Digital Interface & Software

A USB cable is provided to interface the NCD9830 board

to computer. A software file NCD9830_REV5.exe along
with its associated .hex file is also provided. Save the .exe

file and the .hex file in the same folder for proper interfacing
of the device with the software. Double click the
NCD9830_REV5.exe file and the user graphical interface
window will open as shown in Figure 5 below.

Figure 5. Graphical User Interface

This small green square shows that firmware is
downloaded successfully. If it is red check USB
connection and address settings.

Select “Measurement mode”, and “channel Select”

appropriately from drop down menu. The power mode
needs to be at “Int Ref On, ADC On” to allow operation with

internal reference. Check Enable Averaging for a better
averaged result of the output. Check Enable Graphing to see
the output value graphically as shown below in Figure 6

.
