Introduction
This document explains the functioning of the multiple temperature sensors and RTC demo
which is based on a motherboard and daughter card approach. The complete system
consists of one motherboard having an STM32F102xx microcontroller and different
daughter cards having a temperature sensor and RTC. The temperature sensors supported
by this system are:
■
STLM20
■
STTS424E02
■
STTS75
■
STDS75
■
STLM75
■
STCN75
■
STTS751
■
STTS2002
RTCs supported by this system are:
■
M41T82SM6
■
M41T83SQA6
■
M41T83SMY6
This board operates in USB powered mode with a graphical user interface (GUI). The
graphical user interface is used to access the registers and demonstrate the features of
temperature sensors and RTCs.
