STMICROELECTRONICS LAUNCHES NEW ISPU TOOLCHAIN AND SOFTWARE PACKAGE

STMicroelectronics has released a toolchain and accompanying software package for programming the intelligent sensor processing unit (ISPU) embedded in the latest-generation intelligent MEMS IMUs, ISM330IS and LSM6DSO16IS. The toolchain and software help employ the ISPU to handle motion-related workloads such as activity recognition and anomaly detection directly in the sensor. This permits reducing system power and latency, offloading the local microcontroller, and uniquely specializing the behaviour of the sensor to the application.

Using the ISPU toolchain, developers can program the sensor’s intelligent processing unit using the familiar and widespread C programming language. They can choose to work from a command line interface (CLI) or an Eclipse-based environment like STM32CubeIDE, and to use a graphical user interface (GUI) such as AlgoBuilder and Unicleo.

The X-CUBE-ISPU software package contains templates and example projects as well as ready-to-use libraries that help developers quickly understand how to use and program the sensors’ ISPU and can be used as a starting point to implement custom algorithms. Pre-built files are also available, which lets users load the X-CUBE-ISPU examples directly into the sensor using one of the GUIs, with no coding required. In addition, a GitHub repository is available providing more examples, tutorials, and other development resources.

ST’s ISM330IS and LSM6DSO16IS inertial modules contain an always-on 3D accelerometer and 3D gyroscope with the embedded ISPU. They feature low power consumption, drawing as little as 0.46mA in low-power mode, and low noise at 70μg/√Hz in high-performance mode. Sensor hub functionality allows them to collect data from up to four additional external sensors. An embedded temperature sensor is also included, and each device is housed in a compact 2.5mm x 3mm x 0.83mm plastic land grid array (LGA) package.
