In this paper the authors intended to read the analog data from the field sensors to the ADC evaluation board through FPGA interfacing and store the data into memory. VHDL code is developed to program the FPGA. The analog input required by the ADC's is given through a single multiplexer. ADC converts the analog data into digital input and sends to the MCU. MCU processes the received digital input and the processed data is sent to the FPGA through Serial Peripheral Interface (SPI). The FPGA is programmed using VHDL Language for interfacing the MCU unit for configuring the ADCs and read the field data converted to digital by the ADCs.
