Abstract
Embedded control programmable hardware and Windows-based Virtual Instruments (VI) simplify the design of automation in R&D laboratories. With minimal hardware and maximum support of software, the automation becomes more readily achievable (Jayapandian, J. Curr. Sci., 25 March 2006, 90(6) 765–70). A novel design is described for the control of a Siemens X-ray Diffractometer. The automation is achieved with custom-embedded hardware using an 89C2051 microcontroller that is compatible with a Universal Synchronous Bus port and a VI created using LabVIEW.
