Introduction
This user manual explains the functions of the multi-device temperature sensor
demonstration board which is based on a motherboard and daughter card approach. The
complete system consists of the motherboard with an ST72F651 microcontroller and
daughter cards with temperature sensors. The temperature sensors supported by this
system are:
■
STLM20
■
STTS424E02
■
STTS75
■
STDS75
■
STLM75
■
STCN75
This board can operate in 2 modes:
■
Standalone / external-power mode
■
USB-powered mode / full-featured mode
The board's configuration and operation in both modes is explained in different sections. To
select the desired mode, there is a power selection switch (SW5) on the board which
enables the appropriate selection. When this board is connected to a computer through the
USB cable then it also behaves as a mass storage device. The default state of the board
(with USB connection) is mass storage mode. It switches to temperature-sensor mode using
a graphical user interface (GUI).
