Remotely Controlling The Parameters Using Labview Through Zc702 (XC7Z020CLG484 Soc) Can Interface

Abstract

This application will be used to control various parameters such as Gain, Filter Frequency etc. in Electronics and Data Acquisition System. We will be using CAN Interface for remotely controlling and LabVIEW software for user interface. The CAN protocol provides high reliability, which is one of the important features in DAQ systems. The prototype application has been designed for the ZC702 evaluation board which consists of the XC7Z020CLG484 SoC chip, which has two ARM Cortex A9 processor cores, FPGA and an inbuilt CAN controller. Since most of the controller such as CAN, Ethernet, USB and I2C are available on the chip, it reduces the external ICs required for the system, thereby making the system compact. The Xilinx SDK is used to write a code in C for the Cortex A9 processor. The FPGA is programmed in VHDL to produce the control signals and data for the electronics and data acquisition board. The XC7Z020 SoC, optimizes the communication between Processing System and the Programmable Logic. The prototype application has been implemented and tested in the lab. The paper will describe about the hardware and the software for the prototype application.
