp.com/docs/en/application-note/AN5122.pdf

AN5122SW:

List of MagniV and S12(X) Application notes:

Hello,

FreeMASTER  supports different communication interfaces - you do not describe which of them you use, so I assume you use the serial communication (SCI/UART) which is a default option. 

In order to use the LIN protocol, you will need to integrate a LIN software stack into your application. A LIN stack is available from NXP. I will ask my colleagues to help you find it.

BTW: Note that FreeMASTER can also communicate over LIN, but there are several limitations and pre-conditions. The FreeMASTER requires the LIN stack to support "diagnostic class II & III" which is not very common. In short, when you start using LIN, you will most probably lose the FreeMASTER connectivity (or you can run it over another SCI port).
