Abstract
The protocol and principle of I~2 C-Bus were introduced.The framework of I~2 C-Bus based on FPGA was proposed.The idea of nesting state-machine of complicated timing-circuit and the hardware description of I~2 C-Bus interface by Verilog HDL were presented.The simulation of designing under the Xilinx ISE 6.1i development platform combined with ModelSim SE 5.7 was made and the operation on I~2 C device based on SpartanⅡXC2S100 was implemented.
