Product overview

Description

The FP-IND-DATALOGMC function pack for STEVAL-STWINBX1 and EVLSPIN32G4-ACT is a powerful integrated toolkit for the next generation of smart actuators. It is derived from a FP-SNS-DATALOG2 function pack and it allows the collection of heterogeneous data, combining STWIN.box sensor information with STSPIN32G4 motor control data and it provides a comprehensive view of the system’s operational conditions. This enables both real-time monitoring and accurate performance assessment.

EVLSPIN32G4-ACT is designed to drive a variety of three-phase brushless DC motors (not included in the kit) and ready for FOC control algorithms. See UM for further details and installation guide. The list of supported motors is provided in the motor control SDK documentation (X-CUBE-MCSDK-6).

The function pack includes a Python GUI, hsdatalogMC_GUI that communicates with the STEVAL-STWINBX1 via USB allowing the user to control the motor (start/stop commands, set velocity) and select a combination of motor control telemetries and sensor data to be logged. The STEVAL-STWINBX1 communicates with the STSPIN32G4 MCU via serial port (UART), using the motor control protocol (MCPv2). This protocol allows both system configuration and data logging.

FP-IND-DATALOGMC is based on application-level modules (SensorManager, TagManager, DPU digital processing units) that can be reused and extended to build its custom application. To enable this modularity, the function pack has been built on top of eLooM, an embedded light object-oriented framework for STM32 applications specifically designed for embedded low power applications powered by STM32.

The DATALOGMC application can save data to a microSD™ card (secure digital high capacity - SDHC) formatted with the FAT32 file system, or stream data to a PC via USB (WCID class). A Python SDK, provided within the function pack, makes it easy to read back and process sensor and motor data acquired using FP-IND-DATALOGMC, a few ready-to-use scripts, and notebooks are provided.

The software is also available on GitHub, where the users can signal bugs and propose new ideas through [Issues] and [Pull requests] tabs.
