intelligent IO-Link device application can be
implemented.
CD-ROM delivered with the board contains
several firmware examples (IAR projects). The
examples demonstrate usage of MEMS sensors
as IO-Link devices and a binary actuator
application.
IO-Link device software stack is available from our
partner (third party) – MESCO Engineering
GmbH.
The STEVAL-IFP014V1 is a demonstration board
designed for evaluation of “IO-Link device”. It can
be utilized with either sensor or actuator
functionality depending on the firmware. It is
based on IO-Link physical layer (L6362) controlled
by STM32 (STM32F103T6U6), 32-bit Flash
microcontroller based on the ARM® Cortex™-M3.
The design of the board allows evaluation of either
IO-Link physical layer (L6362) or complete IO-Link
device application.
The board is assembled with two sensors:
LIS302DL MEMS accelerometer LIS302DL
MEMS accelerometer and LY530AL MEMS
gyroscope connected to STM32 microprocessor
via SPI interface. Using STM32 and L6362 an
