Temperature sensor
A temperature sensor STLM75M2E is connected to the I2C bus of the STM32L152VBT6
through two transistors to support a wide voltage range, from 1.65 V to 3.6 V.
JP10
JP11
Jumper
PB4 is connected to JTAG connector CN9 (TRST) when JP10 is set as
shown (default setting).
PB4 is connected to LDR when JP10 is set as shown.
PB5 is connected to I2C_SMB, the interrupt output of temperature sensor U18 when JP11
is closed (default setting).
PB5 is disconnected from I2C_SMB but remains connected to COM_IN+ when JP11 is
open for comparator application.
