Hi,

 

I'm tying to read LIN data in a K20 Family device.

 

The Final device should be a data logger for logging of LIN data and serial data to Write this data to SD card

 

My system hardware setting:

 

Uart 1 - LIN data from test device  - rx line connected LIN Bus with 10k resistor.

Uart 3 - serial data from test device

Spi connection to Micro SD Card Adapter

 

 

I have read the reference manual and have done the following steps but i cant read the LIN data .

 

Is their any Application note or code example.

Has someone a good tip?

 

which is the correct way to initialise the Uart and to read the LIN data by ISR routine?
