Introduction
This user manual describes the STEVAL-MKI032V1, STM32-MEMS demonstration board which
serves as interface between the STM32™ demonstration board (STMicroelectronics™
STM3210B-EVAL, STM3210E-EVAL, IAR KickStart Kit™ for STM32) and the MEMS demonstration
board (any STEVAL-MKI0xxVx compatible with DIL24 socket).
The STM32-MEMS demonstration board comes with a development kit: a firmware package for the
STM32 microcontroller family, which includes a library, examples, demonstration applications and
application hints. The aim of this development kit is to provide a simple interface to analog and digital
MEMS accelerometers together with demonstration applications that utilize this interface.
The STM32 family of 32-bit Flash microcontrollers is based on the breakthrough ARM
a core specifically developed for embedded applications. The STM32 family benefits from the
Cortex-M3 architectural enhancements including the Thumb-2
performance with better code density, significantly faster response to interrupts, all combined with
industry-leading power consumption.
The STM32 family is built to offer new degrees of freedom to MCU users. It offers a complete 32-bit
product range that combines high-performance, real-time, low-power and low-voltage operation, while
maintaining full integration and ease of development. Compatibility of pin-assignments, peripherals
and software across all STM32 devices is a core technical feature throughout this family of
microcontrollers.
The STM32 family of microcontrollers is supported by a complete range of high-end and low-cost
demonstration, software, debugging and programming tools. This complete line includes third-party
solutions that come complete with an integrated development environment and in-circuit
debugger/programmer featuring a JTAG application interface. Developers who are new to this family
and the Cortex core can also benefit from the range of starter kits that are specially designed to help
developers evaluate device features and start their own applications.
Sensors based on MEMS (micro electro-mechanical systems) technology are conquering many
market segments, ranging from mobile communication and computing to consumer electronics,
healthcare and industrial. ST offers a portfolio of MEMS-based linear accelerometers able to sense
acceleration or vibration in one, two and even three axes. Leveraging on proprietary MEMS technology
and worldwide recognized success on acceleration sensors, ST introduces new high-performance
MEMS gyroscope sensors.
