LIN J2602 Example

salmanshaikh — Wed, 30 May 2018 07:40:30 GMT

Hi, I am using LIN Stack 'FSL_LIN_2.x_STACK_Package_4.5.9' with MC9S12XEP100 micro for implementing a master node for LIN J2602 networks. In examples present in stack, there is no example on J2602 example.

If anyone has worked on J2602, Could you please share a reference example?

FSL_LIN_2.x_STACK_Package_4.5.9 for xwp100 only includes XEP100_Gateway and 9S12XEP100_slave_node.

For xep100, please refer S12VR32_example.

Have a great day,
Jennie Zhang

Hi Jennie,

My concern is, there is no example for J2602 Protocol.

I checked S12VR32_example, this is also for 2.1 LIN only.

Hi,

I contacted LIN development team. I was told they will prepare a demo code for you.

I will send it to you as well as I get it.

Best Regards

Hi Salman

Attachment is an example code for implement a master node for LIN J2602.

This example run in EVB9S12EXP100 STARTER KIT REV B.

In this example I use BUS clock 2M, and the calculate of baudrate have big tolerance. It is a limitation of current code. And to work around with this we can use another bus clock or add a below code to line 1741 of file lin_lld_sci.c.

a = (tmp+1)*16*lconf_p->baud_rate - MCU_BUS_FREQ;

b = MCU_BUS_FREQ - (tmp+1)*16*lconf_p->baud_rate;

if (a<b) {

tmp=tmp+1;

}

In the example I just add these code to make baudrate of lin bus close with true baudrate(10417 bps).

Have a great day,
Jennie Zhang
