V.C.10. Single Chip Embedded Experimental
Automation Design
An inexpensive embedded
automation design for Raman
spectrometer system shown in
Fig.1, has built with a single
Programmable System On-
Chip (PSoC), a Cypress Micro
System's mixed array
microcontroller. This
automation system allows the
on-line acquisition of
spectroscopic data and the
control of the experimental
setup operation, using PC as a
window based graphical user
interface (GUI). The menu
driven user-friendly software in
virtual instrument (VI) control
program written in LabVIEW
ver.7.1, a graphical language,
interacts with the embedded
single chip design for the total
automation of the experiment.
The user friendly menu driven
virtual instrument program
interacts with the embedded
PSoC design through its USBserial
interface.
Fig.2 shows the front panel of
the PSoC based menu driven
user-friendly virtual instrument
program with a acquired
Raman spectrum in zinc
cyanide, Zr(CN) 2 acquired in
the range of 2200 cm -1 to 2240
cm -1 for a preset time of 5
seconds in steps of 0.5 cm -1 .
The menu driven GUI program
has the facilities like (i) storing
the data in the user specified
file path, (ii) loading the
previous spectrum form the
user file path, (iii) automatically
configure the initial, final and
step wave number on the graph
immediately after the user entry,
(iv) print spectrum, (v) clear
spectrum and (vi) functioning
