The LIN low level driver provided by the chip manufacturers cannot cover all the chips, in some cases users have to modify or design the LIN low level driver by themselves. To address this problem, a common framework of the driver was proposed and base on it research was carried out to realize the unconditional frame communication. The background knowledge of the LIN bus was introduced; it was pointed out that a common LIN driver framework should be based on UART/SCI, timer module and interrupt. The design of the driver was divided into configurable part and the fixed part, detail discuss of the latter one was carried out, especially on the basic types, the interrupt functions and the Core API. The feasibility of the framework was verified through the communication between the test circuit board and the Emulin. Analyses show that this method is applicable to many chips and can accelerate the development progress.
