The STSW-STPM3PHGUI evaluation software is a graphical user interface to access information calculated by EVAL-STPM3x-3PH FW.
Energy and power (for each phase and cumulative) voltage and current RMS are calculated by the STM8S903K3, using metrology data from the two STPM3x energy metering ICs on-board, and then displayed on the GUI.
The application has a unique work area where the user can read FW calculated data, or access directly each metrology device to read measured data or to read/write configuration registers.
The application parameters (such as sensor sensitivity, AFE parameters) can be configured to calculate the power, current and voltage.
The GUI allows also data read/saved to the EEPROM.
The connection to a PC uses a USB cable A/B, by which the board is also powered.
