MC9S12ZVC transmission error

I set MC9S12ZVC as a slave. The signals and frames from the master product come from my MCU, but I can't send them from MCU to the master. What should I do to make a slave in my product line?

Hello,

Please specify the interface, is it SPI, I2C, LIN?

Thank you,

Hello @jhChoi ,

You need to call l_u8_wr_ macros to write the data that you can get in lin_cfg.h file according to your LDF.

I have attached LIN User Manual. Check page no 53 you will get the sample program it might help for you.

The same document you can get in your location C:\NXP\LIN_stack_S12_4_6_3\Documentation if you installed LIN stack.
