Comparator

VDD_ANA is divided by the resistor bridge of LDR VT9ON1 & 8.2K resistor and connected
to PA0 (COM7_IN+/COM1_IN-/ADC IN1). VDD_ANA is also divided by the RV2
potentiometer and connected to PC1 (COM7_IN+/ADC12).

Temperature sensor

A temperature sensor, STTS751, is connected to the I2C2 bus of STM32F303VCT6 by
setting JP5 and JP6 jumpers, as shown in
Table 17.
