Implementation of I2C and SPI communication protocol for temperature and acceleration measurement at FPGA

Abstract

This document presents the development of the I2C and SPI communication protocols in the VHDL hardware description language, its implementation was carried out on the Xilinx Nexys 4 DDR FPGA board with temperature sensors (ADXL362) and accelerometer (ADT742). whose chips are integrated into the board. The temperature sensor communicates with the I2C protocol and the accelerometer with the SPI protocol, both communications were integrated into the project and can be selected through the switches provided by the FPGA board. The experimental results carried out demonstrate the reliability of the communication given the precision of the data obtained.
