Pressure sensor
The LPS001DL is a high resolution, digital output pressure sensor packaged in an LGA
holed package (STMicroelectronics patent pending). The complete device includes a
sensing element based on a piezoresistive Wheatstone bridge approach, and an IC
interface able to take the information from the sensing element to the external world, as a
digital signal.
The STEVAL-MKI062V2 board uses an I
0xBA. The LPS001DL features two fully programmable interrupt sources (INT1 and INT2)
which may be configured to trigger different pressure events. In the STEVAL-MKI062V2,
only the INT1 interrupt source is connected to the MCU. The device may also be configured,
through interrupt pins; a data ready signal (Drdy), which indicates when new measured data
is available, therefore simplifying data synchronization in digital systems. The connection
between the LPS001DL and the STM32F103 is shown in

An I
STM32F103RET is available on the board.
As the STLM75 pins, A2, A1, and A0, are grounded, the slave address of the sensor is
settled to 0x90. The STLM75 has a dedicated open drain Over-Limit Signal/Interrupt
(OS/INT) output which features a thermal Alarm function. This function provides a user-
programmable trip and turn-off temperature, and it can operate in either of the two
selectable modes:
