摘要
文章设计并实现了一种适用于ARM与DSP之间串行通信的通信协议,采用RS-485总线标准,硬件接口简便,通信可靠性高,并讨论了其软硬件的实现,可用于数控系统中。最后在ARM作为主控制器,DSP和FPGA作为从控制器的数控系统中验证了该协议在串行通信中的可靠性。
This paper introduces a serial communication protocol suited for the communication between ARM and DSP, based on RS-485 buse standard. The interface of hardware is simple and the dependabili- ty of communication is high. The design of the software and hardware of the serial communication proto- col is discussed. This protocol can be applied to CNC system. At last, the reliability of the serial com- munication protocol is proved in CNC system, which suggests ARM as the master controller and uses DSP and FPGA as the slave controller.
