3.4.1 Using the GUI software
In order to use the GUI of our STEVAL-IHT001V1 kit, a recent version of Windows®, such
as Windows 98, Windows 2000 or Windows XP must be installed on your computer. The
version of the Windows OS installed on your PC may be checked by clicking on the
“System” icon on the Control Panel.
To install the PC software (GUI) tool:
●
Put the companion CDROM into the PC.
● Browse the CDROM directory to locate the GUI setup executable.
●
Double-click on the GUI setup executable file.
● Follow the instructions as they appear on the screen.
Figure 7 explains how to connect the different STEVAL-IHT001V1 kit boards and the
computer.

An insulated interface is required in order to control the different parameters of the fridge
(
Figure 8 ). The SCI insulated interface board is used in order to insulate the PC from the
STEVAL-IHT001V1 Kit Board and converts the RS-232 levels (about +10 and -10V) to TTL
voltage (0 and +5V) used by MCU, and vice versa, without requiring anything else than a
+9V power supply.
