The LIN 2.1 Driver is designed to support certain microcontrollers of S12 and S08 families. Please refer to Release Notes to see which.
The driver is provided with a series of demo projects, which were tested and working on both master and slave side.
In order for the driver to parse a frame or signal, that frame and signal has to be defined in the node property files according to the LIN 2.1 standard, otherwise you could see the data in the input buffer, but the driver cannot map them to a logical presentation.
