The objective of this paper is to design and implement an data acquisition system (DAQ) by using serial RS-232 and SPI communication protocols PC platform. The developed DAQ system should be able to acquire both analog signals as well as digital signals. The system converts the analog signals into digital data and send the data into the computer using RS-232 serial communication for further processing. The development of the system has been divided into two phases. The first phase is to the design of SPI interface, while the second phase is to the design of RS-232 interface. The SPI interface deals with the ADC and amplifier communication with FPGA and the RS-232 interface deals with the communication between PC and FPGA. The SPI and RS-232 communication protocol have been developed using C programming language Data acquisition system project is a fine combination of analog and digital electronics. This project is designed so as to fulfil the requirements of the industry applications, home applications. The project consists of parameters monitoring, parameter storage which is also known as Data Logger. PC interface is one of the main features of the project in which various data like value of parameters, date and time are sent to the PC. Microcontroller as a main component of the project. Now a Microcontroller has become a main component of many of the electronic circuits. Also Liquid Crystal Display (LCD) and EEPROM is used on major basis for the display and storage purpose. I2C bus protocol is used while interfacing 8051 with EEPROM. This project which will consist of two basis modules. First is “Data monitoring” & other is “Data Storage”.
