The invention discloses a realization method of supporting Arduino IDE development by a Xilinx FPGA, and belongs to the field of embedded technology. The realization method can realize an effect of downloading a program, which is written in an Arduino IDE, into an FPGA board card to enable the FPGA board card to have related functions of an Arduino board card, and include: carrying out hardware logic design according to functions needing to be realized; writing a corresponding software drive for added hardware logic; transplanting a compiling system and a downloading system of Xilinx SDK intothe Arduino IDE; using a drive function of the Xilinx SDK to rewrite Arduino IDE library functions; and writing the program in the Arduino IDE for testing. The method adapts to a development trend ofthe FPGA, can facilitate FPGA development of a user, reduces an FPGA development threshold, and also lays a foundation for further developing functions of the aspect by succeeding persons.
