激光电源中央控制器系统的通信设计

The Design of Communication in Central Control System of Laser Power

基于系统核心处理器TMS320F28335以及作为协处理器的FPGA,EP2C20Q240C8N,设计了一套用于激光电源中央控制器的通信方法.包括DSP与EEPROM的SPI通信、DSP与FPGA的总线通信、中央控制器与总控之间的RS485通信、中央控制器与下级模块CPU的CAN通信和I/O通信.

This Paper introduces the methods of communication based on the core processorTMS320F28335 and the Coprocessor FPGA EP2C20Q240C8N . These communication methods are used incentral control system of laser power, including SPI communication between DSP and EEPROM, BUScommunication between DSP and FPGA, RS485 communication between central control system and Mas-ter Controller, CAN communication and I/O communication between central control system and the lowermodules.
