The FPGA-based integrated communication interface provided by the invention is high in integrity, good in design flexibility, strong in extended function, reliable and stable in communication performance and high in speed.

Description

technical field [0001] The invention relates to an integrated communication interface based on FPGA. Background technique [0002] With the development of technology, the degree of automation in the industrial field is getting higher and higher, and there are more and more smart devices. This requires information interaction between different smart devices. Because different application environments require different communication methods, this is It is required that the designed electronic products should provide various communication interfaces for customers to choose. In the current design of electronic products, most of them use a separate communication interface design method, that is, RS232 uses DB9 pin port, Ethernet uses RJ45 interface, RS485 uses two-pin plug terminals, etc. Although these interface designs can meet the requirements of the product work site It is necessary, but it will have adverse effects on product appearance structure design, PCB board design, m...
