Hello,
I whant to build a 3 phase meter from the EVALSTPM-3PHISO. The Data that is computed should be send to a display interfacing with an lcd1602 (HD44780). Later a graphical display will be used. But to get a product that is working we have to handle the firmware package that is downloadable for the evaluation board. We are looking for a description to the STSW-STPM004 Firmware. We have to implement functions like energy counting and tracking, saving data to a file during one day of measuring.
We know that the firmware is not using the internal DFSDM (sigma delta filter) because the STM32F413 only has 2 hardware implemented filters. So we would need a documentation how this emulation is done in the firmware to build this solution for our use cases (Initialisazion of the STM32 clock and data channels for the 3 sigma delta ICs).
Thank you in advance,
BR
