Description

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

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.
