摘要
设计复杂双CPU系统的关键是两者之间的接口与数据通信问题。针对单片机89C51与TMS320LF2407ADSP构成的双CPU系统,本文提出了一种简单可行的串行通信方式。本文不仅介绍了两者之间的硬件连接示意图,而且完成了两者通信的初始化设置,并且给出了完整的串行通信的软件流程图。
The key to designing a complex double-CPU system is the interface and data communications. This paper proposes a simple and practical serial communication way aiming at the system which consists of a 89C51 microeontroller and a TMS320LF2407A DSP. This paper not only introduces the hardware connection diagram, hut also completes the initialization settings of the communications, and gives a complete serial communication software flowchart.
