| Abstract: | In this paper,a master-slave CNC system that consists of master controller based on ARM,slave controller(motion controller) based on DSP and FPGA was briefly introduced.Based on this,several communication solutions between the master controller and slave controller were discussed and compared in detail.Then,a high-speed serial communication based on RS-485 was proposed.In this solution,a field-programmable gate array(FPGA) chip was used to expand the multi-channel universal asynchronous receiver transmitter... |
