The Design and Implemation of Bluetooth HCI-UART Host Control Interface Based on FPGA
Guo Don · Microcomputer Information · 2010
Bluetooth, as a short-range wireless communications technology, has a tremendous development potential. This article tries on the application development of Bluetooth based on the HCI layer. At first, this paper introduces the structure and principle of HCI and UART of HCI. On the basis of the analysis and comparison of the advantages and disadvantages of the three types of in- terfaces USB, RS-232 and UART, a methond using hardware to design HCI-UART based on FPGA is given in the paper. The design is completed in the integrated design environment of Quartus II 9.0 and diveded into seveeral modules which is completed by use of hardware description language Verilog. The design is simulated and verified by Modelsim 6.4a.
