摘要
在全数字化高频大功率UPS中,大都采用两片或多片DSP与单片机共同完成较为复杂的控制和监控任务。文中主要就SC I串行通讯接口实现DSP与单片机串行通讯展开讨论,同时给出了利用SPI实现串行通讯的设计方案,分析比较两种通讯方式异同,给出了DSP与单片机串行设计的基本方法。
In total number high frequency high-power UPS, there are two or more pieces DSP and SCM accomplishing the control and supervision missions which are complicate. The paper mainly discusses the interfaces between DSP and SCM in SCI serial communication, at the same time this paper presents the design of SPI scrial communication and analyses the different between the two modes, contemporary presenting the basic way of serial communication design.
