Product overview
Description
The STSW-ISOSD001 firmware is embedded in the EVALST-3PHISOSD evaluation board to implement 3-current sensing for motor control application with low-cost shunt current sensors.
The firmware library implements:
The firmware exploits the DFSDM filters of the STM32F413RH to convert the three bitstreams into 24-bit current data, at 200 us rate.
The STPM3x-like registers allow the application access to the virtual device, which can be read/configured by the hardware interface layer.
The firmware also implements a virtual COM port communication to easily access the internal parameters to read measured data, to modify the internal configuration for a high flexibility of the application, and to calibrate the board.
