摘要
Abstract
In order to meet CAN network control system for real-time and reliability requirements , this paper presents a smart and multi-channel CAN card design scheme based on FPGA .The variable-byte SPI master mode interface cir-cuit is designed through FPGA , the hardware structure is simplified , and a dual-port RAM implement PCI bus and network data exchange are designed .PCI interface circuit is designed based on the CH 365 and it can be shared with ISA mode.The transformer isolation circuit is designed that can implement lower power and higher reliability .The mi-croprocessor is designed on the board that abides by TTCAN protocol can automatically realize CAN data exchange , and it also can be used as a normal card , eliminating the need for complex drive call , and easy to use .Final designed experimental test reliability and real-time of board that worked under the automatic transmission mode , the results meet the requirements .关键词
