Real Time Monitoring of 3 Axis Accelerometer using an FPGA Zynq®-7000 and Embedded Linux through Ethernet

Abstract

This paper introduces the use of a Field Programmable Gate Array (FPGA) with Zynq-7000 architecture and embedded Linux, as a digital tool to perform real-time remote monitoring of Internet-connected devices, using sensors that support SPI communication, the advantage of implementing the SPI protocol in the FPGA is that it can use several sensors that support this protocol even joining them at the same time. The incorporation of an embedded Linux operating system opens the possibilities of communication and execution of software as if it were a personal computer, as an example in this work, a 3-axis accelerometer is used. By integrating the above elements, a digital tool capable of covering the need for remote monitoring in real time is accomplished with a web server and connecting the FPGA through the Ethernet port by the TCP / IP protocol.
