AC and DC power single-channel measurement using STPMSx and STPMCx

Hello!

I need to measure AC and DC voltage, current and power using the same input depending on what type of voltage source the end user decides to connect to that channel. The same question asked Tom MacDonald here (https://community.st.com/s/question/0D50X00009XkYWlSAN/measuring-dc-power-using-stpm32-evaluation-board?t=1603263653338&searchQuery), but this question was closed without answer. Does ST or anyone here have any info/experience/application note for DC measurements using stack STPMSx + STPMCx? May be there are another solutions? I've also tried to use Microchip MCP39F501, but it has weak documentation about DC. With AC measurements works well, but I also need to measure DC as well.
