摘要
以VFD控制器PT6311为例,介绍了其内部结构、工作原理,并且详细阐述了在ASIXOS操作系统下面开发驱动程序的过程和方法。同时给出基于SEP3203微处理器的VFD控制器PT6311中断方式的驱动程序。结果表明,本模块刷新时间Tr<200ms,可以运用于税控收款机,银税一体机和音响等方面。
This paper takes VFD controller PT6311 as an example and introduces its internal structure and how it works. The process and method of device driver is elaborated in embedded ASIXOS operation. The device driver based on interrupt of VFD controller PT6311 on SEP3203 is given. The conclusion is that the time of refreshing is under 200 ms and the module could used in Fiscal cash register, Bank and Fiscal integrated register and HI-FI Components.
