The I2C address of the temperature sensor is 0b1001000.
STTS751 will work properly when VDD > 2.25V.
Note: The temperature result measured from PT100 would be a little higher than the ambient
temperature due to the power dissipation of components on the board.

Display and input devices

The 240x320 TFT color LCD connected to the SPI2 port of STM32F303VCT6 (shared with
the MicroSDcard and Serial EEPROM) and four general-purpose color LEDs (LD1, LD2,
LD3, LD4) are available as display devices. The 4-direction joystick (U27) with the selection
and key button (B2) are available as input devices.
The LCD can be enabled by the chip select signal PE0; this signal should be set as an
open-drain output pin in STM32F303VCT6. All joystick signals should be set as a pull-down
input pin in STM32F303VCT6.
Table 18.
Note: The bi-directional voltage translator is implemented on the SPI MOSI signal between
STM32F303VCT6 and the LCD to support the 3-wire serial interface of the
AM240320LGTNQW-01H LCD panel. The direction of this voltage translator is controlled by
the PE14 I/O (the PB15 I/O is used as a MOSI when PE14 is high, or as a MISO when PE14
is low).
