ISF2P1_KINETIS_RELEASE_RN, 1.0, 11/2015

Freescale Semiconductor, Inc.

4.2 ISF v2.0 features

The middleware is integrated into the Freescale Processor Expert technology. This allows the

middleware to be autogenerated for specific hardware configurations.

By using Processor Expert, ISF is abstracted from the specific MCU hardware. ISF can be configured

for almost all of the Kinetis processors, those with a PIT timer. Implementations for two Kinetis

processors, the KL25Z and the K64F, have been tested and verified for this release.

The middleware includes a set of Processor Expert components downloadable from the Freescale ISF

website.

The ISF_Core component is a library of components. Some of the components of interest within the

ISF_Core library are:

Protocol Adapters

•

I2C for sensor communication

•

SPI for sensor communication

•

UART for host communications

Sensor Adapters using generic APIs based on sensor types

Accelerometer

•

FXOS8700

— MMA865x

Gyroscope

•

FXAS21002C

Magnetometer

•

MAG3110

•

FXOS8700

Streaming protocol allows wider options for communicating sensor data back to the host. CRC error

checking is included as an optional feature.

DSA-Direct API replaces the functionality of the Sensor Manager and can manage sensor data directly.

Register-level access to the sensors is provided. Optimization of memory usage is implemented.

4.3 ISF v1.1 features

The following features from ISF v1.1 are available in the new release.

•

The middleware acts as a sensor hub, providing sensor data from external sensors.

•

CodeWarrior project files are available allowing users to begin with a working project.

•

Automated installation is provided to enable ease-of-use.

•

Synchronization is now provided during framework initialization to ensure that initialization is

complete prior to executing application code.

•

Application-specific commands are supported by the Command Interpreter.
