Design of SPI to I2C Code Converter Using Verilog

Different components in an embedded system employ different communication protocols for the exchange of information. Every protocol has a unique data format. This research paper presents the design and implementation of an SPI to I2C code converter using Verilog. The converter is designed to communicate between two devices that use the SPI or I2C protocol. The design process involved the use of Verilog Hardware Description Language (HDL) to implement the converter's functional blocks. The converter's functionality was tested using a Xilinx FPGA development board, and the results show that the converter successfully converts data between the two protocols. The system was realized by comprehending the data transferred by the SPI master from its MOSI or MISO line, and the data was written onto the SDA line of the I2C device, as both devices are made to work on the same clock frequency. The SPI to I2C code converter design presented in this paper provides a simple and efficient solution for communication between devices using different communication protocols. The use of Verilog HDL allows for easy modification and customization of the code to suit specific project requirements.
