Abstract:

This paper introduces the development of Z85C30 Device Driver which supports multi-protocol and multi-chip.First,a brief introduction to Z85C30 chip and registers is given.Then,according to the design frame of driver of character device,the implementation of this driver is expatiated.The pointer of core interrupt process function is used to connect with the fact core interrupt process function of each protocol,which individualizes the process of each protocol.For on-line configuration of parameters of each channel in user space,the sccs_ioctl function is designed as API.Finally,a module of Z85C30 device driver is obtained via cross-compiling.

Key words: Linux;Z85C30;device driver;multi protocol
