  • Building Low Cost Virtual Instruments for Physics Research 
    Sonnadara, D.U.J.; Fernando, H.T.M.M. (1998)
    A virtual instrument is a combination of hardware and software elements that has the functionality of a stand-alone instrument. However, unlike the traditional instruments which are designed to carry out a specific task, ...
  • CPLD Based Simple Microprocessor for Data Acquisition 
    Wijesinghe, W.A.S.; Jayananda, M.K.; Sonnadara, D.U.J. (2005)
    This paper describes a simple microprocessor developed using a Complex Programmable Logic Device (CPLD), with an instruction set optimized for data acquisition applications. Most low-cost data acquisition systems are built ...
  • Development of low cost network based virtual instruments 
    Sonnadara, D.U.J.; Goonatillake, P. (2001)
    With the rapid expansion in IT, especially in the communication and networking areas, new products and instruments are being introduced into the market frequently. These instruments help researchers to explore their problems ...
  • Development of microcontroller based high capacity standalone data acquisition systems 
    Sonnadara, D.U.J.; Fernando, B.W.S.P.; Goonetilleke, P.C.C.P.W.; Fernando, I.M.K. (2002)
    A low cost, user-friendly data acquisition (DAQ) system was built using a microcontroller of the PIC family. The developed DAQ system consists of four separate ports to acquire data from external sensors, namely, a port ...
  • Microcontroller embedded web server with flash support 
    Sonnadara, D.U.J.; Goonetilleke, P.C.C.P.W.; Fernando, W.S.P.; Fernando, I.M.K. (2002)
    In atmospheric and meteorology research, constant monitoring and recording of weather parameters are often required. Especially, in today’s society, the demand is there not only to automate the monitoring and recording of ...
  • PC Based Data Collection and Process Control Systems for Research and Industry Applications 
    Sonnadara, D.U.J.; Jayananda, M.K. (1998)
    In Sri Lanka major research programs use donated computer controlled equipment with pre-developed hardware and software systems to collect and analyze their data. These systems are not developed further or changed even ...
  • Performance of parallel port based remote data acquisition systems in real-time data processing 
    Sonnadara, D.U.J.; Goonetilleke, P.C.C.P.W. (2002)
    A parallel port based remote data acquisition and process control system was built without on board RAM and programmable timer to test the effect on the performance when processing real-time data on a network environment. ...
  • Study of multipliers in programmable logic devices 
    Wijesinghe, W.A.S.; Jayananda, M.K.; Sonnadara, D.U.J. (2006)
    Hardware multiplier is a major component in many computational and DSP systems which are implemented in Field Programmable Gate Arrays (FPGA). Since there are no universally accepted methods, designers often need to construct ...
